Product Description

Etills 400 Litre V1 Underground Non-Potable Water Tank

The Etills 400 Litre V1 Underground Water Tank is one of the slimmest tanks in the range, at just 345mm wide. It drops into a narrow trench, so it works well along a fence line, a driveway edge or a tight side passage.

Fill it from your roof and use the water for the garden, the car or the patio.

Specification

  • 400 litre capacity
  • 1240mm long x 345mm wide x 1500mm high
  • 12″ access lid
  • 4″ inlet and outlet connections
  • Medium density Polyethylene, seamless one piece moulding
  • Weight 35kg

Slim Design

Because it is tall and thin, this tank keeps the dig width to a minimum. On the other hand, the hole needs to be around 1.5m deep. If depth is a problem, look at the lower 400 litre V2 instead.

Getting It in the Ground

Start by digging a trench a little wider and longer than the tank. Then lay a level base and lower the tank in. Once the 4″ pipework is connected, backfill evenly in stages.
