Inspection Chamber Grease

  • Pouring excess oil or grease down the drain is a big no-no. You should collect “yellow grease” in special bins for rendering by a third-party contractor. Scrape all extra grease and greasy food scraps off plates and cookware before using pre-rinse spray valve and dishwasher. Dispose of excess grease in the trash or recycle it as.
  • Polypipe underground drainage pipes and fittings are manufactured in the UK and hold all the relevant certificates and approvals, including BS EN 1401 and BS4660:2000 where applicable. The system is manufactured in PVCu to provide strength, durability and ease of installation, while our innovative seal and snap-cap system allows push fit joints throughout to further lighten the load.
  • Constant Level Lubrication Vented oilers, closed system oiler, and expansion chambers Oil Sampling Sampling ports, pitot tubes, vacuum pumps, and accessories Grease Lubrication Automatic grease dispensers, grease meter, and grease guns.
  • Positions in or close to inspection chambers or manholes (see paragraph 2.49) and to the foot of discharge and ventilating stacks. Bends should have as large a radius as practicable. 2.21 Drainage serving kitchens in commercial hot food premises should be fitted with a grease separator complying with prEN 1825-1 and designed in accordance with.


Inspection Chambers are not large enough for man-entry but allow the drain to be reached from ground level. Amendments to Part H of the Building Regulations that came into force April 2002 brought it in line with Table NB.2 of the British Standard for Drains and Sewers Systems Outside Buildings BS EN 752-3.

Fat, oil and grease (F.O.G.) interceptors required. Users who operate restaurants, cafes, lunch counters, take-outs, cafeterias, bars, clubs, or hotel, hospital, factory or school kitchens or other establishments that serve or prepare food where F.O.G. may be introduced to the sewer system shall have an F.O.G. interceptor.

Take-out food establishments or other establishments that prepare food but do not cook in oil or grease and who serve food only in disposable containers may utilize alternative interceptors as approved by the director, provided their discharges will not violate any discharge prohibitions of this article. F.O.G. interceptors may also be required in non-cooking or cold dairy and frozen foodstuff establishments when they are deemed necessary by the director.


Oil and sand interceptors required. Users who operate automatic and coin operated laundries, car washes, filling stations, commercial garages or similar businesses having any type of washing facilities or grease racks and any other users producing grit, sand, oils or other materials which may have the potential of causing partial or complete obstruction of the building sewer or other areas in the sewer system shall install interceptors approved by the director.


Location of interceptors. All interceptors shall be located outside the building in such a manner that personnel from CCU can inspect the interceptors at any time.


Size of interceptors. All interceptors shall be sized to ensure that the county's sewer system is protected from excessive F.O.G., sand and oil which may cause clogging or damage and that the user is capable of meeting all discharge requirements. F.O.G. interceptors shall be based on chapter 10 of the Florida Building Code, as amended.


Sampling port. A sampling port shall be installed in an approved location to allow sampling by the utility and the user. The sample port shall be located between the interceptor and the discharge point to the sewer system.


Access manholes. An access manhole must have a minimum diameter of twenty-four (24) inches and shall be provided over each chamber and sanitary tee. The access manholes shall extend at least to the finished grade and be designed and maintained to prevent water inflow or infiltration. The manholes shall have readily removable covers to facilitate inspection and cleaning.

Site plans showing the location of the interceptor, lines, clean out or manhole and sample port;


Details of the interceptor, lines, clean out or manhole and sample port; and

Formula and calculation used to determine the interceptor capacity.

Note: No non-grease-laden sources are allowed to be connected to sewer lines intended for grease, oil and sand separators.


Existing interceptors. All interceptors currently in use or in existence at the time of this article will be considered sized sufficiently provided they meet all discharge requirements as stated in this article. All new interceptors or interceptors to replace or upgrade existing interceptors will be required to meet all criteria stated in this division.

Inspections. When upon inspection the interceptor is found to have six (6) inches or more of solids in the bottom of the interceptor (using a sludge judge) or a grease cap of three (3) inches or more, or the establishment exceeds discharge compliance levels, the director can require a grease pump out. Upon completion of an on-site inspection or analytical results of sampling indicate a violation of this article, the director may issue a 'notice of violation' to the user or representative to document any discrepancies, noncompliance, special instructions or other guidance identified during the on-site inspection.




The user of the premises or business where such interceptor is located shall obtain from CCU a maintenance card which shall be posted in a conspicuous manner showing proof of regular maintenance. Such card shall be obtained annually and shall be presented upon request. All records pertaining to the maintenance of an interceptor shall be retained by the user for a period of not less than three (3) years and available to CCU upon request.


Every F.O.G. interceptor shall be cleaned every ninety (90) days or sooner, if needed. An exemption may be granted to the ninety-day minimum requirement if the user can establish that such maintenance schedule is not necessary.


Alternative treatments. The use of any free-enzyme, chemical, or other products designed to emulsify, liquefy or further render grease soluble for the purpose of clearing drains or circumventing the design of the interceptor is prohibited. All products claiming biological activity must be approved by the director. Approval for this or any other treatment does not relieve the user of properly maintaining the interceptor as to prevent discharge violations to occur.

Failure to comply with this section shall subject the user to appropriate enforcement, fines, and procedures as set forth in this article. Additionally, if any person fails to comply with this section and said failure results in damage to the county's system, the county shall be entitled to recover the cost of repair of the system from said person and any fines or penalties assessed against the county as a result of such failure.
