Complete Cost Breakdown: New Residential Well
A new residential well installation in the Deep River area involves multiple components — drilling is only part of the total cost. The table below covers all major line items property owners should budget for when planning a new well in northern Renfrew County.
| Cost Component | Typical Range (CAD) | Basis / Notes |
|---|---|---|
| Drilling — per foot | $30 – $55 / ft | Rotary percussion; hard Shield granite at upper end; Deep River/Chalk River area particularly hard |
| Mobilization / rig setup | $400 – $1,500 | Flat call-out fee; higher for Rolphton, Mackey, Stonecliffe properties — contractors travel from Pembroke |
| Steel casing (6-inch) | $1,200 – $3,500 | Depends on overburden depth; includes grouting per Ontario Regulation 903 |
| Wellhead cap & sanitary seal | $200 – $500 | Vermin-proof; required by Regulation 903 |
| Well development (air surging) | $300 – $800 | Clearing fractures after drilling; often included in drilling fee |
| Well shocking (chlorination) | $150 – $400 | Standard disinfection of new well; often included |
| Submersible pump (½–1 HP) | $600 – $2,000 | Equipment only; depends on HP and depth rating |
| Pump installation labour | $400 – $1,200 | Setting pump, drop pipe, wiring, safety rope |
| Pressure tank (44–86 gal) | $450 – $1,200 | Bladder-type; installed in basement or crawlspace |
| Pressure switch & controls | $200 – $500 | 40/60 PSI standard; includes electrical connections |
| Water supply line to house | $1,500 – $6,000 | Depends on distance; buried below frost depth (4–5 ft in Deep River) |
| Electrical service (pump circuit) | $800 – $2,500 | Dedicated 240V pump circuit; electrician required |
| Well record filing | Included by contractor | Mandatory; contractor files with MECP within 30 days |
Total Installation Cost by Well Depth
The single biggest driver of total well cost is depth. In the hard Canadian Shield granite of northern Renfrew County, depth is not predictable in advance. The following estimates assume standard residential pump and tank sizing and typical access conditions.
| Well Depth | Estimated Total Cost | Typical Areas in Northern Renfrew County |
|---|---|---|
| 80–120 feet | $7,000 – $12,000 | Deep River, Chalk River valley areas; deeper Ottawa River overburden |
| 120–180 feet | $10,000 – $15,000 | Most of Deep River and Petawawa area; typical northern Renfrew County |
| 180–250 feet | $14,000 – $20,000 | Rolphton, Stonecliffe, Mackey — hard granite with deeper drilling needed |
| 250+ feet | $18,000 – $28,000+ | Difficult Shield properties; hard granite outcrops near CNL/AECL area |
Note that these ranges include drilling, casing, pump, pressure tank, and water line to an existing structure. They do not include water treatment systems (iron filter, UV, softener, radon aeration), which may add $1,000–$4,000 depending on water quality.
Remote Access Premium for Rolphton, Mackey, and Stonecliffe
Properties located outside the immediate Deep River and Chalk River corridor — particularly in more remote areas like Rolphton, Mackey, Stonecliffe, and Bissett Creek — typically face higher costs due to driller travel distances. Most drilling contractors serving northern Renfrew County are based in Pembroke or Petawawa, and the distance to these remote properties adds time and fuel costs.
Mobilization fees for these remote properties range from $1,000 to $1,500, compared to $400–$800 for properties within the Deep River or Chalk River townsite. In some cases, contractors may also charge a per-kilometre travel fee for equipment transport. Property owners in these areas should expect to receive quotes that include a remote access premium.
Factors That Push Costs Higher
Hard Rock Drilling
The Deep River and Chalk River area sits on some of the hardest granite in the Grenville Province. The CNL and AECL vicinity has particularly dense, unfractured rock. Drilling speed in these zones can be significantly slower than in other parts of Renfrew County, increasing per-foot drilling costs. Some contractors charge at the higher end of the $30–$55/ft range for the most difficult granite.
Extended Depth Requirements
If adequate yield is not found at an expected depth, the driller continues deeper. Each additional 50 feet adds $1,500–$2,750 in drilling cost. Property owners should be aware that the driller cannot guarantee water at any specific depth, though finding adequate yield is the typical outcome.
Long Water Lines
Deep River area properties with substantial lot sizes may require long supply lines from well to house. Every 100 feet of buried supply line adds approximately $600–$1,500 in excavation and pipe cost, depending on terrain. Frost depth in the Deep River area is 4–5 feet, so trenching costs are significant.
Budget Contingency Recommendation
Experienced northern Renfrew County property owners commonly recommend budgeting 15–25% above the initial estimate. Depth is the primary unknown — hard granite means slower drilling and higher per-foot costs. A project budgeted at $12,000 could reach $15,000–$16,000 if the well requires an extra 100 feet to reach adequate fractures.
Well System Component Replacement Costs
Existing well owners in the Deep River area also face periodic repair and replacement costs. The following table covers common replacement items.
| Repair / Replacement | Typical Range (CAD) | Notes |
|---|---|---|
| Submersible pump replacement | $1,200 – $3,500 | Includes pulling old pump, new pump, reinstall; depth-dependent |
| Pressure tank replacement | $600 – $1,500 | Installed; tank plus labour |
| Pressure switch replacement | $200 – $500 | Often done with pressure tank service |
| Well cap replacement | $150 – $350 | Vermin-proof sanitary cap |
| Well casing extension | $400 – $1,200 | If casing has settled below grade |
| Hydrofracturing | $1,000 – $3,000 | Low-yield stimulation for hard granite; results vary |
| Annual water test (bacteriological) | $25 – $80 | Government lab or private accredited lab |
| Full chemical water test | $150 – $450 | Private accredited lab; comprehensive panel |
