Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly; HWWS offers monthly electronic billing and monthly ACH bank draft.
- Rate structure
- The system uses adopted residential and commercial water and wastewater schedules with fixed charges plus volumetric consumption rates. HWWS approved a planned series of rate increases and states that the next scheduled increase is proposed for October 1, 2026; the accessible rate page does not render the complete table in text.
- Wastewater and sewer calculation
- HWWS publishes separate wastewater rates for residential and commercial customers. The accessible page confirms that the charge is based on the adopted rate schedule, but it does not expose the complete winter-average, monthly-consumption, or cap formula in text.
- Meter reading
- HWWS provides a public 'How to Read Your Meter' resource and bills monthly, but the reviewed pages do not identify the meter vendor, AMI/AMR communications technology, hourly transmission interval, or exact route schedule.
- New-account deposit
- Residential and commercial deposits start at $150.00. Residential applicants must present government ID, a matching Social Security card/passport/birth certificate, and a signed rental or purchase agreement; the security deposit plus service fee must be paid before release of the connection. Commercial deposits can be reduced by approximately 50% with a personal guaranty from a responsible owner or officer.
- Activation or transfer fee
- A next-day connection service fee is $15 and a same-day connection fee is $25. New connections are performed between 1:00 p.m. and 8:00 p.m.; the first bill must be paid in person or through the drive-through. Transfer-specific fees are not separately stated.
