Product Description

1000 Litre GRP Sectional Water Tank, Internally Flanged Base (IFB) Divided

1000 Litre GRP Sectional Water Tank, a sectional tank with an internally flanged base and externally flanged sides. Modular construction utilising bolt together panels suitable for on-site assembly.


Tanks with an internal division, which is also known as a maintenance division, are suitable for buildings that we require an uninterrupted water supply during periods of maintenance to the tank. The internal divider creates two isolated compartments within a single tank, which enables one side of the tank to be taken out of service for maintenance, whilst water supply is maintained to the building via the second compartment of the tank.

Please note: divided tanks are essentially two separate tanks & therefore require double the quantity of connections, i.e. 2 x inlet connections & 2 x outlet connections to the down services.

These sectional tanks are insulated and WRAS approved for use with potable water. The water tanks are suitable for a variety of applications including process cooling, rainwater harvesting and many other systems and processes where containment of water is necessary. All gaskets, seals and fixings for assembly are included. Available for self-assembly, or on site assembly is available by qualified engineers for an additional cost.

IFB tanks are suitable for positioning onto a flat, level and continuous foundation, normally a structural concrete slab. 

IFB tanks require a minimum of 500 mm working clearance all around the tank, a minimum of 500 mm above the man-way height and/or 350 mm above any raised float valve housing. 


  • Screened lid vent
  • Screened overflow ¾'' (22 mm) up to 4" 
  • Screened warning pipe ¾'' (22 mm)
  • BSP female tank connector 1" up to 4"

Important: All water storage tanks supplying water to a potable system require pre-commission cleaning and sterilisation.

Applications where there is sufficient working room all around the tank.
