2.1 技术简介

技术定义:

Ground Water Recharge in Nyhakka Chuke tole for Domestic use.

2.2 技术的详细说明

说明:

Due to increasing population and urbanization along with unmanaged settlements in and around the core city areas in Lalitpur existing ground water dries up while the water levels in well is decreasing alarmingly. However with initiation of rainwater recharge programs in areas in 2009
locals from around 150 houses around nyakha chuke tole and adjoining areas in lalitpur get their water supply with sucessful replerishment of their underground aquiter through rainwater harvesting.the dugwells are being sucessfully replerished due to rainwater recharge system.

Purpose of the Technology: This technology is mainly applied to replerish ground water aquiter to support around 20 different committee in Lalitpur.
This aims to make people aware of the recharge mechanism and augument ground water level.

Establishment / maintenance activities and inputs: The credit for implementing this technology must go to local people participation. It is only because of the cooperation among themselves that make them realize current alarming problem and made them collect money for implementing recharge system.They have done it with external material support such as food-work, payment, subsidized machinery.
Regarding maintenance activities , women living around nyhakha chure tole are responsible for cleaning areas where technology has been implemented. Besides , water content in dug well are tested every six months to make sure that water is suitable for drinking that is free from ions and other chemicals . As well as different machine such as pump are checked every six months and are replaced if damaged, with the money collected from different house hold.

Natural / human environment: The implementation of this technology or system has made availability of water for various domestic use by supplying the water in each and every houses.It also has helped increasing harmony and mutual understanding among the people living there by. In past years people use to fight for getting water. there were fight between two locality for water . Ground water recharge system has increased water sources . There is proper distribution of water. Now people do not have to disturb their sleep for getting water like before.this has even helped to improve living standard and health of people.
