o Most of the County consists of poor hydrogeological conditions for <br />rapid rate disposal systems, such as percolation ponds. <br />o In the past, the County has opposed the use of deep well injection. <br />o Regulatory agencies have taken a position to strongly encourage <br />reuse, particularly in coastal areas such as Indian River County. <br />Additional benefits of using reclaimed water include extension of the service <br />life of the County's existing raw water supply and maximization of existing' <br />water treatment facilities. Reclaimed water also provides an ideal resource for <br />irrigation because it can often contain nutrients that can reduce fertilizer <br />requirements and can generally be supplied to the end user at a more economical <br />rate than potable water (particularly where reverse osmosis treatment is <br />required for potable demands). <br />Identification of large users, such as golf courses, is the first step in <br />developing a reuse system. The County has already taken the initiative on this <br />step by utilizing the Hawk's Nest Golf Course to dispose of reclaimed water from <br />the Central (Gifford) WWTP. The Grand Harbor and Sandridge golf courses are <br />permitted with the Florida Department of Environmental Regulation (FDER) as <br />reclaimed water reuse sites once reclaimed water becomes available from the <br />a <br />Central and North WWTPs, respectively. <br />The Effluent Reuse Capacity Analysis Program (ERCAP) was used as a planning tool <br />to estimate the total Phase I and II reuse demands within the five County <br />service areas. ERCAP was developed by PBSAJ to aid in selecting potential reuse <br />sites and estimating probable reuse capacity. <br />It was determined, based on the ERCAP analysis, that the County has adequate <br />reuse capacity to meet Phase II effluent disposal requirements. Three <br />alternative reuse scenarios were developed that included: <br />o • Irrigating all *potential areas of the County (existing and future <br />single-family, multi -family, and commercial areas; golf courses; and <br />citrus groves). <br />o . Irrigating all potential areas of the County as .described above, <br />with the exception of existing and future single-family residential <br />areas. <br />o Irrigating all potential areas of the County as described above, <br />with the exception of existing single-family residential areas. <br />SEP 71 BE <br />1 8 1990 OOK PAG <br />
