Onsite Sewage Systems

Onsite Sewage Systems

We review, approve, and inspect the installation of onsite sewage disposal systems to ensure effective wastewater treatment to safeguard water quality.

  • Homes not served by public sewer and water systems rely on onsite sewage systems (OSS), typically consisting of a septic tank and drain field, to treat and dispose of wastewater. When designed, installed, and maintained properly, these systems can provide years of reliable service comparable to that of public sewer systems. However, when they fail or are not properly maintained, the consequences can be severe, including property damage, groundwater contamination, surface water pollution, and disease outbreaks.

 

  • To mitigate the risks posed by failed systems to the entire community, all new OSS installations require an application and permit. This process ensures that the conditions for traditional systems are met, that design and installation are conducted professionally, and that the system is set up for long-term safe waste management for both the homeowner and the community. Regardless of the system type, septic tanks should be inspected annually

All new onsite sewage system (OSS) installations require a permit to ensure community safety. While the permitting process can be lengthy due to necessary inspections, understanding the steps involved, using an approved installer, and considering seasonal factors can help expedite the process.

  • The application, along with the associated fee, is reviewed by the Environmental Health department.
  • Test holes are excavated and inspected; an evaluation letter is then issued.
  • The applicant submits the design to the Environment Health Department for review.
  • Environmental Health Department reviews the design; if it meets the criteria and all fees are paid, the permit is issued.
  • Upon receipt of the permit, construction may commence.
  • Once construction is complete, the Environmental Health Department conducts a final inspection and prepares an “as-built” document, which is retained on file with a copy provided to the owner.
  • Currently, it is recommended that a property inspection of the septic system be conducted to ensure that the septic system is still properly functioning.  However, in 2027, property transfer inspections will be REQUIRED.  The property transfer inspection must be conducted by an approved operation and maintenance company and the inspection should be submitted to the health department for review.
