A. GENERAL DESIGN REQUIREMENTS
Prior to beginning design work on a project, the EOR shall arrange a pre-engineering meeting with Seacoast staff to determine feasibility, master plan ramifications and any other special project requirements. The EOR shall comply with the following prior to making a utility construction plan submittal to Authority:
1. Master Plan/Main Extensions Required
a. Engineering design for all new projects will be evaluated by Authority staff for conformance with the most current Authority approved Master Plan. In areas where master plan facilities have not been constructed, the Developer will incorporate the design and construction of these facilities in the overall design of the project.
b. Developer/Property Owner shall extend water and sewer mains to the project boundaries most remote from the current system terminus, or to a point which best facilitates service to properties as yet unconnected. The specific size and location of service extensions shall be determined by Authority. Individual residential lot owners requesting water or sewer service shall be required to extend water and sewer mains based on the developer criteria set forth above. The use of long service lines to avoid extending mains is prohibited. In instances where the residential property to be served is a corner lot and water and/or sewer lines of adequate size are located in a public road right of way or easement adjacent to a property line of that lot, service line connections to the existing mains will be permitted.
2. Piping Orientation
All water, sewer and reclaimed water facilities shall be designed in accordance with these specifications. To the greatest extent possible, all water mains shall be designed to cross over all other pipelines i.e.: storm drainage, gas, sanitary sewer and force mains. Water mains crossing under the above referenced mains will warrant special design consideration based on actual circumstances. Force mains must be designed to be full of liquid under all operating conditions to avoid areas of gas accumulation. Special corrosion resistant linings on all ductile iron gravity sewer and force main pipe, fittings and valves are required. In general, the alignment of gravity sewer mains between dwelling units is not permitted.
3. Separation Requirements
a. The Palm Beach County Health Department's requirements for design, construction, clearance and separation of water, sewer and other facilities shall be strictly observed in addition to those as outlined in these Standards.
b. When storm drainage piping > 15 inch is to be installed parallel to gravity sewer lines a minimum of 15 feet of separation as measured from the outside edge of the pipes is required. Large storm drainage pipe (> 24 inch) to be located parallel to deep sanitary sewer lines (> 8 foot cut) requires separation greater than 15 feet as determined by Authority.
c. When drainage piping runs parallel to force mains, reclaimed mains, the minimum separation shall be eight feet. When running parallel to water main, the minimum separation shall be ten feet. Greater separation may be required from drainage pipe larger than 48 inches. When storm drainage piping crosses over or under sanitary sewer lines a minimum of 0.75 feet of separation as measured from the outside edge of the pipes is required. The sanitary sewer must be designed with a full length of polyethylene or Protecto 401 lined ductile iron pipe (DIP) centered on the crossing.
d. Sanitary sewer mains and sewer service runs (< 100 feet) or runs with multiple drainage crossings require polyethylene or Protecto 401 lined DIP from manhole to manhole.
e. No underground electric conductors, natural gas mains/feeders, or other utilities shall be placed closer than 4 feet horizontally and 6.0 inches vertically to water, sewer, or reclaimed lines and appurtenances as measured between the closest point between outside pipe walls.
4. Cover Requirements
Water, force and reclaimed mains shall have a minimum cover of 30 inches and a maximum cover of 48 inches unless otherwise specifically approved by Authority in writing. Sanitary sewer mains shall have a minimum of 3.3 feet of cover. Roadway crossings shall conform to requirements of the applicable permitting agency.
5. Setback Requirements
a. Mains (water, gravity sewer, force and reclaimed water) which are less than 9.5 feet deep, as measured from the pipe invert to finished grade, shall be installed a minimum of 15 feet horizontally from structures. This setback requirement also applies to new structures being constructed in the vicinity of existing Authority facilities. The 15 foot horizontal setback shall be as measured from the outside edge of the pipe to the nearest point of the structure, including underground (e.g. footers) or aboveground (e.g. roof overhangs) features. In addition, the 15-foot setback applies only to mains skirting a single structure. Where deep mains are installed between structures, setbacks greater than 15 feet will be required on each side. Mains deeper than 9.5 feet shall have a minimum horizontal setback calculated in accordance with the following equation:
S = 1' + (D/0.67)
S = Required horizontal set back from edge of main or structure to edge of pipe
D = Depth from bottom of structure to pipe invert
b. In general, sanitary sewer manholes shall be located in the center of roadway pavement. Manholes and sewer mains shall not be located closer than five feet to the curb line or the right-of-way line; whichever is closer, as measured from the outside edge of the manhole or pipe.
6. Replacement of Existing Facilities Required
a. Developer is required to replace any existing Authority facilities constructed of cement asbestos (CAP), cast iron (CIP), polyvinyl chloride (PVC) or vitrified clay (VCP) within the proposed development with currently approved materials at no cost to Authority. Design for relocation of existing water and sewer facilities must provide for continuity of service to existing customers as well as verification that the relocated facilities will not cause additional operation and maintenance expense to Authority. In no event will Authority schedule a preconstruction meeting for a relocation project until replacement easements are received in proper form for the relocated facilities. Removal and proper disposal of all CAP shall be in strict accordance with all applicable regulations and shall be the responsibility of the Developer/contractor performing same. A copy of the permit and a copy of the Solid Waste Authority (SWA) disposal ticket shall be supplied to Authority.
b. When a development causes offsite drainage and/or road improvements to be constructed, the Developer of same shall be required to replace any existing CAP, CIP, PVC or VCP lines located within road or drainage right-of-way/easements with approved materials as described above. All such installations, whether planned or unplanned, shall be subject to review by Authority prior to the actual commencement of any site/road work.
c. When a Developer's project causes existing Authority offsite facilities to be overloaded or subject to risk, Developer will be required to upgrade same to comply with current Authority specifications. The intent of this requirement is to cover situations similar to the following:
i. project flows cause an existing lift station, gravity sewer line or force main to be overloaded.
ii. project fire flows cannot be delivered by existing water distribution mains.
iii. roadway or drainage improvements cause existing facilities to be at risk.
7. Improvements Installed Over Water, Sewer, or Reclaimed Facilities
a. No paving or sidewalks shall be permitted within four feet of existing CAP or PVC water mains, force mains or reclaimed mains. No paving, sidewalk, landscaping, berms, or other improvements will be permitted over any portion of an existing utility easement (by plat or instrument), which has existing CAP, PVC or VCP water, sewer or reclaimed water lines.
b. Water mains, force mains and reclaimed water mains shall not be constructed under existing or proposed structures, sidewalks, concrete slabs, roadways, parking lots or other paved areas, unless specifically noted on the plans and approved by Authority. Areas to be covered with either concrete or paving, parking garages, walls, landscape berms, etc. shall be clearly noted on the plans. All utility easements must be clearly depicted on the landscaping plans. The EOR shall coordinate layout of water and sewer facilities with the landscaping plans for the project such that landscaping is minimized over water, sewer and reclaimed water lines and their respective easements. In general, easements shall preclude structures, trees, shrubs, berms, etc. so that unhindered access to all such facilities and mains is available at all times. Landscaping placed within a utility easement, with or without Authority's approval, is at property owner’s risk. Developer is required to execute Authority's standard Encroachment Agreement prior to a meter being set if improvements are designed to be located over Authority facilities. This includes, but is not limited to, landscaping, walls, berms, paver block, sidewalk and the like.
c. When developer causes grade changes at or near existing valve boxes, fire hydrants, manholes, backflow preventers, cleanouts, meter boxes or any other water, sewer or reclaimed facility the Developer shall adjust the affected facilities to finish grade in accordance with the Authority's standards.
8. Subaqueous Crossings
Design for subaqueous crossings requires the use of special materials. Class 56 DIP with ball and socket joints is required for pressure pipe (polyethylene or Protecto 401 lining is required for sewer force mains). Gravity sewer crossings of water bodies such as canals, lakes, water management tracts, etc. require the use of Class 56 polyethylene or Protecto 401 lined DIP for the entire tract (i.e. boundary line to boundary line). Manholes are not allowed in drainage easements, water management tracts or canal rights-of-way. Any gravity sewer pipe crossing of a water body will require the gravity sewer pipe to be installed within a steel casing. The casing shall be in accordance with Authority's Construction Detail Drawing No. 7 and installed, at a minimum, twenty feet beyond the top of each bank.
9. Service Connections
Each customer is required to have a dedicated service connection and meter. The Authority will not submeter water consumption to differentiate types of water use or for any other reason. The foregoing requirement does not preclude a Developer from submetering water usage on his property for his own purposes. Similarly, sewer customers are not permitted to connect to Authority facilities if their flow is piped through facilities not owned by the Authority. Each customer must have a dedicated service connection to the Authority's facilities. Residential uses shall be metered separately from non-residential uses in projects with mixed uses. Turbine meters are not permitted for any uses where low flows may occur. Permanent installations shall be metered in a manner acceptable to the Authority. The Authority requires that fire service lines be installed in conformance with requirements of the fire service agency of jurisdiction. Each such agency shall determine the appropriate fire flow requirements for each application and note the required fire flow in gallons per minute with their approval of the construction plans.
10. Prohibited Discharges to Sewer System
a. Projects handling or generating any toxic/hazardous substances shall be identified and their methods of pretreatment specified. Untreated discharges are not permitted into Authority facilities. Pretreatment procedures shall be acceptable to Authority and shall conform to all State and Federal regulations. Affected businesses include, but are not limited to, all commercial and industrial users of Authority facilities for which Federal and/or State pretreatment standards have been promulgated. This includes businesses such as plating and metal finishing operations. Businesses that qualify as significant users will be required to obtain a Wastewater Discharge Permit in accordance with Authority's Wastewater Pretreatment Program.
b. Storm water, roof drains, air conditioning and refrigeration condensate, cooling tower blowdown, softener brine, reverse osmosis reject water, treated groundwater or other "nondomestic sewage" are not permitted to discharge into Authority's sewer system.
B. CONSTRUCTION PLAN PREPARATION REQUIREMENTS
1. Prepare plans on 24" X 36" sheets using a scale no smaller than 1" =40', unless specific approval for a smaller scale is obtained from Authority. Zero lot line projects (when frontage is 45 feet or less on 50% or more of the lots) require plans prepared at a scale of no smaller than 1"=30'. Plans shall be drawn to scale using a scale that appears on a standard engineer's box scale. Like scales shall be used on plan & profile submittals with correct grids. (i.e. 1" 40' hor., 1"= 4'vert.) Scales and grid count must be consistent. Computer generated scales that cannot be read with a standard engineer's box scale will not be accepted for review.
2. Plans must indicate proposed finish floor/slab elevations and finished grade for roads, catch basins and other pertinent items. Place sanitary sewer data, including manhole invert and rim elevations, on plan sheets at each manhole; rim and invert elevations shown in tabular form only will be rejected. Profiles are required for gravity sewers and force mains (show all crossings). Profiles are also required for water mains with significant grade changes, including, but not limited to, aerial crossings, jack and bore and subaqueous crossings. When separate profile sheets are used all sewer lines must be depicted from manhole to manhole, pipe breaks between manholes will not be accepted. In addition, invert elevations must be clearly shown on profile sheets at each manhole. All profiles shall utilize the grid format. Plans utilizing the datum format shall be rejected.
3. An overall Master Plan sheet will be required for projects requiring more than two water and sewer plan sheets. The Master Plan sheet shall clearly show all water, sewer and reclaimed mains, values, fire hydrants, manholes, lift stations, metering facilities, connection points and existing facilities.
Other information pertinent to the project such as roadway, lakes, buildings, drainage system, etc. shall also be shown.
4. All piping crossings must be clearly identified on the plan sheets (this includes but not limited to, water mains, force mains, gravity mains, reclaimed mains, storm sewers, gas mains, underground electric, telecommunication lines and cable TV lines showing elevations of each). Clearance between the outside walls of the pipes/conduits, as well as pipe materials, must be clearly indicated on the drawings for each crossing.
Example:
Bottom 6" DIP WM = 14.73
Top 24" RCP = 13.18
All sewer service crossing water mains and drainage lines shall be clearly identified on plan sheet with elevations called out in tabular form on the construction plans and on the record drawings.
5. If the project will be built in phases the limits of each phase must be clearly indicated with the initial submittal; phasing must be decided prior to review. Each phase shall be separated by a valve and/or manhole.
6. Facilities which will ultimately be dedicated to the Authority which are installed on private property shall be in easements dedicated to Authority. Plans must show proposed easements by shading or otherwise easily distinguishable on plans.
7. All projects shall clearly indicate proposed driveway locations, streetlights and location of other utilities (electric, telephone, cable TV and gas). Particular emphasis must be given for proposed structures such as switch cabinets, transformers Bellsouth splice boxes and signal booster stations.
8. Provide a cover sheet showing the applicable project name and project number, sheet index, category of improvements, and vicinity sketch.
9. Provide all applicable detail drawings, including special profile sheets as required to show special or unique situations.
10. Authority's details must be used where applicable and shall include Board approved date. If details are found to have been altered without the knowledge of the Authority or without specifically stating in the transmittal which details are altered, the plans will be returned without review.
11. Obtain Fire Marshall approval of water system plans (approving fire hydrant placement and wet fireline requirements) prior to plan submission to the Authority. The Fire Marshall approved set shall indicate the minimum fire flow requirement for the project.
12. Submit Fire Marshall approved set, paving and drainage plan, preliminary plat or utility easement plan at scale matching potable water, reclaimed water, and/or wastewater plans, landscaping plan, master plan, survey, cover sheet and all plan sheets with relevant and easily readable location sketch, completed wastewater survey for projects with potential pretreatment requirements, lift station calculations, canal and road permits, including preliminary FDEP forms.
13. A utility plan is required for all subdivisions. The plan shall include a typical section of the utility easement showing all proposed utilities, all utility crossings, location and size of all utility above grade infrastructure boxes. This plan shall be provided prior to the Authority approving plans.
14. Prior to making plan submittal to Authority, verify all items on prerequisite checklist have been completed (see "Plan Submittal Prerequisite Checklist Water and Sewer").

D. LANDSCAPE GUIDELINES
1. Seacoast Utility Authority has developed these guidelines to help prevent damage to its facilities and help to limit damage to landscape plantings caused by the Authority when necessary maintenance and repair activities are performed. The Authority requires landscape plans be submitted as part of the construction plan review process for all projects. These plans shall include the Authority’s “typical tree with root barriers” details, if applicable. Water and sewer service shall not be activated if plantings are installed within the specified area of the Authority's facilities without the express written consent of the Authority. Property owners that wish to place landscaping in Authority easements will be required to submit proposed plans for approval and to execute Authority's Encroachment Agreement. Landscaping placed near the Authority's facilities is at the property owners' risk.
The Authority offers the following guidelines for placing landscaping near Authority facilities whether in an easement or the road right-of-way:
a. Ground cover type plants shall not be planted within five (5) feet of the Authority's valve boxes, metering or pumping facilities, gravity sewer manholes, water meters, sewer cleanouts, fire hydrants, and backflow prevention devices without approval from the Authority. Should ground cover be approved within five (5) feet of the Authority's facilities it shall not cover, block or in any way hinder access to the Authority's facilities.
b. Palm trees (other than Royal and exotic palms), shrubs, accent plants, and small trees, shall not be planted closer that ten (10) feet of water mains, force mains, gravity mains, reclaimed facilities, sewer service laterals, water service lines, water meters, sewer cleanouts, fire hydrants, or any other water and sewer appurtenances owned by the Authority without the approval of the Authority. The Authority will consider approving less that ten (10) feet separation, with the use of an approved root barrier, when it has been demonstrated that there are no other alternatives and the authority's facilities can be accessed and maintained and will not be at risk. The Authority will not consider any landscaping in the small tree, palm category which is less than seven (7) feet from its facilities with the root ball being a minimum of five (5) feet as measured from the outside of the root ball to the outside of the pipe. The Authority will consider approving accent plants and small shrubs with less than (7) feet of clearance from its facilities, with a minimum of (5) feet from facilities when there are no other alternatives.
c. Large trees, Royal Palms, and exotic palms are not to be planted closer that fifteen (15) feet to water mains, force mains, gravity mains, reclaimed facilities, sewer service laterals, water service lines, water meters, sewer cleanouts, fire hydrants and any other water or sewer appurtenances owned by the Authority without the approval of the Authority. The Authority will consider approving less than fifteen (15) feet separation, with the use of an approved root barrier, when it has been demonstrated that there are no other alternatives and the Authority's facilities can be accessed and maintained and will not be at risk. The Authority will not consider any landscape in this category which is less than ten (10) feet from its facilities with the root ball being a minimum of eight (8) feet as measured from the outside of the root ball to the outside of the pipe.
d. Only those plants which are classified as palm trees, shrubs, ground cover or accent plants are to be planted within five (5) feet of lift station or reclaimed water metering facilities and shall not interfere with the telemetry antenna.
e. Notorious invasive plants nuisance and problem trees are not to be planted within twenty five (25) feet of water mains, force mains, gravity mains, sewer service laterals, water service lines, water meters, sewer cleanouts, fire hydrants or any other water or sewer appurtenances owned by the Authority without the approval of the Authority.
f. Landscape berms, root barrier designation and root barrier details must be noted on all landscape and construction plans where used and shall be reviewed by the Authority for acceptance on a case by case basis.
g. Root barriers shall be Deep Root UB36-2, Root Solution RS-36, Biobarrier Root Control System or approved equal. All root barriers shall be installed to a minimum depth of thirty-six (36) inches and in strict accordance with manufacturer's written instructions and SUA Standards. Root barriers shall be installed a minimum of four (4) feet from the Authority' facilities.
h. All landscaping including accent plants shall be a minimum of 7.5 feet from fire hydrants.
2. Accent Plant is a plant which is not covered by any of the following definitions and is used sparingly within landscape areas.
3. Ground Cover is a plant in height no greater than two (2) feet at maturity.
4. Shrubs are plants in height no greater than three (3) feet at maturity.
