Water & Sewer Department

Water and sanitary sewer services are vital to maintaining a quality of life for our residents and commercial property customers.


The Village purchases Lake Michigan water from the City of Highland Park.

Sanitary Sewer

The Village of Deerfield provides the Village of Bannockburn with wastewater treatment. The Village of Bannockburn owns and maintains the sanitary sewer lines.

There are two sanitary sewer districts located in the Village of Bannockburn:

  • North Shore Water Reclamation District (NSWRD) – Residents in the NSWRD are invoiced by the Village of Bannockburn for the sanitary sewer lines that the Village of Bannockburn owns and maintains. The NSWRD also separately bills residents quarterly for the wastewater treatment. All properties in the NSWRD, whether served by sanitary sewer or not, have a charge included on their property tax bill from the NSWRD.
  • Lake County Sanitary Sewer System District – Residents in the Lake County Sanitary Sewer System District are billed by Lake County and do not receive an invoice for sewer from the Village of Bannockburn.9

Water & Sewer Billing

All customers share equally in the cost of operation, depreciation and debt service of the Village of Bannockburn water and sewer infrastructure. The Village of Bannockburn bills on a quarterly basis and the water rates are on a “tiered basis” (to help encourage water conservation). See Comprehensive Fee Schedule for current rates.

Invoices are mailed in January, April, July, and October. Payments are due 30 days after the invoice date. Check, cash or on-line payments received after the end of business on the due date will receive a 10% late penalty. If the due date falls on a weekend, payment is due no later than the close of business on the next business day.

Any customer that has incurred three (3) late payments within a two (2) year period may be required to pay to the Village a security deposit in the amount of the highest quarterly bill incurred within the last two years for the continuation of water services. The Village of Bannockburn reserves the right to discontinue service for non-payment of bill(s). A termination fee, a reconnection fee, and the total amount due including penalty (and deposit if required) must be paid before service will be resumed.

Payment Options

There are several payment options available:

  • Automated bill pay, direct debit, is the best way to ensure your bill is received by the Village in a timely manner. Auto Pay Application
  • Cash or check payments can be made in person at the Village Hall during normal business hours. In addition, there is a 24 hour mail drop located to the right of the front doors of Village Hall.
  • Credit cards may be used through the Village’s online payment website. Payments can be made by Visa, MasterCard, or Discover without a convenience fee. Credit cards are not accepted over the phone.

Village RPZ Requirements

Sprinkler Systems
In order to meet state mandates, the Water & Sewer Department keeps a list of all residences with underground lawn irrigation (sprinkler system). By law any homeowner with underground lawn irrigation is required to have a reduced pressure backflow preventer (RPZ) and have it inspected annually. This inspection ensures that no contaminated water will flow back into the Village’s potable water supply.

New sprinkler systems require a building permit from the Village of Bannockburn prior to installation. Please contact the Village of Bannockburn Building Department for information related to the requirements.

Annual Inspection & State Regulations
An annual RPZ inspection is required under the State of Illinois Plumbing Code 890.1130 (c). A certified copy of the report must be on file with the Village of Bannockburn. The Village requires that all inspections be completed and the report received no later than July 1st of each year.

The Village recommends regular maintenance be performed to sprinkler systems to avoid waste and maximize water use, avoid having sprinkler heads aimed at pavement areas, set your timers and use a rain shutoff device.
