Sanitary Drainage
These are the standards in SynC Standards that cover Sanitary Drainage. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Grease Interceptors
Grease interceptors that pretreat the fats, oils, and grease carried by the drainage from commercial kitchens, cafeterias, commissaries, bakeries, and other food-service operations before that drainage reaches the sanitary building drain: hydromechanical grease interceptors rated under PDI G101 and ASME A112.14.3, automatic grease removal devices under ASME A112.14.4, and gravity grease interceptors of precast concrete, cast-in-place concrete, fiberglass, or polyethylene. Covers the interceptor types furnished, the sizing method and the inputs it needs, the flow control fitting and air intake, body and tank materials, structural loading and anti-flotation of buried tanks, inlet and outlet fittings, access risers and covers, venting, the effluent sampling point, which fixtures and appliances connect to the interceptor, the grease waste pipe material and slope between those fixtures and the interceptor, setting and testing, and the pump-out program the Owner carries after acceptance.
- Sanitary Waste and Vent Piping
The sanitary drain, waste, and vent piping inside a building and the building drain out to five feet beyond the foundation wall, in commercial, institutional, industrial, and multifamily buildings: the pipe, fittings, joints, and couplings in cast iron, PVC, ABS, copper, galvanized steel, stainless steel, and polyethylene; the fixture traps, trap arms, and the venting that protects them; the slope and the changes of direction of horizontal drainage; the indirect waste receptors that take equipment discharge; the connections to fixtures, floor drains, cleanouts, grease interceptors, sumps, and ejectors; hangers, vertical support, seismic restraint, thermal movement, acoustic treatment, sleeves, and firestopping; below-slab bedding and backfill; and the rough-in and final tests that prove the system tight.
- Site Utilities
Exterior underground wet and dry site utilities for commercial, institutional, and industrial building projects, beginning 5 feet outside the building footprint and extending to the point of connection at the public main, meter, or utility owner's facility. Covers the site domestic and fire water service and on-site water distribution (ductile iron and PVC pressure pipe, valves, hydrants, service fittings, thrust restraint), the site sanitary sewer (gravity collection mains and laterals, and pressurized force mains and low-pressure sewer), and the underground dry-utility infrastructure for electrical and telecommunications service (direct-buried and concrete-encased duct banks, conduit, and manholes/handholes). Also covers the common trenching, bedding, embedment, backfill, separation, tracer-wire and marking-tape locating, pressure and leakage testing, deflection and air testing, and water-main disinfection that apply across these systems.
