This problem obviously had a direct impact on water management of East Water. also has direct impact on water management of East Water. Therefore, the main forum used by East Water for communicating the water situation, clarifying the measures against drought, and creating understanding among the groups of water users is the Water War Room, which consists of the Royal Irrigation Department, Provincial Waterworks Authority, and industrial operator group as members. The key measure to help the Eastern region withstand the drought crisis is to accelerate the construction of a pumping station and untreated water pipeline from Prasae - Nong Pla Lai reservoir and the construction of untreated water pipeline from Nong Pla Lai - Nong Kho 2 Reservoir to divert water faster than scheduled. Additional water from the Bangpakong River and private ponds in Chonburi Province was also reserved to ensure that there is enough cost water source for all sectors throughout the years 2016 and 2017, although some projects suffered a slight delay from the plan.

SUSTAINABILITY REPORT 2016

We have to accept that “Global warming” is the most critical issue of natural disaster worrying the world and Thailand now as it is the major cause of climate change. Some areas turn into deserts with food and water shortage. Some areas experience heavy floods. Some coastal areas are lost permanently. In Thailand, over the past two years (2015-2016), we have suffered a severe drought crisis resulting from the “El Nino” phenomenon, which continuously caused a lower rate of rainfall that posed as a risk of eventually creating a water shortage problem.

Summary of major risks in 2016: 1. The amount of cost water is inadequate due to the drought

18

The El Nino phenomena had an impact on the amount of rainfall in 2016, which fell below average and thus impacted the water level in the water sources of East Water, especially in the Chonburi and Chachoengsao areas. East Water closely monitored the water situation in the Eastern region, and arranged meetings in the Water War Room with the Royal Irrigation Department and the industrial sectors in order to plan the water usage and an adequate water supply. The Company also implemented controlling measures to manage the risks as follows: 1) Divert water from Prasae reservoir to Nong Pla Lai reservoir to ensure a sufficient water supply for Rayong, Bo Win, Pluak Daeng, and Chonburi areas.

2) Stimulate the water pipeline project of Nong Pla Lai-Nong Kho Line 2 to divert more water from Nong Pla Lai reservoir to Chonburi area.

3) Purchase additional raw water from private ponds in Chonburi area to supplement the cost water amount in Chonburi and Chachoengsao areas.

2. Amount of cost water is inadequate for business expansion in the future

From the expansion the industry in the East and additional economic stimulus measures, for example, the Eastern Economic Corridor (EEC), it is expected that East Water will have the chance to expand its investment in order to earn income from the raw water and tap water business in the country, especially in the Eastern areas (Chachoengsao, Chonburi, Rayong). East Water estimates that the cost water currently available may not be adequate for the expansion of the country’s economy. Thus, East Water has implemented additional controlling measures to manage such risks as follows: 1) Review the plan for development of water resources and water pumping system in the 10-years period.

2) Improve the efficiency of water diversion from Bangpakong River.

3) Conduct a feasibility study on water pipeline project in Chonburi area.

4) Request for additional water allocation from the Royal Irrigation Department.

5) Monitor the development project of Tab Ma untreated water storage pond in order to increase the cost water in Rayong area by using the reserved water sources of East Water in the future. The contractor is currently in the process of negotiation to resolve the problems and obstacles in the operation.

6) Coordinate with relevant agencies, such as Office of National Economic and Social Development and Provincial Waterworks Authority to support water management as a whole to respond to EEC policy ** Refer to details in the 2015 Annual Report • Good Corporate Governance • Anti-corruption • Business Ethics • Assessment of the Adequacy of the Internal Control System

Sustainability of Eastern Water System (EN8)

Water management by Water Grid “Water” resource is the fundamental factor in the stability of life, and is the fundamental factor stabilizing the life and is the key component to the entire production process both in agriculture and the industry. However, at present, the climate variability causes global warming and drought to expand rapidly, affecting rainfall and river water each year. Thus, the water management to be adequate for the use of all sectors is very crucial and necessary.

East Water, as a service provider of untreated water through large pipelines with 24 years of expertise, and as one of the government’s mechanisms in developing the water infrastructure in the Eastern region, considers “water” as a “Water Security” that directly impacts the organizations’s stability - one that has a direct link to the development of the nation’s economy, especially in the Eastern region, which is densely populated and is a tourist destination. It is also a major industrial area that boasts one of the country’s highest average income per capita, ranking second only after Bangkok and its perimeters.

Water Sources Managed by East Water

32

Water management by Eastern Water Resources and Development Public Company Limited covers 3 provinces; Chachoengsao, Chonburi, and Rayong, and is mainly distributed for consumption and the industrial sector. Water sources are divided into main water sources and reserve water sources.

The main water sources of East Water refer to the water sources that have been allocated by the Royal Irrigation Department (Irrigation Office 9) including the water sources which Eastwater can pump for use each year, with the amount of cost water matching that of the seasonal river water, which come from Nong Kho Reservoir, Dok Krai Reservoir, Nong Pla Lai Reservoir, Prasae Reservoir, as well as water pumped from the Bangpakong river and private water sources.

Reserved water sources of East Water refer to the water sources reserved for the purpose of stabilizing the main water sources, and needs to be planned and carried out in advance. They will be used in cases of inadequate water in the main water sources, and during water shortages. Reserved water sources are the Samnak Bok reserved raw water pond, Chachoengsao reserved raw water pond, and Bang Phra Reservoir.

The Office of Regional Irrigation 9 schedules an annual meeting to allocate water for those licensed to use water, excluding the agricultural sector.

to allocate water. The annual water allocation period begins in November and ends in October of the following year. A review meeting is held every 3 months to allocate additional water. In the years 2015-2016, East Water was able to efficiently manage the allocated water under an extreme drought crisis due to the El Nino phenomenon that occurred continually, by cooperating with the Royal Irrigation Department to closely monitor the water situation.

This joint effort resulted in an overall effective water management for the maximum benefit of the Eastern region, which was able to avoid the drought crisis.

East Water will only pump water from the Bangpakong river in the flood season. In 2016, East Water pumped water from the Bangpakong river during July and December with the aim of supplying water to consumers and industrial users mainly in Chachoengsao. Some part of the water was diverted to the Bang Phra reservoir and Samnak Bok reserved water pond in order to reserve the water supply for users in the Chachoengsao and Chonburi areas during the dry season.

Details of the amount of water allocated to East Water, and the amount of water pumped for usage in the years 2015-2016 are shown in the table below.

Development plan on the cost water sources for stabilizing the Raw water sources East Water has prepared a short term, medium, and long term development plan for the development of cost water sources to stabilize untreated water sources, and thereby reassure customers for the next 20 years.

In 2016, the Company has adjusted the water source development plan from the previous year to conform to the current situation due to the delay in the construction project to develop Klong Thab Ma untreated water storage pond, and to avoid any impact on water users, as detailed in the chart below.

As for the progress of the construction project to stabilize East Water’s pipeline network in 2016, the work was a continuation from the year 2015 and consists of 2 projects, which are:

(1) A project to build a water distribution pipeline from Prasae Reservoir to Nong Pla Lai Reservoir is scheduled to be complete on time. The diversion capacity of raw water will be increased by up to 70 million cubic meters, thus increasing customers’ confidence in the water management system. It has continued to pump water diversion to the present.

SUSTAINABILITY REPORT 2016

EASTERN WATER RESOURCES DEVELOPMENT AND MANAGEMENT PUBLIC COMPANY LIMITED

The operational plan for stabilizing the pipeline network of East Water consists of: 1) Planning to develop the cost water sources 2) Carry out construction projects to increase the efficiency of the water supply system according to the plan.

3) Coordinating with relevant agencies and pre dicting the weather in advance

(2) The Nong Pla Lai - Nong Kho raw water dis tribution pipeline No.2 is being built to meet future water demands in the Chonburi area and in the Pluak Daeng - Bowin area. The project began on 3 December 2015 and is scheduled for final completion in 2017. In the meantime, East Water is trying to speed up the installation of the pipeline system before May 2016 to alleviate the upcoming water scarcity problem.

Once complete, the pipeline will be able to distribute 50 million cubic meters of water per year.

East Water continues to work with the Royal Irrigation Department and other relevant organizations to develop up-to-date plans for efficient water distribution. For instance, attending the Water War Room Meeting for the Eastern region and coordinating efforts with the Department of Royal Rainmaking and Agricultural Aviation

The implement of measures to support the water shortage in 2016 1. Coordinated with the Royal Rain Operation Agency in the Eastern region through its ope ration center in Rayong Province during May and September 2016.

2. Diverting 98.39 million cubic meters of water from Prasae Reservoir to Khong Yai, and diverting 3.91 million cubic meters of water from Prasae Reservoir to Nong Pla Yai Reservoir.

3. Increased water reserves in the Bang Phra Reser voir by pumping water diversion from Bang Pakong River of Eastwater 15.48 million cubic meters.

4. Reduced water distribution from Rayong to Chonburi, and utilized water in the Chonburi area to its full capacity 5. Accelerated the construction of Nong Pla Lai Nong Kho 2 raw water pipeline in order to supply water to Chonburi and Pluak Daeng-Bowin areas faster than scheduled.

6.Procured additional private water sources which added 4.5 million cubic meters of reserve water.

At the end of the rainy season in 2016, the water situation of Bang Phra and Nong Kho reservoirs remained in the average, lessening the risk of a water shortage in 2017 in the Chonburi and Chachoengsao areas when compared to 2016.

Nonetheless, East Water has prepared measures to prevent and resolve water shortages, which are, to expedite the Nong Pla Lai - Nong Kho 2 raw water pipeline construction project, to find additional sources of untreated raw water from private ponds in the Chonburi area, and to optimize the efficiency of water pumping, mainly from Bangpakong river .

The application of technology in water management The most effective indicator of water management efficiency is water loss quantity that does not create any income or NRW. East Water applies the Surpervisory Control and Data Acquisition (SCADA) system in its water management to control water pumping and distribution from its 16 water stations, while simultaneously carrying out its maintenance plan. It is a Real Time monitoring system with a control center at the Rayong Operation Center. It potentially solves problems, reduces any mistakes from water pumping and distribution immediately, controls management cost and reduces manpower.

Importantly, it reduces Non-Performing Asset (NRW) effectively.

In 2016, East Water has carried out the project to reduce the Non-Performing Asset (NRW) in addition to the routine operational plan. This included the improvement of anti-rust system of BangpakongChonburi pipeline, hiring maintenance staff for emergency cases, formulating a plan and performing water meter calibration on both main and customer water meters and maintaining equipment in water pumping and distribution system. Leaks in Junction Wells were also fixed after long periods of usage.

Management of Non-Revenue Water East Water has measures to control the volume of Non-Revenue Water (NRW) in the entire system to be at the rate of ≤ 2.50. Since 2012 onwards, East Water has gradually control the lost water in the water supplying system well. The calculation on the Non-Revenue Water volume can be made from the equation as shown below.

because it was required to stop supplying water. As a result, the NRW in 2016 was higher than normal as shown in the picture below. At the end of 2016, the situation returned to normal. East Water fixed the leaks in the Junction Well and completed the repair in December. For the leaks in ChachoensaoBangpakong pipeline, the maintenance team found that it would take longer because the leaks are found in the middle of the pipeline and it is impossible to stop supplying water to the consumers. The maintenance can be performed after the water situation becomes better. It is expected to take place in 2017.

However, the NRW volume in 2016 was 2.76%, a significant increase compared to the previous year, as there are 2 leak points consisting of 1) Junction Well pond at the Booster Pump in Nong Pla Lai which is the water supplying system to the areas of Chonburi-Pluak Daeng-Bo Win and the 2) the Chachoengsao-Bangpakong pipeline. The leaking point is in the middle area of Khlong Bang Wua. However, the leaks could not be fixed immediately due to the drought in 2016, resulting in lower water cost. The maintenance was delayed to avoid any effects to customers in Chonburi and Chachoengsao

In terms of service quality, there are various factors such as pressure, the agreed water flow rate, and service standard to be considered in each area and each group of customers separately. Only the service area of Pluak Daeng - Bo Win has the problem of pressure. As East Water has expanded the pipeline network of Nong Pla Lai - Nong Kho Line No. 2 and the pressure has been increased in that pipeline to be able to supply the water in the long distance, some water users at the upstream of the pumping station are affected. Therefore, East Water has installed the Pressure Relief Valve at the water receiving station of the customers for the safety and quality standard in supplying water to the customers.

In terms of the efficiency of the pipeline system, East Water has a maintenance plan for water pipelines and corrosion protection systems to ensure continuation of water delivery, and also plans to deal with changes in the road plan due to urban expansion, which will affect the orientation of the Company’s original pipeline. In this case, the Company will have to reroute the pipeline and at the same time ensure that this causes as little impact as possible to water users.

East Water is continually committed to maintaining the reliability of water pumping and distribution systems. Targets have been set to prevent damages to machines and equipment which will lead to disruptions or closures in main water distribution pipelines. In addition, stopping water distribution for maintenance is set to be no longer than 8 hours. Class A machines which are of great importance must never stop functioning.

Possible Effects from Water Pumping Process As East Water’s business operation consists of pumping water from water sources which are only ground water sources in 3 three eastern provinces, including the area in Rayong consisting of Dok Krai Reservoir, Nong Pla Lai Reservoir, Prasae Reservoir, in Chonburi and Chachoengsao areas consisting of Bang Phra Reservoir, Nong Kho Reservoir, and private ponds including Bangpakong River and Samnak Bok reserved pond. The amount of water is indicated in the table of water usage by East Water in 2015-2016 on page 33.

The water sources are human-made reservoirs. A key factor affecting environmental changes of water sources is human activities. The human activities include deforestation at the watersheds which decreases the water level in the river, destroy plants and soil dams along banks, which creates changes to the waterways, contamination by pollutants that decreases the water’s quality, as well as improper use or overuse of water which endangers the water ecology.

East Water is an organization that consumes water, and since its main activity is the distribution of water, it can be guaranteed that the Company’s water pumping system is not contaminated. It is highly certified that East Water’s water pumping system is not contaminated by any waste. As for the changes in biological environment, the impacts created by East Water’s activities cannot be assessed

directly and clearly. This is because the water source is consumed by several sectors and all activities affect the changes in biological environment.

Nevertheless, East Water realizes the importance of water quality problem. East Water has continually supported activities to increase more green areas in forest conservation areas along the borders of 5 provinces, in which the Eastern watershed forest is located. The Company has also supported water quality assessment in Water Conservation Network Project. In 2016, East Water began to follow up parameter values of water quality from main water reservoirs. It was found that the parameter values of water quality were significantly changed. Therefore, East Water has formulated a plan to analyze the quality of water in the reservoirs managed by East Water in 2017 to uncover the root causes of the changes and seek guidelines or strategies to solve the problems. This will maintain water quality to meet the standards.

Bangpakong River, a natural water resource, may encounter river bank subsiding and erosion due to a rapid increase and decrease of water level and severity of water flow. Therefore, East Water, with the cooperation of the Engineering and Technology Department, The Asian Institute of Technology (AIT), investigated the effects of water pumping from

The Company pumps only in the rainy season because in normal conditions during the dry season Bangpakong river contains high salinity. However, when comparing the amount of water pumped by East Water with the river water amount in the rainy season, it is found that the water pumped is only 0.74% of the river water amount.

A study of the Division of Engineering, The Asian Institute of Technology (AIT) in 2009 to investigate the water flow in Bangpakong River Basin, using Mathematic Model to indicate the effects of water pumping undertook by East Water shows that, compared to non-pumping, the water level taken from the actual pumping rate by East Water’s pumping station in 2006 decreased by only 0.24 centimeters.

Compared to non-pumping, the water level occurring from the maximum water pumping rate (2.68 cubic meters/second) decreased by 0.88 centimeters.

Pumping water during water shortage period in 2001 shows that the water level decreased by only 1.65

centimeters, which barely affected the flow of water in Bangpakong River Basin as the volume of water pumped was little when compared to the water flow in the rivers. The volume of water pumped compared to average flow of water in the rivers at the water pumping station was only 0.6%. It can be summarized that water pumping carried out by East Water did not significantly affect subsiding banks above the water pumping station at Khlong Khuean Distirct, Chachoengsao and Kabinburi, Prachin Buri.

In past operations, East Water has abided by the rules set by Chachoengsao province in its water pumping activities, and ceased pumping, as notified

In pumping water from Bangpakong River, East Water has coordinated with related agencies such as Chachoengsao irrigation project, government sector of Chachoengsao, Bangpakong River water users, etc., in order to be able to manage the water in Bangpakong River with the water users in different sectors properly and effectively. Moreover, in 2016, East Water began the discussions with the Royal Irrigation Department to carry out the activities to promote knowledge and develop agricultural projects as well as promoting the efficient use of water management to the water users at the water pumping area of East Water, so that the community can have a better understanding of water management and can take advantage of Bangpakong River properly and effectively for sustainability. Such operational plan will begin in 2017.

Management and impact from the pipelining process of East Water Another important process of water management of East Water is the construction of pipelines and pumping stations. Typically, the pipes will be placed in the road line under the case of various

And local a authorities. As a result, the construction impacts communities in neighboring areas. Being aware of such issue, East Water has managed its construction projects in ways that minimize their impact on the construction area itself as well as on adjacent areas, by requiring the contractors to comply with safety standards of relevant authorities.

In 2016, 3 major construction projects have been launched, including Prasae Reservoir-Nong Pla Lai Reservoir Raw Water Pipeline Project, Nong Pla Lai-Nong Khor Raw Water Pipeline Route 2 Project in Rayong and Raw Water Pumping from Private Water Resources Project in Chonburi. In the case of the Prasae Reservoir-Nong Pla Lai Reservoir Raw Water Pipeline Project, pipelines need to be passed through community areas. Therefore, East Water employed the following strategies to prevent and reduce effects to road users and nearby communities close to the construction site.

Before the operation: East Water’s supervisors and contractors, along with local leaders, will engage in public relations activities to clarify the operation procedures, the consequences and prevention thereof to the people concerned.

During construction: In case that problems or complaints about the construction are raised, East Water will address the issues immediately. East Water provides complaint centers to receive

complaints through both online and offline channels.

This enables those who are affected from East Water’s construction to voice complaints quickly. To communicate among construction supervisors and contractors, an internal communication group is created. The group is participated by representatives of organizations or communities involved so that they may be notified of any problems promptly. A complaint procedure is shown in the picture below.

Complaint notification process for correction Process of answering the complaints to the appellant

In 2016, 4 communities that have been affected

by East Water’s construction projects sent their complaints via the complaint receiving center on the following issues: 1. Safety during the construction.

2. Inconvenience in transport When East Water was made aware of the problems, supervisors and relevant persons were immediately mobilized to monitor and urgently solve the problem. In addition, in order to prevent impacts from construction projects in the future, East Water has laid out the following guidelines: 1. Improve the scope of employment (TOR) of East Water’s construction projects with the duration for repairing and restoring the road conditions clearly identified, and setting the standard for recovering the road / area along the pipeline with approval from the local represetatives.

2. Make additional adjustments to the Standard Checklist to encompass a concrete plan for pollution prevention and reduction of impact from construction.

3. Have representatives of agencies in charge of permitting the construction of the pipeline in the area inspect and approve the restoration work of areas along the pipeline according to the standards of said agencies.

4. Arrange meetings with contractors and related agencies to acknowledge the detail of the project before starting the operation, and hold additional joint meetings during the operation to acknowledge problems and find solutions together, while also closely monitoring the operations on a weekly basis.

Energy management and reduction of greenhouse gas emission The environmental factors, the variability of the climate, and fluctuating seasons are the signs that indicate the problem of “Global warming” that is causing a huge impact on the world.It is undeniable that the problem is partly caused by human activities that increase green house gasses in the atmosphere, resulting in the rise of temperature on the earth’s surface. Although East Water does not use any type of gas in its operations and therefore does not release greenhouse gases, it does, however, use electricity in pumping water through its 16 pumping stations and a network of pipelines.

Therefore, East Water puts its efforts into implementing energy conservation projects continually by improving the water supply system, which is its core operation, and by fostering the maximum efficiency in management, as well as conserving energy as prescribed by law in areas covered by its operations as follows: 1. Five pumping stations registered as control factories, which are Nong Pla Lai Water Pumping Station, Dok Krai Water Pumping Station, Pressureincreasing Water Pumping Station, Bangpakong Water Pumping Station, and Chachoeng-sao Water Pumping Station.

2. One control building which is the main office building.

Evaluation results of the capacity to conserve energy in the preceding year are applied to the following year’s plan for reduction in energy consumption in the organization level, as well as the production, services and equipment levels, by taking into consideration the amount of energy loss and make improvements accordingly.

East Water has established a working group on energy management to regulate the policies for energy conservation as the guidelines for the implementation of energy conservation and to promote energy use for maximum efficiency and benefits. In 2016, the projects implemented to improve the efficiency of energy use are as follows: 1. Project to lower the water level from the high tank in order to balance the water level with the reserved water pond by installing pressure increasing water pumping sub-stations at the water station for users in Nikom Phattana Municipality, Rayong Central Prison, and Ban Khai Technical College.

2. Project to reduce the use of electricity in diverting water from Prasae Reservoir to Chonburi area by diverting the water to the Booster Pump to increase the pressure of water sent from Prasae Nong Pla Lai pipeline for deliver directly to the Chonburi area.

3. Project to install a Mobile Diesel Engine to increase the efficiency in pumping water from various water sources where electricity is not available, and to help save energy by using it only when the water is required to be pumped, so that there is sufficient water to meet users’ demands in the Chachoengsao and Chonburi areas, where water is purchased from private ponds which helps save 36,000 kWh of energy through this Standby system.

4. Energy conservation projects at controlling stations by changing the air-conditioners and electric light bulbs inside the water pumping station, which helped save 80,248 kWh of energy.

5. Project to study the use of water pressure to generate electricity with the Mini-Hydro Power system.

In 2017, there are plans for implementing the projects as follows: • Project to lower the water level from the high tank in order to balance the water level with the reserved water. This project can reduce energy use in the Rayong area equivalent to 8% of the monthly electricity cost in Rayong province.

• Project to install the Mirco-Hydro Power system to generate hydro electricity.

• Energy & Water Management System - Improving SCADA Graphic & DATA to monitor the energy consumption in water pumping efficiently.

Energy conservation is one of the policies that East Water focuses on and continues to enforce.

However, because East Water’s main operation is to pump water which consumes electricity, there is a direct correlation between East Water’s growth and turnover and the country’s economic growth.

This growth, in turn, has a direct impact on energy use and thus the increase of greenhouse gas emission.

At present, East Water has, to its full capacity,

undertaken projects to reduce energy consumption in its water pumping system, including the study of new technologies and innovations. However, there is currently no technology or innovation appropriate or worth investing in for East Water’s business operations. As a result, in the following year, this point may not be considered a key issue for the sustainability of the organization.

The data on electric power consumption of sub-meters for pipeline maintenance and 50 water metering station was not collected in 2016 because the data submitted by the Provincial Waterworks Authority to East Water was not clear. However, East Water will collect the complete data and include it in next year’s report.

SUSTAINABILITY REPORT 2016

East Water’s electricity consumption calculated by operational control in 2016 was equal to carbon dioxide emission at 83,373 tons. This figure was calculated from the electricity consumption of the 16 main water pumping stations of East Water and the head office. The electricity consumption increased considerably compared to 2015. In 2016, electricity cost at Prasae water pumping station will be equally shared between East Water and the Provincial Water Works Authority (PWA) as stated in the MOU, differing from year 2015 when East Water paid for electricity

Sustainable Business Growth (EC2)

Measures to serve the climatic variation and business opportunities.

The problem of global warming and drought is rapidly expanding and causing many areas in Thailand to suffer from a shortage of drinking water and water for consumption. Unless a plan for water management is put into place, there is a concern that there will be a severe water shortage for domestic use and industrial use, which may result in a water war in the future.

East Water has always been aware of this issue because it directly affects water management and increases operational costs. The cost of water per unit in 2016 was 0.40 baht, or 10% higher than that in 2015, because applying water shortage preventive measures requires close monitoring and surveillance of rain water each year. This information is useful in formulating a plan for diverting water from various water sources, and in developing cost water sources to meet increasing demands.

With its potential and business opportunities, East Water has set the direction for business growth in the long term to ensure sustainability , by further developing its untreated and treated water business with the idea of encouraging industrial operators to be able to access comprehensive water management, which includes: • Producing industrial water with the right quality that can allow the operators to use water adequately without wastage of untreated water • Providing industrial wastewater treatment that yields water suitable for reuse as prescribed by law. This can reduce the cost of buying water for industrial operators and allow a more appreciative use of water resources, while lessening the impact on the environment.

In 2016, East Water provided a water service proposal to offer a full range of water services to many industrial operators. The number of proposals made the industrial water amount, and the treatment of wastewater for reuse can be summarized as follows.

Direction of East Water’s sustainable growth

SUSTAINABILITY REPORT 2016

Nevertheless, the operations mentioned above are simply short and medium term plans for water management to cope with the climate variability. In the long term, East Water sees several key factors that point towards an opportunity for business growth, namely, the environmental friendly trend in business operations, the increase in the statistics of annual wastewater discharge, and most importantly, the government’s plans to stimulate the economy by pushing forward the Eastern Economics Corridor Development plan (EEC). This will encourage investments in the Eastern region covering the areas in Chachoengsao, Chonburi, and Rayong, which will propel it into a strategic industrial area in the long run.

The fact that this region already has a competitive edge in that it contains East Water’s network of pipelines covering an area of 491.8 km. only serves to strengthen its position.

The customer satisfaction toward East Water service was defined at “Highly Satisfied” with the average of 4.34, higher than the customer satisfaction in 2014.

However, East Water and relevant persons are very aware of maintaining the level of satisfaction together, while focusing on improving the service by prescribing the following measures: • Management of the drought situation The responsible persons will determine the means in finding reserved water sources and find ways to enable the pumping system to operate at maximum capacity, while also continuing to periodically report on the water situation and status quo of various projects to East Water’s executives for acknowledgement and consideration.

• Management of the water quality in private ponds East Water stipulates the measures to require relevant persons to implement the quality improve ment according to the established criteria without delay. If the operation cannot be performed, the water from such sources will be cancelled.

As for other water resources, East Water has been monitoring the parameters for water analysis at main water reservoirs and finding significant changes in water quality. The Company comprehends the gravity of these changes and has, as a result, supported a water assessment program titled East Water Network for Water Conservation. In addition, the Company has joined hands with the

Forest Conservation Foundation to continuously plant trees along the borders of 5 provinces, which are important watersheds for the Eastern region. In 2016, East Water was able to increase more green areas and maintain the balance of the ecology system on over 303.5 rai of land.

Nevertheless, East Water formulated a plan to analyze the water quality of main water reservoirs managed by East Water in 2016 to uncover the root causes of the changes and seek guidelines or strategies to solve the problems. These will maintain the water quality to meet the standards and enable water users to pump water for consumption according to plan, as well as allowing living creatures, aquatic animals and plants to thrive.

Complaints and Solutions Statistical data of complaints from 20132015 show that 80% of complaints are about the quality of raw water.

To address these complaints, the Company will specify the types of complaints and the services requested in order to assign the team responsible for analyzing, providing solutions and preventions within a specific timeframe. This follows the internal control system in solving and preventing complaints. Assessment of customer satisfaction after the complaint has been dealt with is required every time. Also, a monthly report must be presented to executives in order to constantly improve the efficiency of the troubleshooting process.
