The Puerto Rico Aqueduct and Sewer Authority (PRASA) on Wednesday launched a bid notice for the dredging of the Carraízo reservoir, which is located in the Río Grande de Loíza and is the largest source of drinking water supply for the area.

The project will be conducted through an estimated invest-ment of $76 million.

PRASA Executive President Doriel Pagán Crespo said in a written statement that the work includes dredging in the res-ervoir area, preparation and construction of the work area, and storage and handling of materials. The project also includes the preparation and rehabilitation of disposal areas for the extracted sediments (dams A, B and C), installation of sediment pumping pipes from the dredging area in the reservoir to the disposal areas of dams A, B and C, and likewise the management of dredged sediments in the dike area and disposal of clarifi ed water back to the reservoir.

Pagán Crespo added that “the objective of the dredging is to recover 2 million cubic meters … of storage capacity.”

“The Carraízo reservoir, which supplies the Sergio Cuevas fi ltration plant, would benefi t approximately 171,387 families in the municipalities of San Juan, Carolina, Trujillo Alto, Canóvanas, Gurabo and Loíza,” she said.

The project will be funded by the Federal Emergency Man-agement Agency (FEMA) under the FEMA Accelerated Obligation Strategy and the Community Development Block Grant Disaster Recovery program.
