Flo-Vault®
The Flo-Vault® is a structural lightweight modular tank system used to construct underground water storage for various applications. The modular nature of the system allows for the easy construction of tanks of any volume and can be designed to accommodate specific site conditions.
Coerco modular tank systems use surface and underground infiltration techniques, resulting in clean water that can be re-used or allowed to re-enter the natural water system. Coerco modular tank systems offer a highly efficient option for storm water management in any kind of soil.
Water Quality
Coerco modular tank systems excel when there is a requirement to achieve high water quality, particularly in the effective removal of nutrients and gross pollutants. In addition to the obvious environmental benefits, the sub -surface location of the tank system provides more useable ground area and enhanced aesthetic setting compared to above ground concrete or plastic tanks.
The Modular Advantage
Coerco modular tank system performance supersedes outdated aggregate trenches. The Coerco system provides a void space of over 90% compared to less than 20% in typical aggregate trenches. Consequently, with a smaller footprint the Coerco system achieves the same storage capacity as an aggregate trench. This saves time and money in installation and civil works costs. The lightweight design of Coerco modular tank modules also make installation quicker, safer and cheaper. No sediment build up occurs in the Coerco system, unlike the clogging that is characteristic of aggregate based approaches.

" We approached our plumbing supplier in Bunbury ,Macro Irrigation, looking for a tank to replace the existing one that had a split in the base of it, we had already had quotes but when we asked for 2 brass 80mm outlets in the tank we were told it could be done but cost a lot more and macro organized our tank from Coerco and the fitting were no issue done at the manufactures and the tank was delivered just as we ordered, the driver was helpful and friendly and also gave us some tips on ensuring the ground in our yard wasn’t going to damage the new tank. Will be looking at another purchase in the future and also recommend them as a supplier to our purchasing officers. "
