Tanzania: INNOQUA demo site in Mlalakuwa

Mlalakuwa sub-ward is located in the eastern part of Dar es Salaam. It has a population of 19,000 people living in approximately 1,000 households. Nearly 80% of the population use pit latrines (35%) and septic tanks (45%) as the main form of sanitation. Most of these facilities are emptied using illegal or unsafe practices, such as manual emptying with a bucket, “flooding out” or direct discharge to nearby water sources.


The INNOQUA system will treat the wastewater from five households and will benefit 37 people from a middle and low-income community. The treated wastewater will be used for irrigation of an existing banana plantation.

Source of Wastewater: Toilets and shower

Specific Scientific Research Objectives:
To assess the potential for Tanzania’s sanitation sector to transition towards sustainability, through the integration of innovative decentralised sanitation systems with safe re-use of treated wastewater.

In Tanzania the INNOQUA system consists of a lumbrifilter, daphniafilter and UV lamp, installed on the outflow from a septic tank.
