Sewage Plant, Chevron Escravos


We were contacted on problem with leakage on just completed Sewage Treatment Plant. We visited site and identified that the Reinforced Concrete Primary Clarifier (1 unit), Secondary Clarifier (4 units) and the Aerobic  Digestion  Tanks  (1  unit)  were  leaking  from  all  the construction joints, some pipe connections, random damp patches and at the base of the Tanks.
