Select Water Tanks Google Review Lisa Hagean 

"I recently ordered a 7500 litre stainless steel round tank from Select Water Tanks and couldn't be happier with it. The process from order to delivery was perfect and I was kept in the loop with manufacture times and a set delivery date. Communication was great through the process and I had to change the delivery date to suit me and there was no issue with this.."

"The team from Select Water Tanks were superb. The way they handled my new tank was especially careful and thorough. It was great watch them take it down a hill and locate on the site. Highly recommended for good product, service and interest in the customers needs."

"We have just bought 3 tanks and have now installed them. We found Select Tanks very easy to work with right through to delivery. We had to change the delivery date on a number of occasions and it was never a problem. We are very happy with the quality of the tanks which look great."
