Ferrovial bags water treatment contracts worth £221m in Texas, US


July 09, 2019 – PLW Waterworks, owned by Ferrovial Agroman subsidiaries Webber and Cadagua, has won contracts worth €274m (£221.2) to upgrade two water treatment plants in Texas, US.

The first order, valued at €169m (£151.3 m), is for the $1.4bn (£1.1bn) expansion of Houston’s Northeast Water Purification Plant, which is expected to serve more than two million people.

The design-build expansion project will add 320 million gallons per day (mgd) to the existing water plant’s capacity to allow the City and the regional water authorities to meet projected demands.

The project includes the design, construction and commissioning of intake pump station; twin 108-inch transmission mains; pre- and post-treatment chemical addition; flocculation/sedimentation basins; ozone treatment; filtration; finished water storage tanks; and high service pumping station.

Under the terms of the contract, PLW Waterworks will be responsible for installation of more than 37,000m of underground pipelines and construction of a new treated water pumping station, with a daily capacity of 1.21m m³.

Work on this contract is planned to be completed in 2024.


Under the second contract, PLW Waterworks will build a $120m (£95.7m) surface water treatment plant in the city of Pearland, south of Houston.

The firm will be responsible for executing pre-sedimentation and processing facilities, pumping stations and pipelines.

Upon completion in 2023, the surface water treatment plant is expected to serve a population of 75,000.


The surface water plant project forms part of the Capital Improvement Program and is also part of the City Council’s focus on its Sustainable Infrastructure & Healthy Economy Strategic Priorities.

Aimed to provide reliable source of clean drinking water for the residents of Pearland, the project is backed by funding through a Drinking Water State Revolving Fund low-interest loan administered through the Texas Water Development Board.

In 2016, Ferrovial, through Webber, had acquired Pepper Lawson to expand its water business in the US.
