What is Rainwater Harvesting?

Rainwater harvesting is the process of collecting and storing rainwater for later use. Instead of letting rainwater run off, it is captured and stored for non-potable purposes like irrigation, landscaping, and outdoor cleaning.

Why Harvest Rainwater?

The purpose of rainwater harvesting is to capture and store a free, natural water resource. By collecting rainwater, you reduce reliance on municipal water supplies, lower water bills, and support sustainable water use.

How Can Rainwater Harvesting be Applied in Irrigation?

An 8 Days custom-designed rainwater harvesting irrigation system captures and stores rainwater—typically from rooftops—using gutters, filters, storage tanks, and pumps. This collected water is then used to irrigate lawns, gardens, and landscapes, reducing reliance on municipal water and lowering utility costs.

Rainwater harvesting systems can range from simple rain barrels to more complex setups with large underground storage tanks. These systems often include a pump hard-wired to your irrigation controller, allowing automatic irrigation using stored rainwater. Many installations also feature an alarm float system to monitor tank levels and notify homeowners or property managers when the water supply is low—especially during drought or extended dry periods.

Smart Planning for Rainwater Harvesting Irrigation Systems

Installing a rainwater harvesting system for irrigation requires careful planning to ensure long-term efficiency and reliability. When considering a system, keep the following key factors in mind:

  • Property size – Your system should be properly sized to meet your irrigation demands.
  • Backup water source – During drought conditions, a secondary water supply helps ensure uninterrupted irrigation.
  • Irrigation system components – Expert system design includes the correct components—such as updated scrubber valves—to ensure efficiency and system protection.
  • Float valve – Maintains proper water levels and prevents overflow.
  • Alarm system – Alerts you to system issues before they become costly problems.
  • Mainline filtration – A main filter protects your irrigation system from debris and contaminants.
  • Updated scrubber valves – Help prevent clogs and extend the life of your irrigation system.
