The City is required to continue our Wastewater Collection System Rehabilitation program in
order to comply with the Texas Commission on Environmental Quality's (TCEQ) Edwards
Aquifer Recharge Zone Protection Program which requires that wastewater collection systems
located over the Edwards Aquifer be inspected and rehabilitated every five years. The
elimination of defects will not only help to protect the Edwards Aquifer, but will also reduce
inflow and infiltration entering the City's wastewater collection system, thereby reducing the
City's treatment cost. The City has completed the inspection of 12 sub -basins to determine
areas that require rehabilitation for this project.
The work being performed under this contract includes sub -basins BC -01, BC20-Z, CC32-Z,
CC34-Z, CC35-Z, CC37-Z, LC09-Z, LC15-Z, LC16-Z, LC17-Z, LCI 8-Z & LC19-Z. The project
includes 2,450 LF of new 8 -inch through 10 -inch pipe installed by pipe bursting, 2,650 LF of
8 -inch through 42 -inch CIPP liner, and construction of six manholes.
