Business & Industrial Users

Pretreatment program purpose  

  • Prevent the introduction of pollutants into the wastewater treatment system that will interfere with the operation of the treatment plant, pass through the treatment plant inadequately treated, or otherwise be incompatible with the system.
  • Protect treatment plant personnel who may be affected by wastewater or sludge in the course of their employment.
  • Promote the reuse and recycling of industrial wastewater and sludge from the treatment facility.
  • Protect the general public and the environment.
To help meet these goals, Chapter 19, Wastewater Pretreatment lists general and specific discharge prohibitions that are applicable to all users of the system, whether they are industries, commercial facilities, or residents. The Ordinance also describes conditions under which an industrial facility will be considered a Significant Industrial User and issued a Wastewater Discharge Permit to further control the discharge of certain pollutants.

These conditions include:

  • Industries that are subject to Categorical pretreatment standards according to Federal Regulation.
  • Industries that discharge an average of 25,000 gallons per day or more of process wastewater.
  • Industries that contribute a process waste stream which makes up 5% or more of the average dry weather capacity of the treatment plant.
  • Other industries that have a reasonable potential to adversely affect the treatment system.

New businesses

All new businesses must submit a Wastewater Survey Application for Discharge Permit After reviewing the information the Township will determine if your business fits certain criteria and may be issued a Discharge Permit.

For example, if you are a manufacturer or perform any type of industrial activity, you may be considered a Significant Industrial User and issued a permit to control the discharge of certain pollutants to the sanitary sewer. Even if it is determined that your facility is not a Significant Industrial User, the Township may want to schedule a visit to discuss the use and storage of chemicals, cleaning activities, and other pretreatment matters.

Restaurants, bakeries, and other food service facilities,

or a business which performs vehicle maintenance on site


Your facility will be inspected to determine if a Fats, Oil & Grease (FOG) Discharge Permit is applicable. If the primary business does not deal directly with food preparation or vehicle maintenance, but your facility has a cafeteria or fleet maintenance garage, you may fit this category. More information on the Township's FOG program.

Harmful Substances

If substances other than those found in domestic wastewater find their way into the collection system or to the treatment facility, bad things can happen. Such substances include but are not limited to:

  • Chemicals, such as anti-freeze, gasoline or other organic solvents, which may cause dangerous gas to form in the sewer lines, affecting the public or Township work crews.
  • High concentrations of heavy metals, such as cadmium, chromium or zinc, that may be toxic to the bugs at the plant, interfering with their ability to decompose the waste properly.
  • Petroleum, or vegetable based oils and greases, that can cause blockages in the sewer lines or adversely affect the treatment process.
To minimize the possibility of harmful substances entering the wastewater treatment system, please review the Prohibited Discharge Requirements which sets rules and regulations on what can and cannot be discharged into the system.
