We have used Coerco tanks and troughs for many years and have never had to replace any of them. With the extensive damage from Tropical Cyclone Seroja on the 11/04/2021 to fences, sheds and our home we are now implementing our succession plan which has us seeking out other Coerco products in their septic range of tanks and modular leach drain. More rain water tanks will also be utilised. From the Coerco agent in Northampton, the delivery driver, the fabrication workers and the management make a great team to deal with. Many thanks Coerco.

My tank was delivered very quickly and is excellent quality. The driver Tim, was very friendly and patient with me getting it in just the right spot. With his knowledge we were able to move it in place with just the two of us (I would recommend having more people to help though). Very happy with my Coerco tank!

I was super impressed by the delivery time. The tank arrived in less than a week and the driver was helpful and despite the difficult site, got the tank as close as possible. As a result of Coerco's efficiency I was able to have the tank in place in time to capture a 30ml downpour which half filled the 23,000 litre tank. Very happy with every aspect of the transaction and will be buying another Coerco tank

Over the years I've had a total of 8 tanks ordered and installed by Coerco on my property in Wilga and have been very happy, both with the product and the service I've received. Delivery arrangements were very flexible. The drivers/installers are very friendly and helpful when offloading the tanks. Some were rolled off their low-loaders and others were lifted into position with the onboard hydraulic crane. Both methods were great but the crane install I found to be the easiest. Highly recommended!!

“ Coerco were a pleasure to deal with. I had to put a hold on my order to ensure my building permit was squared away. Coerco were understanding about this.

" 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. "
