3 Edwards Aquifer Compliance Years 06/07 Future Total - 1,400 1,400 1,400 1,400 1,400 1,800-8,800 This project includes testing and remediation projects. The testing of the wastewater collection system is mandated by the Texas Commission on Environmental Quality (TCEQ) Edward's Aquifer rules. The City began this program in Remediation projects encompass the completion of the collection system repairs identified by the testing program. These repairs include collection main repair / replacement, etc. Completion of repairs must be done within 1 year of identification. This is an on-going mandated requirement. Funding in 2011/12 increases due to implementation costs being spread out over a shorter period of time. Construction 7,650 Design 1,150 Total $8,800 Funded with cash from operations. Possible operational savings due to reduced - (15) (15) (15) (15) inflow and infiltration 16

4 Wastewater Line Upgrades Years 06/07 Future Total Project entails replacement of wastewater lines in the service area to improve flow and eliminate aged, undersized lines. Replacement of lines is coordinated with the Street Department CIP program to replace wastewater lines prior to or during street rehabilitation to minimize the impact of maintenance on upgraded streets. EARZ rehabilitation and the demand on the budget leave only a small amount of funds to be set aside for projects that have not specifically been identified. Construction 430 Design 70 Total $500 Funded with cash from operations. Location to be determined Maintenance (savings) - (2) (2) (2) (2) 17

5 2005 Annexations Years 06/07 Future Total In December 2005, the City annexed over five thousand acres into the City limits. Included in this annexation was area 16a, which runs along northeast Inner Loop. This project will extend service to ares 13a, 13b, 13c and 16a. Construction 860 Design 130 Total $990 Funded with utility revenue debt. Area a Area b Area c Area a Increase operation and maintence costs

6 Cimarron Hills WWTP Years 06/07 Future Total , ,085 This project will expand the capacity of the Cimarron Hills Wasatewater Treatment Plant from 200,000 gallons per day to 450,000 gallons per day. The expansion of plant capacity includes the construction of an additional effluent holding pond and pumping infrastructure to transfer effluent from the new pond to the effluent holding pond on the Cimarron Hills Golf Course. The 2007/08 budget includes design and permitting costs. The entire cost of permitting, design and construction, once paid by the City, is to be reimbursed by the developer of the Oaks at San Gabriel subdivision. Construction 1,770 Design 265 Other 50 Total $2,085 Design: 2007/08 Bid: 2008/09 Construction: 2008/09 Developer contributions Plant operating costs (treatment and electrical)

7 Lift Station Decommissioning Years 06/07 Future Total This project will decommision the River Down and River Ridge lift stations. The flow will be redirected to the new South Fork Wastewater Interceptor. River Ridge Lift is the most critical need due to proximity to the San Gabriel River, difficult access and a lack of a backup generator. Construction 500 Design 80 Total $580 Project Schedule 07/08: Funded with cash from operations. River Down Lift Stations River Ridge Lift Stations Electrical Cost Savings - (3) (3) (3) (3) 20

8 Smith Branch / San Gabriel Interconnect Years 06/07 Future Total , ,720 This project will construct a new 42" gravity interceptor from the existing Smith Branch Lift Station on State Highway (SH) 29 to a new San Gabriel Lift Station, which will be located midway between SH 29 and SH 130 on Smith Branch. Additional improvements include a force main from the new San Gabriel Lift Station to the San Gabriel Treatment Plant attenuation unit, designed to pump to both the San Gabriel and Pecan Branch Wastewater Treatment Plants. Construction 4,900 Design 820 Total $5,720 Design: Underway Bid: Fall 2007 Construction: Spring 2008 Funded with cash from operations, impact fees and utility revenue debt. Increased electrical costs

9 Park Lift Station Upgarde Years 06/07 Future Total This project will upgrade the Park Lift Station. Upgrades include repair of the rails, the installation of a backup generator and the installation of a fence around the lift station. Construction 220 Design 30 Total $250 Funded with cash from operations. 22

10 South Fork Interceptor Phase 2 Years 06/07 Future Total - - 1, ,700 This project is for City cost participation in the construction of the wastewater South Fork interceptor from the western boundry of the Wolf Ranch shopping center to the western boundry of the Water Oaks subdivision in Southwest Georgetown. Project is for the differential cost oversizing the line needed to serve the Georgetown service area versus the line size needed to serve the Water Oaks subdivision. Project may be implemented in phases with some costs payable in 2007/08 and the remainder of the costs in 2008/09. Construction 1,480 Design 220 Total $1,700 Funded with a portion of South Fork impact fees, developer contributions and utility revenue debt. Increase operation and maintenance costs

11 Sun City Lift Station Upgrade Years 06/07 Future Total Install electrical MCC and controls for two additional higher capacity pumps. Repair the lift station's wetwell. Purchase and install two higher capacity pumps. Resulting lift station will have one wetwell with two original capacity pumps and one wetwell with two high capacity pumps. Total capacity will allow full buildout of the proposed service area for the lift station. Construction 430 Design 70 Total $500 Funded with cash from Special Improvement Project (SIP) fees. Increased pumping costs

12 Master Plan Update Years 06/07 Future Total Updates the Water System Master Plan as part of an update to the impact fee study planned for Construction - Design - Other 75 Total $75 Bid: N/A Construction: N/A Funded by cash from operations. 25
