Study the optical properties of drinking water supply by KUKL and KVWSIP in Kathmandu Valley

Abstract

The optical properties of two water supply samples Kathmandu Upatyaka Khanepani Limited (KUKL) and Kathmandu Valley Water Supply Improvement Project (KVWSIP) in the Kupondole Area, Lalitpur, Nepal show that the transmittance of light is higher for KVWSIP sample water than for KUKL. A large amount of work has been done to test the purities of KUKL and KVWSIP water supplies (chemically), but even their optical properties have not been studied. This method has no hazardous side effects or requires chemical method testing. In comparing the optical properties, the authors recommended that the public take KVWSIP water for good health and wealth rather than KUKL if they have an option.This is because KUKL is more contaminated and has more total dissolved solids (TDS) particles, while KVWSIP has fewer TDS particles. Therefore, if people take KVWSIP water in their daily life, they obtain relief from different types of water-related diseases.

The Effectiveness of Clean Water Services of PAMSIMAS Program in Marioriwawo District

“…Service Effectiveness The effectiveness of public services can be seen from the level of success of services that have been provided to the public according to the goals or objectives of the public service itself [1]. PAMSIMAS program services can be said effective if the PAMSIMAS program is able to realize its goal, namely to increase public access to sustainable drinking water and sanitation services in rural areas.…”

“…Water is a special type of liquid used for different purposes and makes life possible on our planet [1]. Clean water is one of the basic needs that are indispensable for human life in a sustainable in order to improve the health status of the community.…”
