Rainwater harvest and reuse at a master planned community

Rainwater Harvesting

Rainwater harvesting techniques are growing in popularity as concerns increase over water supplies. Rainwater differs from stormwater, insofar as rainwater is collected from a roof or other surface before it reaches the ground. The many benefits of water reuse include: improved ground water quality and quantity, increased ground water tables, reduced strain on other water supplies, improved sensitivity to and connection with natural water cycles, reduced water costs, reduce flood flows, reduced top soil loss, and improved plant growth.

Rainwater collection systems can be designed in a variety of sizes and configurations, based on specific site considerations. They may include cistern-based systems and surface-lake collection systems. Everything from a rain barrel to US Bank Stadium’s enormous underground retention system.

Rainwater harvesting systems require careful planning in order to operate safely and properly. In our experience, planning should take into account at least these factors:

  • Soil conditions to facilitate water retention
  • Volume calculations for expected runoff
  • Catchment technologies
  • Proper equipment: coarse mesh, gutters, conduits, pump system
  • Storage facility
  • Flushing technology and methodology
  • Overflow management
  • Water reuse options, such as irrigation of nearby plantings and green spaces
