Civil Drainage Services

Getting the Bay Flowing – We are your civil drainage experts.

At Armstrong Plumbing, we know civil plumbing and drainage inside and out. It’s what we’ve been doing for close to a century. Based right here in Tauranga, we’ve got the experience, gear, and know-how to handle large-scale civil projects across the Bay of Plenty.

Whether it’s a new subdivision, infrastructure upgrade, or a big commercial job, we get stuck in and get it done right the first time. No fluff, no nonsense—just solid work that stands the test of time.
