The spatial planning approach for urban solid waste management of Sri Lanka.
By Admin | March 19, 2009
The urban solid waste management is an obligatory function that is assigned to local authorities to serve in the manner that secures the environmental sanitation of local population. Finding land is being a complex problem. At present solid waste management consists of collection and ad hoc disposal of waste on low lying areas or vacant lands. The reason for this issue is scarcity of lands and the finding land itself is a complex problem. The inappropriate land selection is one of the major reasons to failure of earlier attempts in solid waste management.
Integrating the all aspects physical, social, economic and environment is the sustainable way to mange MSW in any country. But majority of our local authorities are not strengthened mainly due to lack of knowhow, resources legislation and intuitional arrangement. This paper discussed the spatial planning interventions to the urban solid waste management.
Solid waste management includes waste generation, collection transportation, processing and final disposal. In the process of urban waste management, spatial planning decisions should be effectively derived in each stage to reduce the waste added to solid waste stream, maximize the resources recovery and dispose the waste at appropriate sites. The case study was carried out at Dehiwala waste management zone which comprises seven local authorities such as Dehiwala Mount Lavinia MC, Kesbbewa UC, Boralesgamuwa UC, Maharagama UC, Homagama UC, and Seethawakapura PS which covers 483.5sqkm.Formal questionnaire survey has carried out interviewing the Public health inspectors, Environmental officers, and the staff members of local authorities who involve in the solid waste management process. The analysis was based on waste generation, composition, segregation, collection, recycling, processing and disposal of waste in different local authorities. The land suitability for disposal of waste has carried out using GIS model builder application. This test was based on physical, social, environmental aspects. In addition the finding of this research indicates the importance of centralized approach in solid waste management.

Homagama is still PS not an UC.
