Plumber in King City

King Township mixes old and new: about 16% of its homes were built before 1961, and 42% after 2000, many in King City's newer subdivisions. King City itself ran on septic systems until a 2005 by-law required homes to connect to the new sewer and decommission their tanks. Much of the rest of the township, on the Oak Ridges Moraine, still relies on private wells and septic systems. King City gets Lake Ontario water blended with groundwater (131 mg/L of hardness), while Nobleton and Schomberg are on groundwater at 264 mg/L, which York Region rates as very hard. Septic systems within 100 metres of a stream in the Lake Simcoe watershed need an inspection every five years.
