Title
Consider and take action on a resolution authorizing an agreement with Utilis Inc. for Satellite Imagery Leak Detection Analysis and follow-up Acoustic Detection in an amount not to exceed $187,000 (Director of Public Works)
Background:
Approval of this resolution will authorize an agreement with Utilis Inc. for satellite imagery leak detention analysis and follow-up acoustic detection in an amount not to exceed $187,000.
The implementation of this new program will provide data which will help identify water leaks that otherwise would go undetected for long periods of time, contributing to Unavoidable Real Water Loss.
The water leak detection method selected is an innovative technology that utilizes propriety satellite imagery to scan broad areas of concern. Satellites orbiting the earth will be utilized to perform multiple scans of the 54 square mile boundary of League City to detect treated drinking water leaking from urban distribution and transmission network piping. Further details available in the Utilis Satellite Case Study, which is attached. The advantages of the proposed method over traditional leak detection technologies is the satellite imagery’s ability to narrow down areas of concern. This allows “boots on the ground” and associated resources to be focused on the most productive potential leak locations, thus creating an opportunity for substantial savings in the most labor-intensive step (acoustic ground detection) in successful leak detection. The following cities; San Antonio, Austin, and New Braunfels are currently utilizing this technology in their on-going leak detection programs. Water leak detection is considered a "Best Practice" according to the Texas Water Development Board’s list of Best Practices, to help the City reduce annual water loss revenue.
The City’s 2019 revised Water Conservation Plan identified a five-year history of unavoidable real water loss totals ranging from nine (9) percent to near 15 percent. The goal...
