Introduction to Faecal Sludge Management
Slides - Week 5 10m. Further reading - Week 5 2h. For cities with or that are planning sewerage systems, co-treatment may enable citywide sanitation by minimizing the need for standalone fecal sludge treatment plants. For new sewerage programs, proper planning can enable co-treatment by appropriately sizing the wastewater treatment plants to handle the additional loading from septage.
For existing plants, evaluating their capacity to receive fecal sludge is needed to ensure that effluent quality standards can still be met. A recent study initiated by the Asian Development Bank Institute ADBI suggests that co-treatment system projects can exhibit both high net present values and internal rates of return. This offers a stronger potential for private sector involvement in the fecal sludge management value chain. Under co-treatment, the septage liquids can be effectively separated from the solids through mechanized units, such as the skid-mounted press see Figure 1.

This means that properly equipped decanting stations can be established at strategic locations along sewer line routes to minimize the distance septage delivery trucks have to travel to legally dump their loads.

Even if sewer lines are not available, small-space treatment options can reduce trucking distances and thereby have positive spillover effects. This indicates a potential entry point for private sector investment. Much of the spillover effects are obtained through the reduction in septage delivery truck travel time, which reduces the number of trucks required, fuel consumption, consumables i. The toolkit assesses variables, including the flow of septage per day, the capacity of the trucks, and drive times and distances, to allow for comparison of the spillover effects of sewerage systems with and without co-treatment capabilities.
For city or water utility-managed fecal sludge management programs to be sustainable over the long term, they must operate through tariffs that adequately cover the cost of delivering the service. Programs that reduce this cost can allow operators to i use the savings to expand the services to the urban poor, ii reduce costs to consumers, and iii in the case of the private sector, generate profits.
Effective programs can be designed to achieve all three. A public—private partnership between a private sector service provider that furnishes the equipment and runs the facility operator , and a city or water utility that generates a tariff revenue stream can be effective. The public entity collects the fees and subcontracts to the operator to perform the service.
EnviroKonsult in the Philippines is demonstrating the effectiveness of public—private partnerships with large cities for performing services related to fecal sludge management. Its project in Cordova, Cebu province is an example of private sector involvement in citywide sanitation.
It processes cubic meters of septage per day. In this case, they were able to install the system within the community being served, drastically reducing the travel time and maximizing the spillover effect value, making it an attractive investment for the firm. ADBI is continuing its work to refine their model by applying it to key cities throughout Asia.
