When Do You Need Well Decommissioning?
Proper well decommissioning is legally required in Ontario when a well is no longer in use. It protects groundwater quality and prevents safety hazards on your property.
🏚️ Abandoned Wells
Unused wells pose serious safety risks and must be properly sealed. In Simcoe County’s rural townships, many older properties in Clearview, Tiny, and Springwater have forgotten wells that need decommissioning.
💧 Converting to Municipal Water
When connecting to municipal water services, your existing well must be professionally decommissioned to comply with Ontario regulations and prevent groundwater contamination.
🔄 Well Replacement
Installing a new well? The old well must be properly abandoned according to Ministry of Environment standards before drilling a replacement.
⚠️ Contaminated Wells
Wells that have been compromised by surface water intrusion, agricultural runoff, or bacterial contamination must be permanently sealed to protect the local aquifer.
🏡 Real Estate Transactions
Selling rural property in Simcoe County? Undeclared or improperly abandoned wells can delay closings and create liability issues for both buyers and sellers.
🚜 Property Development
Construction projects require all existing wells to be located and decommissioned to prevent accidents and ensure compliance with building permits.
Ontario Well Decommissioning Regulations
Well decommissioning in Ontario is regulated by Ontario Regulation 903 under the Ontario Water Resources Act. Compliance is mandatory and protects our shared groundwater resources.
⚖️ Legal Requirement: Ontario Regulation 903
Under Ontario law, any well that is no longer in use must be decommissioned by a licensed well contractor within two years of abandonment. Property owners are legally responsible for ensuring proper decommissioning.

Our Professional Decommissioning Process
Mighton’s Well Services follows strict Ministry of Environment protocols for every well decommissioning project. Our 50+ years of experience ensures safe, compliant, and thorough work.
Site Assessment & Well Location
We begin with a thorough site visit to locate the well, assess its condition, and review available well records. In Simcoe County’s rural areas, we often use probing and electronic detection methods to locate forgotten wells. We’ll document the well’s diameter, depth (if known), and proximity to structures, septic systems, and property lines.
Equipment & Pump Removal
All pumps, piping, electrical components, and well hardware are carefully removed from the well. This includes submersible pumps, drop pipes, wiring, and any obstructions in the well casing. Proper equipment removal ensures the well can be fully sealed according to MOE standards.
Well Cleaning & Preparation
The well is thoroughly cleaned to remove sediment, debris, and any contaminants. This step is critical for ensuring proper seal formation. For wells in Simcoe County’s clay and limestone formations, we assess the geological conditions to determine the appropriate sealing materials and methods.
Professional Sealing & Grouting
Wells are sealed using high-quality bentonite chips and cement grout in alternating layers, following Ministry of Environment specifications. The sealing process varies based on well depth and local geology:
- Shallow wells (0-50 feet): Typically sealed with alternating bentonite and cement grout layers
- Deep wells (50+ feet): Require specialized grouting techniques and multiple seal zones
- Bedrock wells: Common in Clearview and surrounding areas, sealed to prevent surface contamination of fractured rock aquifers
- Overburden wells: Found in Tiny and Springwater areas, sealed through clay and sand formations
Casing Removal or Cut-Off
Where possible, steel well casings are completely removed. If removal isn’t feasible due to well construction or site conditions, the casing is cut off at least two feet below ground level and the void is sealed with concrete. This ensures no surface hazards remain and prevents the well from being mistakenly reused.
Surface Restoration
The well site is restored to match the surrounding grade. Topsoil is replaced, and the area is leveled and seeded if necessary. For wells located in landscaped areas, we take care to minimize disruption and restore the site to its original condition.
Documentation & MOE Reporting
Within 30 days of completion, we file the required Well Decommissioning Report with the Ministry of Environment. You receive:
- Copy of the filed MOE report with confirmation number
- Detailed photos of the decommissioning process
- Site diagram showing well location
- Materials used and quantities

⛰️ Local Geological Considerations
Simcoe County’s diverse geology requires specialized decommissioning approaches:
Bedrock Wells (Common in Clearview, Collingwood)
These wells penetrate limestone and dolostone formations of the Niagara Escarpment. Decommissioning requires careful sealing to prevent contamination of fractured bedrock aquifers that supply water to entire neighbourhoods. We use specialized grout mixes that bond effectively with carbonate rock.
Overburden Wells (Tiny, Springwater Areas)
Drilled through glacial till, sand, gravel, and clay deposits left by ancient Lake Algonquin. These wells require bentonite sealing through multiple geological layers to prevent surface contamination from reaching deeper aquifers. The thick clay layers common in this area provide natural protection but must be properly sealed during decommissioning.
Mixed Formation Wells
Many Simcoe County wells pass through both overburden and bedrock. These require the most complex decommissioning procedures, with different sealing materials and techniques applied at various depths. Our experience ensures each geological zone is properly addressed.
Historic Well Types
Simcoe County has many older properties with hand-dug wells, bored wells, and early drilled wells that predate modern construction standards. These present unique decommissioning challenges due to their large diameter, irregular construction, and often unknown depths. We have extensive experience with historic well decommissioning throughout the region.

Common Well Decommissioning Questions
Answers to the questions we hear most often from Simcoe County property owners.
Do I really need to decommission my old well?
Yes. Ontario law requires any well that’s no longer in use to be properly decommissioned within two years. Beyond legal requirements, abandoned wells pose serious safety risks (collapse, falls) and can create pathways for contaminants to reach groundwater. This protects not just your property but your neighbours’ water supply as well.
What if I don’t know where my old well is located?
This is common with older Simcoe County properties. We have specialized equipment and decades of experience locating forgotten wells. We’ll check available well records, conduct site surveys, and use electronic detection methods if needed. Many wells are hidden under additions, decks, or landscaping.
Can I just cap the well instead of decommissioning it?
No. Simply placing a cap on a well does not meet Ministry of Environment standards. Wells must be sealed throughout their depth with proper materials to prevent contamination pathways and meet regulatory requirements. A cap can be removed, accidentally opened, or damaged, leaving the well as a contamination risk.
How long does the decommissioning process take?
Most residential well decommissioning projects take 1-2 days on-site. The timeline depends on well depth, geological conditions, and site accessibility. From initial contact to completion including MOE filing, the entire process typically takes 2-4 weeks. Emergency decommissioning (safety hazards) can be expedited.
Will decommissioning damage my property?
We take great care to minimize site disturbance. Equipment access is planned carefully, and we restore the surface to match surrounding grade. Any lawn damage is repaired with topsoil and seed. Most Simcoe County properties show no lasting signs of decommissioning work within one growing season.
What happens if I sell my property without decommissioning an old well?
Undisclosed or improperly abandoned wells can cause significant problems in real estate transactions. They may delay or prevent closing, reduce property value, create legal liability for both buyer and seller, and result in regulatory penalties. Most buyers’ lawyers will require proof of proper decommissioning or have it completed before closing.
Do you handle all the paperwork and MOE reporting?
Yes, completely. We handle all documentation, photography, and Ministry of Environment reporting as part of our service. You’ll receive copies of everything filed, including the MOE confirmation. We manage the entire regulatory process so you don’t have to navigate government requirements.
Can a well be reused after being decommissioned?
No. Once a well is properly decommissioned, it is permanently sealed and cannot be reused. If you think you might need the well in the future, discuss this during the assessment. However, most wells requiring decommissioning are abandoned because they’re no longer viable (contaminated, low yield, outdated construction, or replaced by municipal water).
