💧 Well Drilling

Well Repair & Rehabilitation — Before You Drill a New One

A declining well is not always a dead well. Screen incrustation, biofouling, and pump wear are often treatable — at a fraction of the cost of drilling new.

What's Covered

  • ✓ Screen incrustation: mineral deposits reduce flow into the well
  • ✓ Biofouling: iron bacteria form biofilm — chemical treatment helps
  • ✓ Pump wear often mimics declining yield — test pump first
  • ✓ Rehabilitation: brushing, acid or chlorine treatment, development pumping
  • ✓ Hydrofracturing for hard rock wells: 60–75% success rate

Typical Costs in Spokane

Well inspection + yield test$300 – $600
Rehabilitation (chemical + development)$1,000 – $3,000
Hydrofracturing (hard rock wells)$2,000 – $5,000
New well (when rehab fails)$11,000 – $21,000+

Common Questions

My well seems to have less water — what is happening?
Several causes: screen incrustation, pump wear (often mistaken for yield decline), biofouling, or aquifer changes. A yield test and inspection diagnoses the actual cause before spending money on treatment.
How do I know if I have iron bacteria?
A reddish-brown gelatinous slime in toilet tanks or on plumbing fixtures. Metallic taste or smell. A water test specific to iron bacteria confirms it. Treatment: high-dose chlorination followed by development pumping.
When should I just drill a new well?
When the casing has structural damage, when rehabilitation has failed, or when rehab cost approaches new well cost. A licensed driller with regional experience will give you an honest assessment.
