Rainwater Harvesting

Turn Rainfall Into a Valuable Water Resource.
Hydroxy helps homes, communities, commercial facilities and industries capture, store and make productive use of rainwater—reducing dependence on freshwater sources while creating more resilient and sustainable water systems.

Capture Water Where It Falls

Every roof, building and developed site receives water that can potentially be captured before it disappears into drains and stormwater networks.

Rainwater harvesting creates an opportunity to collect rainfall at the source, manage it responsibly and use it where appropriate instead of relying entirely on conventional freshwater supplies.

Capture the rain. Store it safely. Use it where it makes sense. By integrating rainwater into the overall water strategy of a property, organisations can turn a seasonal natural resource into a meaningful part of everyday water management.

Capture the Rain. Put It to Work.
A Smarter Journey for Rainwater

Rainwater harvesting is more than installing a storage tank. An effective system considers the entire journey of rainfall across the site.

Capture

Collect rainfall from suitable rooftops and catchment surfaces before it becomes uncontrolled runoff.

Separate

Divert initial runoff and unwanted debris to help protect stored-water quality.

Filter

Remove leaves, sediment and suspended material before or during storage.

Store

Provide appropriately sized storage based on rainfall availability, catchment area and expected water demand.

Use

Deliver harvested water to suitable applications through an appropriately designed pumping and distribution system.

Manage

Control overflow and excess rainfall responsibly when storage capacity is reached. Capture → Filter → Store → Use → Conserve

From Runoff to Resource - Changing What Happens After It Rains
Conventional Approach

Rainfall → Roof / Site → Drainage → Discharge. Rainwater rapidly leaves the property, while freshwater is brought back into the same site for everyday requirements.

More Sustainable Approach

Rainfall → Capture → Filtration → Storage → Productive Use.Instead of allowing every rainfall event to become runoff, suitable water can remain within the property and become part of its usable water supply.

Rainwater harvesting turns an occasional weather event into an opportunity for long-term water conservation.

Where Rainwater Harvesting Creates Opportunity
Buildings & Residential Communities

Large rooftops and common areas create opportunities to capture rainfall for landscaping, flushing and other appropriate shared requirements.

Reducing dependence on freshwater for these uses can make rainwater part of a more sustainable building-water strategy.

Hotels & Resorts

Hospitality facilities often combine significant roof areas with ongoing demand for landscaping, cleaning and utility water. Rainwater harvesting can help convert seasonal rainfall into a supplementary water resource for appropriate applications.

Commercial & Institutional Facilities

Offices, educational campuses, hospitals and public facilities can integrate rainwater storage with their overall water infrastructure to reduce dependence on external supplies for suitable non-potable demands.

Industrial Facilities

Factories, warehouses and industrial campuses can have substantial roof catchment areas. Captured rainwater can be evaluated for suitable utility, cleaning, landscape or process-support requirements depending on the required water quality.

Designed Around the Site, Not Just the Tank!

Effective Rainwater Harvesting Begins With the Water Balance

The amount of rainwater that can be practically captured and used varies from site to site. A meaningful rainwater strategy considers:

Catchment Area

How much suitable roof or collection surface is available?

Local Rainfall

How much rainfall occurs—and how is it distributed through the year?

Water Demand

How much harvested water can the property actually use?

Storage Capacity

What tank volume creates a practical balance between rainfall availability, available space and demand?

Water Quality

What level of filtration or treatment is required for the intended use?

Distribution

How will stored rainwater reach the points where it is required?

Overflow Management

What happens when rainfall exceeds available storage capacity?. Good rainwater harvesting connects rainfall availability with real water demand.

More Than an Alternative Water Source
Rainwater Harvesting Supports Water Resilience

Capturing rainfall creates value beyond the water stored inside a tank.

Reduced Freshwater Dependency

Using harvested rainwater for suitable applications can reduce the amount of freshwater required from external sources.

Better Use of a Natural Resource

Rain falling on a property becomes part of its water strategy rather than being treated entirely as runoff.

Reduced Stormwater Runoff

Capturing part of the rainfall from roofs and hard surfaces can reduce the volume immediately entering stormwater infrastructure.

Greater Water Resilience

Stored rainwater provides a supplementary source that can diversify a property's water supply.

Supports Water Conservation Goals

Rainwater harvesting complements broader efforts to reduce freshwater consumption and make buildings and facilities more resource-efficient.

Don't Let a Valuable Water Resource Simply Run Away.

Every rainfall event is an opportunity to capture water closer to where it will eventually be used.

Hydroxy brings water engineering, treatment and system integration together to help make rainwater a practical part of more sustainable buildings, communities and facilities.
