One step closer to securing clean drinking water in Nepal
In Nepal only 50% of the population have access to piped drinking water and design standards, and technical abilities within water supply are less than existing. Since 2019, the Danish organization, Jysk landsbyudvikling i Nepal, has been working on a project to ensure clean drinking water for several villages and has hired Envidan to carry out the technical work on establishing a reliable and hygienic water supply.
Back in March 2022, the final contracts were signed. The solution's design has now been approved, the entrepreneurs are found, and the construction phase has already been initiated where Envidan alongside several Danish companies, including Grundfos, Kamstrup, and AVK, are bringing their expertise to the construction site.
The project is being supported by the Grundfos Foundation and carried out in close cooperation with local authorities as well as Jysk landsbyudvikling i Nepal’s local partner organization MIISDP in Madi, Nepal.
Clean drinking water – also when the project is over
The purpose of the project is to establish a sustainable water supply network for three villages and thereby ensure clean drinking water for approx. 420 families. The water supply network must have sufficient capacity to deliver 65 liters of clean water per inhabitant per day, as determined by Nepali guiding standards. The project is expected to eliminate the drinking water shortage in the area, and this year, among other things, a new water supply system has been designed locally and deployed.
Water2Nepal will support and establish an effective framework for operation, maintenance, and administration of the water supply system. This is done in collaboration with the local authorities. In the project, the parties plan to implement intelligent water meters and intelligent payment for water consumption, which will reduce operational difficulties, personnel requirements and secure the economy through an efficient payment system. In addition, the installation of intelligent meters will enable the system and record water consumption data and locate leaks in the system.
When the project is completed, the system will be transferred to Madi Municipality, which will be responsible for operation and maintenance.
An efficient and sustainable drinking water project
Envidan carries out all the technical installations such as design, project management and quality control. An important aspect of the project is also to
test technologies and solutions to investigate how, water supply can be organized from scratch in an area with poor sanitary conditions. This must be done by drawing on knowledge from the Danish water industry. Different possible solutions have been analy
sed, but a simple yet effective solution has been chosen based on the available resources and technologies.
To determine the need for supply, a hydraulic simulation was carried out to dimension the water supply system. Solar energy is the primary power source for the submersible pump, which lifts water from the 100 m deep aquifer to the water tower, which has a capacity of 285 m3. The supply from the water tower will be based on gravity which, combined with pumps powered by solar energy, ensures lower operating costs and relatively low water charges.
Local anchoring and involvement
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 to provide technical services during the operation and maintenance phase.
Envidan has also been involved in a major communication effort to raise awareness of how important it is for residents to register in the new drinking water system so that they can secure clean drinking water in the future. More than 85% of citizens have already registered for the new system by paying the connection fee. Through collaboration with Kathmandu University and OXFAM Nepal, the project also focuses on training local engineers and technicians.
A project in several phases
The project, which helps ensure clean drinking water for the Nepalese villages, is divided into several phases, where several employees from Danish supplies are volunteers on the project. Envidan has sent engineers on several occasions to visit Nepal and work on the project. Most recently, Project Engineer Surya Prajapati went to work on the next phase of the project, where he, together with business partners, supervises the construction of the wiring system and the height container, etc. With him is Hamon Hedayat, who in addition to participating in the work to establish a safe drinking water supply has also been allowed to use the project in his field studies in connection with the completion of his engineering studies.
Info about the water supply system:
- Approximately 420 families
- Approximately 4000 people
- Daily demand: 350 m3
Elevated Water Tank
- Total volume: 285 m3
- Total elevation above ground: 28 m
Water Distribution System Mains
- Approximately 16 km long main pipeline with pipe sizes varying from 63 mm to 200 mm
UN global goals
How the project contributes to the UN's global goals:
With the Water2Nepal project we will improve life in Nepal and at the same time develop design criteria that will be applicable in many countries. Our work will contribute to SDG1, SDG3, SDG4, SDG6, SDG7, SDG12, SDG15 and SDG17. The project thereby supports several of the UN's World Goals, but especially Goal 6: 'Clean water and sanitation' and Goal 17: 'Partnerships for action'.
