Sewer Maintenance

The Public Works Department operates a wastewater utility that supplies residential, commercial, and industrial customers through over 2,200 connections. The City operates and maintains its own wastewater treatment plant, and collection system.

HOW TO REPORT SEWAGE OVERFLOWING FROM A SEWER MANHOLE OUT IN THE STREET

Immediately contact the Public Works Department at (209) 874-4095 or City Hall at (209) 874-2328. We will determine the cause and remedy the situation.

FATS, OILS, AND GREASE

FOG refers to Fats, Oil and Grease originating in most kitchens, restaurants and food service establishments. As a byproduct of cooking, FOG is usually found in:

  • Cooking Oil/Butter/Margarine/Lard
  • Meats
  • Dairy Products (Milk, Cheeses, Yogurt)
  • Sauces/Gravies/Salad Dressings
  • Deep-Fried Dishes (French Fries, Fried Chicken)
  • Baking Goods (Pizza, Cookies, Pastries)
  • Food Scraps

FOG CLOGS SEWERS!!

FOG is washed into sewers mainly from food preparation      establishments (usually through kitchen sinks and floor drains) that do not have adequate grease control measures in place. FOG attaches to the inner lining of the private plumbing system on your property, as well as the public sewer system in City streets.

With time, the FOG buildup can constrict flow and eventually block the entire pipe, causing sewage backups and overflows. A sewage overflow will find its way from the street level into the storm drain, which finally leads to the river.

OTHER POTENTIAL COSTS AND CONSEQUENCES OF FOG?

  • Property Damages from sewage backups. You have to pay for expensive cleanup and plumbing repairs!
  • Health Hazards from insect infestation. Backed-up sewage and accumulated food residue are perfect breeding grounds for bacteria, insects and other vermin.
  • Monetary Penalties from non-compliance. Most municipalities either presently or plan to pass the cost of clearing blockage, cleanup and any regulatory fines assessed back to the offending party.
  • Business Closure from health code violation. This could greatly impact your business operation!
  • Increased Sewer Fees from City’s excessive maintenance and severe fines from regulatory agencies. FOG blocks sewer pipes, gums up pump stations and interferes with the normal operation of wastewater treatment facilities.
  • River Closures from high bacteria levels in contaminated storm drain flows. Overflowed sewage will contaminate the flow in the storm drain and cause health risk concerns for swimmers and animal life.

KEEP FOG OUT OF THE SEWER SYSTEM AT THE SOURCE

Implement the following Best Management Practices:

  • Install a properly sized grease trap/ interceptor to handle the anticipated amount of FOG.
  • Properly operate and maintain the grease trap/interceptor. Clean and service the grease traps/interceptors regularly and frequently.
  • Use less oil.
  • Use liquid oil instead of solid grease or lard.
  • Dry wipe or scrape grease and food scraps from dishes, pots, pans, utensils and grills (or other cooking surfaces) into a can or the trash for disposal before putting them in the sink or dishwasher.
  • Do not put grease down garbage disposals. Use baskets or strainers in sink drains to catch food scraps and other solids and dispose of it in the trash.
  • Collect and dispose used oil through a licensed grease hauler instead of pouring it into kitchen sinks, floor drains or toilets.
  • Capture the oil accumulated in ventilation and exhaust hoods.
  • Be cautious of those chemicals/ additives that claim to dissolve grease, including soaps and detergents. They may pass grease down the pipe and clog the lines in a different area.
