Department: Utilities Administration Staff Person: Michael Thane, P.E., Director of Utilities Justification: The City is required to inspect, repair, and certify its wastewater collection system in compliance with the Texas Commission on Environmental Quality's Edwards Aquifer Recharge Zone Protection Program. This is the final change order on this project which adjusts final quantities, and accounts for all as -built quantities for this project. Funding: Cost: $9,055.53 Source of funds: WW Utility Fund (F260) Outside Resources: RJN Group, Inc. (Engineering Consultant) Lower Colorado River Authority (LCRA) Background Information: The project is rehabilitating defective sewers determined from the 2004-2005 Wastewater Collection System Inspection Project in three Edwards Aquifer Basins (EW01-Z, CC -37Z, and OC -28Z). The elimination of defects not only helps protect the aquifer, but also reduces inflow and infiltration entering the sewer system, thereby reducing the City's treatment cost from the LCRA and BRA, who respectively own and operate the Brushy Creek Regional Wastewater Treatment Plant. The scope of the project includes cured -in-place pipe, liner patches, point repairs, pipe bursting and conventional line replacement, directional drilling, internal joint grouting, and manhole rehabilitation and replacement.
