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)

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

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
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

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.
