Harlequin Septic Tanks 2700ltr to 6000ltr


  excl. VAT
  • A septic tank is designed to provide what is known as primary treatment to crude waste water produced in a normal domestic environment.

    It retains solids and allows them to settle out, where they can be partially broken down by biological action so that only the remaining liquor is left to flow down the outlet drain. This liquor (normally called effluent) is then sufficiently treated to soak into the ground in an underground soakaway system.

    Impact resistant body moulded in one-piece polyethylene
