    FAQS

    Questions, Answered

    What is an OSD tank?

    An on-site detention tank holds stormwater during heavy rain and releases it slowly, so the public system isn't overwhelmed and your property drains safely.

    Do I need an OSD system?

    Many Sydney councils require one for new builds or extensions that add hard surfaces like roofs, paving or driveways. We check what your council requires.

    How much does OSD installation cost in Sydney?

    It depends on the tank size, your site and the design. We don't quote blind. After a site visit you get a clear price.

    Do you handle council approval and certification?

    Yes. We provide flow testing and all the documentation your council needs to sign off the system.

    What areas do you cover for stormwater and OSD?

    Ryde, North Ryde, Carlingford, Castle Hill, Baulkham Hills, Parramatta and surrounding areas. Ask us if you're nearby.

    How long does an OSD installation take?

    It comes down to the system size and site. We give you a realistic timeline after the assessment.

      Book Your On-Site Assessment

      With heavier rainfall and stricter council rules, a dependable stormwater system is worth getting right. We offer complete solutions, including correctly sized OSD tanks that detain and release water gradually, drainage systems that divert flow away from structures, and erosion control to protect your landscape. Every installation meets Sydney council standards, so your property stays safe, functional and ready for whatever the weather brings.
