Pretreatment

Residential Users

Granger-Hunter Improvement District has an active and ongoing Pretreatment Program. A key element of our Pretreatment Program includes our staff working with our customers to remove Fats, Oils and Grease (F.O.G.) and other harmful materials from the public wastewater system. Please call our Pretreatment personnel at 801.955.2204 with any questions.

When water and other materials go down the drain, it’s often thought that these things are gone forever right? This is not the case. In fact, the water from your home travels miles through sewer lines before it reaches the treatment plant, Central Valley Water Reclamation Facility (CVWRF). Flushing the wrong materials can cause issues in the sewer system resulting in sewer backups within the community and even your home. To avoid this expensive problem, we need your help.

What About the Kitchen?

Fats, oils, and grease (FOG) cause most sewer plugs and backups. FOG is produced from daily cooking and is often disposed of in the kitchen sink. These materials stick to the pipe and accumulate as they travel downstream. To protect your home and the community, Do Not pour FOG down the drain.

Report Illegal Dumping

Illegal/illicit dumping is a major cause of sewer backups, treatment interference and water pollution. Public witness complaints provide the most common source of information. To report illegal/illicit dumping, call the GHID office 801-968-3551.

Commercial, Industrial, and Institutional Users

Granger-Hunter Improvement District has an active and ongoing Pretreatment Program. A key element of our Pretreatment Program includes our Staff working with our Commercial, Industrial, and Institutional customers to remove Fats, Oils and Grease (F.O.G.) and other pollutants from the public wastewater system. As part of our Pretreatment Program, we are encouraging all our customers to help keep these materials out of the public wastewater system. Please call our Pretreatment personnel at 801.955.2204 with any questions.

Best Management Practices

The wastewater produced by these business’s is unique to their type of work. Knowing and understanding Best Management Practices (BMP) for proper waste disposal can help reduce the size of your sewer bill.

What is a Grease/Sand Interceptor?

image of grease interceptor

A grease interceptor is a large device, (1,000 gal. minimum per GHID standards) that allows for the separation of pollutants from the water. As water settles in the tank, fats, oils and greases separate from the water and float to the top while sand, grit and other dense materials fall to the bottom. The clear water then flows through to the GHID sewer main. Bathrooms should not be connected to the grease interceptor.

Fixtures connected to grease interceptors are:

Commercial Users are inspected and sampled on a regular basis by GHID and CVWRF Pretreatment Staff to determine if the businesses are in compliance with these Pretreatment Rules and Regulations. You may refer to the GHID Wastewater Control Rules and Regulations tab for more information or call our Pretreatment personnel at 801-955-2204.

RV Dump Information

RV Dump Site -RV dump sites are intended for personal recreational vehicles only. Please report any commercial or suspicious activities to the District offices.

In accordance with GHID Pretreatment Rules and Regulations, the following substances are prohibited from being introduced into the publicly owned treatment works (POTW) (sanitary sewer collection system or treatment plant) at any point, including RV dump sites:

  1. Pollutants which create a fire or explosive hazard in the sewer system, including but not limited to, waste-streams with a closed-cup flashpoint of less than 140 degrees F (60 degrees C) using the test methods specified in 40 CFR 261.21;
  2. Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0;
  3. Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with a pH of more than 12.0;
  4. Solid or viscous pollutants in amounts which will cause obstruction of the flow in the POTW resulting in interference;
  5. Any pollutant, including oxygen-demanding pollutants (BOD, TSS, etc.), released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW;
  6. Heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the treatment plant exceeds 40 °C (104 °F);
  7. Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
  8. Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin exceeding 100mg/l;
  9. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
  10. Storm water, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized by the GHID;
  11. Hauled waste of any kind, including septic tank, grease interceptor and industrial waste.
