Minimum Distance Requirements
Provincial regulations outline minimum distance requirements as follows. Equivalent
imperial distances in feet are rounded up to nearest foot. The well must be:
10
m (33 ft.) from a watertight septic tank
15
m (50 ft.) from a sub-surface weeping tile effluent disposal field or evaporation
mound or an outdoor pit privy
30
m (98 ft.) from a leaching cesspool*
50
m (165 ft.) from sewage effluent discharge to the ground surface
100
m (329 ft.) from a sewage lagoon
30
m (98 ft.) from pesticide or fertilizer storage
50
m (165 ft.) from above-ground fuel storage tanks
30
m (98 ft.) from manure or composting materials application
100
m (329 ft.) from a manure storage facility or manure collection area or
livestock yard
100
m (329 ft.) from dead animal burial or composting site
2
m (7 ft.) from overhead power lines if:
-
the line conductors are insulated or weatherproofed and the line is 750 volts or less
6
m (20 ft.) from overhead power lines if the well:
-
has a PVC or non-conducting pipe pumping system
-
has well casing sections no greater than 7 m (23 ft.) in length
12
m (40 ft.) from overhead power lines for all other well constructions
3.25
m (11 ft.) from existing buildings
6.1
m (20 ft.) from the outer boundary of any road or public highway
50
m (165 ft.) from the outer boundary of a graveyard
450
m (1476 ft.) from any area where waste is or may be disposed of at a landfill
*
The installation of a leaching cesspool
is no longer permitted. It is, however,
highly recommended that any newly
constructed water well be located at least
30
m (100 ft.) from any existing leaching
cesspool. See Module 12 "Other Resources"
for the requirements for Alberta Private
Sewage Systems.
