| Summary: | Effective management of sanitation and
wastewater is a growing challenge in dense urban
settlements. Rapidly increasing urbanization and, along with
that, rising settlement densities in low-income urban and
peri-urban areas highlight the need for sanitation
technologies and management systems that are robust and
affordable, and which lessen the pollution load on local
water sources. In many developing countries, centralized
sewerage and wastewater treatment systems cover only a
portion of larger urban areas, and are often not yet planned
for smaller towns and densely populated, low-income areas of
cities. On-site sanitation is often inappropriate in the
denser settlements and slum areas, thus requiring
intermediate and complementary solutions. Decentralized
wastewater treatment systems (DEWATS) connected to
simplified sewer systems or communal sanitation centers have
the potential to close the gap between on-site and
centralized systems. Community-managed DEWATS offer the
possibility of swift sanitation improvements in high
priority neighborhoods that communities can manage
themselves, where local government does not yet provide a
full sanitation service. This review explores
Indonesia's experience in implementing
community-managed DEWATS on a growing scale, and more
specifically, whether community-managed DEWATS are a viable
urban sanitation option for serving poor households in dense settlements. |
