Arup to help boost Manila's water supply

18 May Arup is to help develop a new dam to address water shortages in the metropolis of Manila in the Philippines.

The existing Wawa Dam over the Marikina River is downstream of the future Upper Wawa dam.

Metro Manila - one of the most densely populated urban areas in the world – is currently fed by the Angat, Ipo and La Mesa Dams. However, 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.

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

It is planned that the system will be able to start supplying water to Metro Manila on or before 31st December 2021 with an initial capacity of 80 million litres per day (MLD). On or before 31st December 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.

Arup, acting as the owner’s engineer to project developer WawaJVCo, will provide technical support during the bidding period and then oversee the implementation of the two main contracts. It 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,” said Guillaume Lucci, president of  WawaJVCo’s parent company Prime Infra. “The Upper Wawa Dam will be the largest privately-owned bulk water supply infrastructure in the country.”

Arup associate director Adrian Marsden added: “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.”
