Comprehensive overview (in form of factsheets) on the different components of wastewater treatment systems (collection, transfer, onsite treatment, centralised and decentralised treatment, reuse, sludge management and disposal) adapted to the Caribbean Region. Industrial wastewater treatment is also discussed.

In 2000, three pilot ecosan toilets with agricultural reuse were setup in two Ugandan districts. Operation and maintenance by the end users proved a nightmare since sustainability, multicultural and religious issues were some of the aspects initially not considered. This led to the failure of the system to separate faeces and urine and be able to dehydrate the former. Further sensitisation of the population was repeated and after three months the operation and maintenance of the system improved.

Lake Victoria Environmental Management ProjectThis report of a group project by the University of Cranfield assesses the effectiveness of Key Performance Indicators (KPI) in measuring progress along the results chain. The assessment is conducted by analysing different Monitoring and Evaluation (M&E) approaches in the WASH sector and leads to recommendations for the Centre of Affordable Water and Sanitation Technology (CAWST) to incorporate into their M&E approach.

The city of Kuching is currently lacking a wastewater treatment plant, and the local subsurface conditions make a conventional centralised wastewater system expensive to implement. Most buildings are equipped with two separate wastewater outlets, one outlet for blackwater and one for greywater. The proposed system treats greywater from nine households, and consists of a baffled septic tank, followed by a dosing chamber from where the greywater flows into four vertical down-flow, single-pass aerobic biofilters before reaching a subsurface horizontal-flow planted filter. Finally, the treated greywater is discharged into a stormwater drain.
