Case Study

We highly recommend the Tankless System. The Tankless underground water tank system has provided excellent, trouble-free storm water capture for our garden for over 13 years. Our only issue was this year when the pump stopped working. Darren promptly installed a replacement pump and performed a service for the system (the first that it has ever required). Can't speak highly enough about the system and the service provided by Tankless.

Darren converted our pool a year ago and it has been a great success. We had a small problem with the pump recently and he came and repaired it really promptly. Overall, he has provided a great product and service. Andrew and Linda, Warrandyte

We installed a Tankless water tank under our driveway in 2009. The system has been fantastic and never had an issue with great quality water. My advise is to go bigger than what you think you require, it will be worth it.

Darren and his team recently converted our underutilized swimming pool into a 42900 litres underground water storage. It took a week's work and we were very pleased to see the underground water storage system working well. We now have rainwater captured in the underground storage for watering our garden. Darren was very reliable, professional and knowledgeable in what he was doing and delivered what he promised. We also had Darren and his team landscaped the converted pool into a outdoor sitting area with garden pavers and steppers. Overall, we are very pleased with Darren and his team's work and happy with our underground water storage system and reclaimed outdoor space.

Darren installed our tankless system 10 years ago and it's been a great solution for a difficult site and functioned very well. Darren recently serviced the system and was prompt and efficient.

Darren & his team provide prompt & reliable service. Pleasure to work with.

Just over 15 years ago, Darren put in a 30,000 underground water tank to look after our gardens. It's proved to be an excellent investment. Recently, Darren came by to service the system and install a new submersible pump. Excellent service and the tank has certainly served the test of time !

Great product and service. Hard to find experts that know the whole end to end process for building tank and linking it effectively to garden water system and house grey water. Darren was just great.

Just had our Tankless underground tank serviced after 11 years of trouble free use, no issues and great customer communication. would recommend this company. Mike , East Malvern, Vic

Tankless installed a 18,000 litre tank under my frony lawn over 10 years ago. As an engineer, I checked out every aspect of the installation and was happy that it met the specifications. It has performed faultlessly since and is a great asset to our property and gardan. Totally satisfied.
