This report describes the particular problems low-income, semi-urban communities face concerning waste water. For a large number of communities modern sewage systems are feasible nor desirable. These communities and local authorities will have to look for alternative ways to treat and dispose of waste water in a safe and ecogically sound way, without having to rely on the central government for technology selection, implementation and maintenance.
In the valley of Nepal's capital city Kathmandu many of such communities exist. A workshop was held with representatives from four of these communities to map out their particular problems concerning waste water and taking the following principles into account a variety of possible solutions to solve these problems were discussed.
1. As much as possible separate collection and composting of dry, black waste, through toilets in the homes or toilet blocks with private or public double vault latrines and mixing it with cowdung, straw and ash. Composting of black waste can be made a profitable bussiness.
Possible solutions included the use of toilets allowing composting of black waste, improvement of existing gutter systems for stormwater in order to recharge groundwater and constructed wetlands for treating grey water.
Acknowledging that effective management structures are as important as appropriate technical options, elements for a proposal for applied research were put together, which includes starting broad consultation processes, detailed investigation, participatory selection of the most appropriate technical and managerial solutions and experimenting with these solutions.
