A. There shall be no hookups or provisions made of unimproved lots.
Q. How large an easement will be needed from each property owner?
A. The easement width will be 5’ on both sides of the structure (service line from grinder station to mainline, electric connection from house to the grinder station, neighbors 4” service line if required or a radius of 5’ from a point such as a grinder location. “Main Collector Lines” shall have an easement width of 15’ on both sides of the structure as installed unless otherwise stated.
The easement for your 4” service line from your house to the grinder station or where it exits your property will be a temporary easement and will expire once construction is complete. The homeowner will be responsible for the repair and maintenance of the 4” service line after construction.
Q. Easement across lot for piping, what about access to piping?
A. Yes, will be described in the easement agreement.
Q. Are the easements temporary or permanent?
A. For the most part easement shall be permanent. The Easement for connection to your house shall be temporary along with any temporary construction easement that may be required.
Q. Where does it guarantee that property will be put back into original condition after work is completed or repairs must be made?
A. Defined in the Project Specifications and easement.
Q. Can homeowner amend easement document?
A. Yes, there is a place for special provisions.
Q. What is the estimated monthly cost per homeowner?
A. Current rate for residential is $63.00. However, we are still working with the funding agencies and this bill may fluctuate slightly up or down.
Q. How will these funds be collected?
A. The District will provide billing and collections for all of its customers.
Q. What are the guidelines for increasing sewer fees each year?

Contractors: During Construction
Q. Who will be assigned from Shoreline Surveying & Engineering for on-site inspection of the sewer installation?
A. A project inspector will be assigned for installation inspection. This person must inspect and document all work before it is covered. Tony Cobb, SSE will also be available as a coordinator for any installation concerns, questions, or problems.
Q. How does homeowner contact contractor if a dispute comes up with the construction crew?
A. Contact should be to Tony Cobb at SSE, cell phone 573-480-5405, or Jared Wheaton, cell phone 573-714-0366.
Q. What will the contractor be instructed to do about any sewer lines near water lines? How will exceptions be handled? (i.e. Sewer too close to waterline. Will sewer be encased in concrete?)
A. All defined in Project Specifications. Typically there must be a ten (10) foot separation laterally and eighteen (18) inch separation vertically. This is part of the project inspector’s assignment.
Q. Who will inspect system before ditches are backfilled?
A. Shoreline Surveying & Engineering project inspector.
Q. Can homeowner stop installation if a dispute comes up? (i.e. Backfilling without proper pipe bed?)
A. No, homeowner should contact project inspector.
Contractor must warranty system for one year after GASD accepts the complete system. After one year GASD maintains system. Homeowner is responsible for sewer line from home discharge to pump tank.
Q. How is repair handled? Who to call, GASD or service company?
A. Homeowners will be given an adhesive label for grinder pump electric box. This will list the phone numbers of the service company and GASD?
Q. Will there be a time standard for a service call?
A. Same day or within 24 hours.
Q. What happens if a homeowner refuses to participate in the sewer system?
A. Because of the time constraint due to the project funding there will not be time for condemnation, which is typically what would happen. In this case, the homeowner will be bypassed at the time of construction. Homeowners should be aware that the District has mandatory connection. Once the mainline is built and sewer is available the District will enforce the mandatory connection and the cost of the connection, including all equipment and materials, will be the responsibility of the homeowner. In most cases, this will be in excess of $10,000 worth of equipment.
Q. What happens to the sewer system when the electricity goes off for two (2) or three (3) days due to severe winter storms?
A. Tank holds 320 gallons. Homeowners need to be aware, historically electric service has never been off for more than one day.
