Set to Provide Short-term Additional Water
This is originally part of the Umiray-Angat Transbasin Project but was temporarily deferred during the construction of the transbasin tunnel. Considering the need to augment the raw water supply in the Angat Reservoir, now is the time to proceed with the construction of this Sumag River Diversion Works intended to divert raw water from the Sumag River through the existing transbasin tunnel with an estimated volume of 188 million liters per day (188mld).
The Project, which was being funded by the two (2) Concessionaires through the Common Purpose Facility (CPF) Office, was already bidded-out and the contract negotiation with the winning bidder is on-going.
