Stormwater Retention Tank Installation
Smart underground water storage to meet council attenuation requirements.
Manage and Reuse Your Stormwater Effectively
As New Zealand intensifies its housing, the local stormwater network is under increasing pressure. Many new builds and major renovations now require stormwater retention tanks or storm detention tanks by law.
These large underground water retention tanks capture roof and surface runoff, holding it back during peak storm times and either releasing it slowly into the street mains or storing it for non-potable household use. We specialise in the complex excavation, precise bedding, and secure installation of these heavy-duty tanks, ensuring they are correctly plumbed with overflow safeguards.
