One of the most important functions of the Public Works Department is to ensure the quality of our water supply. The Village receives its drinking water from Lake Michigan and stores the water in tanks throughout the community. This ensures our residents and businesses have abundant access to healthy, quality water.

The Village also is responsible for managing storm water run-off. When it rains, water washes over roofs, streets, driveways, sidewalks, parking lots, and other surfaces. Along the way, it can pick up a variety of pollutants, such as oil, pesticides, metals, chemicals, and soil. This polluted storm water drains into the storm system that eventually discharges into our rivers and streams. The pollutants can endanger the water quality of our waterways, making them unhealthy for people, fish, and wildlife.

Conserving Our Water - Protecting Our Environment

Storm sewer inlets are the manholes with large openings allowing storm water run-off to drain away from your house and other property. Unlike sanitary sewers, the water that the goes into storm sewers is not treated before being released into lakes, rivers and streams.

Our rivers and lakes provide the water we drink. You are our partner in preserving our water supply! Here’s how you can help:

• Use a mulch mower, but remember to remove grass clippings and leaves from driveways, sidewalks, curbs and gutters to prevent the materials from washing into storm sewers.
• If you live along a pond, Poplar Creek or Arlingdale Lake, leave a buffer along the edge. Buffers filter nutrients and keep dirt, grass clippings and other materials from going into the water.
• Avoid washing your car in your driveway. Wash in a grassy area or take it to a local car wash. Local car washes are connected to the sanitary sewer, so any soap, grease, oils, and other contaminants do not go into the storm sewer system.
• Please don't litter; pick up and properly dispose of litter.
• Pick up all pet waste either when you’re on a walk or in your yard. Pet waste is a leading cause of local run-off pollution.
• Plant native trees, shrubs, grasses, and wildflowers. They require less watering, little or no fertilizer, and provide habitat for wildlife.
• Cover exposed soils to prevent erosion. Exposed soils have the greatest potential for wind and water erosion.
• Direct your downspouts to grassy areas.
• Recycle car batteries at the Public Works Department. Drop off car batteries at Door #14 during normal business hours (8:00am – 4:30pm, Monday-Friday)
• Never dispose of oils, chemicals or other garbage in the storm sewers. This is like pouring garbage into your drinking cup.

Green Infrastructure Policy

Our Green Infrastructure Policy directs the Village of Streamwood to continuously look to reduce runoff flow rates and minimize pollutant loads entering the storm water system and waterways.

Commercial and Residential Water Application

As a new business owner or residential tenant within the Village, we request that you fill out an application for water and sewer service. This is mandatory so we can provide you with quality service. You can download a copy of either the Commercial Water Application Form or the Residential Tenant Water Application Form.

Report Broken Water Mains

If you see a quantity of water coming out of the ground, it may be a broken water main. Please report broken water mains by calling the Public Works Department during normal business hours, or the Police Department at 9-1-1, on nights or weekends. Leaking fire hydrants should also be reported to Public Works or the Police.

Water System Management

The Public Works Department maintains the water storage tanks and distribution system. The primary source of drinking water is Lake Michigan. The Village is a member of the Northwest Suburban Municipal Joint Action Water Agency. Each year, the Village publishes a Consumer Confidence Report that explains in greater detail the water supplied to our residents. View our current Water Quality Report. The City of Chicago also performs a Comprehensive Chemical Analysis.

The Illinois Environmental Protection Agency (IEPA) also requires the Village to have an effective Cross Connection Control program. Cross connections within the public water supply are a serious concern as they can allow contaminants to 'backflow' into the water supply. Backflow preventers, or Cross Connection Controls, help keep our water system safe. The Village also conducts periodic surveys of backflow preventers within the community. Backflow preventers must be tested regularly. The Village works with Aqua Backflow, Inc. to monitor and manage this testing and required IEPA reporting program. Questions on this testing program should be directed to Aqua Backflow, Inc. at (847) 742-2296.

Storm Water Pollution Prevention

The Village of Streamwood discharges storm water from its storm sewer system under the IEPA General National Pollutant Discharge Elimination System Permit No. ILR40.

As a condition of the permit, the Village is required to implement Best Management Practices for a five-year period in order to reduce pollution to the receiving waters.

After each program year, the Village must document its status of compliance with, and any changes to, the permit in an annual Facility Inspection Report. Below is a list of recent reports:

• 2023 - 2024 Annual Report
• 2022 - 2023 Annual Report
• 2021 - 2022 Annual Report
• 2020 - 2021 Annual Report
• 2019 - 2020 Annual Report

Storm Water Management

The Village of Streamwood's General Permit No. ILR40 requires the Village to develop, implement and enforce a storm water management program designed to protect water quality and prevent and reduce pollution from its storm sewer system to the maximum extent practicable.

• Storm Water Management Plan

To comply with ILR40 Permit requirements, the Village Code and the Cook County Watershed Management Ordinance, along with the Annual Facilities Reports, are designed to provide the IEPA and the residents of Streamwood with an understanding of the measures the Village employs to ensure public health and safety by reducing pollution into the receiving waters.

This is achieved through the implementation of six minimum control measures and related best management practices (BMPs) for each. More details are located in the Village's annual reports.

• Current Storm Water Notice of Intent Activities
