The community latrine was put for common use with effect from 15 March 1998. At present, the latrines are  being visited by 250 regular and 35 occasional users per day. Thus, from 285 latrine visitors about 115 kg of human excreta is available per day as raw material for feeding the biodigester (0.4 kg of faeces per person) from which about 5.75 m3 of gas production is expected per day. Currently, the gas is being used to provide illumination inside the latrines. Thus, two lamps consuming each 0.07 m3 gas per hour are lit for about 10 hours during night. Although it was envisioned to provide the excess gas to the interested household (s) located close to the project site. this plan has not been materialized as yet. 

Two compost pits with dimensions of 1.5 m x 1.5 m x 8.0 were constructed beside the biodigester for storage, treatment and utilization of digested effluent from biodigester. The watchman uses a part of slurry to fertilize his kitchen garden. But still there seems a need for practical and demonstrative type of training to local people to acquaint them in managing the biodigester for proper utilization of the slurry. Having monitored the project for a considerable length of time, CMS had suggested UNHCR in March 1999 to conduct such demonstrative training-cum-workshop on operation, maintenance of latrine-cum-biodigester and proper utilization of slurry by involving the local people of  Ward No.1 of Pathari. As a result of such training, the farming community are expected to be motivated to utilize the digested slurry properly as fertilizers. 

It is obvious that digested effluent (called slurry) from biogas plants contains very less harmful germs than the crude excreta and such slurry has already been proved to be high quality organic fertilizer for  plant nutrition. Studies carried out in China also shows that when processed in a biogas plant, more than ninety-five percent harmful germs contained in human excreta are destroyed. Therefore, the effluents are safe for handling compared to raw excreta. For proper care, maintenance and repair of the latrine, nominal fees are charged to the latrine users. The total income from the latrine amounts to Rs 2,700 per month (i.e. Rs 2,500 from the latrine users and Rs 200 from the sale of kitchen garden). The monthly salary of the watchman (around Rs 2,000 per month) and the occasional maintenance charge (Rs 400) is well balanced  by the net income of latrines.

He had worked as a Soil Scientist in the Department of Agriculture (1962 - 1977), as a Reader in Soil Science in Tribhuwan University (1977 - 1980) and as an FAO Consultant in more than 20 countries of Asia, Africa and Latin America in the field of Biogas and Organic Recycling (1980 - 1991). While in Nepal, he has executed a number of projects on organic recycling, biogas, solar energy and alternate energy sponsored by FAO, SNV, UNHCR, USAID etc. as Project Coordinator. He has participated in several national and international seminars on organic recycling and biogas technology. In the last six years he worked as Chief Technical Adviser of CMS, a consultant firm in Nepal. He is the Professor of Nepal Engineering College.
