Here at Drayton Tank we provide several variations on the same tank capacities and sizes, we have briefly detailed these types below to help you when choosing a tank suitable for your requirements.
Water Tank Types:
One Piece Water Tanks –
The One Piece Tank type is a single moulded Open Top Tank that is supplied with a Bolted Lid, the tank is manufactured from approved materials for its purpose including Potable Drinking Water (WRAS Approved),
The Tank is normally supplied with the bolted lid, the lid should always be bolted down as it provides integral support to the tank walls, the tank can also be supplied open top, which usually requires the tank to be made stronger,
Two Piece Water Tank Types –
The Two Piece Tank Type is moulded in Two Sections, split horizontally half way up the internal height of the tank with a bolted flange for fixing back together once in situ with the supplied bolted and mastic sealer,
The two sections are usually rotated to allow them to pass through the restricted access, The sections can also be specifically designed to fit through a required gap eg doorways, which may require the tank to become a Three piece water Tank.
Sectional Water Tank Types –
Sectional Tanks are Water tanks made up of a number of panel to create a larger tank in a space like a basement where restrictions like doorways and corridors and stairwells prevent a single large tank access.
Sectional tanks themselves come in 3 Different Water Tank Types
IFB – Internally Flanged Base – this is the most common type of sectional tank and is externally flanged sized and lid, with the tank base being internally flanged so the external of the tank base is flat and suitable to be placed onto a flat smooth concrete floor, pad or other flat surface – These tanks require 500mm Around each side to allow assembly.
EFB – Externally Flange Base – These sectional are externally flanges on the sides, lid and base, and are designed to sit on Pillars, walls or Steels that are raised off the ground, also classed as fully draining sectional tanks, the supporting Steels or walls should match the joints on the tank panels (usually 1m) so the external flange of the base panels rest centrally on each steel or wall. – These tanks require 500mm Around each side to allow assembly.
TIF – Totally Internal Flanged – TIF Tanks are produced with all flanges internally bolted, this means the tank only needs 50mm around the tank to enable assembly, utilizing the space available, these tanks can be sat on a concrete Floor or plinth.
Twin Compartment Water Tanks –
These tanks are usually one of the above types of tanks, with the added feature of a division plate inside the tank to create two separate compartments, usually the plate is centrally spaced to give two equal compartments, also can be off centre if required by the design,
The tank would usually require 2x the accessories and fittings to provide the access and the fittings to each side, enabling the tank to be drained down and maintained whilst keeping one side in operation.
