Overhead Sanitary Sewer Conversion Cost-Sharing Reimbursement Program
Who? Residents who are connected to a Northfield Township Sanitary Sewer System-maintained sanitary sewer with gravity sewer service susceptible to a sanitary sewer backup. Any resident who has converted to an overhead system including removal of all storm discharges to the sanitary system after January 1, 2011 is eligible for reimbursement.
Why? To provide financial assistance to residential homeowners who would like to modify their plumbing system to an overhead system to reduce the risk from sanitary sewer backups.
What does it involve? The construction of a sump pit under the basement or crawl space, an ejector pump and a watertight sewer line to connect to the existing gravity sewer service. In addition, the existing gravity service (unless in excellent condition) shall be rehabilitated by lining from the house to the Township sewer via a cleanout or by replacement. (The installation of a cleanout will be required if one is not currently present). Removal of all storm connections to the sanitary system (including but not limited to footing drains and storm sumps) is a requirement of this program. The Township's contribution will be 50% of the actual cost up to a maximum reimbursement of $7,500, based on a minimum of three estimates and homeowner approval of the contractor.
What costs are included?
- All material and labor costs necessary to convert the plumbing system to an overhead sewer including sanitary sump, pump, plumbing and ancillaries
- Installation of a separate storm sewer system to handle stormwater flows disconnected from the sanitary service or sanitary sump including storm sump, pump, plumbing and ancillaries as necessary
- Installation of a cleanout a maximum of 10 feet from the house. An additional cleanout is required every 80 feet if the sewer service is more than 80 feet in length
- Lining or replacement of the sanitary service from the home up and including the mainline connection
- Topsoil, sod, sidewalk, curb and gutter and road patch as necessary
What costs are not included?
- Permit fees
- Architectural fees
- Rodding and/or televising of the sanitary service
- Incidental costs such as interior redecorating – drywall repairs, paint, carpet and flooring
- Decorative exterior plantings (bushes, trees, plants etc) and hardscape (retaining walls, pavers)
The Steps Are:
- Submit an Overhead Sanitary Sewer Service Conversion Cost-sharing Application Form together with the following information/attachments:
a. Contractor's checklist (this will include certification from a licensed plumber that there are no stormwater connections to the service sewer or if present, they will be removed as part of this project)
b. Three (3) detailed written estimates from licensed Contractors to install an overhead sanitary sewer system, including disconnection of any stormwater connections and replumbing as necessary (a separate storm sump pump system may be required)
c. Certification that the sanitary sewer service is PVC and less than ten years old. If PVC, a DVD of sanitary service from home to mainline sewer connection is required
d. Three (3) detailed written estimates from licensed contractors to install a new sanitary service from the building connection to the main, in accordance with Township, Village and Cook County Codes or to line the sanitary service from the building connection to main including the installation of a cleanout. (Township may determine, based on its condition, that an older PVC service does not require rehabilitation)
e. Four (4) copies of construction plans and all necessary building/construction permit applications. (AlI inside plumbing work must be performed by an Illinois licensed plumber)
- Once permits are approved, Contractor may begin work but Homeowner must ensure that all inspections required by the Township are performed so that all the work is eligible for reimbursement. Work must be completed within 90 days of Township's approval being granted.
- On completion of the work, Homeowner shall submit to the Township the following:
a. Inspection checklist (to be prepared by Township and attached to approval notification)
b. Request for reimbursement form/checklist
