What it is

A specialist service for larger tanks: building water storage, process and fire-suppression tanks, and large farm or processing facilities. It uses bigger equipment, trained crews and written procedures, and often includes inspection photos and reports.

Your first three steps

  1. Complete confined space entry, fall protection and WHMIS training through a recognized provider in your province
  2. Contact property managers, facility managers and water treatment companies to ask how they currently handle tank cleaning, and offer a trial job
  3. Get quotes for commercial insurance and for a tank-cleaning pump, vacuum and rinse setup, then build a written safety procedure and report template
Who pays

Property managers, industrial and food processing sites, agricultural operations, municipalities and small water utilities.

How it makes money

Per-tank pricing or a yearly maintenance contract, with higher rates for large or hard-to-access tanks and for documentation and reporting.
