Improvements to 80 MGD Enrique Ortega (La Plata) Water Treatment Plant at Toa Alta, Puerto Rico
Client: Puerto Rico Aqueduct and Sewer Authority
Construction Value: $130,000,000
The 80 MGD Enrique Ortega (La Plata) WTP is the second largest water treatment facility of Puerto Rico. The improvements are directed to guarantee finished water quality and improve the process control of the treatment plant. The project consisted in the upgrading of the chemical injection, coagulation, sedimentation and filtration processes; and the installation of a plant control system. The engineering services included: (1) permitting, (2) field survey, (3) subsurface exploration, (4) written design report, (5) cost estimate, (6) technical specifications, and (7) construction drawings.
Improvements to 25 MGD Ponce Nueva Water Treatment Plant at Ponce, Puerto Rico
Client: Puerto Rico Aqueduct and Sewer Authority
Construction Value: $12,000,000
The 25 MGD Ponce Nueva WTP is the most important water treatment facility in the south of Puerto Rico. The improvements are directed to guarantee consistent compliance with the SDWA DPB Rule Stage 2 and the terms and conditions of the Transactional Agreement between the Puerto Rico Aqueduct and Sewer Authority and the Puerto Rico Department of Health. The Ponce Nueva WTP is compliance with LT2ESWTR was also evaluated. The project included the upgrading of coagulation process, retrofitting of existing pulsation clarifiers with high-rate hydraulic pulsation clarification, upgrading of filter basins and installation of closed vessel UV reactors to achieve 3-log removal/inactivation of Cryptosporidium and 4-log inactivation of viruses. The engineering services included: (1) Preliminary Engineering Report (PER), (2) permitting, (3) field survey, (4) subsurface exploration, (5) written design report, (6) cost estimate, (7) technical specifications, and (8) construction drawings.
Yauco Water Treatment Plant Membrane Expansion to 7.6 MGD at Yauco, Puerto Rico
Client: Puerto Rico Aqueduct and Sewer Authority
Construction Value: $20,000,000
The existing Yauco WTP was expanded to 7.6 MGD to meet the year 2030 projected water demand and improve the water treatment process to comply with the expected short-term drinking water regulations as per the SDWA. The project included the upgrading of the chemical injection, coagulation and sedimentation processes, and converting the existing filtration basins into immersed low-pressure ultrafiltration membranes. It also included the construction of two (2) additional membrane trains, a new chlorine contact tank, a finished water pump station, a sludge treatment system and a new process control system. The engineering services included: (1) permitting, (2) field survey, (3) subsurface exploration, (4) written design report, (5) engineering design, (6) technical specifications, (7) cost estimate, (8) construction drawings and (9) construction supervision.
