(a) The acceptability of any discharge into the sanitary and storm sewerage systems shall be subject to the conditions of this section and the Sewer Use Code of the Northeast Ohio Regional Sewer District. The District will be responsible for determining the acceptability of any discharge, primarily industrial, to the sanitary sewerage system and the necessity for any pretreatment.
(b) Sanitary sewers shall be used to discharge all water-borne wastes from water closets, urinals, sinks, lavatories, bathtubs, showers, laundry tubs, drinking fountains, soda fountains, refrigerator drips and floor drains, whether from residences, factories, business buildings, schools or public buildings, wherever or however located, or for other purposes enumerated in the Ohio Revised Code and for no other purpose. No person shall discharge any sanitary waste into any storm sewerage system.
(c) No person shall discharge, directly or indirectly, any of the following into the sanitary sewerage system:
(1) Materials or substances which are in any way harmful or destructive to any part of the waste water disposal system;
(2) Concentrations of any toxic or deleterious materials or substances in excess of any limits set thereon;
(3) Any noxious, toxic or malodorous liquids, solids or gases which, by reason of their nature or quantity, are or may be sufficient, either alone or by interaction:
A. To cause fire or explosion;
B. To be injurious in any other way to the operation of the waste water disposal system; or
C. To prevent entry into the sewers for their maintenance or repair;
(4) Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the system; and
(5) Any wastewater which causes a hazard to human life or creates a public nuisance.
(d) No discharger shall increase the use of potable or process water, or mix separate waste streams for the purpose of diluting a discharge as a substitute for pretreatment in order to achieve compliance with the standards set forth in this section.
(e) No person shall discharge or cause to be discharged into the sanitary sewerage system any flood water, storm water, surface water, ground water, roof run-off, cistern overflow, footer drain, loading dock drain, swimming pool water (except backwash), uncontaminated cooling water or unpolluted industrial process water. All such storm water and unpolluted drainage shall be discharged to a storm sewer or to a natural drainage outlet as approved by the Village Engineer.
(f) Pretreatment and interceptors shall be provided for discharges as outlined in this section, the Ohio Plumbing Code and the Sewer Use Code of the Northeast Ohio Regional Sewer District. Sewer connections from wash racks, grease racks, loading docks and all types of commercial or industrial installations where grease,oil or other petroleum waste products are discarded shall be connected to appropriate grease separators and/or sand or oil traps before connection to the sanitary sewer. Sewer connections from commercial kitchens shall be connected to appropriate grease traps.
(g) In flood-prone areas, as determined by the Village Engineer, the following requirements shall be followed so as to safeguard against the discharge of flood waters into the sanitary sewerage system:
(1) A positive shut-off valve, such as a ball valve, as approved by the Village Engineer, shall be installed in the sanitary connection that leads to any plumbing fixture or drain that is subject to being flooded. The valve shall be located outside the building, either in a vault or under a valve box, so as to be readily accessible.
(2) When a flood occurs, authorized personnel, under the direction of the Village Engineer, shall close the valve so as to prevent flood waters from entering the sanitary sewerage system.
(3) After the flood waters have receded, any water remaining in a basement or other flooded area shall be removed by pumping before the shut-off valve is reopened by authorized personnel under the direction of the Village Engineer.
(4) The positive shut-off valve is intended solely to prevent flood waters from entering the sanitary sewerage system and shall be closed and reopened only by authorized personnel under the direction of the Village Engineer. No property owner or any other person shall operate or tamper with the shut-off valve.
(h) In addition to the shut-off valve, a backwater valve or other approved backflow preventor shall be installed in the sanitary connection. The property owner may install a backwater valve in the storm connection to buildings where the footer drains are subject to storm water backflow. The backwater valves shall be controlled and maintained by the property owner and shall be located so as to be accessible for inspection, cleaning and maintenance.
