City of Lubbock Lake Alan Henry Water Treatment Plant
As part of the Lake Alan Henry Water Supply Project, Parkhill provided the architectural, mechanical, and structural design for a state-of-the-art water treatment plant. The plant’s raw water screening structure, with 27-foot tall cast-in-place concrete walls, features multi-tiered chambers to precisely control water flow from the Terminal Storage Reservoir.

Strength in Design
The flow control building, with tilt-up concrete walls and a steel joist roof, efficiently manages water distribution. The main building complex is a hub of innovation, housing the membrane filter room, a chemical feed area, and a flocculation/sedimentation basin.
Efficient Flow
The filter room, enclosed by 41-foot tall concrete walls, is equipped with a bridge crane for maintenance, while the chemical feed area utilizes a robust two-level cast-in-place structure. The adjoining sedimentation basin, with 20-foot tilt-up walls supporting a roof, ensures seamless water purification.


Innovation Meets Precision
Parkhill’s design also includes a 5,000 SF high service pump station, featuring a steel frame supporting a 7.5-ton bridge crane and a 10-foot deep pipe gallery. Additional structures, like the reclaimed water basin and thickening basin, highlight the precision and scale of the project. This facility exemplifies engineering excellence and ensures a reliable water supply for the region.
