Arup has been appointed to help develop a new water source for Metro Manila that will pave the way to addressing the water woes of the metropolis – one of the most densely populated urban areas in the world.

Currently fed by the Angat, Ipo and La Mesa Dams, drought conditions across the region combined with a growing population have led to difficulties in meeting water needs. As a result, residents have experienced supply issues ranging from low pressure to no water at all.

To help provide a reliable supply for the ever-expanding population, a new water source, the Upper Wawa Dam, is being developed.

It is planned that the system will be able to start supplying water to Metro Manila on or before December 31, 2021 with an initial capacity of 80 million litres per day (MLD). On or before December 31, 2025, the dam should be able to provide a reliable water supply of 518 MLD, which is sufficient to cater for around three million people.

Acting as the owner’s engineer to the project developer, WawaJVCo, Arup will provide technical support during the bidding period and then oversee the implementation of the two main contracts. We will deliver design review services, site supervision and contract management works.

We look forward to closely working with the team at Arup to deliver this project of critical importance to the East Zone consumers of Metro Manila. The Upper Wawa Dam will be the largest privately-owned bulk water supply infrastructure in the country. ” Guillaume Lucci President, Prime Infra (parent of WawaJVCo)

We have been involved in a number of major water projects in the Philippines, from fresh water supply to wastewater treatment and sewerage. With this landmark development, we are delighted to be able to work with WawaJVCo to support the delivery of a new water source, a fundamental part enhancing the water resilience of Metro Manila. ” Adrian Marsden Adrian Marsden Associate Director
