Key Issues and Recommendations
Issue
Less than 5 percent of
urban wastewater is
currently treated
Recommendations to Address Issues
1. Conduct citywide sanitation planning through City
Sanitation Strategy, focusing on the development of
centralized systems in highly urbanized areas while
ensuring that low income communities and eradication
of open defecation are prioritized.
2. Continue Decentralized Wastewater Treatment Systems
(DEWATS) program in locations where centralized
systems are not viable, but with consideration of
comparative costs, required effluent quality and O&M
constraints.
3. Focus future DEWATS approach on provision of
decentralized systems with sewerage networks.
4. Expand coverage of centralized sewerage more rapidly
through a staged approach initially using combined
sewerage and interceptors before transitioning to
separate systems.
5. Design treatment facilities and set effluent standards to
take account of influent and receiving water quality.
