The Metropolitan Waterworks and Sewerage System (MWSS) said the stalled P774-million Sumag River Diversion Project (SRDP), the most viable option to augment raw water supply and solve the water shortages in the near-term, will be completed by second quarter of 2022.
The project has obtained the quarry permit and certificate of precondition as part of the free, prior and informed consent of indigenous cultural communities that paved the way for its resumption of construction last month.
It benefitted from Administrative Order No. 32 that expedites the review and approval process of water infrastructure flagship projects.
The project which is jointly funded by MWSS concessionaires was stopped in 2016 when a flash flood incident occurred after an excavation of the half of the 600-meter tunnel has been completed.
MWSS said the SRDP will interconnect the branch tunnel from Sumag river to the existing Umiray-Angat-Transbasin tunnel to shorten the refilling period of the Angat Dam by diverting inflows to the reservoir by 188 million liters per day equivalent to 2.2 cubic meters per second of raw water.
The agency said preparatory activities and excavation works at the tunnel intake, apron structure and pump concrete base have started but barging activities for transport of major equipment and materials can only be done by next summer. – J. Macapagal
