AGENDA MEMORANDUM
Meeting Date: August 11, 2008
From: Raymond S. Sharp, Director Environmental Services/Public Works
Subject: Resolution authorizing Task Order # 33 to Boyle Engineering Corporation for Design of Improvements to the Highland Lakes Water Treatment Plant
Staff Recommendation:
Staff recommends approval of Task Order # 33 to Boyle Engineering Corporation for Design and Permitting and Construction Phase Services Associated with Improvements to the Highland Lakes Water Treatment Plant for $253,108.00.
Analysis:
The Highland Lakes Water Treatment Plant requires substantial improvements in order to meet the regulatory requirements for plant capacity and our own requirements for level of service. The first of the required improvements, a new production well, was installed several years ago to meet the most urgent need. Since then, the City has completed a Water Master Plan study for the Southwest Service Area, and has further evaluated the ability of the plant to provide improved service to existing customers, as well as the possibility of expanding its service area to improve service to our customers in Legacy and Arlington Ridge.
At present, water service to the latter is supplied by the Main Water Treatment Plant on 5th Street, through a 10” diameter potable water main. The 10” main is no longer able to provide adequate service, given present-day demands. Engineering analysis of service areas in the master plan, and further analysis of demands and service areas show that immediate improvements are necessary to meet the needs of our current customers. Further, the Highland Lakes Water Treatment Plant can meet the requirements of an expanded service very economically, compared to other options. The preliminary engineering estimate of costs of improvements to the Highland Lakes plant is approximately $1.4 million, compared to approximately $9.0 million for improvements that would otherwise be necessary.
The improvements will consist of a high-service pumping station and a one million gallon ground storage tank. This will dramatically improve water pressure throughout the service area for existing customers and will provide sufficient plant capacity to be able to expand the service area to include Legacy and Arlington Ridge, who will also enjoy much increased water pressure. Provisions will be made for future additional high-service pumping capacity, an additional one million gallon ground storage tank and for a future well, when further expansion of plant capacity becomes necessary. These improvements will also include an emergency generator and SCADA system improvements for control and monitoring. At completion, these improvements will allow the existing 10” main to be isolated from the new service area, thus making its capacity available to serve a limited amount of new development.
These improvements will address existing capacity and service issues, significantly improve service to existing customers, and free up some existing transmission capacity for future development.
Options:
1. Authorize the Mayor and City Clerk to execute Task Order Number 33 to Boyle Engineering Corporation for $253,108.00; or,
2. Such alternative action as the Commission may deem appropriate
Fiscal Impact:
The 2007 Bond Issue provided funding for SW area booster pump station and improvements to the potable water system in this service area. The cost of this Task Order and the cost of construction are expected to be covered by the bond issue proceeds. Operationally, the Water Fund will see an increase in electric costs because of the addition of the high-service pumps, and some modest increase in chemical costs because of an enlarged service area. Both of these will be offset to some extent by reductions in high-service pumping and chemical costs at the Main Water Treatment Plant when the demands of Legacy and Arlington Ridge customers are converted to Highland Lakes. Being able to make additional transmission capacity available to new development will generate impact fee income and revenues from water sales as connections to the water system occur.
