Project Partner Kathmandu Valley Water Supply Management Board (KVWSMB)
Project Location Nepal
Project Duration Jul 2019 to Sep 2020
Description
Currently in Kathmandu Valley, faecal sludge from the containment tanks are neither desludged regularly nor emptied properly. Existing services not only for emptying/desludging the containments; but also, for their collection and disposal are not regulated to end them up properly aligning with environmental regulations. In fact, these services are often unreliable, considered illegal and incur relatively high costs to the building owners as well. Hence, untreated liquid effluent from the containment tanks ends up eventually in the surface water bodies i.e. rivers (Bagmati and Bishnumati) with adverse impact in the environment of in Kathmandu valley.
It is estimated that 70% of the households comprising 3.1 million people in urban and peri-urban areas of Kathmandu Valley are connected to sewerage networks. However, all the networks are not connected to wastewater treatment plants; and not all of the wastewater treatment plants are operational. Thus, a significant volume flows untreated into drains and rivers throughout the valley. It is further expected that over $1 billion is going to be spent on new sewers and Sewage Treatment Plant (STP) upgrades in the next 30 years of time.
To combat this situation, the Government of Nepal (GoN) is committed to improving the water quality in the Bagmati, Bishnumati and other rivers which flows through Kathmandu Valley carrying untreated flows. Part of the improvement includes upgrading and expanding the sewerage connection pipelines and improving sewerage treatment plants. Kathmandu Valley Water Supply Management board (KVWSMB), with support from Asian Development Bank (ADB), is updating the Capital Investment and Asset Management Plan (CIAMP2). An integral component to this CIAMP2 is water supply and wastewater plan for the period covering 2020- 2050 AD such that by the year 2050 about 90% of the residents will be served by the improved sewerage infrastructure.
General objective: To develop a conceptual faecal Sludge Management Framework for integrating FSM program into Wastewater Master Plan in Kathmandu Valley.
Specific objectives:
-
To develop FSM recommendations and cost estimates for the next 30 years.
-
To find synergies with the CIAMP2 being prepared by the KVWSMB for water and sewerage infrastructure, with financing from the ADB.
