Property Information

The Mississippi Rideau Septic System Office (MRSSO) delivers septic system approvals in Tay Valley Township on behalf of the Mississippi Valley and Rideau Valley Conservation Authorities. The MRSSO is responsible for sewage system application evaluation and processing, site visits, permit issuance, follow-up, records management and reporting and public relations.

The Township also operates a Sewage System Re-Inspection Program. The program oversees the annual selection of approximately 100 properties for a non-intrusive, visual inspection. A report of any findings is prepared for the property owner along with reference material on proper system maintenance.

Any homeowner planning renovations should consult with the septic office to determine if there will be an increase in the household design flow. All septic system repairs and alterations require a permit through the MRSSO. Illegal alterations and repairs can cause a serious public health risk. If suspected, these occurrences should be reported anonymously to the MRSSO.
