We worked on a comprehensive hydraulic project aimed at modernizing and securing a water pumping and distribution system.
The work included the supply and installation of a piezometric level sensor, as well as two additional level bulbs allowing for a switch to backup mode in the event of failure. The old pipes and distribution chamber were removed, and a 25 cm layer of compacted sand was excavated for storage. Filter sand that meets technical recommendations (DTU – grain size 02/04 mm) has been installed, ensuring better filtration and durability.
We then installed two overhead power supply networks:
- A DN 110 mm discharge network
- Feed combs in DN 50 (HDPE 63 mm)
The lifting station has also been reinforced with the replacement of the grating with a fiberglass-reinforced polyester model, and the chains on the lifting pumps have been replaced with 316L stainless steel chains for improved corrosion resistance. Finally, a Merill C1000 frost-proof faucet was supplied and installed to ensure reliable use in all seasons.
Careful design for performance, safety, and sustainability.
Details of the project
Primary treatment
- A decanter-digester with a diameter of 4.5 m, a height of 3.4 m, and a volume of 54 m³.
- A lift station equipped with an aerator-floater and two pumps. The structure has a volume of 5 cubic meters, a surface area of 3.8 square meters, and a height of 2 meters.
- The pumps at the all-water station are controlled using level bulbs.
Sand filters
- Two filters covering a total surface area of 460 m² fed by above-ground drains
- Filters are alternated once a week.
Discharge structure
- Sampling port
