Tankless Underground Water Tank

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.

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.

The whole experience of converting our rarely used swimming pool into a rainwater tank and large vegetable garden with Tankless has been fantastic. Darren assisted in my application to Plan SA for the conversion to be done in Adelaide and provided all the technical information to make the planning and development applications run smoothly and efficiently. He then traveled over to South Australia for the installation including transporting the agricultural pipe in a huge truck as there were supply issues with the product in SA. Darren and Thomas worked incredibly hard over the 3 days of installation and were informative about the process, polite and neat- all I could have asked for1 I would highly recommend Tankless to anyone considering making their home and garden more sustainable.

Darren’s knowledge of tanks and communication make my job so easy and stress free. Darren was 1 of 4 installers I contacted to supply and install and after speaking to Darren I knew he was the man for my job. He installed within a week of contact and was the cheapest of the 4 quotes I received . I later found out Darren also installs artificial turf, after Darren’s work with my tank it was a no brainer for him to install my turf also. Again a simple process (cheapest and installed within a week). I recommend and will use Darren with all my future projects

We inherited this system when we purchased our home 9 years ago and it has worked perfectly all this time. We use it for watering the garden, washing the cars, topping up the pool and any outside cleaning jobs. Aesthetically much more pleasing than an above ground tank that’s for sure! Just had it serviced and checked- thanks Darren.

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 !

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.

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

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.
