Ewart Park – Singapore


To provide tank facility for collecting and retaining stormwater for re-use.


A pit was excavated large enough to accommodate the calculated number of VersiTank to be installed. The base of the pit was compacted and levelled with a layer of coarse sand and a liner installed forming an impermeable tank within which assembled VersiTank units were positioned. Piping for inlet, outlet and overflow points were installed. Thereafter the installed VersiTank units were enveloped with a permeable geotextile fabric and covered with coarse sand and topped with planting soil. Planting on top makes the stormwater collection tank completely invisible and high compressive strength allows the space on top to be trafficable so that surface garden space is not compromised.
