The capacity development program in Naivasha aims to improve the provision of water and sanitation services to all residents of Naivasha municipality (165,000 women, men and children) with a particular focus on sustainability of services, customer satisfaction and improved access for the (peri-) urban poor. So, the coming in for VEI with the proposal of establishing WOP type of partnership with Naivasha came in an appropriate time. In Naivasha, water service is provided by Naivasha Water & Sanitation Company (NAIVAWASS). The idea of the creation of the partnership project between VEI & NAIVAWASS came from the Embassy of the Kingdom of the Netherlands (EKN) in Nairobi, Kenya, which was already working and funding the "One Naivasha for All Programme", the program of Wildlife Fund East Africa. Thus, this WOP is proposed as one of the management improvement plans of above mentioned program.
