(A) Infiltration shall mean water entering the sewerage system from the ground through such sources as, but not limited to, defective pipe joints, connections or manhole walls. Infiltration does not include, and is distinguished from inflow.
(B) Inflow shall mean the water discharged into the sewerage system from such sources as, but not limited to, roof leaders, cellar, yard and area drains, foundation drains, cooling water discharges, sewers, catch basins, storm waters, surface run-off or street wash waters or drainage. Inflow does not include, and is distinguished from, infiltration.
(C) Infiltration/inflow shall mean the total quantity of water from both infiltration and inflow without distinguishing the source.
(D) Excessive infiltration/inflow shall mean the quantities of infiltration/inflow which can be economically eliminated from a sewerage system by rehabilitation, as determined by a cost-effective analysis that compares the costs for correcting the infiltration/inflow conditions with the total costs for transportation and treatment of the infiltration/inflow, subject to EPA provisions.
(E) The owner of any property serviced by a building sewer shall maintain said sewer in such a manner as to prevent excessive amounts or infiltration/inflow from entering the public sewerage system. The owner of any building whose sewer is not properly maintained shall be notified, and he shall have the necessary repairs made at his own expense. Before any underground portions are covered, the owner shall notify the town when the building sewer is ready for inspection.
