Project Description:
The City of Dunedin supplies reclaimed water, as an alternate to the use of groundwater, for landscape irrigation by 3,464
commercial and residential customers. The City carefully monitors reclaimed water use and augments reclaimed water supplies
during the high irrigation demand times experienced in late Spring and early Summer. Even with careful monitoring, it is obvious
that additional reclaimed water storage is required to better balance the differences between wastewater flow rates and irrigation
water demands. The City seeks to expand the reclaimed water storage capacity available to reach a more near "zero" discharge
condition during the April/May time frame of low wastewater flows/high reclaimed demand periods. The construction of additional
storage capacity would also allow the City to extend reclaimed water service to additional customers for increased reuse throughout
the year.
The City owns property referred to as the San Christopher Drive site. This site is presently the location of an old 0.5 MG elevated,
steel water storage tank. The existing tank was an early element of the City's potable water supply. Over time, it became too low
and too small to be useful for potable water supply. It was converted for reclaimed water supplyas one of the City's initial stages of
system operation. Although the existing tank is used for limited reclaimed water storage, its low elevation and increasing age cause
it to have limited value to the City's expanded reclaimed water system. Demolition of the existing 0.5 MG tank and construction of
two new 1.0 MG, ground level, circular, prestressed concrete storage tanks would make better use of the available San Christopher
Drive site and result in an ability to achieve near "zero" discharge for extended periods of time with less reliance on groundwater
augmentation and increased service to a larger number of customers. Using conditions experienced in April and May 2012 for
illustration, the construction of two, new 1.0 MG storage tanks, would have resulted in zero discharge for 14 days in May while
allowing the connnection of an additional 360 to 400 residential customers. Recognizing the benefits of increased storage, the City
has programmed demolition of the existing, aging elevated tank and construction of the new 2.0 MG capacity tanks in FY2014. The
City requests SWFWMD funding assistance thru its Cooperative Grant Program. With grant funding, the City can complete the
project on the basis of in-house design and competitve bidding for project construction in FY2014.

Since 1992, the City of Dunedin has continued its efforts to optimize the reuse of its reclaimed water supplies and to reduce the use
of groundwater for landscape irrigation. The City initially relied on the conversion of two (a 0.5 mg and a 1.0mg) older (late 60's)
elevated steel water tanks for reclaimed water storage. The City has since constructed several, prestressed concrete, ground
storage tanks to respond to the systems increased customer demands and to reduce the quantity of reclaimed water discharged
into St Joseph Sound. The City continues use of the aging elevated tanks but realizes that, especially the 0.5 mg tank, have
