The District’s user charge consists of two components – a volume charge based on water consumption and a monthly service fee. Effective April 9, 2023, the volume charge is $2.25 per 1000 gallons of water consumption ($1.6831 per 100 cubic feet) and the monthly fee is $20.00 per account.
Commercial and industrial users may also be subject to a surcharge and a sampling and monitoring fee.
Our billing system automatically reviews residential meter readings, comparing winter and summer water usage. We will automatically limit your summer usage amount to 150% of your winter usage, and assume the metered water above that rate is being used for landscaping and not entering the sanitary sewer. If your summer meter readings are below 150% of your winter usage, you are billed for the amount of your actual summer usage.
The summer adjustment is applied during billing periods where the majority of the billing period is between April 15 and October 15.
Certain industrial and commercial customers discharge wastewater that has higher concentrations of pollutants than normal domestic sewage. In order to collect the revenue necessary to treat these higher strength wastes, we have a surcharge program.
We routinely collect samples to characterize the strength of the discharges from such customers, and bill them according to the results of the sampling.
Detailed information is contained in our Surcharge Program Information Sheet.
Some of our customers don’t send all of the water they use into the sewer system. We allow customers to install a separate meter dedicated to facilities where water is used but not returned to the sewer.
Customers who use large amounts of water for evaporative cooling, landscaping, or to produce a saleable product may find that it is economical to install a separate meter to measure these flows for credit. With an approved separate meter, we will adjust your bill to reflect only the amount of water that gets into the sewer.
If you are interested in this program, the first step is to complete and submit the Separate Meter form to apply for a separate meter. For residential customers with heavy summer use for landscaping, the summer adjustment program may already be providing a credit.
