Idledale Water and Sanitation District

TZA Water Engineers has been working with the Idledale Water & Sanitation District (District) since 2012 supporting its water rights decrees and drinking water well operations. Since 2015, TZA has been working closely with the District’s management and operations personnel to address a long standing radiological compliance matter. Another engineer had previously recommended a costly capital improvement project to reduce the presence of certain radiological parameters in the District’s drinking water. In addition to the costly capital components, the District customers’ water rates would also have been increased considerably largely due to expensive radiological waste management and disposal requirements.

In October of 2016, the Water Quality Control Division approved TZA’s alternative plan to provide for blending for regulatory compliance. In doing so, the upgraded system will consist of:

  • Well No. 1A and Well No. 1B located at the Upper Grapevine Road Water Treatment Plant where sodium hypochlorite treatment will occur. Both wells have been evaluated, rehabilitated, and equipped with new pumping equipment.
  • Upper Storage Tank improvements, including modification of yard piping, to account for chlorine contact time.
  • Reactivation of Well No. 3 and modifications to the Forks Building Treatment Plant as a blending facility, including sodium hypochlorite treatment prior to redistribution.
  • Due to the regulatory review and approval timing, construction of the improvements began in the fall of 2016 and are scheduled to be completed in the spring of 2017 at a construction cost of approximately $100,000.
  • TZA is supporting the construction phase through periodic progress meetings and equipment and materials procurement support.
