Tender Details

In February 2021, 3P RenewablesSwitzerland SA (3PRS) was awarded a decree by the Congolese government for thedelegated management of developing and operating new drinking water productionfor the Pointe Noire urban area in Gambouissi Lake (the "Project").The project aims to reinforce drinking water production capacities, enablingLCDE to better meet the water demand of Pointe Noire.In 2023, IFC and 3PRS signed acollaboration agreement to co-develop the Project. As part of thecollaboration, IFC conducted an initial technical review of the Projectwhich noted that there was a lack of information regarding 1) hydrologicaldata, 2) existing uses of the raw water, 3) hydraulics of the Lake, 4) rawwater quality, and, most importantly, 5) available flow of raw water for theProject. Also, the variability of all these elements considering seasonality(dry/wet season) was not clearly defined. As a preliminary mitigation measure, and to discard the raw water availability risk as a deal breaker, IFC mandateda consultant to subsequently perform a pre-hydrological mission to check theflow exiting the Gambouissi Lake (over a few days during the month of September2022 - September being the last month of the dry season and thereforepotentially presenting the worst conditions of the year in terms of wateravailability). The measured flow appeared to be sufficient during low-waterperiods, but only to operate at least one compact water treatment unit (nominalcapacity of 750 m3/h).Due to the nature and reduced scope ofthe pre-hydrological mission, there remains a need to perform a hydrologicalstudy, in particular to 1) confirm the availability of water in terms ofquantity and quality, 2) characterize the origin of the water and thesustainability of the Lake as a resource, as well as 3) define the impact ofthe water abstraction (downstream).
