Slimline Rainwater Tanks

Slimline Water Tanks are available in flat, upright or horizontal designs, these plastic slimline tanks have specifically been designed using opaque polyethene allowing you to see the water level at a glance.

Designed for space restrictive locations

Designed for space restrictive locations these water plastic storage tanks are rotationally moulded for uses throughout the agricultural, commercial, domestic, horticultural, industrial and irrigation markets.

These tanks are perfect for slimline rainwater tanks, water storage for gardens and irrigation systems, loft header tanks, storage of drinking or potable water (WRAS approved) and storage of liquids where space is at a premium.

Many of our smaller slimline water tanks are baffled to add strength and reduce water movement. The storage tanks have a wide range of uses including:

  • Chemical dosing tank
  • Car valeting tank
  • Window cleaning tank
  • Drinking / potable water tank
  • Trailer tank
  • Water bowser
  • Food grade tank
  • Camper/motorhome tank
  • Slimline rainwater tank
  • Rainwater harvesting including under decking

Under Decking Water Tanks

These tanks are used for collecting rainwater from your roof and divert it under your decking and from here use for garden watering or pump it to wash the car and pressure washing.

BSP Tank Outlets

Our slimline tank are fitted with a BSP threaded outlet to allow easy connection of fittings and pipework, additional plastic BSP sockets can be fusion welded into the tanks. Standard tanks are made from semi-translucent polymer but a wide range of colours are also available to order. Lids can be either vented or unvented for potable water applications.

Customised tanks

Outlets are sometimes required in different positions than the standard position and fusion-welded sockets can be added and allowing greater flexibility for the position of inlets and outlets to suit your installation.

Please contact us or download our technical data sheet if you require additional fittings and mark the position of the fittings you require.  Please email this to us to place your order.  All customised tanks are non-returnable.

Colour Options

Tanks in colour options other than black, such as blue, natural, and dark green, are considered as bespoke items and are non-refundable.  Similarly, non-standard outlets are also non-refundable.
