For each property located within the Township served by the sewer system and having available to it the use thereof, there is hereby imposed a base charge of $224 per year, payable in quarterly installments of $56 each, as hereinafter provided.

Multiple Use. In case of a combination of one or more commercial, industrial or institutional establishments, private dwellings (including mobile home space, row houses, semidetached houses and townhouses and individual dwelling units within a multiple-dwelling building), firehouses, churches, schools or municipal buildings in one property all having the use of the sewer system through one sewer connection, then each such establishment shall be charged the above-mentioned base charge as through each were separately connected to the sewer system; and if there is only one water meter for any such combination, the Township may estimate the amount of water used by each individual establishment if necessary for the purpose of establishing additional sewer rental charges imposed by § 18-404 hereof.

Meter Rates. For all properties located within the Township served by the sewer system and having available to it the use thereof, other than (A) private dwellings (including each mobile home space, or house, semidetached house and townhouse and individual dwelling unit within a multiple dwelling building), (B) firehouses, (C) churches, and (D) municipal buildings, there is hereby imposed an additional sewer rental, payable quarterly, for all discharge to the sewer system in excess of 14,000 gallons for any three-month period, based on the quantity of water used (or on discharge to the sewer system as hereinafter provided), at the rate of $4 per 1,000 gallons of water used (or discharged to the sewer system as hereinafter provided).

Schools. Schools shall be charged additional sewer rental, based upon the quantity of water used by them (or on discharge to the sewer system), at the rates and in the manner provided in Subsection 1 hereof; provided, however, that notwithstanding said Subsection 1, the additional sewer rental charge for each school for each quarterly billing period ending September 30 shall not be less than an amount equal to the average of the additional sewer rental charges for the three billing periods next preceding the period ending September 30 in each year.

Other Seasonal or Intermittent Use. Additional sewer rentals (for any quarterly billing period) imposed upon seasonal or other intermittent users of the sewer system, other than schools, at the sole discretion of the Township, may be based upon actual flow or upon average peak period flow; provided, however, that the Township shall not impose additional sewer rentals on the basis of average peak period flow until it shall have received at least one full year's flow record with respect to the subject user.

The Township reserves the right to require any property not subject to payment of additional sewer rentals hereunder to pay such rentals if, because of suspected infiltration or for any other reason, the Board of Supervisors of the Township believes that such property is discharging to the sewer system flow in excess of 14,000 gallons per use per quarter. Such additional sewer rentals shall be imposed by resolution of the Board of Supervisors of the Township upon not less than 10 days' prior written notice to the subject property owner. In such event, the Authority or Township, at its own expense, may require the installation of water or sewage measuring devices as provided in § 18-406 hereof.

Nothing herein contained shall be deemed to require the Board of Supervisors of the Township to impose additional sewer rentals upon any property other than in accordance with Subsections 1 and 2 of this Section.

In addition to sewer rents and charges imposed hereby, there is hereby imposed upon each committed basic billing unit (hereinafter defined) a reserve capacity charge of $168 per year, payable in equal quarterly installments in accordance with the provisions of § 18-408 hereof.

By appropriate action of the Board of Supervisors, the Township shall establish rules and regulations regarding commitments of reserve capacity in the sewer system to anticipated future users. Under such rules and regulations, the owner of any property in the Township not connected to the sewer system and the owner of any property already connected to the sewer system but desiring to reserve the right to make additional connections to the sewer system may make application for reservation of capacity in the sewer system for such future anticipated use. From and after granting of such reservation of capacity by the Township, the reserve capacity charge hereinabove imposed shall be payable.

For the purpose of this Part, one reserve capacity charge shall be payable with respect to each reservation of the following uses:

Each use described in Subsection 3A through E above shall be deemed a basic billing unit for the purposes of this Part.

Nothing herein contained shall be deemed to require that the Township grant any reserve capacity commitments.

Methods of Measuring Volume.

Measuring Devices. All meters or measuring devices required to be used under the provisions of this Part (except those provided by the water company or those provided by the Township or Authority under Subsection 1B above) shall be furnished and installed by the Township at the expense of the property owner. All such meters or measuring devices (except those provided by the water company) shall be under the control of the Township and may be tested, inspected or repaired by Township employees or agents whenever the Sewer Manager shall deem necessary. The owner of the property upon which such measuring device is installed shall be responsible for its maintenance and safekeeping; and all repairs thereto shall be made by the Township at the property owner's expense, whether such repairs are made necessary by ordinary wear and tear or other causes. Bills for such installation and repairs shall be due and payable at the same time and collected in the same manner as are the bills for sewer services. Such bills, from and after their due date, shall constitute a lien upon the property upon which such measuring device is installed.

Meter Readings. The Township shall be responsible for the reading of all meters or measuring devices (except to the extent the water company's readings are used), and they shall be made available to Township employees or agents for meter readings at any reasonable time.

Quarterly charges for sewer service shall be subject to a penalty of 5% if not paid within 30 days after they are due. If not paid within 60 days after becoming due, the bill plus the penalty shall bear interest from the due date at the rate of 1% per month or fraction thereof until paid, and the Township shall have the right to cut off sewer service from such premises and not to restore the same until all bills against the same and the cost of cutting off and restoring service shall have been paid.

All persons connected to the sewer system must give the Township their correct address. Failure to receive bills will not be considered an excuse for nonpayment nor permit an extension of the period during which bills are payable at face.

All sewer rentals, together with all penalties thereon, not paid on or before the end of one year from the date of each bill shall be deemed to be delinquent. All delinquent sewer rentals and all penalties thereon shall be a lien against such property in the office of the Prothonotary of Bucks County and shall be collected in the manner provided by law for the filing and collection of such liens.

The funds received by the Township from the collection of the sewer rentals and charges and all penalties thereon, as herein provided for, and any fines collected by the Township in connection with the sewer system shall be segregated, earmarked and deposited in a separate fund, to be designated as the "Sewer Revenue Account."

The funds received by the Township from payment of connection charges, inspection charges and tapping fees and all penalties thereon, imposed by the Authority and collected by the Township as its agent, shall be deposited in the above-mentioned Sewer Revenue Account.

Said funds shall be used only for the purpose specified in any lease or agreement it may enter into for and of, or in connection with, said sewer system, with the Authority, in accordance with the provisions of the Act of May 2, 1945, P.L. 382, as amended and supplemented.

Approval of Industrial Wastes.

Permit.

No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff or subsurface drainage into the sewer system.

No person shall discharge or cause to be discharged any of the following into the sewer system:

Any cooling water, unpolluted industrial or commercial process water.

Any vapor or steam.

Any liquid having a temperature higher than 140° F.

Any fluid waste containing in excess of 100 parts per million of fat, oil, wax, or grease, either vegetable or mineral, or containing substances which may solidify between 32° F. and 100° F.

Any liquids, solids or gases, such as benzene, gasoline, naphtha, fuel oil or other volatile, explosive or flammable substance, which, by reason of its nature or quality, may cause fire or explosion or be in any way injurious to persons, to the sewer system or the operation thereof.

Any unshredded garbage. The installation and operation of any garbage grinder equipped with a motor of greater than 1/2 horsepower shall be subject to review and approval by the Township, the County Authority and the Joint Authority.

Any waste containing a five-day BOD in excess of 250 ppm.

Any waste containing a total solids content in excess of 800 ppm.

Any waste having a chlorine demand in excess of 10 ppm.

Any fluid having a pH lower than 5.5 or higher than 9.5.

Any wastewater containing any substances which are not amenable to treatment or reduction by the biochemical wastewater treatment processes employed or are amenable to the treatment only to such a degree that the effluent of the sewage treatment works cannot meet the requirements of agencies having jurisdiction over the discharge to the receiving stream.

Any toxic substance not mentioned in the foregoing list that will pass through the treatment works and exceed the maximum permitted levels for such substance under the requirements of State or other governmental agencies.

Any substance prohibited by any permit issued by Commonwealth of Pennsylvania.

Any waste containing toxic or poisonous substance in excess of the following limits, measured at the point of discharge into the sanitary sewers:

A garbage disposal unit with a motor of 1/2 horsepower or less may be installed in any single-family dwelling or unit without a permit.

Air-conditioning units using 20 gallons of water per minute or less and having a discharge temperature of not over 140° F. may discharge into the sewer system.

Floor drains used for washing and cleaning will be permitted only on application to the Township, the County Authority and the Joint Authority and only after provisions have been made for the removal of sand, grit, oil, grease, garbage or any other materials.

The surcharge is based on a waste having a five-day 20° C. BOD greater than 250 ppm.

A total solids content greater than 800 ppm.

In the case of waste containing heavy metals, either in suspension or solution, or when, in the opinion of the Township, the suspended solids do not represent the true characteristics of the solids loading, the Township reserves the right to use total solids instead of suspended solids.

In the case of waste containing substances or materials that only can be treated with extra care and costs and where the surcharge as stated above does not apply, they may accept after a study of the waste has been made and a formula for the discharge has been established.

In order to ascertain the strength of every industrial waste, the Township or the County Authority or the Joint Authority shall cause appropriate analysis to be made at least four times each year of every industrial waste entering the sewer system, the coverage of which shall be used to establish the surcharge for the ensuing year. The Township reserves the right to, and may from time to time, adopt, revise amend and readopt such rules and regulations as it deems necessary and proper for the use and operation of the sewer system.
