The Beit Dajan's waste water treatment plant has been built in 2014, but due to breakdown of several components, effluent quality degraded and became unsafe for reuse and caused environmental harm. 

In the MENAWARA project, the following components of the plant has been rehabilitated:

o Influent Lifting Station: by installing 2 new submersible pumps;

o Pre-treatment Unit or 'Compact system’: by replacing the old disabled unit with a new one with an higher performance;

o Aeration Tank: by installing 2 new mixers, a DO meter, new flow meters and optimizing the aeration and desludging process (the sludge has good settleability not: F/M ratio and efficient BOD removal);

o Secondary Clarifier:  through the maintenance of the tank including cleaning;

o Equalization tank (EQ) & sandfilters: by constructing  EQ & the installation of 2 sand filters with 2 pressure pumps (showing the efficient removal of TSS by sand filters, reaching the standards);

o Chlorination unit: maintenance (incl. cleaning) and installation of dosage pump;

o Effluent Tank: new internal lining for the outlet tank.
