Homes constructed prior to the early nineteen-sixties were installed with gravity sewer systems that make their basements more susceptible to flooding from sanitary sewer backups; especially during heavy and extended rain falls.
During intense rains, the capacity of the sanitary sewer system, at times, is not adequate to carry the peak flow, resulting in pressurized sewers. When pressurized, sewage can backflow through house sewers into basements if there is no backflow prevention device.
The Overhead Sewer and Flood Control Device Assistance Program was authorized to offset a portion of the expense homeowners will incur to revise the house plumbing such that sewage cannot backflow into the house when the combined sewer is pressurized. There are three basic options available to a homeowner as listed below:
1) Modification of the plumbing stack to direct the flow out of the house in a new OVERHEAD SEWER and elimination of all gravity drainage below the basement floor slab.
2) Installation of an interior or exterior BACKFLOW PREVENTION VALVE and bypass pump on the house lateral in an underground vault.
3) LIFT STATION system within an inside or outside underground vault.
Each approach has different costs and degrees of homeowner disruption, as well as different implications on the homeowner’s use of the revised plumbing.
It should be noted however, Option 1 above, the installation of a new overhead sewer, is strongly recommended to provide the greatest protection available under all weather conditions and storm events to prevent sewage from entering the home.
This program does not include updating or enhancements current systems, however, the Public Works Department will inspect your current system for free. If you have an old system and choose to replace the entire system then this program will help cover these costs.
Goals and Objectives
This program has several goals. The primary goals are to provide protection from the back up of sewage into basements, increase property values by eliminating detrimental basement back up, eliminate unsafe sanitary conditions, and to save substantial taxpayer dollars in the long term.
Residential properties in Morton Grove’s corporate limits constructed prior to 1965, when building codes were revised and required overhead plumbing, are eligible for the Overhead Sewer and Flood Control Device Program.
1. The Overhead Sewer and Flood Control Device Program is limited to conversion of sanitary sewer gravity systems.
2. Eligibility for the Overhead Sewer System conversion will be contingent upon the perimeter footing drains, driveway drains, outside stairwell drains, downspouts and any other ground water source not being connected to the sanitary sewer system.
3. For properties that currently have perimeter footing drains, driveway drains, outside stairwell drains, downspouts, and any other ground water source being directly discharged (i.e., connected) into the sanitary sewer system. The property owner must submit confirmation that the above footing drains, driveway drains, outside stairwell drains, downspouts, and any other ground water source shall be disconnected from the sanitary sewer system per Title 7 (7-5-4A) of the Municipal Code and the installation of a separate storm sewer system (i.e., Sump Pit and Pump) to handle these extraneous flows must be included as part of the proposed work with the Overhead Sewer System conversion proposal.
4. Eligibility for the Flood Control Device conversion will not be contingent upon separation of footing drains at this time, but may be required in the future.
5. The individual seeking participation in the Overhead Sewer and Flood Control Device Assistance Program and seeking Village reimbursement must establish they are the owner of the property for the proposed modification of their plumbing system. Participation in and reimbursement through this Overhead Sewer and Flood Control Device Assistance Program is limited to one time only per address.
6. The property owner must complete and submit an Overhead Sewer and Flood Control Device Program Application Form. A representative from the Public Works Department will perform an on-site inspection to determine if the property is eligible for this program. When a property is approved for the Overhead Sewer and Flood Control Device Assistance Program a “Notice to Proceed” will be issued in writing by the Village, the property owner will have 90 days to complete the project. The 90 day time frame commences with the Village’s letter acknowledging this sewer work is eligible to participate in the program.
7. The property owner shall obtain three written detailed proposals from three (3) Illinois licensed contractors that have not been barred from doing business in Morton Grove. The property owner shall submit a copy of the three (3) proposals to the Public Works Department at the time the assistance is applied for.
8. The property owner shall contract with the plumbing firm for the overhead sewer or flood control device and obtain all required Village permits. All plumbing work must be performed by a licensed plumber. All work must conform to the Village’s Building Codes and related sections of the Morton Grove Municipal Code.
The program is on a first come, first serve basis and applications received will be prioritized and authorized based on availability of the Village funding.
The Village reserves the right to alter, postpone or cancel the program from year-to-year as funding is dependent on budgetary and financial constraints of the Village.
1. Loans from the Village for properties that pre-qualify for the Overhead Sewer and Flood Control Device Assistance Program will be processed only upon completion of all work.
2. Loans made by the Village will be limited to 50% of the actual contractual construction cost, up to a maximum of $5,000. If the property owner selects a plumbing firm other than the lowest estimates, then the Village’s contribution will be limited to 50% of the lowest bid amount, up to a maximum of $5,000. The property owner shall sign a promissory note and property lien for all amounts borrowed. The note and property lien provides that the loan shall not bear interest unless the property owner fails to repay the loan when due. The loan shall be due upon the sale of the property or the ten (10) year anniversary of the execution of the loan documents.
3. The property owner must submit to the Public Works Department verification of all required inspections and final approval of the completed improvements by the Village’s Public Works Department; a copy of the licensed plumber’s as-built, signed and dated plans (with plumber’s state license #); and proof of payment in the form of paid receipt and contractor’s waiver of lien.
Village shall make payments to applicants only, not to contractors or suppliers.
