How big is a 5000 Litre Slimline Water Tank?

Although there are many different variations in size, most 5000 Litre slimline water tanks are around 3m long and 1 meter wide. The height is usually around the 2.1 meter mark. The problem with going either too narrow is is blows the length out to four or five meters. This not only makes them impracticable to fit on site, but also is a manufacturing issue as most ovens where 5000 Litre slimline water tanks are made are not big enough to accommodate.  The Rotoplus S-Line 5000 Litre slimline tank is 2900L x 1000W x 2100H and comes in over 20 different colours. It comes with two outlets on each end for ease of installation.

How much does a 5000 Litre Slim Tank Cost?

Water tanks prices differ for many different reasons. Most tanks these days are Australian made and we encourage all customers to buy locally made 5000 Litre Slimline Water Tanks. The average price for a 5000 Litre tank is $1550 – $1800. The biggest reason why some tanks are significantly more expensive is because those manufacturers may choose to include freight in the cost of the tank, and deliver either state wide or a very large area. The Rotoplus 5000 Litre slimline tank is priced very competitively as the tank is made here in Melbourne and we use our own delivery drivers to deliver in and around Melbourne. Our Melbourne 5000 Litre slimline tanks can be delivered with six units on a load to a single site. Going into rural and regional towns, we can deliver these tanks very cost effective and drive the price down of the cost of the 5000 Litre slimline water tank delivered to you. We even deliver this tank to Sydney and Canberra as well as Central Coast and Newcastle. Call us for a quote.

How heavy is a 5000 Litre Slimline Water Tank?

Most 5000 Litre slimline tanks weigh between 180kg and 200kg. Although the weight of the tank is important to determine the wall thickness of the tank, it is more important to know what the wall thickness is of the 5000 litre tank in particular areas. This is done by using ultrasonic detectors to determine the wall thickness. As part of the Australian Standards, all our tanks are tested to make sure they have the correct wall thickness as required by Standards Australia. When you buy a 5000 Litre slimline water tank from ASC Water Tanks, you can buy with confidence.
