What to Look for

When it comes to greywater systems, they will be unique to each home with different requirements.

Before looking you need to consider: where you will be using the greywater, whether it is only for irrigation or for flushing toilets also; whether you want to combine the greywater system with a rainwater system; whether you are retrofitting the system or incorporating it into a new build; how much maintenance the system requires.

The Brand: Stormsaver are a company based in Nottinghamshire who want to provide people with sustainably sourced water.

They deliver both rainwater harvesting and greywater systems for commercial or domestic use.

The Product: The Hydraloop is a neat system that can recycle up to 85% of your water for toilet flushing, washing machine use, garden watering and even your swimming pool.

We love the self-contained system which can be both retrofitted or incorporated into a newbuild for households of up to 6 people.

This unit is unique as it is a complete greywater recycling system combining tank, filter, pumps and controls all in one unit. This gives the benefit of a quick installation and the smart machine even links to a smartphone app through wifi.

You do pay slightly more for the modern, compact machine with the price for supply and delivery of a Hydraloop Unit being around £4,500, not including installation, however as mentioned above this should be fairly quick.

This can range from £4,490 – £7,290, depending on tank size. This is a great option for anyone wanting to maximise efficiency from rainwater and greywater.

Both the greywater system and combined system will require installation. This could be done by a competent DIY-er or you can employ a professional to do the plumbing works.
