What it is

Cleaning and disinfecting larger tanks on farms and rural sites, such as livestock water tanks, troughs, rainwater tanks and private supply storage, using a van-mounted kit.

Your first three steps

  1. Take a water hygiene or tank cleaning course and learn about private water supplies in your area
  2. Source a van and kit: pressure washer, transfer pump, wet vacuum, hoses, PPE and a water carrier
  3. Visit local farms, estates and holiday let owners, and ask to clean one tank at a discount for a reference
Who pays

Farmers, smallholders, rural estates, holiday lets, campsites and homes on private water supplies.

How it makes money

Priced per tank, by size and access, often with seasonal or annual repeat visits. Travel between sites is a cost to build into prices.
