Designed to blend discreetly with your surroundings, and manufactured tough to last for many years, our liquid storage solutions will help you save money and offset environmental impacts.

When it’s time to build, build with Promax. Above ground, or underground, we’ll fit right in. 

Over the years we’ve come across most situations in Water Storage and love working with our clients to design a solution which helps them achieve their specific objectives. Our team are ready to discuss your needs and create custom solutions for you.
