It is the policy of Terrell Water Utilities to allow a concealed leakage adjustment once in a twelve month period for an account, upon presentation of plumber's bill or other documentation to show that a leak was present and has been repaired. The documentation must show date of the repair in order to know what bills were affected by the leak. This adjustment can be up to one-half the leakage up to one-half of a single monthly bill. We will review the usage during the same time period the previous year and determine how much leakage is involved. Water loss due to pranksters, vandalism, etc., does not fall into this category due to no assurance that the circumstances will not reoccur and the limited control of each customer preventing such an occurrence.
