How this utility’s billing works
Suffolk County Water Authority (SCWA) operates as a public water authority serving Suffolk County, Long Island. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Quarterly fixed service charge plus metered consumption in CCF. The published schedule lists a $34.33 quarterly service charge, a standard $1.866 per CCF rate through 120 CCF per quarter, and a conservation rate of $2.694 per CCF on usage above 120 CCF for meters up to one inch; larger meters use separate thresholds..

These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
SCWA is a drinking-water authority and its published household rate schedule is for water service; it does not establish a universal sewer calculation for every Suffolk County municipality. Wastewater, if applicable, is billed by the local sewer district or municipality and may use a separate flat, metered, or seasonal formula.
Meter and infrastructure notes
SCWA bills quarterly and maintains meters and remote-reading devices; the schedule says meters and remote reading devices remain SCWA property. The reviewed pages do not state a universal hourly AMI transmission schedule, but customers can use bill usage history and SCWA's high-bill tools to diagnose readings.
