For a new septic system or septic system holding tank regulated under the Ontario Building Code Act, 1992, with the exception of a new septic system or septic system holding tank that is required for a municipal water supply well facility, the County shall amend their Official Plan and the Area Municipalities shall amend their respective Zoning By-laws to prohibit uses, buildings or structures requiring a new septic system or septic system holding tank in areas where such activities would be significant drinking water threats, to ensure they never become significant drinking water threats. For the purposes of this policy, upgrading, alteration, expansion or replacement of an existing septic system or septic system holding tank to an improved standard shall not be considered to be a new system
