Lake, Wells or Septic: Start With Your System

Innisfil homes are served in more than one way. InnServices supplies about 26,600 people with water drawn from Lake Simcoe and treated at the Lakeshore Water Filtration Plant, and runs municipal wells in Churchill, Stroud and Innisfil Heights. Other properties draw from private wells. Before we plan a bathroom here, we find out which of those the house is on.

Drainage matters even more. Where a home is on a septic system, the Town says adding any plumbing fixtures, any bedrooms or a 15% increase in finished space requires a septic analysis. Properties within 100 metres of the Lake Simcoe shoreline, a municipal well or a watercourse in the Lake Simcoe watershed are also part of a mandatory re-inspection program, inspected once every five years at $142. A new basement bathroom on septic starts with that analysis, not with tile samples.

Innisfil's housing leans new. In the 2021 census, 31.3% of its homes were built in 2011 or later, and 74.7% of all dwellings are single-detached. Those newer houses tend to need ensuite upgrades and finished basements, while older homes along the shoreline, where the Town's history notes a wave of cottage development, often need fuller rebuilds.
