Improvement drinking water supply Parakou, Benin

ORIO project (100% development phase, 50% finance implementation phase) executed by Brabant Water and SONEB

Posted on 6 August 2014


The water supply of Parakou, Benin (West Africa) is at risk: due to siltation the water storage in the reservoir Barrage d'Okpara, has lost a substantial part of its original storage capacity; due to destruction of the emergency overflow (spillway) the dam is becoming instable. In addition, the quality of the raw water is threatened.

As a result, in the near future, SONEB (national drinking water company of Benin) will not be able to offer sufficient water to the growing population of Parakou of good quality.

SONEB  and Brabant Water started in 2013 a project (funded by ORIO) to improve and safeguard the production and transfer of raw water, its treatment to potable water and the distribution to the population of the city of Parakou and two rural villages.
