Wastewater Sanitation

At Hydroconcept, we design sustainable sanitation solutions suited to urban and rural realities. Drawing on our hydraulic engineering expertise, we support local authorities and private developers in managing the entire water cycle, ensuring hygiene, public health and respect for the environment.

Studies, Design & Rehabilitation

Sanitation is the backbone of any development project. It ensures the smooth collection and conveyance of wastewater and stormwater. However, a poorly sized network can lead to flooding and major health risks.

That is why Hydroconcept gets involved from the study phase. Whether for new works or the rehabilitation of existing networks, we produce master plans, hydraulic sizing and impact studies. Our engineers use advanced modelling tools to design reliable, durable infrastructure that complies with the standards in force in Senegal.

Quality Control & Works Supervision
Technical rigour at every stage
Beyond design on paper, the quality of execution is crucial. Hydroconcept carries out the control and supervision of works on site. We ensure strict compliance with the specifications, the quality of the materials installed and the conformity of connections before the final acceptance of the works.

Our areas of intervention include:

Our expertise covers the entire liquid sanitation chain, from collection to discharge, including treatment. Whether for centralised sanitation projects (urban networks) or on-site sanitation (scattered areas), we provide a precise technical response to topographical and demographic constraints.

Design of gravity and pressurised networks.
Design of pumping stations and wastewater treatment plants (WWTPs).
Stormwater management and retention basins.

OUR QUALITY & ENGINEERING COMMITMENT

Whatever the complexity of your project, our methodology remains the same: absolute technical rigour and a long-term vision. Hydroconcept mobilises its engineers to guarantee the performance, safety and profitability of your infrastructure.
Expertise & Design

We use the latest modelling tools to design precise structures. Every study begins with an in-depth site assessment to avoid unforeseen issues.

Cost Optimisation

Good engineering must be cost-effective. We size your projects to what is "just right" to minimise your investment and reduce future maintenance costs.

Standards & Compliance

We guarantee strict compliance with Senegalese and international standards (QHSE). Your projects are designed to be approved without reservation by the regulatory authorities.

Monitoring & Delivery

Our mission does not stop at the drawings. We provide rigorous quality control during the execution of works to ensure that the final result matches the studies.

NEED EXPERT ADVICE?

Sanitation is complex. A poorly maintained or poorly designed network can lead to backflows, unpleasant odours and serious health risks. Don’t let the situation deteriorate. Our engineers are available to assess your installations and recommend the right technical solutions.

THE KEYS TO AN EFFICIENT SANITATION SYSTEM

To ensure the longevity of your networks, regular maintenance is essential. Septic tanks must be emptied periodically and pipes cleaned to prevent the build-up of grease and sand that causes blockages.
Watch out for early warning signs: slow drainage, gurgling noises in the pipes, persistent odours or unusual dampness on the ground. These symptoms often point to clogging or a ventilation fault that must be dealt with quickly.
It is crucial not to discharge rainwater into the wastewater network (except in combined systems). This saturates treatment plants and causes surface overflows. Hydroconcept helps you design compliant separate networks.
In Senegal, the discharge of wastewater into the environment is strictly regulated. Our treatment solutions (WWTPs, filters) ensure that your discharges comply with current environmental standards, protecting you from any administrative penalty.
