Rainwater Catchment

As the population growth on Vancouver Island and the outer islands has increased the demand on our aquifers, water restrictions have increased, and more municipalities and regional districts are requiring that a rainwater catchment system be incorporated into your development plan. Rainwater catchment is your viable method of collecting and storing free, non chlorinated water for a number of uses.


Do you

Want to irrigate with an alternate water source?

Want another source of usable water?

Have salt intrusion in your well?

Have water restrictions?

Have a dry well in the summer?

If you answered yes to any of the questions above, rainwater catchment may be your solution.


Benefits of Rainwater Catchment

  • Free source of non-chlorinated water
  • Water security promotes self sufficiency by increasing control over your water supply (ideal for municipalities with water restrictions)
  • Conserves water, which is environmentally responsible
  • Reduces stormwater runoff from homes and businesses
  • Can help to solve drainage problems on your property
  • Main source of drinking water after filtering, disinfection treatment
  • Modular in nature, allowing expansion, re-configuration, or relocation
