Livingston Regional Sewer System O&M Rate Calculation

        Did you ever wonder how your quarterly sewer O&M rate is determined?  Read on to gain  some insight!

First, one must understand how the system is managed.  Genesee County treats our wastewater and charges a rate per 1000 gallons for their service.  The Livingston County Drain Commission maintains our sewer system.  Their costs include infrastructure repairs, pumping station operation and maintenance, odor control chemicals, and other system management costs such as permits and inspections. Livingston County recovers these costs using a rate per 1000 gallons.  Tyrone Township charges a billing fee and administration fee.  A grinder pump maintenance fee is assessed to build a repair fund as a result of our conversion from STEP to grinder pumps.  This fee should go away in the next few years as a result of a sufficient reserve being built up over time.  Finally, a debt reduction fee is charged to current sewer users to pay down the excess bond debt resulting from only about 450 of the anticipated 2016 sewer users being hooked up to the system at this time.  Runyan Lake Members account for approximately 328 of the current sewer users.

All of these individual fees are plugged into the calculator below.  The formula assumes a residential wastewater generation rate of 207 gallons per day per household.  This measure is referred to as a Residential Equivalent Unit (REU).  We do not have individual meters on our homes so this rate is verified by taking the metered volume from Tyrone Township as it flows into the Genesee treatment plant, subtracting the commercial user flow (they have individual flow meters), and dividing the result by the total number of sewer users.  Any needed adjustment results in a modification to the calculated rate, which is reviewed by Tyrone Township annually.  Runyan Lake users have grinder pumps, thus the GRINDER rate applies for our O&M bills.

On 12/1/15 the Tyrone Township Board approved increases to our quarterly sewer O&M fees for 2016 - 2021 of approximately 3.5% annually.
