Health Dept: Proper Grease Removal Methods

April 25, 2014

The Department of Health, in conjunction with the Corporation of Hamilton, issued a reminder for estaurants about how they can “properly dispose of their Fats, Oils and Greases and thus minimise the chance of effluent from the Seabright pipe binding together and washing in-shore in the form of greaseballs”.

The issue was spotlighted recently following the U.S. Consulate issuing a “Security Message” entitled “Contaminated Beaches,” citing the “ongoing dumping of raw sewage off Bermuda’s south coast.” Two weeks after that message was issued, ”greaseballs” washed up on the South Shore, with lumps scattered over beaches including Grape Bay.

The full statement is below:

The Department of Health, in conjunction with the Corporation of Hamilton, would like to remind restaurants about how they can properly dispose of their Fats, Oils and Greases (FOG) and thus minimise the chance of effluent from the Seabright pipe binding together and washing in-shore in the form of “greaseballs”.

Methods for proper FOG disposal are clearly mapped out in the City of Hamilton Council Policy, which is available by contacting either Patrick Cooper at pcooper@cityhall.bm or Ian Hind at ihind@cityhall.bm or by calling 292-1234.
‘FOG’ is introduced primarily from restaurants that prepare and serve large volumes of food.

Once in the sewer system, FOG can clog sewer lines as it collects and coats the pipes, and this coating can get as hard as concrete. Over time sewer pipe flows can be restricted and the lines can even seal up completely.

The restricted flow can cause the sewer system to back up, resulting in a sanitary sewer overflow (SSO), where the sewer water flows out of a manhole cover and along the ground. These overflows can then contaminate the ground, the storm drain system and any property that it comes into contact with.

The City of Hamilton Council Policy States: “The improper management of FOG is not only a hazard to the environment and potentially the public’s health, it also results in added financial burdens to both food service establishments and the City of Hamilton. Lines clogged with FOG deposits require cleaning by the food establishment when it involves business-owned pipes and by the City for sewer system pipes.”

The City of Hamilton Council Policy is applicable to all non-residential premises connected to the sanitary sewer collection system involved in the preparation or serving of food. It covers effective methods that can be employed at the food service establishments to prevent significant amounts of FOG from flowing through and clogging the disposal pipes.

These methods involve the capture of the FOG, and disposal of the FOG or collection for recycling. The City has the authority of requiring businesses to practise these methods of FOG discharge control.

All permitted food service establishments discharging wastewater to the City of Hamilton’s sanitary sewer collection systems are subject to the following requirements:

  • 1) All permitted food service establishments are required to install, operate, and maintain an approved type and adequately sized grease interceptor. A grease interceptor is a structure or device designed for the purpose of removing and preventing FOG from entering the sanitary sewer collection system. These devices are often below-ground units in outside areas and are built as two or three chamber baffled tanks. All grease interceptors must be approved by the City Engineer.
  • 2) All grease interceptors shall be readily and easily accessible for cleaning and inspection. Grease interceptors shall be installed unless the City Engineer authorizes the installation of an indoor grease trap or other alternative pre-treatment technology and determines that the installation of a grease interceptor would not be feasible. The grease interceptor may not be installed in any part of the building where food is handled. Location of the grease interceptor must meet the approval of the City Engineer.
  • 3) No User shall allow wastewater discharge concentration from the grease interceptor, grease trap or alternative pre-treatment technology to exceed 100 milligrams per liter2, as defined by method EPA test method1664.
  • 4) All such grease interceptors shall be serviced and emptied of accumulated waste content as required. Grease interceptors shall be kept free of inorganic solid materials such as grit, rocks, gravel, sand, eating utensils, cigarettes, shells, towels, rags, etc., which could settle into this pocket and thereby reduce the effective volume of the device. The User shall maintain a written record of inspection and maintenance for three years. All such records will be made available for on-site inspection by a representative of the City of Hamilton during all operating hours.
  • 5) Upon approval by the City Engineer, a grease trap must be installed in the waste line leading from sinks, drains, and other fixtures or equipment in food service establishments where grease may be introduced into the drainage or sewage system in quantities that can effect line stoppage or hinder sewage disposal. A Grease Trap is a device for separating and retaining waterborne greases and grease complexes prior to the wastewater exiting the trap and entering the sanitary sewer collection system. Such traps are typically compact under-the-sink units that are near food preparation areas.
  • 6) Grease traps shall be maintained in efficient operating conditions by periodic removal of the accumulated grease. No such collected grease shall be introduced into any drainage piping, or public or private sewer. Wastewater in excess of one hundred-eighty (180oF) shall not be discharged into a grease trap.
  • 7) Food waste disposal units are prohibited from being connected to the sewer. The decision to connect dishwashers to a grease trap will be made by the City Engineer on a case-by-case basis.

    The government should look into creating a bio diesel processing plant. Make it mandatory for all restaurants to bring them their used cooking oil so it can be turned into diesel. The government can then use it to power all their diesel vehicles and equipment. Saving taxpayers money.

    • Mike Hind says:

      That’s a really good idea!

      Even better, a private company or person should look into it!
      It’d probably make some money!

      • Toodle-oo says:

        It’s already been done before by two different people . One at Southside and one up at SAL West a few years ago.
        I have a strong feeling that both of them are no longer doing it .
        One would think that with all of the ‘free’ used cooking oil available locally even if it’s an expensive procedure it ought to be viable.

        One West End farmer used to run his equipments on the stuff and if I got caught behind one of his trucks or tractors it was a breath of fresh air compared to them being run on regular diesel.

        • micro says:

          Not all that expensive, especially with simpler diesel engines, filter out the solids and pour the oil straight into the gas tank, nothing fancy to be done. It is less efficient to run tho.

  2. Terry says:

    With all these job loses et al an idea.
    PWD/Old water trucks……
    If there is a method and not via the sewage system…..suck it up.

    Transport to a site etc.
    Of course this would involve a few dollars and access to a ‘holding tank- or even barrel.

    Food for thought and not for fishees.
    Shalom.

  3. Truth is killin' me... says:

    When’s the last time an inspection on a grease interceptor or grease trap at a restaurant in Hamilton been done!?

    • Terry says:

      Ask the Minister.

    • Evie says:

      Give them a reasonable amount of time to bring their restaurants up to standard then they need to fine all restaurants for not installing the proper equipment in their establishments why should the government supply this for these business

    We need a grease Czar!

  5. Plane to sea says:

    I would be supprised if you didn’t find the coveluted diatribe from cabinet house for sale in written form at the dollar store soon….were heavely invested in their goings on weather we like the thought orfamiliarity with it or not…

  6. Plane to sea says:

    They could actually use it as a lubricant in somerset …or st. Georges…

  7. Plane to sea says:

    You could call it tunnel o’ luv…

  8. Peggy says:

    Spent a lovely afternoon at Grape Bay yesterday. No grease balls in sight and children wading in the surf. I have been swimming at that beach since I was a child as did my father before me. No health issues!

  9. John says:

    What about the partly treated sewage that comes from the hotels? None have a FULL and up to date sewage plant. In fact none exist on the whole island. It is suppose to go thru 12 different processes b4 being pumped out to sea. We have only the first three. I’m more worried about swimming in $*** water than greas water!! Why is there no mention about the hotels? Most beaches u can dive under and find grey spots of sand which stink. We been swimming in our s*** for a long time and eating the fish that ingest it. I’m happy it’s finally been brought to the publics attention
