Surface Water Transmission Program

Houston, TX

Since 1985, LAN has provided planning, design, and Program Management services for distributing the increased capacity of water from Houston’s primary surface water purification plant, as Houston converts from groundwater to surface water to reduce the effects of subsidence.

The $400 million Program provides for more than 250 miles of transmission and distribution mains up to 108-inches in diameter. As part of this program, LAN has managed, designed, and coordinated more than 100 engineering design projects including water system analysis and design, water treatment facility and pump station design, ground storage and well system design, open cut, tunneling, aerial pipe crossings, railroad crossings, waterline rehabilitation using trenchless technology, and the construction management for each project. The City of Houston estimates LAN’s involvement has saved $40 million to date.
