Recommended Maintenance Activities
  1. Managers should always try to observe all interceptor cleaning/maintenance activities to ensure the device is properly cleaned and operational.
    Reason: Grease interceptor service companies may take shortcuts, and not completely clean the interceptor.
    Benefit: Witnessing this activity will ensure you are getting the full value for your money.
  2. Clean under-sink hydromechanical grease interceptors weekly. If interceptors are more than 25% full, increase the cleaning frequency.
    Reason: Weekly (or more frequent) cleaning of the hydromechanical grease interceptors by the facilities own staff will reduce the costs. If the facility does not have a gravity grease interceptor, the hydromechanical grease interceptor is the only means of preventing grease from entering the sewer system.
    Benefit: Cleaning under-sink hydromechanical grease interceptors frequently will reduce the frequency and cost of gravity grease interceptor cleaning and minimize odors.
  3. Clean gravity grease interceptors routinely.
    Reason: Gravity grease interceptors must be cleaned routinely to insure that grease accumulation does not cause the interceptor to operate poorly.
    Benefit: Routine cleaning will prevent plugging of the sewer lateral, and need to hire someone to unplug it.
  4. Keep a Maintenance Log.
    Reason: The maintenance log serves as a record of the frequency and volume of cleaning and maintenance, and helps insure the interceptor is cleaned on a regular basis.
    Benefit: The maintenance log will help with scheduling (frequency) of cleaning and will give the inspector evidence that proper & frequent maintenance is being provided in compliance with the sewer use ordinance section VI-6.
