Water service charges are calculated on the basis of metered water usage or the minimum bimonthly usage, whichever is greater. The customer is responsible for all water usage on the property as measured by the meter. It is advisable to keep your plumbing in good repair (i.e.:no leaky faucets or running toilets, etc.) to keep your charges as low as possible.

Sewer user charges are calculated on the basis of metered water usage or the minimum bimonthly usage, whichever is greater. To allow for water consumption which is not ultimately discharged into the sanitary sewer system, a maximum sewer service charge shall be established on an individual basis for single-family residential customers only. For four (4) summer months, the maximum sewer service charge shall not exceed one hundred-seventy-five percent (175%) of the average consumption for the previous eight (8) "non-summer" months. Each customer's base usage is recalculated each year using the previous "non-summer" months. Please contact the Warren County Water & Sewer Department to determine the applicable summer months for your service area.

For new homes or new accounts resulting from transfer of property for which less than three (3) bimonthly readings are available during the "non-summer" months, the average usage of the area is used as the basis for calculating base usage.

The following is an example of a calculation of the summer sewer use charge for last summer:

  • Example:
  • Assume that the average water usage for eight (8) months non-summer base period is 12,000 gallons per billing cycle or, for a 60-day cycle, 200 gallons per day. If a summer billing cycle is 62 days, the base usage would be 12,400 gallons (62 days x 200gpd). All sewer usage up to 21,700 (175% of 12,400 gallons) would be billed at the normal rate stated above. All usage in excess of 21,700 gallons would not be subject to sewer user charges.
