SynC · Topic
These are the standards in the SynC Standards library 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 — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 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.
Grease interceptors and grease-removal devices that pretreat fats, oils, and grease (FOG) bearing wastewater from food-service establishments before it discharges to the sanitary building drain or public sewer. Covers hydromechanical grease interceptors (HGI) — point-of-use under-fixture units and larger flow-rated units rated per PDI G101 and ASME A112.14.3 — automatic grease removal devices (GRD) per ASME A112.14.4, and gravity grease interceptors (GGI) — large in-ground or exterior precast concrete vaults sized by liquid volume and retention time. Addresses interceptor type selection, flow-rate and volume sizing methods, flow control fittings and air intake, trapping and venting, materials, accessible covers and maintenance access, sample and monitoring ports, the connection of grease-laden fixtures, and the operations and pump-out maintenance program. Applicable to commercial kitchens, restaurants, cafeterias, institutional food service, commissaries, bakeries, and similar food-service establishments.
Sanitary drain, waste, and vent (DWV) piping systems inside buildings from the point of connection at plumbing fixtures to the point of connection with the building sewer, including all above-grade and below-slab horizontal branches, vertical stacks, and vent piping. Covers pipe materials (hubless and hub-and-spigot cast iron, PVC DWV), drainage-pattern fittings, joints, cleanouts, floor drains, traps, hangers and supports, buried and below-slab piping, slope, and field testing. Applicable to commercial, institutional, and industrial buildings.
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.
