1 CHAPTER 7 SANITARY DRAINAGESECTION provisions of this CHAPTER shall govern thematerials, design, construction and installation of sanitarydrainage Sewer building in which plumbing fix-tures are installed and all premises having DRAINAGE piping shallbe connected to a public sewer, where available, or an approvedprivate sewage disposal system in accordance with theInterna-tional Private Sewage Disposal Separate sewer building havingplumbing fixtures installed and intended for human habitation,occupancy or use on premises abutting on a street, alley oreasement in which there is a public sewer shall have a separateconnection with the sewer. Where located on the same lot, mul-tiple buildings shall not be prohibited from connecting to acommon building sewer that connects to the public Sewage or other waste from aplumbing system that is deleterious to surface or subsurfacewaters shall not be discharged into the ground or into anywaterway unless it has first been rendered innocuous throughsubjection to an approved form of Damage to DRAINAGE system or public to the public sewer system or to the functioning ofthe sewage-treatment plant shall be treated and disposed of inaccordance with Section 1003 as directed by the code SANITARY DRAINAGE system shall be tested inaccordance with Section connection of a steam exhaust.

2 Blowoff or drip pipe shall not be made with the building drain-age system. Wastewater when discharged into the buildingdrainage system shall be at a temperature not higher than 140 F(60 C). When higher temperatures exist, approved coolingmethods shall be Engineered SANITARY DRAINAGE sys-tems shall conform to the provisions of Sections and DRAINAGE piping in food service areas.(Sectiondeleted)SECTION Above-ground SANITARY DRAINAGE and vent soil, waste and vent pipe shall conform to one ofthe standards listed in Table Underground building SANITARY DRAINAGE and building SANITARY DRAINAGE and vent pipeshall conform to one of the standards listed in Table Building sewer sewer pipe shall conformto one of the standards listed in Table fittings shall be approved for installationwith the piping material installed and shall conform to therespective pipe standards or one of the standards listed in Chemical waste chemical waste system shallbe completely separated from the SANITARY DRAINAGE chemical waste shall be treated in accordance with before discharging to the SANITARY DRAINAGE system.
