The groundwater Protection Policy was established in 1963 as a result of the recommendations of the Tullstrom Study. These policies were revised in 1973 and have been submitted to Parliament for further revisions. The new policies have not been ratified to date. The policy will no longer consists of Zone 1 to 5 but rather Zone A to Zone E. The policies for each zone will determine what can be built and the waste disposal method required. The Zones are named as follows:
- Owners of existing properties in Zone 1 areas be allowed to rebuild their houses and to install water closets and
- Zone A or Pathogen Exclusion Groundwater Protection Areas
- Zone B or Pathogen Management Groundwater Protection Areas
- Zone C or Chemical Management Groundwater Protection Areas
- Zone D or Recharge Contributing Groundwater Protection Areas
- Zone E or Non-recharge Contributing Groundwater Protection areas
Until the new policy has been ratified the Department will continue to work according to the previous policy which is as follows:
- Owners of existing properties in Zone 1 areas are allowed to rebuild their houses and to install water closets and showers under the following conditions:-
(a) houses should remain as one-family dwellings;
(b) where a water closet is installed waste disposal should be by means of a septic tank and a filter bed of activated carbon and a soak away no deeper than 15 feet;
- There should be no change in the use of existing buildings; and
- There should be no subdivision of land where vacant lots will be created.
The areas of greatest restriction are classified as Zone 1 and normally no new developments are allowed by either the Planning and Development Department or the Environmental Protection Department. However, in cases where buildings already exist on the land, a replacement or improvement will be permitted (provided that the building existed prior to July 1973 or received the approval of the appropriate authority).
