The project aims to establish a sustainable water supply network for three villages and thus ensuring clean drinking water for approximately 420 families. For this purpose, the Danish NGO, Jysk landsbyudvikling i Nepal, received funds from The Grundfos Foundation in 2019. The project will be executed through the local partner organization of Jysk landsbyudvikling i Nepal and in close collaboration with the local government.

The water supply network must have the sufficient capacity to supply 65 liters of clean water per capita per day, as per Nepalese standard guidelines. The project is expected to eliminate the drinking water scarcity of the area. The project supports the UN’s Sustainable Development Goals and particularly goal 6: ‘Clean water and sanitation’ and goal 17: ‘Partnerships for the goals’.

Efficient and Sustainable Drinking Water Project

EnviDan is a consulting partner of the project and performs all the technical works, such as design, project management, and quality control. It is EnviDan’s responsibility to bring Danish expertise into the choice of design of the water supply system. Different possible water supply system solutions were analyzed. A simple and yet efficient solution was chosen based on the available resources and technologies. The focus is laid on delivering a sustainable water supply system.

A hydraulic simulation was performed for the sizing of the water supply distribution system. Solar power will be the primary power source to operate the submersible pump to lift water from the deep aquifer to an elevated 

storage tank with a capacity of 285 m3. The distribution from the overhead water tank will be based on gravitational flow. The selection of solar powered pumps and gravity-based water flow ensures lower operational cost and comparatively lower water tariffs.

It is crucial for the success of the project that the locals can operate and maintain the system themselves. Therefore, local technicians will be trained as part of the project so they can provide technical services during the operation and maintenance phase.

The project plans to support and establish an efficient framework for operation, maintenance, and governance of the water supply system. This is done for the local community, in collaboration with the local authorities. The project plans to implement smart water meters and smart payment for the system operation. These features will significantly reduce operational difficulties, staff requirements, and simplify the payment process for the users. In addition, installation of smart meters will allow the system to record water consumption data and locate leakages in the system. After the project is completed, the system will be handed over to Madi Municipality, which will be responsible for operation and maintenance.

EnviDan has also been involved in a major communication effort to increase awareness of how important it is for the inhabitants to register in the new drinking water system. More than 85% of the users have already signed up for the new system.
