City Manager Approval — August 29, 2008
Action authorizing the City Manager to execute Change Order No. 3 with Enviro
Remediation Coatings Services, Inc. for the 2005-2006 Wastewater Collection
System Rehabilitation Project.
Department: Water and Wastewater Utilities
Staff Person: Michael D. Thane, P.E., Director of Utilities
Justification:
The City is required to inspect, repair, and certify the wastewater collection system in
compliance with the Texas Commission on Environmental Quality's Edwards Aquifer Recharge
Zone Protection Program. This change order adjusts final contract quantities and contract time
for all work performed under this contract. Contract time is being increased by 90 days to
account for delays caused by increased rock excavation, and changing the method of 12 -inch
pipe installation from directional drilling to open cut.

Background Information:
This project rehabilitates the defective wastewater collection system, which was identified in the 2005-
2006 Wastewater Collection System Inspection Project, in three Edwards Aquifer Basins (CC -32Z, OC -
30Z, and BC -22Z). The elimination of defects helps protect the aquifer and reduces inflow and
infiltration entering the sewer system, thereby reducing the City's treatment cost. The scope of the
project includes cured -in-place pipe, liner patches, point repairs, pipe bursting, boring, conventional pipe
replacement, internal joint grouting, and manhole rehabilitation and replacement.
