The Highest Rated Poly Water Tank Manufacturer... By Customer Reviews!

" Great team with efficient delivery that places tanks in the spot you want. Strong tanks which will last in the environment we throw at it. Won't buy another brand as they just don't last. Have bought numerous tanks from Coerco now and making me happy as so will be buying more in the future. First to have a tank over 22,500 litres which you need to keep water up to the big spray rigs out there now. Look forward to my new Flexi n tank, a first for me from you guys. I am sure it won't disappoint. Thanks! "

Murray McDonald, Kellerberrin, WA

" Purchasing a water tank for the Kendenup fire brigade, I received excellent service from all members of the Coerco group with whom I liaised. They have a terrific receptionist in Carly who is exceptionally courteous and welcoming, sales staff member Brayden was very helpful and prompt in all communications and their carrier was helpful in the delivery and locating the tank correctly on site. A terrific company who I would highly recommend. Thanks to all concerned. "

Joe Kelly, Perth, WA

" I had two 32,000 litre tanks ordered and delivered and I'm very happy with them and the delivery. "

Rick Bee, Narrogin, WA

" Amazing service! delivered faster than expected, exactly as ordered and all wrapped and in perfect condition. Definitely recommend COERCO, great job. "

Warren Arnold, Kalamunda, WA

I had a fantastic experience with these guys. I ordered 4 x 3,000 litre slim line tanks, they delivered to the Perth metro in record time.
I did have one issue with a fitting that wasn't quite right, a quick phone call saw a technician come out, make a few mods with some top notch tools and all fixed up.
Staff that I dealt with were friendly and knowledgeable.
No hesitation, 2 thumbs up.

" Really happy with the service & communication we received from Coerco throughout the whole purchase and delivery and not forgetting the great tanks as well. Alex their delivery driver is a legend as our tanks placement location was a very tricky one and nothing was a problem for him and he stayed until the job was fully completed. Would recommend these guys 100% "
