San Roque Multipurpose Project

"Bringing multiple benefits to the Philippines"

What's the best way to provide the Philippines' most densely populated island with badly needed electrical power and irrigation water for the country's primary agricultural product?

MWH has been tackling this challenge on the San Roque Multipurpose Project (SRMP) for San Roque Power Corporation (SRPC) in the Philippines. When completed in late 2002, SRMP will be the world's largest privately built hydroelectric project.

The dam will stand more than 200 meters high, with a crest length spanning 1.1 kilometers, and will contain more than 38 million cubic meters of materials. The spillway has six large gates, each measuring 15 meters wide and 19 meters high. The powerhouse contains three 115 MW Francis units for a total capacity of 345 MW.

Providing Much Needed Services

For the past four years, MWH engineers have closely worked on many aspects of this world-class project - from the dam and powerhouse to the spillway and tunnels. As a global leader in hydropower engineering, we have served as the Owner's Engineer to review all off-site and on-site activities of the EPC contractor for the US $1.2 billion San Roque multipurpose project.

Although the project was first conceived nearly 30 years ago, the San Roque project was approved by the Philippine government in 1997 for fast-track construction on a private "engineer-procure-construct" basis. MWH is providing off-site engineering review during the project's design and construction phases, as well as on-site quality assurance services, including construction monitoring and commissioning activities.

The multipurpose facility will provide residents of Luzon, the Philippines' most populated island, with 345 megawatts of badly needed "peak-period" electrical power, as well as flood control, water quality improvements and downstream irrigation for the country's leading agricultural product - rice.
