The Highest Rated Poly Liquid Transport 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

" Had a 50kl tank delivered last week. Some issues with getting road train into my block. Michael the driver was excellent in making sure i got what i needed and was a satisfied customer. "

Joe Kelly, Perth, WA

" We have been very happy with the polyethylene septic tanks provided by Coerco, and we now use these as standard on all our new homes. Previously we used concrete tanks which were much heavier and needed machinery to lift them. We generally needed two concrete tanks compared to the one poly tank with a baffle which we now use as standard. This means we can install them faster, with less work, and less digging. We find the sales staff at Coerco to be very helpful, knowledgeable, quick to act, and professional in every respect. I would certainly recommend Coerco as a company. "

Andrew Sharpe - Stallion Homes, Northam, 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. "

Brian Appleby, Kendenup, WA

" As an agent for Coerco they are so easy to deal with making it even easier for the customers. Nothing is an issue for them. "

Craig Bassett - Elders Ltd, Geraldton, WA

" Fantastic Experience. The service was 10 out of 10, and the process was seamless from quote through to delivery. Was even more impressed after getting an after sales follow up call to make sure I was happy. "

Darren Tindal , Albany, WA

" Coerco have always been our go-to supplier for poly tanks. Good quality tanks. We've requested to customise the tank fittings and were executed well. Great customer service, always prompt in responding to queries and requests. "

Jerica Marise Razon , Malaga, WA

" Great service for my project. Delivery drivers very professional and product first class. "

Adam Van Nellestyn , Busselton, WA

" 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% "

Cy Bettjeman , Brunswick Junction, WA

" Extra special thanks to the team at “Coerco”. I bought a full septic system and leach drains from them for my 40 acre property in Gingin. I can’t speak any higher of them from the people in the office to the delivery. Products are very very good and the people even better. I would highly recommended these guys to anyone chasing the products they stock! You won’t be disappointed. "

Sarah Kelly , Gingin, WA

" Product is excellent, price was right, and the fella who dropped the tanks off was a good bloke, all in all a can do no fuss company. You'll have no dramas here 👌 "

Louie Hughes, Munglinup, WA

" This is tank number 6 from Coerco (formerly rapid plastics) over the last 20 years and I won't go anywhere else for a quality tank.
The customer service is excellent, receptionist Brianna was efficient and dealt with my query about delivery times in a very professional way, Denise endeavoured to match the delivery of the tank with my needs, very courteous with a "can do" attitude.
Delivery was excellent, the driver contacted me twice to make sure my time wasn't wasted waiting at the gate. He was organised and helped put the tank on my trailer, rather than drop it off an drive away.
Overall a top company to deal with, with a great reputation. Can't wait for tank number 7! "

David Stalker, Bindoon, WA
