City of Leander Kauffman Loop Elevated Storage Tank

Designing sky-high water solutions for the City of Leander

Project Purpose

As the rapidly growing City of Leander expands further north and east, a new 1200 pressure plane was required to serve the area, resulting in the need for additional elevated storage. Based on updates to the City’s water model and growth projections, a new 1.25 MG elevated storage tank (EST) was selected to meet this need. The project included a site development design with paving, grading, fencing, and drainage improvements.

Project Approach

KFA was retained by the City of Leander to plan, design, and provide construction administration for the EST design. KFA updated the City’s system-wide water models in WaterCAD to determine the required size and elevation for the proposed EST. After reviewing the project parameters, a composite EST (concrete pedestal with steel tank) was recommended as the best application for the project. Surveying, geotechnical investigations, environmental, and archaeological investigations were completed.

Because the selected site was located in the Edwards Aquifer Recharge Zone, KFA prepared a Water Pollution Abatement Plan as required per the Texas Commission on Environmental Quality (TCEQ). KFA designed drainage improvements to direct and detain stormwater and water from the EST overflow. Additionally, the soils underlaying the site were found to contain voids, requiring the EST foundation design to include drilled shaft piers.

The KFA team prepared the final design and construction documents for the EST, including offsite piping modifications, site grading, pavement design, and drainage improvements. After discussing with the City, the use of a 100% solids elastomeric coating on the interior of the tank was selected for its longer life and ease of maintenance. The project was permitted with both the City and the TCEQ. The KFA team assisted the City with bidding, construction administration, and onsite inspection services.

Project Results

Completed in 2018, this project currently serves the City of Leander by providing necessary water storage.
