1. I don't receive a bill from ISD. How am I charged for my sewer service?

Unlike many public utilities, Ironhouse Sanitary District assesses its customers annually through property tax bills. The fee you pay is determined by the type of property you own. You divide the amount by 12 to determine the monthly rate. For a current list of rates, please see our rate information page.

2. How does ISD determine sewer charges?

The district's sewer service charges are designed to recover the cost of service based on long-term operating and capital funding requirements. The district bills residential customers a flat annual rate per dwelling unit and collects the sewer service charge on the property tax bill. Non-residential customers are billed based on the number of equivalent service units (ESUs) assigned to each customer. An ESU represents the wastewater discharge from a typical residential dwelling unit. The District assigns ESUs to non-resident customers based on estimated volume and strength of each customer's wastewater discharge in relation to that of a typical residence. To see how ratepayers' tax dollars are being spent, ISD has provided a copy of the annual budget for rate payers to view.

3. What if I have questions on my ISD rate on my tax bill?

1. I own a septic tank, but I've noticed that recently a new subdivision went up in my area and I am wondering if now I can connect to ISD's sewer line?

With the pace of development in our service area it is possible that you may be able to connect with ISD as our trunk line is extended to accommodate the growth. If you are eligible you must pay a one-time hook-up fee in addition to the annual fee assessed on your property tax statement. For current connection fees, see our rate information page.
