Connecting neighborhoods served by a private treatment facility

If your home and your neighbor’s homes are all connected to a common treatment facility such as a neighborhood lagoon, and you and your neighbors are in need of assistance with managing the system, the District may be able to help.

The process for transferring ownership, operations and maintenance to the Sewer District is as follows:

  1. Concept Review – Representatives of the neighborhood meet with District personnel to discuss transfer of ownership of the private system to the Sewer District.
  2. Inspection of private treatment and collection system – District personnel evaluate the system. The District will not accept a system that does not meet its standards.
  3. Review of Inspection Report – The District shares results of inspection with owners.
  4. Completion of Improvements – If needed, owners complete the improvements documented in the inspection report at their own expense. If the costs are substantial there are additional option available. Please contact the district to inquire about SSIA’s
  5. Connection/Inspection Fees (when applicable) – The owners will need to pay any applicable fees.
  6. Transfer of Sewer Easements – All easements to the collection system must be transferred to the Sewer District to allow access for operations and maintenance.
  7. Transfer of Ownership – Once improvements are complete and the project is inspected and accepted, the neighborhood transfers real estate ownership to the Sewer District by way of a Warranty Deed and other property by Bill of Sale.
  8. Transfer of O and M – Sewer District takes over operations and maintenance of the system.
  9. Initiate Monthly Sewer Service Bill – Property owners receive a monthly sewer service bill.


If you are experiencing a problem with your septic system or private lagoon, you may want to look into connecting to a public sanitary sewer system. Occasionally, properties with on-site systems are situated in areas where it is feasible to connect the individual property to public sewer.

  • There are costs associated with connecting to public sewer:
  • The property owner will need to hire an engineer to design the connection.
  • The cost of constructing the lines to connect your property to the public system is the owner’s responsibility.
  • The owner must pay all applicable Sewer District fees.
  • There will be a monthly sewer service bill

However, once his/her property is connected, the homeowner will never have to face the expense of improvements to an on-site treatment system.
