When this guide fits

The water bill stayed high because sewer or wastewater charges are large, confusing, fixed, capped, or based on a separate average.

Sewer can be larger than the water usage charge. Some bills calculate it from current water use, while others use winter averages, caps, minimums, or fixed fees.

Check first

  • Find whether sewer is usage-based, fixed, capped, or averaged.
  • Check if irrigation or leak volume is excluded from sewer.
  • Compare sewer per CCF or per 1,000 gallons with the water charge.
  • Look for minimum sewer charges that limit savings.

Practical savings moves

  • Estimate water and sewer savings separately.
  • Ask about leak or sewer adjustments when a repair caused a one-month spike.
  • Reduce usage during months used for sewer averaging if the utility uses that method.
  • Use the sewer calculator before trusting a simple water-only estimate.

Avoid these mistakes

  • Do not assume every gallon saved lowers sewer.
  • Do not ignore minimum sewer charges.
  • Do not treat stormwater fees as sewer usage.

FAQ

Short answers for search visitors and bill-checking moments.

Why is sewer so high on my water bill?

Sewer may be billed from current water use, a winter average, a cap, a minimum, or a fixed monthly charge.

Do water savings always reduce sewer?

No. Sewer savings depend on the local billing method and whether sewer is usage-based for that water volume.
