Management of Municipal Wastewater

Recommendations and an action plan

Municipal wastewater discharges (that is, the wastewater discharged from households, commercial undertakings, small industries and hotels) into freshwater and coastal environments can result in: (a) pathogens that may result in human health problems, (b) increase in suspended solids, (c) significant nutrient inputs, and (d) higher levels of biochemical oxygen demand (BOD). The state and the health of the oceans are thus closely related to ecosystem and public health concerns and food security issues.

Recommendations for decision-making, adopted in November 2000, highlighted the need for stakeholder involvement, financial affordability and an integrated approach.

Under a strategic action plan adopted by UNEP, assistance in management will include: a global knowledge base, recommendations for decision-making, regional meetings for cooperation, and a global consultative process on procedures and practices. "It is therefore essential, in devising a sewage management strategy, to begin by identifying the environmental problems to be addressed and the contaminants that cause them. Expensive nutrient removal technology, for example, is irrelevant if the problem is microbiological contamination."
