For generations we have treated rain as something to get rid of.
As quickly as possible, we channel it from our rooftops into drains and sewers, believing the faster it disappears, the better.
But our climate has changed.
Rainfall is becoming more intense. Drainage networks are under increasing pressure. Communities are experiencing more flooding, more sewer spills and increasing pressure on precious water resources.
Building bigger infrastructure alone cannot solve these challenges.
Every rooftop is an untapped rainwater asset. By managing rain at source before it enters the drainage network, we can reduce pressure on our sewers, reduce flooding, protect our rivers, and build more resilient communities.
That is why Our Rainwater exists.
We are transforming the way rainwater is managed by helping water companies, local authorities and communities work together to manage rainwater intelligently. We know that every location is different. There is no one-size-fits-all solution.
Rainwater infrastructure shouldn't simply be installed. It should be intelligently designed, actively managed and continuously improved.

Use modelling to identify the right solutions in the right place.

Work with communities so they are part of the solution for long-term impact.

Monitor performance over time so every project continues to learn and improve.
Creating resilient communities starts with all of us.
If you believe every rooftop has the potential to make a difference...
If you believe the future starts at the source...
Join us.
Because the future starts at the source.
