Guwahati City is facing a serious threat from the growing generation of municipal waste. The performance of municipal waste collection and disposal system in the city has been observed to be very poor. After introduction of Integrated Solid Waste Management (ISWM) programme, the waste scenario is found to be more miserable. In a few places of Guwahati city, some local private bodies provided services of waste collection and disposal in their respective localities in terms of monthly payment before the ISWM programme. But advent of ISWM has created confusion among the beneficiaries regarding the efficiency of services and monthly payment procedure. A study has been made to find out the Willingness to Pay (WTP) of the people of Guwahati city for local private service for waste collection and disposal purposes along with the studies on municipal waste management of the city. A comparative study has also been conducted to find out the preference of the people for both the ISWM.
