Frequently Asked Questions about Connecting to the City Sanitary Sewer System
Why do I have to connect to the City sewer system?
Factors such as age of septic system, lot size, and soil conditions affect the quality of wastewater treatment. Code-compliant permitted septic systems can operate for 15 years or until they fail, whichever occurs first. Additionally, use of new technologies has made it possible to connect homes to sanitary sewer which in the past were not possible. Finally, State of Iowa septic regulations have changed considerably as a result of better understanding of how septic systems work and new technologies becoming available.
These are some of the reasons why in December of 1994, the City Council directed staff to enforce connection to sanitary sewers for properties that are within 200 feet of public mains.
Where do I start?
Obtain three bids from a plumbing or excavating contractor to connect your property to the City sanitary sewer and abandon your septic tank. If this price is less than 15% of the assessed value of your property, as shown in the records of the City Assessor, choose the contractor that you think will do the best job. You may ask the contractors for references to assist you in your decision.
The Bids should include the following:
· The cost for a plumbing contractor
· The cost for all excavation and backfilling operations
· The cost for all materials to completely install the new lateral and connect it to the city sanitary sewer
· Street pavement repair
· Plumbing and excavating permits
· Septic tank abandonment
If the bids are greater than 15% of the current assessed value as shown in the records of the City Assessor, contact Todd Irwin at the City of Dubuque, Engineering Department, 589-4270. You may be eligible for financial assistance with your project.
How much should I expect to pay to connect to the City sanitary sewer?
Several cost components are involved in connecting to the City sanitary sewer and every situation is different. The cost will be based on the difficulty and length of your new sewer lateral. The following are brief descriptions of the different cost components that you may expect to see on your project:
o The connection charge is a fee paid to the City prior to the start of the project. The fee is based on the amount of front footage that your property has and the new lateral length. Your connection charge and a map are enclosed.
o A licensed plumber must obtain a plumbing permit prior to starting your project. The permit cost should be included in the plumber’s bid. The plumber’s bid should also include all pipe, pipe fittings, labor and equipment necessary to completely install your new lateral and connect it to the City sanitary sewer.
o This is a cost that should also be included in the plumber’s bid. The excavator will need to obtain an excavation permit if work will be done within the City street right of way. The excavation price should cover all costs associated with excavating, backfilling, surface restoration and seeding.
Septic Tank Abandonment
The septic tank may either be completely removed or the tank can be pumped and the excavator can cave in the sides and backfill the area.
Is financial assistance is available?
The City has several financial assistance programs that may be available for you. One of the programs is for income-qualifying individuals, while another program is based on a maximum project cost (15% rule).
The City of Dubuque has established a maximum project cost cap of 15% of the current City Assessor property valuation. This means that the City may pay for any project costs over this cap and waive all or part of the connection charge. The City does limit it’s exposure to non-sewer costs such as landscaping, retaining walls, driveways, etc. These costs may not exceed 5% of the total project cost.
15% Rule Procedure
1) Contact the City Assessor to find out your current property valuation. If your low bid is greater than 15% of your current property valuation, contact Todd Irwin at the City of Dubuque, Engineering Division, 589-4270.
2) Submit three bids, for your sewer connection project to the Engineering Department for review. If it is determined that the construction costs do exceed 15% of your current property valuation, the Engineering Department will design, secure bids, and administer your project for you. This is done to help eliminate any inconsistencies in the bids.
3) Once the contract for your sewer connection project is awarded to the lowest bidder, you will need to provide the Engineering Department with a cashiers check in the amount of 15% of the current City Assessor property valuation amount. If there are non-sewer costs that exceed the 5% maximum, the amount exceeding the maximum will need to be added to the cashiers check or you may choose to do that portion of the work yourself.
4) As soon as the Engineering Department receives the check the contractor will be given notice to start.
