The Water Treatment Checklist – Commercial Edition

So you’re interested in a new or looking to upgrade your existing commercial grade water treatment system. That’s great, so to make your job easier, we have developed a checklist to help you know what is required.

What is your BUDGET?

It’s essential you have a budget in mind. Knowing your budget will help with the quoting process and ensure you get what you require within your financial constraints.

What TIME FRAME do you have for system installation?

It’s important to know what timeframe you require the water treatment system to be installed and operational. The supplier will need time to quote and, once approved, order all required products and materials and then install and commission the system.

What is your RAW WATER supply?

Where does your raw water source come from?

  • Town water
  • Bore
  • Dam
  • Tank

How is your TREATED WATER going to be used?

  • Drinking water
  • Irrigation

Is there a specific requirement?

Is the current water supply causing issues that need to be rectified? Your specific requirement will help decide to what level the water will need to be treated. 

Do you have an existing Water Treatment system? If so, what?

Is your current water treatment system underperforming? Tell us more about it, possibly it could be upgraded, saving you a total replacement cost.

What Continuous Flow Rate do you require?

The continuous flow rate will help with deciding what equipment will be required to maintain your usage requirements.

What is your Peak Flow Rate?

The “Peak Flow Rate” is defined as a sudden and sustained increase in the loading into a water treatment plant. Peak flows can be delineated into “instantaneous” (about one hour) or “sustained” (about 24 hours).

What is your daily water use in Kilolitres?

Your daily usage is essential to know. It is nearly impossible to know what size the water treatment system needs without knowing the daily usage.

Hours per day?

How many hours per day will the treated water be required?

Number of Days Per Week?

How many days per week will the treated water be required?

What is your current Mains Pressure, or what Pressure Pump/s are you using?

If you are using a Pressure Pump/s, please supply the make and model.

What is your available Constant Water Pressure?

To measure constant water pressure, attach a pressure gauge anywhere on the site on the water supply piping. Ensure no plumbing fixtures are running, and if a well and pump system serves the site, make sure that you have run the water until the pump starts running, then turn the water off.

What is your site’s Maximum Water Pressure?

The most accurate method is to install a pressure gauge making sure to have it installed by a certified plumber. Check the pressure when all water-using appliances are turned off to get a baseline reading.

What are your pipe size and material? 

Examples below:

  • PVC
  • Copper
  • Steel

Direct Online or supplied via storage?
