Description
This project consists of the design and construction of a supplemental reclaimed water supply well and the
modification of the intake structure at the onsite reuse pond at the Englewood WRF to provide additional dry weather
irrigation supplies. Reclaimed water is produced at the Englewood WRF, which serves portions of Charlotte and
Sarasota counties. Current reclaimed water storage includes a 1 MG above ground storage tank, wet weather storage
ponds (onsite and offsite), and a fully permitted ASR system. The ASR well provides 0.5 mgd of reclaimed water
during peak demand periods and has become a critical component of the reuse system. Without previous SWFWMD
funding assistance for the ASR program, EWD reuse would not be as efficient and connection of many current
customers would not have been possible. Installing an additional supply well into the ASR storage zone will increase
the rate at which stored water can be recovered during peak demand. A well approximately 600 feet in depth is
required, along with a pump and appurtenances to produce an additional 0.5 mgd, or about 15 mg of water during
each peak month used. Re-engineering the onsite wet weather pond will more effectively utilize available storage and
freshwater in the surficial aquifer at the WRF. Lowering the pump intake from the existing pond will provide additional
water for irrigation. Reuse demands during dry weather periods often exceed the available supply. This project will
provide additional reuse supply to existing customers during peak demand periods. These customers include Lemon
Bay Golf, Oyster Creek Golf, and Rotunda West Utilities in Charlotte County and Myakka Pines Golf, Englewood
Sports Park, Boca Royale Golf, and Gran Paradiso Subdivision in Sarasota County.
Benefits
The project will provide approximately 82,192 gpd of additional reuse supply that will be used evenly between the
identified customers in Charlotte and Sarasota Counties. This project will offset approximately 61,644 gpd. The
cost/benefit ratio for the total estimated project cost of $260,000 averaging 61,644 gpd using an 8% annual interest
rate amortized over 30 years is $1.02/1000 gallons.
Costs
The total cost of the project is estimated at $260,000. Since the benefits are evenly split between customers in the
Peace and Manasota Basins, EWD is requesting $65,000 from each Basin Board for a total of $130,000 (50%) in
FY2010 funding. Design costs are estimated at $60,000 and construction at $200,000.
Additional Information
Without previous SWFWMD funding assistance for the ASR program, EWD reuse would not be as efficient and
connection of many current customers would not have been possible. This project will further increase this efficiency
and help EWD meet existing contracted amounts. EWD won the 2008 FWEA David York Award for small facilities (<
5 mgd), another example of the benefits that the previous funding assistance has had. Reuse demands during dry
weather periods often exceed the available supply. Additional reuse customers have been identified but the ability to
serve these users during peak demand periods will be problematic without additional supplemental sources. With the
lack of available fresh groundwater or surface water EWD is faced with developing alternative supplemental sources.
Supplemental sources currently identified include the following: Installing an additional supply well into the ASR
storage zone to increase the rate at which stored water can be recovered. A well approximately 600 feet in depth is
required, along with a pump and appurtenances to produce an additional 0.5 mgd, or about 15 mg of water during
each peak month used. Re-engineering the onsite wet weather pond to more effectively utilize available storage and
freshwater in the surficial aquifer at the WRF. Lowering the pump intake from the existing pond will provide additional
water for golf course irrigation to Lemon Bay Golf Course, and may allow EWD to add other golf course storage ponds
to be supplied from this pond. EWD advertises and helps enforce the District's watering restrictions, aids in
xeriscaping education, and have imposed a steep graduated rate structure to discourage high water usage. The EWD
has a policy requiring any new significant development desiring utilities to include a reclaimed water irrigation system
in its infrastructure. EWD's reuse customers are conservation minded and only use the water deemed necessary to
adequately maintain the irrigated area.
