General Requirements

(1) Inflow and Infiltration. Each new Sanitary Sewer and replacement or extension that discharges directly or indirectly to the Authority Sewerage System, shall be designed and constructed so as to minimize, to the maximum extent possible, all Inflow and Infiltration into the Municipal or Authority Sewerage System. The owner and/or operator of any Sewerage System which discharges directly or indirectly to the Authority Sewerage System shall operate and maintain the System so as to eliminate any and all contaminated Inflow and Infiltration and any Inflow and Infiltration in quantities above that allowed by the Authority. (2) Storm Sewers, Sanitary Sewers, and Combined Sewers. The plumbing of any estate or premises discharging directly or indirectly to the Authority Sewerage System shall be arranged so as to keep any groundwater, storm water, surface water, roof and surface runoff, uncontaminated Cooling Water, Non-contact Cooling Water, and Non-contact industrial process waters separate from the Sanitary Sewage of the estate or premises. Groundwater, storm water, surface water, roof and surface runoff, uncontaminated Cooling Water, Non-contact Cooling Water, non-contact industrial process waters, and waters from any lake, swamp, pond, or swimming pool shall not be discharged to a Sanitary Sewer, except: (a) as authorized in 360 CMR 10.023(1) and (2); (b) swimming pool water may be discharged when there is no reasonable alternative and upon approval by the Authority, which will not be given when a receiving sewer has insufficient capacity to handle the discharge; and (c) Inflow to a Municipal Sewer or the Authority Sewerage System is prohibited except in those areas served only by a Combined Sewer. Where the Municipality provides only a Combined Sewer, separate Storm Sewer and Sanitary Sewer connections to the Municipality's Combined Sewer shall be constructed in accordance with any permit issued by the Authority. (3) Pretreatment Requirement. Every Person who directly or indirectly discharges Wastewater to the Authority Sewerage System shall provide the Pretreatment necessary to ensure that the discharge complies with 360 CMR 10.000.
