Water Tank Size Calculator

This calculator is designed to provide you with guidance on the tank size you require based on your capacity requirements. Tank size output is available in three capacities, nominal capacity, actual capacity & actual useable capacity.

Note: Please click on the ? symbols for explanations for each category.

The calculator is based on hot press IFB sectional and one piece tanks complete with float valve housing and up elbow overflow arrangement with 3” outlet. Please note actual and useable capacities are typical and for guidance purposes only.

Have you considered a TIF Tank for further customisation?
Totally Internally Flanged tanks are fully customisable with less external space needed for installation, maximising the space available.

How It Works

What this calculator is doing

01

You enter a capacity

Choose whether that figure is nominal, actual, or actual useable – the calculator adjusts its matching accordingly.

02

We match it to TRICEL models

The tool compares your figure against typical one-piece and sectional tank sizes and filters by any space or weight limits you’ve entered.

03

You confirm with our team

Every site has details a calculator can’t see. Send your result to Tricel and we’ll confirm the exact model and provide a drawing.

Common Questions

FAQs

What does the Water Tank Size Calculator do?

It takes a required storage volume in litres and suggests Tricel one-piece or sectional tank models that could match it, along with approximate dimensions and weight. The result is a guide to help early planning – contact Tricel directly to confirm the exact model for your project.

Nominal capacity is the tank’s labelled size. Actual capacity accounts for the tank’s real internal shape. Actual useable capacity is what the tank holds day-to-day once float valve operation and freeboard are taken into account – usually the most realistic figure for planning.

These optional fields narrow the suggested models to ones that could physically fit and be supported at your site. They don’t replace a structural assessment – Tricel’s team can confirm feasibility for your building.
