A center to solve Kathmandu’s water woes




A rainwater resource center has been established in the capital with an aim to find a solution for the festering water crisis in the Kathmandu Valley.
The resource center will provide overall information on technology and process for rain water harvesting and treatment, according to Anil Sthapit, director of Guthi, the non-government organization working on water, sanitation and hygiene (wash) sector.

The center established at the premises of Lainchaur-based Nepal -Japan Library by the Center for Integrated Development (CIUD) in support of the UNDP will provide information to the people on the methods of rain water harvesting.

Likewise, a rain water collection technology has also been installed in the library so that the visitors could receive comprehensive knowledge on applying it at their homes and community, said Jeevan Kasula, a program officer at the CIUD.
Likewise, the resource center will also provide technical assistance to those Kathmanduties who show interest to build the recharge and collection unit at their residence or locality, he added.

According to Sthapit, around 7,000 rainwater recharge and collection units have already been established in the valley whereas the network of the NGOs aims to establish a thousand more of such units within this fiscal year.
The Kathmandu Valley receives 120 billion liters of rainfall annually. The CIUD estimates that as much as 320 million liters of water can be stored through rainwater harvesting even if half the quantity of the total rainfall is harvested.

Thus, the rainfall on 300 square kilometers of the valley is sufficient to meet the demand for water for 525 days, which means rainwater harvested during a monsoon can generate water for one and half years, according to the government´s rough estimation.

Unmanaged urbanization as well as population growth has created huge water crisis over the years which does not seem to be sorted alone from ground water that Kathmandu Upatyaka Khanepani Limited (KUKL) extracts and distributes to the valley dwellers.
Likewise, the Melamchi drinking water project is also uncertain and the statistics have already proven that it would also be insufficient for the ever increasing population of the valley.

In such situation, rain water harvesting is a reliable source to store water and use in dry season, he added.
There is a demand of 320 million liters of drinking water in the valley for 3.2 million people. While the KUKL has the capacity to supply 150 million liters of water during the rainy seasons, its supply capacity drops to 90 million liters during the dry seasons.

The Kathmandu Valley Water Supply Management Board in 2010 had signed an agreement with the NGO to promote rainwater harvesting in the valley. Likewise, another contract was finalized last year with the CIUD to generate 500 million liters of rainwater.
The government and the CIUD were able to achieve the target within the time, says Kasula. The CIUD had achieved another target of generating 800 million liters of water through rainwater harvesting last fiscal year.
