Project Description

Name: Laredo Water Treatment Facility
Location: Larado, TX
Owner: City of Laredo
Architect/Engineer: Carollo Engineers

The only water treatment plant in Laredo, Texas, was built in the middle of the last century. Not surprisingly, dramatic upgrades and capacity expansion were required to accommodate the needs of the rapidly growing city. What’s more, since this was Laredo’s only water treatment facility, it had to remain in service throughout the project. In the end, all key components of the facility have been modernized, successfully expanding capacity to 65 million gallons per day, while ensuring that the plant can operate for many years without additional upgrades or expansions.

A Way Forward

Working with very little documentation of the original 1950s construction, our team completed new installations and modifications to all phases of the plant, including new flocculation basins, larger raw water pipelines and multiple new sand and media filters.


The plant also features a state-of-the-art control system. Operations previously done by hand in the field are now performed from a central control room, allowing the city to cut costs by automating many functions and running more efficiently.

The Power to Deliver

Large backup generators were installed, ensuring continuity of service even in the event of a power failure.
