Water Recycling
Sustainable Water Systems – Rainwater Harvesting & Greywater Recycling by Blue Industries Group (BIG)
Delivered by Blue Industries Group (BIG) – Specialists Serving Sussex, the South East and Beyond
As climate pressures increase and mains water becomes more strained, the way we use and reuse water must evolve. At Blue Industries Group, we help homebuilders, property developers, commercial facilities, and private homeowners take a smarter, more sustainable approach to water use.
Operating from our base in Sussex, we offer expert design, supply, installation, and maintenance of rainwater harvesting and greywater recycling systems across the South East of England — including Brighton, Crawley, Eastbourne, Worthing, Hastings, Guildford, Sevenoaks, Maidstone, Tunbridge Wells, Chichester, and surrounding areas.
For the right commercial projects or long-term partnerships, we also operate nationwide.
Rainwater Harvesting Systems
Contrary to popular belief, the UK doesn’t have water to waste. With increasing urban development, rainwater often runs off impermeable surfaces into overstretched drainage systems – contributing to flooding, sewage overflows, and wasted potential.
Rainwater harvesting systems allow you to capture that water at source – from roofs, driveways, or paved areas – and store it for later use.
Regulatory Requirements:
Rainwater harvesting is no longer optional. Under the latest Sustainable Drainage System (SuDS) standards, rainwater harvesting is now compulsory for almost all new developments in England.
We ensure all systems are fully compliant with:
- BS EN 16941-1:2018 – Rainwater harvesting system design and performance
- Building Regulations & SuDS national standards
Benefits of Rainwater Harvesting
- Reduce mains water usage for toilets, irrigation, washing machines & industrial processes
- Prevent surface water flooding
- Cut water bills in residential and commercial properties
- Reduce demand on ageing infrastructure
We Install
- Shallow-dug rainwater tanks (ideal for retrofits and small gardens)
- Above-ground and underground storage solutions
- Commercial-scale collection and reuse systems
Greywater Recycling Systems
Every day, litres of lightly-used water from showers, sinks, and washing machines are flushed away – when it could be used again. Greywater recycling systems collect, treat, and store this water, making it suitable for non-potable reuse within the same building or site.
We offer residential and commercial greywater systems, designed to suit your layout, needs, and sustainability targets.
Trusted Technology
We supply and install trusted systems such as Hydraloop, known for low maintenance, space-saving design, and reliable performance.
Whether standalone or paired with rainwater harvesting, greywater systems offer a powerful way to improve water efficiency.

Frequently Asked Questions
Is rainwater harvesting compulsory in the UK now?
Under updated SuDS standards, rainwater harvesting is now a required part of virtually all new developments in England. This change reflects growing concerns over water scarcity and drainage infrastructure and local authorities increasingly expect compliance at the planning stage.
What is BS EN 16941?
This is the UK and European standard for rainwater harvesting systems. It ensures installations are safe, effective, and suitable for long-term use. At BIG, we design and install all systems to meet or exceed this standard
How much water can I save with greywater recycling?
Hydraloop and similar systems can reduce water consumption by 25%–45%, depending on property size and usage. Particularly effective in multi-person households, high-occupancy buildings or frequent washing/showering.
Can greywater be used for drinking?
No. Greywater is only suitable for non-potable uses such as flushing toilets, garden watering, and laundry.
Can I add a rainwater or greywater system to an existing property?
Yes. We offer bespoke retrofitting options including shallow-dug tanks, compact system designs, and wall-mounted units for limited spaces.
