A garden suite on a well and septic in Essa
Can I add a garden suite on a septic system in Essa?
Yes, if your septic system can carry the house and the suite together. A garden suite with a kitchen and bathroom adds a new source of sewage, so a qualified septic designer checks the combined load before you order. If the system has room, the suite can connect to it; if not, it may need to be altered, expanded or replaced.
Who approves septic systems in Essa?
The Township of Essa Building Department approves septic systems itself, so the septic review and the building permit both go through the municipality.
