Centralized Wastewater System - Managed system of collection sewers and a in
contrast to a system that treats effluent on-site (conventional septic system,
innovative/alternative (I/A) system, or cesspool).
Certificate of Compliance - Certificate issued by the Board of Health to the owner
or operator of a system in accordance with 310 CMR 15.021 indicating that an
on-site system has been constructed or upgraded, and inspected in compliance
with Title 5.
Cesspool - Pit acting as a settling chamber for solids and leaching for liquids.
Cesspools that pose a threat to public health, safety or the environment must be
upgraded.
Cluster System - Wastewater collection and treatment system under some form
of common ownership, which collects wastewater from two or more dwellings or
buildings and conveys it to a treatment and disposal system that is located
nearby.
Commercial System - Serves a commercial establishment (e.g., retail/office,
restaurant or industrial) rather than a residence. Commercial systems serving
restaurants and other food preparation facilities must include a grease trap to
remove greases and oils before they enter the septic tank (310 CMR 15.230).
Composting Toilet - Technology that uses a biological process to degrade human
waste into a humus-like end product.
Conventional Pressure Distribution System - On-site wastewater treatment
system consisting of a septic tank and a subsurface soil absorption system that
relies on pressure distribution of the effluent.
Conventional Septic System - On-site wastewater treatment consisting of septic
tank and a trench or bed subsurface soil absorption system, which relies on
gravity to distribute effluent.
Conveyance Lines - Pipes that connect the various parts of a septic/on-site
system (e.g., building sewer, septic tank, distribution box).
Cover Material - Soils placed on top of a soil absorption system to bring the area
to finish grade.
Creeping Failure - Condition in which the biomass of a soil absorption system
becomes so intensely developed that no water can flow through it, eventually
causing system malfunction.
