We design and implement commercial rainwater harvesting systems that help estates and facilities collect, store, and reuse rainwater.
Rainwater harvesting can form part of a wider approach to water efficiency, sustainability and practical facility management. Captured rainwater can be stored and reused for suitable non-potable applications such as toilet flushing, irrigation, external cleaning or grounds maintenance.
We can create a bespoke rainwater harvesting facility with adaptable tank capacities designed to capture anything from 10 to 20,000 litres of rainwater.
Bespoke rainwater harvesting systems for commercial facilities
Commercial rainwater harvesting systems collect rainwater from suitable surfaces, store it and make it available for appropriate reuse.
For businesses, facilities and project environments, this can help reduce reliance on mains water for non-potable uses and support wider sustainability goals.
Westwood can provide practical plumbing and system support for rainwater harvesting projects where the application, site conditions and intended use are suitable.
Containerised rainwater harvesting facilities
One of our most distinctive rainwater harvesting solutions is a bespoke facility housed in a shipping container.
This type of containerised approach and out-of-the-box thinking can provide a practical, adaptable solution for commercial sites, facilities, or project environments where rainwater capture and storage need to be considered as part of a wider site setup.
Tank capacity can be adapted to capture anything from 10 to 20,000 litres of rainwater, depending on the system requirements.
Potential commercial uses for harvested rainwater
Depending on the site, system and water quality requirements, harvested rainwater may be suitable for non-potable applications such as:
Toilet flushing
Irrigation
External cleaning
Facility washdown
Grounds maintenance
Suitable commercial process uses
Every project should be reviewed properly to understand the intended use, tank size, filtration requirements, pump requirements, and installation practicalities.
Any use involving drinking water would require appropriate treatment, testing, and compliance checks.
Supporting sustainable facilities
Rainwater harvesting can work alongside wider commercial plumbing, heating and renewable energy considerations.
We already support commercial plumbing, plant rooms, renewables, and specialist project environments, allowing us to advise on rainwater harvesting in the context of the wider facility.
Suitability review and practical advice
Not every site will be suitable for rainwater harvesting. Factors such as roof area, collection surfaces, available space, tank size, water demand, intended use, access and maintenance requirements all need to be considered.
Westwood can help review these practical considerations and advise on whether a rainwater harvesting system may be suitable for your commercial facility.
