SPATEX 2013: the show that pools your resources A great leisure project is only as good as the sum of its parts and for it to come to successful fruition, it requires the blending of many disciplines and talents. Entities involved in building or refurbishing a pool or a leisure complex are not limited to that of only the specialist swimming pool contractors. These projects need precise design and planning - architects are as vital as the person who digs the hole. In any commercial leisure application, specifiers have to know exactly which piece of equipment is right for each installation. Electrics, brickwork, plastering, tiling, water treatment and plant; these are the inner workings of what makes a successful leisure project. Which is where SPATEX 2013 comes into play. At the annual exhibition for the wet leisure industry, now in its 17th year, you will find the majority of the UK and European suppliers/manufacturers of swimming pool products and hot tubs conveniently situated under one roof. But the exhibition is also a broad church, encompassing and appealing, as it does, to the disciplines of architects, specifiers, private and commercial leisure operators, local authorities and project managers. There truly is something for everyone who works within the leisure environment. Take for instance, the dedicated Commercial Information Centre, providing free and impartial advice. Leading industry figures will be on hand to provide up-tothe-minute information, covering a diverse range of subjects from chemical water treatment, through to Heating & Ventilation and on to design and refurbishment. SPATEX 2013 is also an unparalleled showcase for new innovative products for the coming season. Swimming pool heat retention covers, heat pumps, water circulation pumps, chemical dosing systems and, most importantly, energy are just some of the products that you can expect to see on display. Advances in these areas are being made all the time. More than 50 ground-breaking new products were showcased at SPATEX 2012 including many money saving and eco friendly options such as solar systems, automatic commercial dosing, disabled lifts and transporters, stunning steam rooms and beautiful state-of-the-art pool finishes. Big industry names such as Certikin and Calorex regard SPATEX as their one annual launch pad for new innovative products.

It is, however, far more than just an exhibition. This is a show that educates. The Institute of Swimming Pool Engineers works alongside SPATEX to provide interesting and highly informative training workshops. Once again, they have organised a series of seminars by industry figureheads who are first in their field of expertise. And what a lot there is to talk about with green issues and, in particular,

renewable technology, being at the forefront of the consumer’s mind. Conservation will be a major theme for SPATEX 2013 and in particular, ways to conserve energy, water and money, in both the domestic and commercial areas of the industry. SPATEX Organiser Michele Bridle says: “If you are on a busy schedule there is

nowhere in the UK where so much can be seen in such a short space of time. For architects, specifiers and designers, SPATEX 2013 offers the latest in technological design and innovation for the commercial and domestic wet leisure industry. It’s often been said that if what you are looking for is not at SPATEX you probably don’t need it!”

With free admission, discounted parking and taxi fares from Brighton station to the venue reimbursed (on presentation of a receipt), on-site accommodation and the backdrop of all that cosmopolitan Brighton has to offer, SPATEX is as fun as it is informative.

Held at the Hilton Brighton Metropole Exhibition Centre, SPATEX 2013 is running from Sunday February 3rd to Tuesday February 5th.

BISHTA British and Irish Spa and Hot Tub Association


BISHTA – the British and Irish Spa and Hot Tub Association was established in 2001 to ensure that companies engaged in the display and sale of spas and hot tubs are properly trained in water hygiene management and understand the importance of maintaining these standards throughout the product life. Those companies who satisfy BISHTA’s entry requirements are able to apply

for membership and if approved become a member of the Association. BISHTA is recognised by the HSE (Health and Safety Executive) and the HPA (Health Protection Agency). It has a renowned team of experts on hand to offer support and assist with issues, or questions. As BISHTA members are given industry standards to follow in spa and hot tub safety

and are expected to uphold ethical trading practices, this should enable smooth working relationships to develop with architects and other professionals when installing spas and hot tubs. Training in water hygiene management issues is a prerequisite to joining BISHTA, ensuring the risks are assessed to prevent breakouts of diseases, such as legionnaires disease.

Howard Gosling, BISHTA’s Technical Advisor runs regular water hygiene management courses for both BISHTA members and also non-member companies who wish to learn this important information. Spas and hot tubs can be used in domestic settings and also in business settings, such as the growing popularity of having them in holiday accommodation. However, please note that these business settings should only be used when the equivalent of one family has access to the spa or hot tub. In situations where the equipment is shared amongst a number of different users, then a commercial spa is required to enable the equipment to

be used safely and appropriately. The benefits of dealing with a BISHTA Member are: • Purchasing quality products that conform to European standards • Members that abide by a code of ethics to promote fair and responsible trading • Knowledgeable staff who have access to an expert technical advice service, if needed • Training for members in water treatment • Training also in the handling and transport of chemicals to comply with dangerous goods legislation and registration with the Association's own Dangerous Goods Safety Adviser

• Clear warranties in case of any issues • A thorough after sales service • Public Liability Insurance Cover Similar to SPATA, BISHTA has its own annual awards and this year’s BISHTA Awards will be the sixth such event, now co-located with the SPATA (Swimming Pool and Allied Trade Association) Awards. Members will be competing in a number of categories for hot tubs and swim spas. For more information on BISHTA and its members, visit or call 01264 356211.


BSPF British Swimming Pool Federation


The British Swimming Pool Federation (BSPF) has been set up to bring together various UK bodies to strengthen the voice of the wet leisure industry. These UK bodies represent contractors, manufacturers, distributors and retailers of swimming pools, spas, saunas, steam rooms and associated equipment, along with other like-minded organisations.

BSPF works on behalf of: • The Swimming Pool and Allied Trades Association (SPATA) • The British and Irish Spa and Hot Tub Association (BISHTA) • SPATEX • Pool Industry Promotion (PIP) STA is the world’s largest independent

swimming teaching and lifesaving organisation, and delivers the highest quality training across four key business areas – swimming teaching, lifesaving, first aid and leisure management. STA is internationally recognised and is uniquely positioned as the only awarding organisation in the UK that can deliver multi-

aquatic programmes – swimming teaching, lifesaving and pool plant qualifications - that are approved by Ofqual, accredited by SQA and the Register of Aquatic Professionals (RAPs) – the new single qualifications framework structure that has been launched by SkillsActive. Importantly, STA is committed to representing the needs of the leisure industry and sits on all the major UK committees concerned with promoting water safety and swimming. This includes working in close partnership with BSPF, who STA has developed a strong alliance with over the years.

As industry leaders, STA and BSPF have a shared mission to improve standards. By working together they use their joint strength to further their aims of increasing the number of quality swimming facilities available and creating more opportunities for people to swim. STA is also represented on the BSPF board. SPATEX is the annual trade exhibition and is a focal point for the industry to find out about new products and services, as well as the vital social networking opportunities that are created in this unique location. SPATEX works in partnership with the Institute of Swimming Pool Engineers (ISPE) to run an excellent

education programme with a wide range of workshops on relevant topics. This February will see the 17th annual show held at the Hilton Brighton Metropole Exhibition Centre and it promises to be another vital contribution to the industry calendar. Pool Industry Promotion (PIP) handles all of the publicity and public relations for the industry relating to both consumers and the trade. BSPF is dedicated to building alliances with other organisations to promote the wet leisure industry.

Rehabilitation Hospital, to full-sized competition pools. This growth in popularity has been largely due to UV's reliability and ease of use. Another major factor is the reduced reliance on traditional chemical treatments it affords, particularly chlorine. UV is also highly effective at destroying chlorineresistant microorganisms like Cryptosporidium and Giardia. Based in the United Kingdom, with offices in China and a worldwide distributor network, Hanovia is a world leader in UV disinfection technology for industrial applications. The Company has over 85 years of experience in the design, development, manufacture and distribution of UV systems worldwide. For more information please visit the Company's website.

Hanovia’s SwimLine™ UV System for professional pool quality Hanovia UV technology guarantees reliable and efficient chloramine removal and disinfection technology is included as standard, and allows facilities to cut power consumption by limiting operation to only what is needed to maintain the required de-chloramination level. The system’s controller provides continuous UV monitoring to alert for low UV, power failures or other changes. The Hanovia UVLux™ broad spectrum UV lamps used in the SwimLine range feature the latest technology in medium pressure lamps and optimal efficiency. The system also incorporates an automatic quartz sleeve wiping system that reduces maintenance and extends lamp life. Hanovia’s SwimLine™ UV range provides safe and efficient removal of chloramines from pool water, while also acting as a disinfectant and providing you with standards the professionals demand in swimming. The SwimLine also incurs lower capital and operating costs than comparable UV systems.

The compact SwimLine is available in a range of U-shape, S-shape and In-Line configurations for easy installation in new-builds or incorporation into existing water treatment systems.


Water passing through the system is exposed to UV light, which destroys chloramines, the harmful by- product of chlorine disinfection, responsible for strong odours, skin and eye irritation as well as damage to pool equipment. UV light also inactivates microorganisms on a cellular level and, when coupled with chlorine treatment, the SwimLine provides a highly effective second barrier against infection by chlorine-resistant microorganisms such as cryptosporidium.

Hanovia’s UV systems are already widely used in pools and spas around the globe, from the UK to Australia. One of the most prominent UK installations is Nirvana Spa in Berkshire. Widely regarded as one of the UK’s most prestigious spa facilities, Nirvana has nine pools, each filled with pure spring water drawn from over 200 metres beneath the ground. Each pool is treated with a Hanovia UV system, including the “Celestial” floatation pool, the UK’s largest hydrotherapy pool containing salt imported from Israel’s Dead Sea.

The SwimLine contains features designed to reduce operating costs by eliminating wasted power and materials. Power Stepping™

Another celebrated UK installation is the Riverside Leisure Centre in Exeter, the first leisure centre in the UK to install a UV system.

That was back in 1994, when the centre had just undergone a complete refurbishment and a Hanovia UV system was chosen to replace ozone. The Hanovia system performed so well for the subsequent 16 years that when the time came for an upgrade in 2010, the centre didn’t think twice about replacing it with another Hanovia system. Other users of Hanovia’s UV system include global five star hotel chains, private schools and a number of English Premiership football clubs, including 2012 European Champions.

About Hanovia Based in the United Kingdom, with a worldwide distributor network, Hanovia has been pioneering swimming pool and spa water UV treatment technology for over 20 years. It is also a world leader in UV disinfection technology for many applications in the leisure, food, beverage, pharmaceutical, electronics, aquaculture and marine industries.

HPA condensation in swimming pools Hidden Dangers: Cutting corners on condensation in public swimming pools could spell disaster‌. Swimming pool environments have changed significantly in recent years, most markedly in leisure pools. Higher water temperatures combined with an increase in the number of bathers has led to higher levels of chemical disinfection. Chlorine-based disinfectants are the norm, which together with contaminants introduced by bathers, produce chloramines. These are thought to be the most important factor in the corrosion of stainless steel in a swimming pool environment. The temperature of the air in pool halls is generally held about one degree centigrade above water temperature. High air temperatures significantly accelerate corrosion. Atmospheric moisture in pool buildings comes from the evaporation of pool water and as droplets from the turbulent water features that have become increasingly common in leisure pools.

Higher levels of humidity can lead to condensation in cooler parts of the building and during the cool of the night. Consequently the atmosphere of indoor swimming pools is one of the most aggressive to be found in a building environment. Under the specific temperature conditions near the ceiling, chlorine containing chemical species in vapours from the pool water can condense onto the stainless steel components and dry out. As this can be a repeated cycle, very aggressive concentrations of chlorinecontaining species may build up. High humidity is the result of evaporation of water into the air that is greatly increased by larger pool surface areas with heavy bathing loads like that at the transvaal. Other factors that will increase water evaporation include increased pool water temperature and lowered space temperature. Environmental control systems can prevent the build-up of humidity by controlling the

amount of moisture in the air and therefore controlling condensation. A typical leisure centre pool can contain up to a million litres of water heated to around 30 degrees centigrade. Water evaporates from the surface at a rate of hundreds of litres every hour. Evaporated water needs to be removed or it will turn to condensation that will immediately start to cause problems. Before heat pumps, that valuable energy would have just been expelled to the outside atmosphere. Heat pumps cleverly provide the means of recovering that energy. Air is passed through the evaporator, a finned coil, where it is continuously cooled. The water vapour is condensed to give up its latent heat and runs away as water. At normal pool temperatures, 2 kWh of latent heat is recovered for every three litres of water vapour condensed. The air temperature has been lowered by the removal of sensible heat to enable the


Prior to the installation of a Calorex HRD30 air handling unit, the pool hall at South Moorlands Leisure Centre was plagued with condensation and damp problems, resulting in rotting windows and doors as well as unpleasant conditions for both swimmers and leisure centre staff. The Calorex HRD30 typically offers 300% heat recovery to pool water and/or pool hall air compared to just 50-60% from recuperator type air handling units. Typically, the unit is capable of removing 300 litres of water in a 24-hour cycle – and plays a vital role in maintaining temperatures and conditions for indoor pool environments.

A pair of identical Calorex HRD25 air-handling units work in tandem to maintain perfect atmospheric conditions offering heat recovery to either the pool water or the pool hall air system depending upon demand at the Willowburn Sports Centre at Alnwick in Northumberland. Two pools operate at different water temperatures i.e. main pool at approx. +28 deg centigrade and teaching pool at approx. +30 degrees centigrade. Pool hall air temperature is maintained at a minimum of +1 degree centigrade above the pool water temperature, providing an air change rate of around six per hour in the pool hall, introducing high volumes of fresh air via the plant and controlling humidity levels within a band of 55% to 65% RH.

use of coatings, treatments and plastics. When the overall costs of using a heat-pump are considered, it is important to remember that heat pump dehumidifiers will recover sensible and latent heat that will be returned back into the pool water giving an efficiency of 300 – 350%. Passive units cannot do this, offering only 50 – 60% when external air temperatures are favourable. Cutting corners can only be a false economy that can cost lives when it comes to providing safe public amenities such as large indoor swimming pools. The implications of inadequate dehumidification methods at leisure centres, community pools, health clubs and hotels can result in structural failures with potentially devastating effects. As it has been witnessed on far too many occasions, much more than just a question of poor housekeeping, the consequences of inadequate control of humidity in swimming pools can be catastrophic.

Calorex Delta machines offered a slim-line solution to eliminate condensation at the Torridge Pool in South Devon. Not only could the compact machines be manoeuvred into the cramped plant room, the punchy units also offered outstanding energy efficiency as they work as a combined heat pump dehumidifier with automatic heat recovery. . Richard Carrington is Managing Director of Calorex, a member company of the HPA.


dehumidification process to proceed and both the sensible and latent energy come together in the refrigerant gas. This is now raised to a higher temperature by the compressor and used to heat the pool water as well as the pool air. When the humidity rises above the target level, a compressor is switched on, together with the integral heat pump circuit and the heat recovery dehumidification process starts. Latent and sensible energy available in the moist air is recovered and returned to the pool water and air via the built-in heat exchangers. If the recovered energy is insufficient to meet the water and/or air heating load, the unit’s integral low pressure hot water heat exchangers redress the balance. As an added bonus, the system cleverly takes care of the pool environment by incorporating automatic fresh air control. Introduction of fresh air that also passes through the heat recovery process at up to 70% of recirculated air is kept to a minimum to satisfy occupancy and dilution demands, reducing to virtually zero during unoccupied periods. Should natural solar gain increase the air temperature of the pool hall, the units can even provide air conditioning by dissipating unwanted heat into the exhaust air. Systems for wet leisure environments are specialist because they need to be designed to tolerate the harsh environment of a pool hall and its associated water treatment chemicals, such as chlorine. All components have to be specially selected resulting in extensive

Ultraviolet Disinfection & The Model Aquatic Health Code

Although many aspects of the design and construction of aquatic facilities are governed by regulation, other aspects are based on custom and practice based on many years of experience.

The MAHC code considered many aspects of UV disinfection and focused on the following key performance areas for application to swimming pools.

In order to address this situation in the USA, the CDC (Centre for disease control) implemented the Model Aquatic Health Code (MAHC). The MAHC Code, through a Steering committee and a number of technical committees, has brought together a large group of experienced industry professionals in many diverse technologies. Wherever possible, the language in the MAHC code has been based on peer reviewed science, data, and, as a last resort, custom and practice. The MAHC has been in development since 2005 and finally many of the various modules are available for public review.

Type of Facility As aquatic facilities with high bather loads of younger children are both more likely to result in outbreaks and to have occupants more susceptible to cryptosporidium, the MAHC code requires that certain facilities meeting this criteria must include a method to kill or remove cryptosporidium quickly from the water. UV disinfection is one of the techniques that is accepted as having the required level of science to prove its performance.

Turnover rate Although a standard developed for use in the USA, the collation and use of the latest science is expected to create a document that many aquatic facility regulators around the world will utilise as a reference for their own local regulations. One of the areas of the MAHC code is the application of UV disinfection, particularly for the control of cryptosporidium.

Ultraviolet Disinfection treatment Ultraviolet disinfection is now an established method of water treatment for municipal pools, and has become the preferred treatment choice for a number leading international leisure brands and new- build or renovated swimming pools. UV systems have a dual function in aquatic facilities. Firstly, they are able to destroy chloramines. Chloramines are formed when free chlorine reacts with organics such as sweat, body fats and urea, brought into the pool environment by bathers. Trichloramines in particular are powerful irritants which are responsible for ‘burning red eyes’, itchy skin, respiratory complaints and the often over powering chlorine smell associated with indoor pools. Additionally chloramines are also the cause of corrosive condensation, which leads to the damage of pool buildings and structures such as ventilation ducts. Secondly, they are able to provide disinfection of chlorine resistant micro-organisms such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional Chlorine disinfection. It is this second benefit that is most significantly addressed in the MAHC. A number of Cryptosporidium outbreaks in aquatic facilities in the USA, from New York to Utah, has created considerable interest in the best practice method to apply this technology.

As any UV disinfection system is a physical not a chemical process, the performance depends on ensuring that all the water in the pool passes through the system in a reasonable amount of time. The MAHC technical committee utilised exponential decay models and additional CFD (computational fluid dynamics) models to determine the turnover rate and also the disinfection rate required to achieve a less than 1/100ml concentration of cryptosporidium within a few hours. The simplest method to achieve this is to ensure that the filtration flow passes through the UV without any form of bypass or slip stream. Due to the requirement to add disinfection techniques to a wide range of indoor and outdoor aquatic facilities, a mathematical equation is referenced in the code and the flow-rate through the systems must be equal to or exceed this value.

Disinfection rate The turnover rate needs to be combined with a disinfection rate in order to ensure speedy removal. The MAHC code requires a 3-log reduction of Cryptosporidium in EACH pass through the treatment system. A 3-log reduction is a 99.9% removal. This value is selected as the best compromise between treatment level and benefit. Higher reductions than 3-log provided only marginal benefits in speed of reduction from any outbreak in the facility.

Validation of performance Under the MAHC code it is not acceptable to utilise manufacturers claims as to performance. This is essential due to the difficulty for regulators to verify these claims, and the exagerations that have plagued this market in the past. In order to be accepted as having a ‘proven’ cryptosporidium performance, any system must have undergone third party validation to an approved international UV




Effective against Chlorine resistent Cryptosporidium Reduces ‘Red Eye’ & Skin Irratations performance standard. In the case of the MAHC code these are the USEPA, the DVGW (German) and the Onorm (Austrian).

Standard of the equipment As expected, the MAHC code also addresses certain basic construction and manufacturing quality issues. As many of the states in the USA require the application of the NSF-50 standard, with its specific performance requirements and regular third party quality audits, the MAHC code incorporates the NSF-50 standard into the code language.

Breaks Down & Eliminates Problem Chloramines Allows Reduced Levels of Chlorine Provides Bright Sparkling Water & Fresh Clean Air

The MAHC code and its UV specification provides an excellent scientifically based standard to provide the best method of control in swimming pools for chemically resistant pathogens. It is not possible to immediately remove such pathogens but the MAHC code provides a scientifically based risk management approach with appropriate quality controls and transparency for manufacturers. As such, this can represent a best practice risk management tool for any aquatic facility managers.

UV Systems With the Model Aquatic Health Code offering increased value for swimming pool operators in the form of guaranteed performance and reliability, a number of manufacturers such as atg UV Technology in the UK, and ETS in the USA are now standardising their swimming pool UV systems to be fully compliant with the MAHC regulation, alongside offering pre-selected options tailored to the specific requirements of swimming pool operators. Typical swimming pool UV units should include; 316L stainless steel chambers, UV monitoring, automatic wiper systems, strainer baskets and the option for half to full power for energy savings during periods of no/low use. There are typically two types of UV systems available; traditional axial UV systems with inlets and outlets at either end of the chamber that offer swimming pool operators increased flexibility for retrofits or replacement of existing UV systems. For new modern facilities or where restricted plant room space is an issue, ultra efficient in-line UV systems are favoured. In-line UV systems can be installed directly into the pipe work and offer a much smaller foot print and increased efficiency and performance.

ISPE The Institute of Swimming Pool Engineers The Institute of Swimming Pool Engineers was set up in 1978 to establish an organisation for the individual swimming pool engineer (no corporate membership) to: • foster a professional approach to the design, installation and maintenance of swimming pools, enclosures and all ancillary equipment • give recognition to technical skill and ability • engage in the education and training of persons within all sectors of the swimming pool industry • promote unrestricted co-operation and liaison between all persons actively involved in the industry and its allied professions and trades • provide opportunities for association and interchange of thought and experience amongst the members and their colleagues Objectives ISPE's objectives together with the Institute's main function in the field of education and training, are achieved by means of: • One-day seminars • Hands-on workshops • Technical publications • Level one home study course • The Institute's own quarterly magazine. There are two completely separate routes to obtaining membership of the Institute: Either, application for membership for direct admission based on age and experience within the swimming pool industry, or student registration via the ISPE Home Study Course and examination to qualified technician.


Membership There are various categories of membership, enabling individuals of all ages and from all

sectors of the industry, and associated periphery trades and professions, to join. All applications are placed before the Council of Management on a regular basis, at which time each individual's request for membership is considered. Student Membership The Institute's home study course has been designed to allow a large degree of flexibility in study methods. This allows all students to progress at their own speed without having to keep up with anyone else, thus catering for every individual's particular situation. People may register at any time and may take the examinations when they feel ready to do so and not within any given period of time. Examinations are held annually in March. Mock examination questions are sent to all students each December for students to practice with, or to retain as a study guide. The home study course consists of four sets of study notes covering filtration, chemicals, construction and heating. Each subject is divided into sections, and at the end of each section there are questions relating to that particular section. Having studied each section, the student then attempts the questions, without referring to the study notes, and then checks back to ascertain whether their answers were correct.

SPATA The Swimming Pool and Allied Trades Association


The Swimming Pool and Allied Trades Association (SPATA) was set up to ensure that companies engaged in the construction of swimming pools and their suppliers, work to industry standards, which have been evolved over the years by experienced professionals. Today, SPATA continues to safeguard those principles of professionalism and good practice through materials such as the SPATA standards, which all members are required to work to. These standards can be purchased by professionals, such as

architects and local authority representatives, but please note builders must join SPATA to benefit from this information. A code of ethics promotes fair and responsible trading and with the support of the SPATA Technical Advisors, a group of experts in the swimming pool trade, members can access information and advice, where required. This advice is available for both commercial and domestic projects and many SPATA members deal with both of these areas.

Every day, pool owners and people looking for someone to build their new pool, or refurbish their existing one, visit the SPATA website, or contact the SPATA office to find competent designers, installers, engineers and ancillary suppliers in their area. They know they can feel more confident about choosing a SPATA member, as they are Trade Association members. SPATA is the voice which represents the swimming pool industry at home and abroad continued page 24 >

UK Pool & Spa Expo

The new and largest exhibition for the UK Wet Leisure Industry.

This exciting event running from 24th – 26th January 2013 at Birmingham’s NEC is a perfect platform for installers, architectural design practices, construction companies, council offices, leisure trusts or Health & Education Authorities to see a wide range of products and services from UK and international companies serving the wet leisure industry.

With a host of new product launches, demonstrations, cost saving measures, giveaways and a host of trade professionals waiting to engage in professional conversations, this event is one not to miss. UK Pool & Spa Expo are paying for you to park at The NEC - New Events, the organiser of this event,

announced this month that they will be paying for parking for ALL Visitors attending UK Pool & Spa Expo 2013. This represents a saving of £10 per day for all attendees and this offer, together with the ease of access to the NEC through its ideal location, should make UK Pool & Spa Expo 2013 the most accessible event ever in the UK wet leisure industry market.

Upon entrance to the grounds of the NEC, clearly marked road signage will direct drivers to a dedicated car park for visitors to UK Pool & Spa Expo 2013 located very close to the Hall. There is no waiting for tickets or refunds once in the hall either, just simple no hassle free parking for all attendees. This event will offer visitors a wealth of knowledge and will be a productive use of your time, in addition to all of the other great reasons the organisers are also working with UKTI, who have confirmed they will be supporting a B2B brokerage zone at UK Pool & Spa Expo. This is truly a “first” for the UK wet leisure industry as UKTI have never supported a UK event within this sector and in this format previously. Through the UKTI network of overseas offices and through the global marketing campaign of the exhibition, an initiative is being produced to encourage overseas buyers & distributors to attend UK Pool & Spa Expo 2013. UKTI will be creating a dedicated B2B area on the show floor where pre-arranged meetings between the International attendees and the UK industry will be coordinated. In addition to the significant investment by UKTI in creating this area and the marketing initiatives to encourage key

industry individuals to attend, the organisers are also offering a cash incentive for a group of 50 pre-selected buyers to attend UK Pool & Spa Expo 2013. NEW Events will contribute to the cost of travel & accommodation to pre-selected industry individuals.

and with situations such as this year’s drought restriction, SPATA led the way in discussing the issues with the relevant water companies to find a way forward. SPATA members have worked on some of the country’s most prestigious pools and showcased their work on popular television shows. SPATA members regularly work with architects to ensure they are aware of the SPATA standards to help ensure pools are constructed correctly. For domestic pools, SPATA members are part

of the SpataShield scheme and this means that customers should be able to access a Bond certificate for peace of mind during the build phase of a new project, subject to the terms and condition of the scheme. A number of members also have expertise in commercial projects and SPATA holds a Commercial Contractors register that can be requested by contacting the SPATA office on 01264 356210 or Every year, the SPATA (and BISHTA -British and Irish Spa and Hot Tub Association)
