Specifications include, but are not limited to: 1. Conduct a data validation of six or more water utilities of varying size (<10,000; 10,000- 49,999; and 50,000-100,000 population). The TWDB will work with the Contractor to identify potential retail public water utilities interested in participating in the study. These utilities will need to be comfortable sharing their water loss audit process, data and records and describe how they historically utilized the audits in addressing water loss. 2. Work with TWDB staff in drafting validation questions based on industry standards and the TWDB’s online reporting application format. These questions should be able to be used in future self and third-party validation efforts. 3. The contractor will review the current and past water loss data submitted by the utilities in order to understand each utility’s data gathering process.
