Where does utility provider data come from?

Utility data is compiled from Census Bureau ACS housing data (heating fuel, costs), EPA Safe Drinking Water Information System (SDWIS) for water systems, and state utility commission records. Provider names and service areas come from utility filings and municipal records.

What is included in monthly housing costs?

Census Bureau housing cost data includes mortgage or rent payments, property taxes, insurance, utilities (electric, gas, water, sewer), and condominium fees if applicable. The median housing cost gives a typical monthly total for homeowners or renters in the municipality.

How do I find out who provides my water?

Your water provider is typically the municipal water department or a regional water commission. Check your water bill for the provider name, or search the EPA's SDWIS database. This page lists all public water systems serving this area along with any violations.
