Underground HDPE Water Storage Tank
A custom large-diameter HDPE pipe tank designed for stormwater retention, water reserves and high-volume underground storage.
KUSTOMFLO Tank is a custom underground HDPE water storage tank manufactured from large-diameter pipe. Designed for projects requiring a lote of water storage, it can be used as a permanent subsurface water reserve fed by surface runoff or a natural source, or as a temporary stormwater retention system.
With storage capacity up to 8.8 m³ per linear metre, KUSTOMFLO Tank helps engineers, contractors and project owners create high-volume storage in a compact underground footprint while benefiting from the corrosion resistance, chemical resistance and installation advantages of HDPE.
Common Applications
Large Water Retention Solution
- Stormwater retention and detention
KUSTOMFLO Tank can be used as an underground stormwater storage system to temporarily retain runoff and help control discharge toward the sewer network, outlet or downstream infrastructure. Its large-diameter HDPE configuration makes it well suited for projects requiring high storage volume in a compact footprint.
- Agricultural water reserves
KUSTOMFLO Tank can create a durable underground water reserve for agricultural operations that need to store runoff, spring water or water from a natural source. It helps reduce dependence on rainfall patterns and supports more reliable water availability during dry periods.
- Natural resources and remote sites
For remote or hard-to-access sites, KUSTOMFLO Tank offers a lightweight and corrosion-resistant storage solution that can simplify transportation and installation compared with heavier tank materials. It is ideal for projects where durability, ease of handling and long-term performance are essential.
- Industrial and municipal water storage
KUSTOMFLO Tank can support industrial and municipal projects that require high-volume underground water storage for operational needs, site drainage, emergency reserves or infrastructure upgrades. Its HDPE construction provides strong resistance to corrosion, chemicals and demanding underground conditions.
