The construction of this new WWTP solves the problems posed by the former Moncofa WWTP and the Belcaire WWTP. The former Moncofa WWTP is less than 200 m away. of the buildings on the beach. It includes capacity problems due to its low slope and with the discharge point at 300 m. from the mouth of the Belcaire River into the beach area, and poses an environmental risk. The Belcaire WWTP, which serves the coastal developments south of the Belcaire River and the Casablanca industrial estate, provides modest facilities for the nearby residential area.

This new WWTP makes it possible to move the facilities away from the urbanised area, thereby minimising the negative impact that a sewage treatment plant may have on urban centres and further away from the point of discharge into the Belcaire River to its mouth on the coast.

The works consist of the construction of a new sewage treatment plant using activated sludge. A flow rate of 12,000 m3/day (60,000 inhab-eq) is divided into two treatment lines of 6,000 m3/day and consists of:
  • Water line: 2 pre-treatment lines (thinning, desanding-degreasing), 2 biological reactors in prolonged oxidation, 2 secondary decanters, tertiary treatment (filtering with textile discs and UV disinfection), chlorination channel.
  • Sludge line: thickened by gravity (1ud), dehydration by centrifuges.
  • Network of collectors:
    • Drive section of 469 m., using HDPE pipe DN315 mm and nominal pressure of 0.6. Mpa EBAR North I and EBAR Casablanca
    • Deodorisation system in EBARs using activated carbon
  • Tertiary treatment for the reuse of treated water, meeting the quality criteria established for urban uses, irrigation, industrial or recreational use. It consists of filtration in two filtration lines using fabric filters and final UV disinfection, with final connection to chlorination tank.
