Because they’re primarily underground, stormwater devices and infrastructure are sometimes neglected but it’s important to maintain stormwater systems. We have a long history of stormwater management and are experts in maintenance and best practice. From site evaluation to project completion, we can help you with your stormwater needs.
HydroVac is the number one maintenance service provider. We maintain numerous types of stormwater structures, ensuring filters are clean, unclogged and free of debris and sediment.

- Cesspits and sumps. We recommend yearly servicing

- Soak holes
- Rain gardens, including plant replacement, site rejuvenation, makeovers for continuous council compliance and routine auditing as required under stormwater management plans
