If a portion of the water furnished to any premises is not directly or indirectly discharged into the sewerage system, the quantity of such water shall be deducted in computing the sewerage service charge or rental, provided a separate meter shall be installed and operated to register the quantity so not discharged into the sewerage system. Provided also, that where it is not practicable to meter the portion of the water not discharged into sewerage system, such adjustment may be made as shall be fair and equitable in order to determine the amount of such service charge or rental; but until such adjustment shall remain in full force and effect.

(l)

Unmetered water supply.

(1)

If any premises discharge normal sewage or industrial waste into the sanitary sewerage system, either directly or indirectly, obtain part of all of the water used thereon from sources other than the city, and the water so obtained is not measured by a meter of equivalent specifications to the meters used by the city, then in such case the city shall permit the discharge of normal sewage or industrial waste into its sanitary sewerage system only when the owner of such premises or some other interested party shall at his own expense supply a water meter of equivalent specifications to those installed by the city in connection with the city water system. Each water meter shall be installed to measure all water received on such premises and the above charges and rates shall be applied to the quantity of water received as measured by such meter. If, because of the nature of the source of the water supply, the city deems it impracticable to thus meter the water on any premises, the council may, by resolution, establish a flat charge per month in accordance with the estimated use of water on such premises.

(m)

Construction requirements.

(1)

Every private sewer connection, for new construction, in a basement shall have a sewer check valve installed.
