“Highly Recommended”

Ben Giesen

We had to find a company to design and install new septic tanks and sand trench effluent fields for several new houses we were building. The new systems are now in place as per our request and Peter Hansen Drainage did a good job. We found they deliver projects on time, offer a professional service that is easy to use, and work in well with other contractors. Highly recommended.

  • Get the right expertise. We can handle your council requirements, design, approval – right thru to excavation, installation, servicing, & septic tank repairs.
How to identify what type of septic tank you need:
  • Looking for the most cost-effective, environmentally friendly, tried & tested, low maintenance system? Whether it’s sand trench, soak pit or effluent field installation or a We can help.
  • First we’ll consider your soil type, water height level, nitrate levels, & a few other factors.
  • Then we’ll discuss which options will work best for you. Explain how each affects your property & ongoing costs.
  • From standard systems (sand trench effluent discharge) to wastewater treatment options to water your gardens (aerated system with a dripline effect).
  • Over 18 years experience with septic systems, tank draining, installation and repairs. Local knowledge from helping 500+ lifestyle block owners all over Canterbury. Peter will guide you through the process. So you end up with a great system – & the right solution for your site & situation.

    Price differences between systems can vary. Sometimes a flash-whiz-bang system is appropriate.

    Don’t be caught out paying more than you need to!
Already got your septic tank design sorted? No worries. We can install any system.
