<br />breakers and provision is made to protect from freezing (see Minnesota Rules, Chapter 4714, Sections 603.5.7, 312.6, and 301.1.2).
<br />20. All newly installed or replacement pipes, pipe fittings, plumbing fittings and fixtures, including backflow preventers, that are installed on
<br />potable water systems or systems that are designed to distribute water for potable use, are required to meet the Reduction of Lead in
<br />Drinking Water Act, which establishes a maximum lead content of 0.25 percent by weighted average of the wetted surfaces. Solder and flux
<br />for potable water systems shall contain less than 0.2 percent lead. Joints must include non -corrosive non -toxic paste -type flux complying
<br />with ASTM B813 (see Minnesota Rules, Chapter 4714, Section 605.3.4). See Minnesota Rules, part 4714.0604 and UPC part 604.11.
<br />21. Do not exceed the manufacturer's specifications for curvature of pipe and deflection at pipe joints. Securely close all open ends of pipe
<br />and fittings with watertight plugs when work is not in progress. Keep the interior of all pipes clean and remove any dirt or debris from
<br />joint surfaces after the pipes have been lowered into the trench. Install all valves plumb and located according to the plans.
<br />22. Insulate the watermain at locations indicated on the plans. Provide a minimum insulation thickness of 4 inches. The insulation must be at
<br />least 4 feet wide and centered on the pipe. Install the insulation boards 6 inches above the tops of the pipes on mechanically compacted
<br />and leveled pipe bedding material. Use high density, closed cell, rigid board material equivalent to DOW Styrofoam Highload 40 Polystyrene
<br />Insulation. Individual insulation board dimensions typically measure 4' wide by 8' long by 2" thk.
<br />SANITARY SEWER:
<br />1. Unless otherwise indicated, use reinforced, precast, concrete maintenance holes conforming to ASTM C478, furnished with
<br />precast bases. Sanitary sewer maintenance holes shall be supplied with pre -formed inverts and flexible neoprene sleeve
<br />connections for all lateral lines 375 mm (15 inches) in diameter or less, unless otherwise indicated. Joints for all precast
<br />maintenance hole sections shall have confined, rubber "0"-ring gaskets in accordance with ASTM C443. These joints are
<br />normally used in sewers to hold infiltration and exfiltration to a practical minimum and are adequate for hydrostatic heads up
<br />to 30'. The inside barrel diameter shall not be less than 48 inches.
<br />2. All joints and connections in the sewer system shall be gastight or watertight. Use flexible compression joints to make
<br />watertight connections to manholes in accordance with Minnesota Rules part 4714.0719.6. Where permitted by the
<br />administrative authority, approved resilient rubber joints or waterstop gaskets must be used in order to make watertight
<br />connections to manholes and other structures. Use Fernco "Concrete Manhole Adaptors" or "Large Diameter Waterstops",
<br />Press -Seal "Waterstop Grouting Rings", or approved equal. Cement mortar joints are permitted only for repairs or
<br />connections to existing lines having such joints.
<br />3. The building sewer starts 2 feet outside of the building. See Uniform Plumbing Code (UPC) part 715.1. Material installed
<br />within 2 feet of the building must be of materials approved for use inside of or within the building.
<br />4. The exterior sanitary sewer piping must comply with the following requirements: (A) Double wyes may not be used for
<br />drainage fittings in the horizontal position (see Minnesota Rules, Chapter 4714, Section 310.5). Proper pipe slope cannot be
<br />maintained on both of the offset branches. (B) Changes in direction in drainage piping must be made by appropriate use of
<br />wyes and bends (see Minnesota Rules, Chapter 4714, Section 706.0). Tees are not allowed where the direction of flow
<br />changes from either vertical to horizontal or horizontal to horizontal.
<br />5. Pipe: Use solid -core, Schedule 40 Polyvinyl Chloride (PVC) Plastic Pipe for all designated PVC sanitary sewer services outside
<br />of the building. The PVC pipe shall meet or exceed the industry standards and requirements as set forth by the American
<br />Society for Testing and Materials (ASTM) D1785 and D2665. Fittings must comply with ASTM D1866, D2665, or F794. Joints
<br />must be approved mechanical or push -on utilizing an elastomeric seal. Use of solvent cement joints is allowed for building
<br />services. Solvent cement joints in PVC pipe must include use of ASTM F656 purple primer and cement in accordance with
<br />Uniform Plumbing Code (UPC), part 605.13.2. Pipe with solvent cement joints shall be joined with PVC cement conforming to
<br />ASTM D2564. The installation must comply with ASTM D2321, which requires open -trench installation on a continuous
<br />granular bed.
<br />6. Cleanouts: Install cleanouts on all sanitary sewer services in accordance with UPC part 719.0 and 1101.12. The distance
<br />between cleanouts in horizontal piping shall not exceed 100 feet for pipes 4-inch and over in size. Cleanouts shall be of the
<br />same nominal size as the pipes they serve. Include frost sleeves and concrete frame and pipe support Install a meter box
<br />frame and solid lid (Neenah R-1914-A, or approved equal) over all cleanouts.
<br />7. Testing: Pressure test all sanitary sewer lines in accordance with the Minnesota Rules parts 4714.0712 and 4714.0723 and
<br />UPC parts 712.0 and 723.0. Test all flexible sanitary sewer lines for deflection after the sewer line has been installed and
<br />backfill has been in place for at least 30 days. No pipe shall exceed a deflection of 5%. If the test fails, make necessary
<br />repairs and retest.
<br />8. Install flexible watertight frame/chimney seals on all sanitary sewer maintenance holes in order to seal the outside of the
<br />chimney from the cast iron frame down to the cone. The seal shall be a continuous seamless band made of high quality
<br />EPDM (Ethylene Propylene Diene Monomer) rubber with a minimum thickness of 65 mils. Use Internal/External Adapter Seal
<br />as manufactured by Adaptor, Inc. (www.adaptorinc.com/wp-content/uploads/2019/04/ADAP_IEManholeSeal.pdf), Infi-Shield
<br />Uni-band one piece molded sealing system as manufactured bySealing Systems, Inc. (www.ssisealingsystems.com), ar approved
<br />equal.
<br />9. Use Neenah Foundry Co. R-1642 casting with self-sealing, solid, type B lid, or approved equal, on all sanitary sewer
<br />maintenance holes. Covers shall bear the "Sanitary Sewer" label.
<br />10. Trace Wire: Install locating wires on all conductive and non-conductive storm sewer, sanitary sewer, and water lines in
<br />accordance with the Minnesota Rural Water Association (MRWA) Trace Wire Specification Guide and Details
<br />(www.mrwa.com/PDF/TracerWireSpecGuideFinalweb9.pdf). Use #12 HDPE-insulated copper -clad steel wire rated for underground
<br />service. The color of the insulating jacket shall be as follows: ground=red, storm sewer=green, sanitary sewer=green, and
<br />water lines=blue. Install the wire on the bottom side of the pipe below the spring line. Fasten the wire to the pipe with
<br />tape or plastic ties at 5' intervals. Do not wrap the trace wire around the corresponding utility. Do not connect the trace
<br />wire to existing conductive utilities. Use Copperhead Dryconn 3-Way or Locking Snake Bite connectors rated for underground
<br />direct bury applications or approved equal at all crossings or service connections. Twist on connectors are not allowed.
<br />Trace wire must be properly grounded at all dead ends and services. Install grade-level/in-ground trace wire access boxes
<br />and drive-in magnesium grounding anodes at all dead ends, services, and fire hydrants. Trace wire access boxes shall be
<br />color coded as follows. storm sewer=green, sanitary sewer=green, and water lines=blue.
<br />11. Detectable Warning Tape: Install detectable underground warning tape directly above all underground utilities at a depth of
<br />457 mm (18 inches) below finished grade, unless otherwise indicated. Underground warning tape shall be 3-inches wide with
<br />a minimum 5.0 mil overall thickness. Tape shall be manufactured using a 0.8 mil clear virgin polypropylene film, reverse
<br />printed and laminated to a 0.35 mil solid aluminum foil core, and then laminated to a 3.75 mil clear virgin polyethylene film.
<br />The aluminum backingmakes underground assets easyto find usinga non-ferrous locator. Tape shall beprinted usinga
<br />9 P
<br />diagonally striped design for maximum visibility and meet the APWA Color -Code standard for identification of buried utilities.
<br />Use Pro -Line Safety Products (www.prolinesafety.com) detectable marking tape or approved equal.
<br />12. The minimum depth of cover for sanitary sewer without insulation is 5 feet. Insulate sanitary sewer services at locations
<br />where the depth of cover is less than 5 feet. Provide a minimum insulation thickness of 4 inches. The insulation must be
<br />at least 4 feet wide and centered on the pipe. Install the insulation boards 6 inches above the tops of the pipes on
<br />mechanically compacted and leveled pipe bedding material. Use high density, closed cell, rigid board material equivalent to
<br />DOW Styrofoam Highload 40 Polystyrene Insulation. Individual insulation board dimensions typically measure 4' wide by 8' long
<br />by 2" thk.
<br />13. Install all pipe with the ASTM identification numbers on the top for inspection. Commence pipe laying at the lowest point in
<br />the proposed sewer line. Lay the pipe with the bell end or receiving groove end of the pipe pointing upgrade. When
<br />connecting to an existing pipe, uncover the existing pipe in order to allow any adjustments in the proposed line and grade
<br />before laying any pipe. Do not lay pipes in water or when the trench conditions are unsuitable for such work.
<br />14. All saddle tee or wye fittings must provide an integrally molded pipe stop in the branch for positive protection against service
<br />pipe insertion beyond the inside of the sewer main pipe wall.
<br />15. Terminate all new sewer stubs with a water -tight gasketed cap properly braced in order to withstand the
<br />infiltration-exfiltration test. Install grade-level/in-ground trace wire access boxes and drive-in magnesium grounding anodes
<br />at the end of all stubs.
<br />16. Televise all existing lines prior to connection.
