Major Civil & Commercial Drainage.
Tuffnell Drainage delivers full drainage and in-ground civil packages for high-value commercial, civil and industrial projects. From shopping centres and education builds to infrastructure and subdivisions, our teams are set up for large, complex jobs – with the people, plant and systems to match.

Our core services
Sewer drainage
Installation and upgrade of sewer mains, laterals and connections on major sites – designed and installed to meet council and consultant specifications, with as-built documentation supplied.
Stormwater & surface water
Stormwater networks, manholes, soak pits and surface water control for roads, yards, carparks and hardstands, including integration with attenuation and treatment systems.In-ground civils
Associated in-ground civil works including trenches, pits, culverts and structures that support the overall drainage design, keeping responsibility for the underground package with one well-coordinated team.
How it works
Planning and pricing
We review drawings, constraints and programme with you up front, so the drainage package is realistic, buildable and resourced properly – not a lowball number that bites later.
Delivery on site
Dedicated crews and our own heavy gear turn up ready to work. We coordinate with other trades and adapt when plans change, so drainage is not the trade holding up the job. Clients consistently comment on our professional approach and collaboration on site.
QA, CCTV and handover
Integrated CCTV and jetting through
Tunnelvision support robust QA, with clear reports and documentation for council and client sign-off.
