Zero Discharge Mechanical Treatment System

The firm performed hydraulic and process design at the Palmas del Mar wastewater treatment plant, which has a capacity of 200 lt/s. The plant incorporates an innovative hydraulic design for which allows the entire process to work with a single pumping station. It is the first facility in Puerto Rico which recycles 100% of the effluent (used for irrigation) as well as 100% of the sludge (for composting). This facility received the award for “Best Engineering Project of the Year” in 1994 by the Engineer’s Association of Puerto Rico. (Design prepared in conjunction with Pacheco Engineering.)
