Water and Well Tests
Essential for rural properties
Rural Properties - Essential Verifications
When purchasing a property not connected to municipal water and sewer systems, thorough verification of water quality and septic systems is crucial. Financial institutions typically require confirmation of water potability and system compliance before approving mortgage financing.
These verifications are an integral part of the real estate broker's duty of verification and advice, as they are pertinent factors to the transaction.
Water Testing - What You Need to Know
What is a water test?
A water test analyzes samples from your well or water source to determine if the water is safe for consumption and meets health standards.
Parameters analyzed
Microbiological analysis:
- Total coliforms
- E. coli bacteria
- Other harmful bacteria
Physicochemical analysis (if recommended):
- Minerals: calcium, magnesium, iron, manganese
- Heavy metals: lead, arsenic, mercury
- Chemical contaminants: nitrates, fluoride, chlorine
- pH levels and water hardness
When to test
- Before purchasing a property with a well
- Annually for maintenance
- After repairs to the well or plumbing system
- If you notice changes in taste, odor, or color
Costs and timelines
- Microbiological test: $50-150
- Complete physicochemical test: $200-500
- Results: 5-10 business days
Required Documents by Water Supply Type (OACIQ)
Public network (municipality)
- Property tax bill
Private network
- Copy of contract or agreement with network owner
- Network number
- Invoice for subscription or maintenance
- All documents reporting declared or resolved issues
Well or source (single property)
Installed before 2003:
- Copy of installation invoice
- All documents reporting declared or resolved issues
Installed after 2003:
- Copy of drilling report
- Water test results from installation
- All documents reporting declared or resolved issues
Installed after 2015:
- All documents required after 2003
- Copy of hydrogeological report (required since 2015 if minimum distances are not respected)
Well or source (multiple properties)
In addition to the above documents, provide a copy of the water drawing easement.
Unknown system
If the seller has no documents and diligent verifications cannot demonstrate the nature of the water supply, a mention must be made on the property listing: "unknown system".
The collaborating broker must warn the buyer of the inherent risks and recommend consulting a qualified person such as a well driller.
Septic Systems and Drain Fields
How Septic Systems Work
A septic system treats wastewater from your home when you're not connected to municipal sewers. It consists of:
- Septic tank: Receives wastewater, separates solids from liquids
- Drain field: Filters and treats liquid waste through soil
- Distribution pipes: Distribute treated water to the drain field
Required Maintenance
- Septic tank pumping every 2-4 years
- Regular inspection of the system
- Avoiding harmful products that kill bacteria
- Water conservation to avoid overloading
Types of Septic Systems
1. Conventional Septic Tank
Most common system. Wastewater flows into a septic tank where solids settle. Liquid flows to the drain field.
Advantages: Simple, reliable, low cost
Disadvantages: Requires sufficient space and suitable soil
2. Sand Filter System
Uses a sand filter to treat wastewater before distribution to the drain field.
Advantages: Works in poor soil
Disadvantages: Higher cost, more maintenance
3. Aerobic System
Adds oxygen to accelerate bacterial decomposition of waste.
Advantages: More efficient treatment
Disadvantages: Higher cost, requires electricity
4. Classic Drain Field
Network of perforated pipes buried in gravel trenches.
5. Filter Bed Drain Field
Uses layers of sand and gravel for filtration.
6. Mound System
Built above ground when soil is unsuitable or water table is high.
Lifespan and Replacement
Typical Lifespan
- Septic tank: 20-40 years (concrete or fiberglass)
- Drain field: 15-25 years depending on maintenance and soil conditions
Signs Replacement is Needed
- Persistent sewage odors around the property
- Slow drains throughout the house
- Sewage backup in the house
- Soggy ground or standing water above the drain field
- Lush, abnormally green grass above the drain field
- High nitrate or bacteria levels in well water
Replacement Costs
- Complete septic system: $15,000-$30,000+
- Drain field only: $5,000-$15,000
- Costs vary by system type, soil conditions, and property access
Problem Detection
Warning Signs
- Sewage odors inside or outside the house
- Slow drains or gurgling sounds
- Sewage backup in toilets or drains
- Wet, soggy areas above the drain field
- Unusually green or lush grass above the system
- High water levels in the septic tank
- Contamination of well water
- Frequent need for pumping
Professional Inspection
A specialized septic inspection includes:
- Locating and uncovering the septic tank and distribution box
- Checking tank condition and water levels
- Inspecting baffles and filters
- Evaluating drain field condition
- Testing soil absorption
- Reviewing maintenance records
Cost: $300-$600 for a complete inspection
Prevention
- Regular pumping every 2-4 years
- Water conservation
- Avoid flushing harmful products
- Protect the drain field (no vehicles, no deep-rooted plants)
- Annual visual inspection
Required Documents for Septic Systems (OACIQ)
Systems installed before June 15, 1981
- Copy of installation invoice
- Copy of building or renovation permit
Systems installed since June 15, 1981
- Copy of municipal permit and professional plan
- Copy of maintenance contract for certain systems
For all cases
- Letter from the city attesting or not to the issuance of a notice of non-compliance
- Recommend the seller waive guarantee on septic installations
- All documents reporting declared or resolved issues
- Recommend the seller have the septic tank pumped or obtain invoice of last pumping
Unknown system
If the seller has no documents, the broker must mention it on the property listing.
Complete and have clients sign the 'Seller's Declarations on the Property' form.
The collaborating broker must warn the buyer of the inherent risks and recommend consulting a competent person such as a specialized contractor.
Note on wastewater system
In all cases, the broker's recommendation to the seller should state in the brokerage contract, reproduced on the property listing, that the seller cannot guarantee the compliance of their septic installations.
