Comprehensive Plan <br />Public Treatment Plants <br />Sanitary Sewer Sub -Element <br />Besides producing high quality effluent, all public treatment plants currently have more than <br />enough capacity to accommodate existing demand. The following sections discuss the county's <br />future wastewater treatment needs and alternatives to meet those needs. <br />Projection of Future Demand <br />Assumptions <br />The comprehensive planning process is an opportunity for the county to complete an assessment <br />of its long range sanitary sewer needs. Such a needs assessment must consist of an analysis that <br />is more than a straight line linear projection. Future projections should utilize certain <br />assumptions based on past trends, present conditions, and future desires. The main assumptions <br />utilized in the sanitary sewer needs assessment are as follows: <br />• The county will be the primary provider of sanitary sewer collection, treatment, and <br />disposal; <br />• The City of Vero Beach will continue to serve the City of Vero Beach, the Town of <br />Indian River Shores and a portion of the unincorporated county; and <br />90% to 95% of future new development will connect to the regional sewer system. <br />The county will continue to maintain these policies and evaluate the feasibility of regional <br />system versus package treatment plants for the above referenced type of developments. <br />The existing conditions section of this sub -element provides a discussion of the existing capacity <br />of centralized wastewater treatment facilities, with an emphasis on the county system. That <br />discussion addresses the supply side of the wastewater treatment system. This section considers <br />the demand side. <br />The information for this section is based on the permanent and functional population projections <br />contained in the Introductory Element and on the projected land use patterns contained in the <br />Future Land Use Element. That information is also consistent with the county utilities master <br />plan. To develop these projections, the county used data such as historic growth, population <br />estimates, number and type of dwelling units, and developed commercial/industrial acreage. <br />As with other facility analyses, planning for wastewater treatment facility expansion requires a <br />rational approach to projecting growth over a finite planning period.
