Static vs. Mobile Pure Water Systems


Whether you’re setting up a new window cleaning business, moving over to pure water window cleaning or upgrading your current pure water equipment – you’ll be faced with a decision over the kind of setup you go for. One of the key decisions is whether to go for a static or mobile pure water setup. We decided to look at the pros and cons of each with the aim of helping you to decide which is best for your business:

Static Pure Water System


A static setup is where your pure water system, or purification equipment, is installed in a fixed location, rather than in a vehicle. Water is purified and stored in this location, then transferred via a pump to your water fed pole system of choice – most commonly a van system, but it could also be a trailer or trolley setup.

Let’s take a look at the benefits of a static system:

Static Pure Water System - The Pros
You’re not restricted by a vehicle size or payload, meaning you can use a bigger tank and therefore store more water
You can return to base and fill up your water at any given time
You can be processing water even while out working with your water fed pole system
Your water production and storage is therefore not limited by size of your mobile tank
You can use a smaller tank in your van or trailer, which means less weight and more space for other equipment
Can be used to serve multiple vehicles
Eliminates the need to park and secure your van or trailer near a mains water supply
Usually easier to protect your filters and water from cold temperatures
Makes rainwater harvesting possible

After reading that, you might think that going for a static system is a sure bet, but there are other factors that you need to take into consideration:

Static Pure Water System - The Cons
Requires a secure production / storage area at your home or premises, with access to a water and an electrical supply
You require both a static and mobile tank, which increases the cost of the setup over mobile installs
You also need to invest in a transfer pump and hose
You need to be able to get your van or trailer reasonably close to your static setup for water transfer
You have to transfer water between tanks, which is not necessary with a mobile system
You have no ability to produce pure water anywhere other than at your static setup

If any of the above pros seem like unnecessary benefits for your business, or if any of the cons are likely to be problematic, it might be that a mobile pure water system will be more suitable for you:

Mobile Pure Water System


A mobile pure water system is where all of your purification equipment is installed in your van or trailer. The vehicle is connected directly to a water supply, where it purifies and stores the water on-board.

Mobile Pure Water System - The Pros
There’s no need for additional production and storage space - everything is contained within your vehicle
You have the ability to process water wherever your vehicle is, making onsite production possible and meaning you are less tied to your base
You only need one tank in your vehicle and there’s no need for water transfer equipment, meaning setup costs can be lower
It’s much easier to have your purification equipment installed by a professional

A shorter list of Pros you’ll notice, but they could be very key depending on your window cleaning business setup. Onto the cons:

Mobile Pure Water System - The Cons
You can usually only produce pure water when you’re not using the vehicle
The amount of water you can store is limited to the size of your tank and / or payload of your vehicle
You carry your purification equipment around with you, meaning a higher payload and less space for water and other equipment
The preceding two factors could mean a larger vehicle is required to store and transport the volume of water you require
You need somewhere near a mains water supply where your vehicle can be securely left for long periods of time
It’s harder to protect your equipment from low temperatures during winter
A mobile setup can usually only produce pure water for the vehicle it is installed in

In Summary

As we’ve seen, both static and mobile pure water systems come with positives and negatives – the importance of which will depend on size of your business and where it is based, the number of staff and vehicles you operate and the type of work you carry out.

To summarise, a static system is likely the best option if:

  • You need to maximise the production rate and storage volume of pure water
  • It’s not practical for your vehicle to access a mains water supply for long periods of time
  • You need to serve multiple vehicles

Mobile setups are best where:

  • Secure pure water production / storage space is not available or cost effective
  • A single vehicle is in operation and your daily water requirements are not large
  • Onsite or away-from-base water purification is required
  • You have easy and secure vehicular access to a mains water supply
