TYPES OF WELLS
To effectively maintain your well it is important to understand what type of well you have and general construction principles of your well system.
1. Dug Well
Dug wells are typically shallow (9 meters/30 feet or less) and excavated
by hand or backhoe. The well walls are often lined with rocks, bricks,
wood or concrete to prevent surface water from entering the well or having
the walls cavein.
2. Bored Well
Bored wells are shallow (15 meters/50 feet or less)) and dug with a
boring rig or a power driven earth auger. The bored well is typically lined
with concrete tile or corrugated, galvanized pipe.
3. Driven, Jetted, Sand Point Well
Driven, jetted and sand point wells are approximately 15-18 meters/50-60
feet deep. These types of wells can be constructed by hand or by using
a small drilling machine to drive a point, fitted with sections of pipe
into the ground.
4. Drilled Well
Drilled wells are deep wells -- 15m (50ft) to 60m (200ft or more) --
that are excavated using rotary hydraulic or percussion drilling equipment.
The casing of a drilled well is usually steel. The well head may extend
above the ground or be contained in an access pit.
Dug and bored wells, particularly those that are old, are more prone to contamination than driven, jetted, sand point and drilled wells. Dug and bored wells are shallow therefore, the acquifer can become easily contaminated by surface water or impurities which may percolate down from the ground surface. Furthermore, the ground water bearing soil is usually penetrated only for a short distance and therefore after considerable heavy water usage or during a drought the dug well might run dry.

East of the City of Toronto, Durham Region is an area of endless variety and contrasts. The Regional Municipality of Durham is one of the fastest growing centres in North America. The Region comprises an area of approximately 1,000 square miles, providing ample space for industry, commerce and families to prosper. Durham Region is rapidly becoming the prime location for industry and commerce. It is also an equally popular location for residential expansion, thus evolving an almost perfect blend of location, resources and human attributes. Durham is home to over 495,000 residents.
