Xylem - Water Scarcity – What can we Do?

Water Scarcity - Environment Agency - Water Treatment - Booster Pump

Xylem - Water scarcity

Water. It’s the world’s most precious resource, and yet the Environment Agency’s findings suggest that three billion litres of it is lost through leakage every day.[¹] The report also warns that if our habits don’t change, England could face water supply shortages by as soon as 2020. So what can we do to help prevent this from happening? Here, David Spragg, DBS OEM Business Manager at Xylem Water Solutions, considers how having a treatment and reuse solution in place is one way to help safeguard our supplies.

We are told time and time again of the very simple ways in which we can reduce our personal water consumption. These include: having shorter showers, turning the tap off when brushing your teeth (a running tap wastes approximately 6 litres per minute)[²] only using the dishwasher when it’s full and using a watering can in the garden rather than a hose. However, as a society, our habits speak volumes about the way we view water and the relaxed attitude we still have towards its usage. In fact, according to Waterwise, the average UK homeowner uses approximately 150 litres of water a day, which is around a tonne a week.

It’s clear that attitudes need to change, but perhaps so too does the approach. Making small tweaks to our daily habits is a brilliant place to start, but a more permanent change would help even further to prevent the anticipated shortage. There are supplies of water that could be used to help relieve the water stress, and one area less frequently considered in a residential environment is water treatment and reuse. This is where a solution like Xylem’s HydroInfinity Residential can make all the difference.

The complete water treatment and booster system for private and shared water supplies, including schools, offices and medical practices, treats water to independently verified drinking standards, using unique H2Ozone patented technologies to deliver UV treatment, ozonation and filtration. The fully-integrated solution is the first of its kind and the only chemical-free water purification system available that inactivates all pathogenic organisms from the water supply, including E.coli, Salmonella, Legionella bacteria and the Cryptosporidium oocyst.

It works by collecting, purifying, storing and distributing water from a variety of sources including: rainwater, wells, surface water, boreholes and municipally supplied water. Only the purest water is delivered, with bacteria levels below that of bottled water. The electric sensors, remote control systems and software automatically monitor and ensure that no compromised water enters or exists in the system.

Xylem - HydroInfinityFirstly, water is harvested and collected through a washable stainless inlet pre-filter at the top of the system. It then flows to a second inlet filter, which traps any particles larger than five microns. Next, the water passes through the ‘Helical’ UV chamber, where all pathogens are deactivated. Thanks to the unique design, the speed of the water can be controlled to ensure it is fully treated and sterilised before being moved to the ozonation stage.

The ozone is generated and passed through a diffuser, where it comes into contact with the stored water in the tank. It is then pressurised in the piping network, where it is maintained up to 4.5 bar. The treated water is stored in the tank until needed. During this time, the ozone will keep the water clean and fresh, and the Oxidation Reduction Potential probe will monitor levels. In addition, the tank is fitted with a water level sensor, which will alert the machine when levels fall below 160 litres, and automatically refill to its capacity of 220 litres.

The H2Ozone patented technology in HydroInfinity, which takes less than two hours to install, also has a Wi-Fi and 3G option, which allows 24/7 remote access monitoring and provides full visibility to the pump and tank’s operation, as well as offering predictive analysis. A further added benefit is that the system has an inbuilt pump, so for those who suffer with low water pressure, it provides an added boost for the house.

While a system like this won’t eradicate all water shortage woes, being responsible and making best use of the water available through treatment and reuse is certainly a step in the right direction.
