What it is

Emptying septic tanks, cesspits and small treatment plants with a vacuum tanker, then taking the waste to an approved disposal point. Many customers need this once a year or so, which can build into a repeat round.

Your first three steps

  1. Price up a new or used tanker and check what driving licence category you need for its weight
  2. Ask the Environment Agency (or the equivalent body where you live) about waste carrier registration, and find out where you can legally discharge waste
  3. Map the rural villages within 30 minutes of home and introduce yourself to parish councils, letting agents and farms
Who pays

Rural homeowners, farms, holiday lets, pubs, campsites and small rural businesses without mains drainage.

How it makes money

Fixed price per empty based on tank size and distance, plus extra for emergency call-outs, blocked tanks and optional inspections. Annual reminders keep customers coming back.
