About Us

Welcome to Waste Management Authority

Disposal of Solid Waste has become one of the major environmental issues in Sri Lanka. Dumping of garbage on road sides and sensitive areas such as wetlands, marshy lands, reservation etc. is a common practice adopted by the public and some local authorities. This is due to the attitude of people towards the disposal of garbage and the difficulties faced by the relevant institutions due to their inability to handle proper methods to solve the problem.

Waste Management Authority - Western Province which was established is a government body that focuses on waste management systems for the most populated region of Sri Lanka. The Western Province produces 3,500 metric tons of waste per day, which is 60 percent of the country's total. Waste Management Authority WP registers recyclers, monitors 21 composting facilities for food waste, and offers training, technical guidance, and programs on waste reduction, home composting, biogas, and recycling. The compost is sold under the brand name Mihisaru.

Organizational history

To overcome severe problems related to inappropriate solid waste handling the Western Provincial Council (WPC) explored the possibility of implementing an effective mechanism to address the issue. In 1999, the Chief Minister and the Minister of Local Government of the Western Province, succeeded in setting up an Authority for waste management.

In 1999, the Waste Management Authority (WMA) Statute No. 09 of 1999 was passed at the WPC and in 2004 Waste Management Authority of Western Province (WMA(WP)) was formally established. This pioneering Authority established since the 13th Amendment to the Constitution handed over the administrative and management roles to provincial government. WMA(WP) is still the only specialized authority for waste management at provincial level.

As this was the first innovative step in provincial waste management process in Sri Lanka, it took time to organize its administrative structure, cadre approval and recruitment of essential staff to run the authority effectively.

At the start there was a heavy demand of service requirements by various segments of the province such as Local Authorities, political leadership, government institutions responsible for health and environment, civil societies and the general public for the long overdue waste related issues. To fulfill these requirements technical assistance from donor organizations were sought in 2004 and the USAID/USAEP came forward and formulated a joint program with the government of Sri Lanka and WPC, to streamline and build the capacity of the WMA(WP). With the USAID/USAEP technical and financial assistance program in 2004 and 2005, WMA-WP identified innovative strategies for administration, technical and legal application for the deliberation of services of the WMA (WP).

Under the same USAID/USAEP program, the WPC further strengthened the legalities of WMA with the Waste Management Authority Statute No. 01 of 2007, incorporating innovative features such as establishing an advisory committee on waste management, introducing a penalty system and empowering local authorities to make by laws
