About Us

I’m Chris Gelderman, owner and manager of Helensville Drainage. For the last 12 years, we’ve been sorting out drainage and septic tanks around the Auckland area.

Our certified drainlaying team have over 30 years joint experience in the trade, so we’ve seen it all before. From unblocking drains, to cleaning them and making sure your stormwater or wastewater goes where it should, we know the best solution.


There are a lot of cowboys out there who often won’t provide a service that meets the council’s, or your requirements. Our team on the other hand, are certified drainlayers, so that you can rest easy knowing that every job will be up to scratch.

We provide all of your drainage and septic tank systems

Whether it’s installing drainage, a new septic tank or repairing what is already there, we know how to get the job done and we provide the service that suits you.

We stand behind our work.

If you ever have any problems with our drainlaying service we’ll be back to fix it. All of our drainage products come with a guarantee, which in some cases is up to 15 years!
