Foreword

Bavarian Institutional Water Cooperation

The Government of Kenya is committed to ensuring the progressive realization of the human right to water, and reasonable standards of sanitation through taking steps to protect, respect and fulfil these rights, as required by the Constitution. The National Water Policy 2019 has prioritised education, training, technology, research and innovation; affirmative action; gender mainstreaming; taking action to mainstream climate actions in the water sector; as well as institutional arrangements, including devolved mandates.

The provision of quality education and training is fundamental to the Government’s overall strategy for social eco-

nomic development. Quality education and training will contribute to achievement of Kenya’s development blue print and sustainable development goals.

The Bavarian Institutional Water Cooperation (BIWAC) through its Kenyan partners: Kenya Water Institute (KEWI) and Water Services Providers Association (WASPA) have developed a course and its training manual on Water Supply and Waste Water Treatment and Management targeting capacity building of artisans working in the water sector in Kenya.

This Manual covers three main areas, namely: basic water, water resources and their characteristics, and types and characteristics of waste water. At the end of the module, participants are expected to have basic competencies and perform their duties and tasks effectively.

It is my conviction that this course will play a great role towards development of competent human resource for the Water Supply Waste Water Treatment and Management and the entire water and sanitation sector’s growth for sustainable development.

Foreword

I am pleased to welcome this noble and timely programme in the water sector that is aimed at equipping our water professionals with requisite technical and vocational training. Technical and vocational training is in line with the government’s commitment to promote Technical and Vocational Training in Kenya. Technical and Vocational Education and Training (TVET) constitutes the form of education, training and learning activity leading to the acquisition of practical knowledge, understanding and skills relevant for gainful economic engagement, both formal and informal.

As other sectors continue to implement TVET, we in the water and sanitation sector cannot be left behind. Water and sanitation are key enablers of the governments vision to realize the Big Four Agenda. And as technology evolves, water crisis rises and the need for immediate solutions to solve sanitation challenges, so does the need to have competent operators of the water and sanitation systems.

Bavarian Institutional Water Cooperation

In this vein, WASPA in close collaboration with Kenya Water Institute and supported by the Bavaria State Chancery under the Bavarian Institute of Water Cooperation -BIWAC programme that started in 2017. With several years of water management, Bavaria State provides us with requisite technical and knowledge background that we need to formulate our local training programmes. It is to be recalled that practical competence-based education is the direction that our education system has adopted. In this way, trainees will be required to undergo a theoretical classroom-based training as well as practical learning sessions in the specific areas of operations based on their particular career interests.

Also included in this programme are experts ground water management. Members of Kenya Water Industry Association will also provide essential learning environment for the drilling and other emerging technologies. So far 35 certified trainers of trainers have undergone a rigorous training with both classroom and in the field, training anticipated to commence in March 2020. Among the topics that are earmarked at the kick off include; basic water supply, -water resources and their characteristics, types and characteristics of waste water. We are grateful that Kenya Water Institute will take the lead role in coordinating the roll out of the curriculum. Moreover, both Nairobi and Kisumu Water and Sanitation Companies will also provide the infield training facilities.

It is our anticipation that from this programme we shall streamline vocational training in the water and sanitation sector. Moreover, the quality of our operators will be greatly improved. Not only will this programme attract more interest as a career path but it will also enable more women professionals to join the sector. WASPA will continue to be at the forefront of promoting capacity development, setting standards as informed by the international best practice and thereby ensure enhanced service delivery.
