Underground Water Tanks
The new of horizontal SUB under water ground tanks are the ultimate in underground water management.
The SUB’s are light enough to be manhandled which is a major benefit when section access is limited and once installed the only part visible is a low profile childproof manhole cover. With 7 different length combinations and capacities ranging from 2,000 litres to 5,000 litres, the SUB’s suit almost all applications. But should more volume be required, it is a straightforward procedure to link multiple tanks together.
New development often places additional demands on stormwater systems, these systems may not have the capacity to handle further loads. Often in these situations a stormwater detention tank is the best solution. Stormwater detention tanks are designed to store rainwater from roofs, drives, paths and other impervious areas. The water is then discharged to the stormwater system from the tank through a small diameter orifice pipe at a rate the stormwater system can cope with.
The SUB’s are perfect for stormwater detention and make light work of council requirements. Each tank comes with preset connection points for inlets, outlets and overflows. It is a simple procedure to fit the specified orifice.
- Ribbed design for strength.
- Ultimate solution for stormwater retention.
- Multiple inlet and outlet positions.
- Wide foot for easy leveling.
- 300mm deep sump.
- Integrated lifting points.

Yes Bailey SUB tanks have been engineered to handle the external loads from the back filled material and also hydrostatic uplift.
Yes Bailey SUB tanks have been designed to meet council requirements. We can also supply a producer statement (PS1)for the design to submit to council with your building consent application.
No. The controlled orifice must be kept open at all times to allow the tank to slowly drain to the stormwater. However you can elect to install a larger tank than required by council and utilize the extra capacity around the house.
Yes. The tank will need to be restrained from moving though.
No. A qualified plumber or drainlayer is required to install Bailey SUB tanks. Often a PS3 will be required from the installer for council.
The SUB5000 tank is our recommendation as it is best suited to this application and is a cost effective solution.
