The Forgotten Line Items

First-time buyers budget for the mortgage. Experienced buyers add insurance and taxes. Almost nobody budgets for water, sewer, and trash — until the first bill arrives.

National averages:

  • Water: $45/month
  • Sewer: $50/month
  • Trash/recycling: $35/month
  • Total: ~$130/month or $1,560/year

That’s $46,800 over a 30-year mortgage. It belongs in your housing budget.

Why Costs Vary So Much

Water and sewer rates are set by local municipalities, not state or federal agencies. This creates enormous variation even within the same state.

High-Cost Drivers

  • Aging infrastructure: Cities with 100+ year-old pipe systems (Northeast, Midwest) charge more to fund replacements
  • Water scarcity: Western states (CA, AZ, NV) price water to discourage consumption
  • Combined sewer systems: Older cities where stormwater and sewage share pipes face EPA consent decrees requiring billions in upgrades
  • Low population density: Rural areas spread fixed infrastructure costs across fewer customers

Regional Patterns

  • Northeast: $150-$200/month combined (aging infrastructure, regulatory compliance)
  • Southeast: $100-$140/month (newer systems, lower labor costs)
  • Midwest: $110-$150/month (infrastructure age varies widely)
  • West: $120-$180/month (water scarcity premiums)
  • Pacific NW: $130-$160/month (stormwater management costs)

The Rising Trend

Water and sewer rates have increased an average of 4-6% annually for the past decade — double the rate of general inflation. The American Society of Civil Engineers estimates the U.S. needs $600 billion in water infrastructure investment over the next 20 years. Those costs are funded by ratepayers.

Trash collection is also rising, driven by labor costs and the collapse of recycling markets after China’s 2018 import restrictions. Some municipalities have switched from tax-funded to fee-based trash, creating a new monthly bill for homeowners.

Well Water and Septic: Different Costs

Well Water

Roughly 13% of U.S. households rely on private wells. No monthly water bill, but maintenance costs include:

  • Water testing: $50-$200/year (recommended annually)
  • Well pump replacement: $1,500-$3,000 every 10-15 years
  • Water treatment/filtration: $500-$3,000 to install, $200-$500/year for filters
  • Well problems (low yield, contamination): $3,000-$10,000+ to resolve

Septic Systems

Roughly 20% of homes use septic systems. Costs:

  • Pumping: $300-$600 every 3-5 years
  • Inspection: $200-$400 (required at sale in many states)
  • Drain field repair: $5,000-$15,000
  • Full system replacement: $15,000-$30,000

A failed septic system can make a home uninhabitable until repaired. This is a critical inspection item when buying in rural areas.

How to Research Before Buying

  1. Ask the seller for 12 months of utility bills — not estimates, actual bills
  2. Call the municipality and ask for the rate schedule plus any planned increases
  3. Check for special assessments — some areas levy water/sewer improvement assessments against properties
  4. For well/septic: Get professional inspections and ask when the well was last tested and the septic was last pumped

HomeStats now includes estimated water, sewer, and trash costs by state in the Cost of Ownership section on each state page, factored into the total annual ownership cost.

The Resale Trap covers every utility cost category and provides a pre-purchase checklist for evaluating a home’s true operating costs before making an offer.
