PrintRainwater Catchment System
Rainwater catchment systems allow you to capture runoff that would otherwise be lost to storm drains, storing it for future use. However, these are ‘active’ systems, meaning they require ongoing maintenance and effort to move the water where it is needed. For most residential landscapes, passive systems—such as swales and rain gardens—are a more practical choice. These earthworks slow and sink water directly into the soil, automatically hydrating your plants without the need for tanks or hoses.
Consider installing a Rainwater catchment system if you want:
- Reduce runoff, erosion, and potential flooding downstream
- Reduced water bills and utilize free water to irrigate your landscape
Quick tips for rainwater catchment systems:
- Check local regulations allowed criteria.
- Try to incorporate a first flush diverter into your system. They intercept and divert the initial, most contaminated rainwater (containing dirt, bird droppings, and leaves) away from your storage tank, ensuring only cleaner water is collected for use, reducing tank maintenance and health concerns.
- Rainwater catchment systems are classically easy to forget to utilize after the initial stage of excitement after installation. Consider having a plan for continued regular use or this feature may fill and become neglected. Neglect can result in overflowing systems, mosquitos, and missed opportunities for your landscape.
- Most systems are somewhat unsightly. Proper placement and screening are key.
