Luce Bayou Interbasin Transfer Project Construction Photos
Most people have heard about the Coastal Water Authority’s Luce Bayou Interbasin Transfer Project. But few have seen it. Its size makes it impossible to see from the ground. It stretches from the Trinity River to the northeast corner of Lake Houston, where Luce Bayou enters the East Fork. The purpose of the project: to provide additional surface water supplies to end users that utilize water from Lake Houston, especially the new Northeast Water Purification Plant.
Surface Water Capacity to Manage Growth and Fight Subsidence
Studies have shown that Lake Houston and the new plant cannot meet future demand at their current capacity. Transfer of additional raw water supplies to Lake Houston will support future expansion of treatment capacity at the northeast plant and the mandatory conversion from groundwater to surface water to help reduce subsidence.
The City will eventually transport 500 million gallons per day from the Trinity river to Lake Houston through the pipelines and canals you see below.
Connecting Trinity and San Jacinto Watersheds
The Luce Bayou Interbasin Transfer project includes the Capers Ridge Pump Station (CRPS) located on the Trinity River in Liberty County, 3 miles of Dual 96-inch Diameter Pipelines, and 23.5 miles of earthen Canal System. The pipeline will extend west southwest approximately 3 miles along a geological ridge (Capers Ridge). The pipeline will then outfall into the sedimentation basin at the start of the canal. The canal will outfall into the lower reaches of Luce Bayou, which flows into the northeastern corner of Lake Houston.
Originally, engineers considered using a large part of Luce Bayou itself to transport the water and minimize construction costs. However, environmental concerns nixed that idea. Today, they use only the last few hundred yards of Luce Bayou. But the name stuck.
