On-Site Detention (OSD) tank systems and dual-purpose water reserves are critical for managing heavy rainfall and protecting properties across New South Wales. Because these systems are frequently buried, enclosed, or structurally isolated, heavy silt accumulation, liner degradation, and structural faults routinely go unnoticed for years.
At NSW Water Tanks, we provide specialised maintenance, robotic inspections, and certified compliance audits across both commercial assets and rural properties. Utilising non-invasive ROV (Remotely Operated Vehicle) technology, we help you satisfy strict local council regulations and fire safety mandates—without draining your water or halting your operations.
Stormwater tanks face vastly different operational demands depending on their environment—from handling heavy commercial carpark runoff to securing vital static water supplies for bushfire defence. Because we utilise versatile, advanced robotic technology, our team delivers targeted, high-tier inspection and maintenance solutions tailored precisely to the distinct regulatory and structural pressures of your property class.
Traditional tank audits require draining the asset, wasting thousands of litres of vital water. Our submersible ROVs inspect your infrastructure while it remains fully online.
Traditional inspections rely on technicians entering hazardous, tightly enclosed spaces. Our surface-controlled robotic drone technology removes this liability.
Equipped with 4K UHD cameras and powerful 6000-lumen LED arrays, our inspection systems clearly identify lining tears, floor pitting, wall panel deflection, and structural stress hidden beneath the waterline.
Our experienced technicians assess your OSD tank access point and completely disinfect our submersible ROV units. This strict sanitisation protocol ensures zero biosecurity or chemical contamination enters your asset.
The robotic drone is lowered into the active, full detention tank. Our trained pilot maneuvers the craft throughout the interior, bypassing the need for hazardous human confined-space entry.
We visually map the tank’s internal structural integrity via the ROV, while surface technicians inspect your discharge pathways, valves, and flow-control hardware.
You receive a comprehensive, data-driven condition report complete with recorded 4K footage logs, structural integrity ratings, and priority advice for any required water tank repairs or silt extraction to satisfy council and insurance rules.
An On-Site Stormwater Detention (OSD) tank is a specialised water storage system engineered to capture heavy stormwater surges on properties with large impervious surfaces (like roofs and carparks). Rather than letting water rush instantly into public storm drains, it holds the volume temporarily and releases it at a controlled, slower pace to prevent downstream flash flooding.
No. Thanks to advanced underwater ROV technology, we conduct visual structural audits, weld stress checks, and internal component clearances while the unit remains fully operational and full of water.
For commercial and industrial assets where the water is a dedicated fire reserve, the system must meet the routine monthly, annual, and 5-yearly servicing cycles outlined under Australian Standard AS 1851-2012. For rural homesteads, regular seasonal audits ensure your Static Water Supply (SWS) works when you need it most.
Yes, dramatically. While rainwater tank maintenance focuses on filtering fine organic sediment for domestic drinking water, stormwater detention assets capture raw surface runoff. This results in significantly higher volumes of mud, heavy sand, and debris, requiring industrial clearance and specialised inspection diagnostics.
If our ROV maps a compromised internal lining, panel corrosion, or faulty discharge plumbing, we provide a prioritised, costed repair roadmap. We specialise in structural remediation, including high-durability tank relines and advanced internal membrane replacements, to extend your asset’s lifespan.
Don’t wait for the next heavy rainstorm or regulatory audit to uncover a vulnerability in your water infrastructure. Partner with the experts at NSW Water Tanks to secure your assets, avoid costly structural failures, and clear your compliance obligations cleanly.
Pioneer, has been designing and manufacturing rural water tanks for over 30 years, and we’re so confident in their durability that all tanks come with an exclusive Pioneer 20/20 warranty.
That means a 20-year conditional structural warranty, in addition to a 20-year conditional warranty gainst water leakage (only applicable for tank models GT10—GT280.)
With NSW Water Tanks as part of Pioneer’s Dealer Direct® Network, you’ll benefit from the expertise and personalised service of a local family business with nationwide support.
