Project Description:
Description: This project is a Reclaimed Water Seasonal Storage and Alternative Reclaimed Water Supply Feasibility Study. The
study will evaluate the technical, regulatory, and financial feasibility of:
1. Significantly increasing the storage capacity of an existing 17± acre reclaimed water pond by leveling and elevating the perimeter
berm and modifying other pond structures to increase the range of operating water levels by up to 6 feet, and
2.Utilizing existing once-through cooling water currently discharged by others to a nearby canal as a source of additional reclaimed
water supply during times when reclaimed water demand exceeds supply.
The Plant City Water Reclamation Facility (WRF) was expanded and upgraded in 2008 and provides a very reliable source of high
quality reclaimed water. During design, the City chose to re-purpose several existing treatment basins and a treatment pond in the
new treatment scheme. Three oval concrete lined basins are in use for reject storage, and a 17 acre pond formerly used for nutrient
removal is now used for reject and operational storage. An existing pump station is used to return the pond water to the WRF for
retreatment and reuse. The City believes there is potential to significantly increase the storage capacity of the pond and to utilize
the pond as a receiving and storage system for an alternative water supply.
A 1 foot increase in water level in the 17 acre pond can provide over 5 million gallons of additional storage volume. Modest
increases in berm height may be easily achieved but a more ambitious storage volume of 20 to 30 million gallons may be
developed if soil conditions and physical limitations permit, and if other pond modifications can be accomplished. The study will
provide soil investigation, topographic survey, regulatory evaluation, and design services necessary for development of a
preliminary plan. Safety, maintenance, and operability factors will be evaluated and incorporated into the preliminary plan. The
pond is located within a flood plain; the study will estimate the extent of flood plain impacts, if any.
A local industry discharges over 1 million gallons per day of once-through cooling water to the West Canal, which lies adjacent to
the eastern edge of the WRF site. This water is of suitable quality for use as an alternative reclaimed water supply. The preliminary
plan will include modifications to teh existing pump station or installation of a new pump station to recover this water.
