1 Comprehensive Plan Update - Sanitary Sewer Section Planning Commission Workshop: November 10, 2014 Application type Agency Review Comments Applicable Plan Sections Staff Planner Staff Recommendation Publicly initiated Not at this time Sanitary Sewer Section Will Augustine Not at this time Comprehensive Plan Update Sanitary Sewer Section Text Amendment The Sanitary Sewer (SS) Section s overarching intent is to enable the County to effectively provide reliable, efficient, and environmentally safe collection, transmission, treatment, and disposal of all wastewater generated throughout the Unincorporated Hillsborough County Wastewater Service Area. The SS Section has been revised utilizing a content neutral approach to more clearly and concisely articulate three (3) major Objectives to assist in achieving these goals. They are to: SSS Objective 1.1 Develop and maintain a sanitary sewer collection system for all wastewater generated throughout the wastewater service area. SSS Objective 1.2 Develop and maintain an effective sanitary sewer treatment system for all wastewater generated throughout the wastewater service area. SSS Objective 1.3 Develop and maintain a sanitary sewer disposal system for all wastewater generated throughout the wastewater service area. The primary revision to the SS Section is the reorganization and addition of new language that recognizes and provides a framework for the efficient and cost effective collection, treatment and disposal of all wastewater generated throughout the service area. Planning Commission staff has worked in coordination with Public Works Department staff and Development Services Department in the review and updating of the SS Section, previously referred to as the Sanitary Sewerage Element. Through this review process, additional minor revisions are being proposed including the deletion of redundant and obsolete language or statements with no implementation aspects. The format has also been revised in various ways to improve the readability and conciseness of this Section and the Comprehensive Plan as a whole. The main changes include the reorganization of the entire Comprehensive Plan to group Sections/Elements under one of four (4) themed topics: People, Places, Natural Spaces and Governance and Implementation. In addition, Strategies are being proposed as implementing guidelines for certain Polices. The Strategies were generally extrapolated from previous Objective and Policy language. Further, the formatting is intended to streamline the document. This is reflected in the overall size reduction of the Sanitary Sewer Section. As adopted, the Sanitary Sewer Section, previously referred to as the Sanitary Sewerage Element, had one (1) Goal, eight (8) Objectives, and twenty-three (23) Policies. As a result of revising and reorganizing the text, the SS Section was reduced to having one (1) Goal, three (3) Objectives, eleven (11) Policies and 5 Strategies. The Sanitary Sewer Section has been revised to provide an understandable and concise policy framework that identifies the County s Sanitary Sewer efforts and implementation goals. The substance of the Section has been retained, while extraneous and obsolete language has been deleted or revised.

2 PLAN HILLSBOROUGH 2040 COMPREHENSIVE PLAN Sanitary Sewer The purpose of the Hillsborough County Water Services is to provide reliable, efficient, and environmentally safe collection, transmission, treatment, and disposal of all wastewater generated throughout the Unincorporated Hillsborough County Wastewater Service Area. All public and private wastewater treatment plants will provide advanced wastewater treatment (AWT) where technically feasible. Wastewater facilities will be designed and constructed based on a need to maintain the established level of service of 90 gallons/day/person. Usage of existing serviceable facilities will be maximized. Existing treatment facilities will be expanded to their optimal sizes based on cost-effectiveness and site restrictions. The new conveyances and expansions will be constructed in phases, to provide treatment capacity as the demand occurs. Existing conveyance facilities will be expanded and/or new conveyance facilities will be constructed to their optimal sizes based on cost-effectiveness and site restrictions. The expansions will be constructed by development as a condition of development in order to accommodate its wastewater demands. The Sanitary Sewerage Section addresses and directs government activities, and provides guidance to the private sector on how the People, Places, Natural Spaces, Governance and Implementation wastewater needs of all residents within the unincorporated Hillsborough County service area will be met. This is accomplished through planning for the long term wastewater needs of the County, and correcting any existing deficiencies in the system. Within this Element, Hillsborough County addresses its responsibilities for wastewater service within the unincorporated County area. The Sanitary Sewerage Section focuses on the facilities needed by existing residents and the anticipated needs of a growing population in unincorporated Hillsborough County through the year The County s wastewater system is divided into two service areas encompassing approximately 245 square miles: the Northwest Service Area, which is that portion of the County lying north and west of the area served by the City of Tampa wastewater system; the South-Central Service Area, which is that portion of the County lying east of the areas served by the City of Tampa. Both service areas are bounded by the Urban Service Area (USA). The wastewater system currently services more than 125,000 customer accounts for a total 181,750 dwelling units served. The County is currently involved in a construction program aimed at meeting existing commitments within its service areas and providing capacity capable of accommodating growth. Construction of new treatment facilities will be phased to meet future demands based on population trends and projected needs. Construction of new conveyance facilities will be accomplished by the County and developers as a condition of development. Sanitary Sewer Page 1

20 Content Neutral Revision Definitions Advanced Secondary Treatment - Secondary waste treatment plus deep-bed dual media filtration. Advanced Waste Treatment - Wastewater treatment as defined in Chapter , Florida Statutes, or as amended in the future, which will provide a effluent product that a) Contains not more than the following concentrations: Biochemical Oxygen Demand (CBOD5) 5 mg/l Suspended Solids 5 mg/l Total Nitrogen, expressed as N 3 mg/l Total Phosphorus, expressed as P 1 mg/l b) Has received high level disinfection, as defined by rule of the Department of Environmental Protection. BOD - Five-day biochemical oxygen demand is a test performed to determine the amount of oxygen microorganisms would use during decomposition of organic matter. Composting - Present-day composting is the aerobic, thermophilic decomposition of organic wastes to a relatively stable humus. The resulting humus may contain up to 25 percent dead or living organisms and is subject to further, slower decay but should be sufficiently stable not to reheat or cause odor or fly problems. In composting, mixing and aeration are provided to maintain aerobic conditions and permit adequate heat development. The decomposition is done by aerobic organisms, primarily bacteria, actinomycetes and fungi. Conveyance Facilities - All facilities required for the collection, transmission and pumping of wastewater. Deep Bed-Dual Media Filtration - Filtration process that uses a deep bed (4' or greater) composed of two distinctly different granular substances (such as anthracite coal and sand), as opposed to single media filtration. Effluent - Water, after some degree of treatment, flowing out of any treatment device or facility. Force Main - A pressurized transmission pipe which carries wastewater from a pump station to the point of discharge. Gravity Main - A pipe in which wastewater flows by gravity along descending gradients from source to outlet. Industrial Reuse - Consumption of reclaimed water by industrial users for various purposes, such as process, make-up, and feed water. Influent - Wastewater (raw or partially treated) flowing into a treatment process or treatment plant. Land Application - Treated wastewater, sewage sludge, or other products of wastewater treatment applied to land as a method of treatment and/or disposal. Limited Access Irrigation - Irrigation of sod farms, forest, fodder crops, pasture land, and other agricultural uses with limited public access with reclaimed water. Master Pump Station - A major pumping facility which pumps 600,000 gallons per day or more. On-site Sewage Treatment Disposal System (Septic Tank System) - A small localized wastewater treatment system which treats wastewater and disposes of the treated wastewater by subsurface soil absorption or evaporation on the site at which the wastewater is generated. These are typically individual or multi-family septic tank systems and do not include conventional communityoriented wastewater treatment facilities. 14

21 Content Neutral Revision Definitions Permitted Capacity - A facility's operating capacity allowed by the FDEP Operating Permit issued for the facility. Potable Water - Water satisfactory for drinking, culinary, human consumption, and other domestic purposes. Public Access Reuse - Irrigation of lands open to public use, such as golf courses, cemeteries, public parks, landscaped areas, and other areas intended for public access, with reclaimed water. Pump Station - A pumping facility which discharges flow through a force main. Reclaimed Water - A high-quality effluent which has received additional treatment and is of suitable quality for use in wetland systems, turf irrigation, and industrial facilities. Sanitary Sewerage (Wastewater) Facilities - All facilities required for the collection, transmission, treatment, and disposal of wastewater. Secondary Wastewater Treatment - Wastewater treatment that consists of biological conversion of dissolved and suspended organisms into biomass (biological cells) that can subsequently be removed by sedimentation. Effective secondary treatment removes almost all the floating and settleable solids and approximately 90 percent of the suspended solids and organics (as measured by BOD5). Normally, treated effluent from a secondary wastewater treatment facility is disinfected by chlorination prior to final disposal. Septic Tank System (On-site Sewage Treatment Disposal System) An on-site sewage treatment disposal system for individual homes, multifamily residences, and commercial property where municipal wastewater service is unavailable. The system consists of two major components, a septic tank and a subsurface wastewater exfiltration system (SWES). The septic tank is an underground tank that provides primary wastewater treatment that consists of the removal of settleable and floatable solids. The clarified effluent from the septic tank flows to the SWES where it receives physical, chemical, and biological treatment as it percolates through the unsaturated soil to the groundwater. Sewage Sludge - The accumulated solids separated from liquids during wastewater treatment processing. Wastewater, Domestic or Sanitary - A combination of the liquid and water-carried wastes from dwellings, commercial buildings, industries, institutions, and the like together with any groundwater, surface water, and storm water from inflow and/or infiltration; originating as wastes from kitchens, water closets, lavatories, bathrooms, and showers; the strength of which normally fall below the following parameters: biochemical oxygen demand (BOD5) (300 mg/l); total suspended solids (TSS) (300 mg/l); total nitrogen (TN) (40 mg/l), and total phosphates (TP) (12 mg/l). 15
