Standard Tanks:    Open PDF Diagrams of Standard Tanks

Our tanks have been manufactured for and fitted to just about every type of Recreational Vehicle from small camper trailers to luxury motor homes to sailing boats, houseboats, and world cruisers.

How do we compare on price? "Generally" speaking our fabricated tanks are about 2/3 to 3/4 of the cost of stainless steel and our standard tanks are about 1/2 the cost.

All tanks come standard with an inlet, outlet and breather port threaded. Generally, turnaround time is 10-15 working days from receipt of firm order.

We use a unique construction method to ensure the highest possible tank strength. The method includes a wrap/fold and double weld, the result is a tough durable tank. Our water tanks are made of Polyethylene which is corrosion and oxidisation free. This is particularly important in marine applications and under-vehicle uses where the tank may be exposed to corrosive conditions.

There are no compromises with our tanks, you can have any fitting anywhere you’d like. This is also a huge benefit when matching existing or adding additional storage capacity.

No smelly water, no discolouration of water and no rust or metallic pieces in your drinking water. Atlas Tanks are made of Food Grade Plastic so your drinking water will taste as it should.
