Recommendation
Fund as a Medium priority. The project is to add 3 billion gallons of storage to the Regional Reservoir during the renovation and will
add system reliability and approximately 3 mgd of additional water supply at a cost of $66,403,040. The additional capacity is
anticipated to be needed in the future. The cost of developing 3 mgd of water supply would be expected to cost up to $45 million,
based on the average cost of other existing and planned regional scale water supply projects that the District has previously
funded. Therefore, staff recommends considering funding the reservoir expansion at up to half of $45 million or $22.5 million (see
the Costs section below for further details). There was sufficient information provided to evaluate the project and the cooperator
has confirmed the necessary matching funds will be requested in their next budget cycle. This project is within the District's
statutory authority to fund and is not the result of a permit requirement or enforcement action.
Description
This alternative water supply project will add 3 billion gallons of additional storage to the Regional Reservoir during the renovation
process. The reservoir came on line in 2005, and in 2006 cracks began to appear. In order to properly function, extensive repairs
are necessary. TBWs Board of Directors approved a contract with Kiewit Infrastructure South to renovate the reservoir and to
increase the storage by 3 billion gallons. The additional storage will ensure reliable, sustainable and drought resistant systems,
maximizing alternative supplies to the greatest extent possible. Expanding the existing reservoir will cost hundreds of millions of
dollars less than building a new reservoir.
Benefits
TBWs analysis concludes that 3 mgd of additional water supply can be made available without the need for other new
infrastructure, and that up to 15 mgd can be supplied during drought conditions reducing the potential of exceeding groundwater
permit limits during droughts.
Costs
TBWs application states that the reservoir expansion costs are anticipated to be $66,403,040. As such, the District was requested
to fund 50 percent, or $33,201,520. The renovation and expansion work will be done concurrently and it is anticipated that
separating costs from one another will be difficult. Should the Governing Board choose to fund the project, staff recommends
basing funding on the costs associated with previous District projects and planned future project costs found in cooperators' water
supply plans, and the District's Regional Water Supply Plan. These alternative water supply supply projects cost approximately
$15,000,000 per 1 mgd to develop. Therefore, the recommended cost would be $45,000,000, with the District contributing
$11,250,000 each in FY2013 and FY2014, for a total of $22,500,000.
