In response to the dilapidation, insufficient dimensions, and relocation of administrative buildings within the Saint-Louis and Matam airports' complexes, our expertise came to the forefront. The existing water supply and sewerage infrastructure proved unusable during the airport's reconstruction, necessitating our provision of preliminary and detailed design for entirely new systems.

To ensure comprehensive water supply, accommodating both potable and fire-fighting needs, we devised a new water supply network. For water supply resilience, considering the unreliability of the local network, limited connection capacity, and local climatic conditions, a two-week water reserve was strategically implemented through a water tank, with the pumping station. The tank's volume is precisely planned based on the water needs of all consumers.

Given the absence of existing public sewerage infrastructure, impermeable septic tanks and a new sewerage network were meticulously designed for the collection and evacuation of sanitary wastewater. Addressing the absence of a local sewerage network, we designed a pipeline and impermeable concrete cesspits, ensuring efficient collection and evacuation of wastewater.

We hoped this project would showcase our dedication to resolving complex hydraulic challenges in the face of infrastructure limitations, employing meticulous design for optimal functionality and resilience.
