Sewer System
The City operates and maintains 188+ miles of storm sewer and 169 miles of sanitary and combined sewers. Our work includes main line rodding and root cutting, main line televising, lift station operation/maintenance, catch basin cleaning, flood response and utility locating.
We also work collaboratively with the Metropolitan Water Reclamation District of Greater Chicago on various storm and sanitary projects, as well as monitoring the City’s connections with the District's system.
Note that Illinois American Water provides both water and sewer services for certain areas of Des Plaines. If you are located in this area, please contact Illinois American Water directly for questions about service or billing issues.
Sanitary Sewer Lateral Program
Sanitary sewer back-up? The Sanitary Sewer Lateral Program provides limited financial assistance to residents facing sanitary sewer complications within qualifying areas. A sanitary sewer lateral is the section of the homeowner's sewer line that runs from the house to the sewer main in the street, parkway or easement area.
If a Des Plaines homeowner experiences a sanitary sewer back-up, they could be eligible for financial assistance from the City (maximum of 30% reimbursement). The Sanitary Sewer Lateral Program provides financial assistance to residents facing sanitary sewer complications within qualifying areas.
Ownership and Insurance
The sewer lateral is owned and maintained by the property owner including any part that extends under the street or public right-of-way. The potential for property damage from sewer backups caused by damaged sewer laterals is something every Des Plaines homeowner needs to consider. Repair or replacement of damaged sewer laterals can cost thousands of dollars and typical homeowners insurance policies do not cover these costs.
However, sewer backup insurance coverage is available from most insurers as a “Rider” or “Endorsement” to your homeowner's insurance policy. These Riders may also cover the cost to repair or replace damaged sewer laterals. The City recommends you contact your homeowner's insurance agent regarding this type of additional coverage. Make clear that you are seeking sewer lateral repair or replacement coverage, as well as coverage for the cost associated with a sewer backup.
There are other third party insurance or warranty products on the market that provide coverage for sewer lateral repair and replacement. The City of Des Plaines cannot recommend any one company and advises residents to carefully research each company before making a decision.
Eligibility
If a Des Plaines homeowner experiences a sanitary sewer back-up, the following steps will help determine any work eligible for financial assistance (maximum of 30% reimbursement) by the City:
Step 1
Call the Public Works & Engineering Department at 847-391-5464 to inspect the sewer main and confirm that the main is not blocked and causing the back-up. The resident does not need to be present for this inspection. Any blockages discovered in the main will be cleared by the City. Public Works does not inspect/televise homeowner's lateral sewer lines.
Step 2
If the main is not causing the back-up, the homeowner will be directed to hire a sewer contractor/plumber to check their individual sewer line.
A listing of reasonably-priced sewer contractors is available from the City, by request. If the sewer contractor/plumber discovers a blockage within the right-of-way, the Plumbing Inspector must be contacted at 847-391-5380 to verify this determination.
If the blockage is within the City's right-of-way or easement and can be cleared, the homeowner will be eligible for a reimbursement of 30% of reasonable rodding costs, up to $100.
If the blockage cannot be cleared by rodding and the problem is within the right-of-way or easement, the Plumbing Inspector will make the determination to contact a City contractor or authorize the homeowner's plumber to proceed with the repairs at the homeowner's cost. Thirty percent (30%) of the total repair cost can be reimbursed to the homeowner, up to $4,000.
If the blockage is not within the right-of-way/easement, the homeowner is responsible for all costs. The homeowner is also responsible for all routine maintenance costs for the section of the sewer lateral not within the City's right of way/easement.
Questions regarding the Sanitary Sewer Lateral Procedure can be directed to the Plumbing Inspector at 847-391-5380.
