The Challenges

“In particular, you should highlight successful institutional and technical arrangements to ensure that privately collected sludge is delivered to a suitable treatment or disposal site, and the overall system planning required to make this practicable”.

«En particulier, il faudrait mettre en évidence des arrangements institutionnels et techniques réussis qui assurent que les vidangeurs privés acheminent les boues collectées vers une station de traitement appropriée ou une décharge. Démontrer également le processus de planification nécessaire pour aboutir àcela».

(Pete Kolsky, World Bank)

Promising Innovations

The private sector collects and treats the FS(The case of GIE* Sema Saniya in Bamako, Mali)

Construction of an FS treatment plant by a GIE already in charge of FS collection

Financing foreseen through the sale of biosolids to farmer and by disposal fees from other enterprises

* Kind of local NGO (French: Groupement d’Intérêt Economique)

Initiative of the Private Sector in Bamako

- The faecal sludge of GIE reach the treatmentplant thanks to the interest of the emptiers

- Reuse of the residual product (biosolids)

- Close economic and service relationship between client and enterprise

- …

Challenges

Innovations

Conclusion

Outlook

SandecWater and Sanitation in Developing Countries

- High financial risk for GIE- Third-party emptying companies do not deliver

the FS at the treatment plant for reasons ofadditional costs and long distance

- Existence of a market for the sale of the residual product is compulsory

- …

Municipality Involved in Kumasi (Ghana)

The municipality of Kumasi is in charge of the FS treatment plants

The municipality issues licenses allowing private emptying companies to carry out the work

In the event of indiscriminate FS dumping, the emptying company risks to lose its license

Conclusion

Outlook

SandecWater and Sanitation in Developing Countries

- Requires a strong municipality to control and enforce FSM

Reversed Money Flux in Ouagadougou (Burkina Faso)

Challenges

Innovations

Conclusion

Outlook

SandecWater and Sanitation in Developing Countries

Strategic plan:

Treatment of wastewater and faecal sludge on the same site is managed by the municipality

It is planned that the emptying companies are reimbursedfor delivering the faecal sludge at the treatment plant

The operating costs of the treatment plant are financed by the drinking and wastewater fees and by the connection charges to the sewerage system

Conclusion

Outlook

SandecWater and Sanitation in Developing Countries

Promising initiatives exist worldwide to improve faecal sludge management.

The innovations are multi-faceted and based on financial, institutional, technical, and socio-economic tools.

There is no universal remedy ! Since each situation is case-specific, integrated solutions adapted to the local conditions are required.
