What it is

A mobile service that drains, scrubs, rinses and disinfects water storage tanks. Typical jobs are home cisterns, cottage tanks, livestock water tanks and farm holding tanks. You bring pumps, a pressure washer and approved disinfectant to the property.

Your first three steps

  1. Call a few rural homeowners, water haulers and farm suppliers in your area to learn what tanks they have and what cleaning costs now
  2. Price out a pressure washer, submersible pump, wet vac, PPE and a trailer or truck setup, and take WHMIS and confined space awareness training
  3. Offer a discounted first clean to a few neighbours and cottage owners, and ask for reviews and referrals
Who pays

Rural homeowners on cisterns or hauled water, cottage owners opening up for the season, farmers and hobby farms, and small campgrounds.

How it makes money

A fixed price per tank, set by size and how dirty it is, with extras for water testing coordination, disinfection and travel. Many customers book a yearly or twice-yearly clean, which gives repeat work.

Skills that help

  • Check provincial drinking water and disinfectant rules, and which products are approved for potable water
  • Winter freezing and road conditions limit work in many regions, so plan for a seasonal business
  • Wastewater disposal: check where you may legally discharge tank water and sediment
