Drainage

Protecting Your Land and Investment

When effective water management matters, do you have a partner who can deliver expertly designed and installed drainage solutions that perform in all conditions?

Water is one of the most significant variables in any civil or agricultural project. At the Rooney Group, we specialise in the high-precision drainage systems required to protect your land, infrastructure, and long-term investment. By combining our extensive plant fleet with technical engineering expertise, we ensure that water is managed efficiently; preventing erosion, protecting foundations, and ensuring your site remains operational regardless of the weather.

Stormwater & Wastewater Reticulation

Managing water in urban and industrial environments requires surgical precision and a deep understanding of regulatory compliance. We provide comprehensive reticulation services, including the installation of large-diameter concrete piping, manholes, and complex filtration systems. Whether we are connecting a new subdivision to municipal mains or developing a high-capacity industrial stormwater network, our “Do it Once, Do it Right” philosophy ensures a leak-proof, durable system that guards against flooding and environmental contamination.

Agricultural Drainage

To maximise the productivity of South Island soils, effective drainage is essential. We work with landholders to design and implement large-scale agricultural drainage schemes, including the creation of open-drain networks and the installation of sub-surface tile drainage. These systems are engineered to manage the water table and improve soil structure, allowing for better pasture growth and stock management. Our team understands the local terrain and soil types, ensuring your drainage solution is perfectly suited to the specific demands of your property.

Culverts & River Works

Protecting critical access points and boundaries requires robust engineering that can withstand the power of the South Island’s waterways. We specialise in the installation of high-capacity culverts, and the execution of complex river-protection works. From managing water flow during construction to the placement of heavy rock armouring for bank stabilisation, we ensure your infrastructure is protected from the risks of washouts and erosion. Our integrated approach manages everything from resource consent requirements to the final mechanical installation, providing a secure, long-term solution for your landscape.
