Fats, Oils and Grease Control Program

The Hi-Desert Water District's (District) Board of Directors (Board) has adopted Resolution 21-09, a Fats, Oils and Grease (FOG) Control Program (Program). This Program requires all commercial businesses to complete an Application for Inspection prior to the operation and discharge of FOG into the District's new wastewater collection system. Failure to complete an application can lead to enforcement actions.

The FOG Application for Inspection process is comprised of six(6) steps:
  1. Application. The application can be completed online here. Or you can download a hardcopy here to complete and mail in.
  2. FOG System Evaluation. FOG Compliance Inspectors will review your establishment's application and determine if an inspection is needed.
  3. Payment. If District Inspectors determine an inspection is needed you will be directed to pay the $100.00 inspection fee.
  4. Inspection. An Inspector will visit your establishment. Compliance status is determined by visual inspection of the pretreatment system, interview with the owner/staff about general operations and waste handling; and a review of documentation of pretreatment system maintenance, pretreatment system waste disposal and employee training.
  5. Refunds. Any commercial property, that is deemed, after the initial inspection, to not require a FOG permit, will be refunded the $100.00 inspection fee.
  6. FOG Permit and Compliance. After passing the inspection, your establishment will receive a Discharge Permit. This permit must be renewed every 12-months and an annual $120 fee is charged.
Failure to comply with the District's Program means District Inspectors may issue administrative fines of up to $1,000 per-violation, per-day. Unpaid charges, fines and penalties, may, after thirty (30) calendar days, be assessed an additional penalty of ten percent (10%) of the unpaid balance.

To renew your Permit complete the annual renewal application here.
