Green Infrastructure

As climates change and more regions face severe heat and drought, municipalities all over the world depend on innovative techniques to harvest rain water, prevent stormwater runoff, and conserve water in general. Along with planting more trees, such efforts often include the construction of rain gardens and bioswales and the use of rain barrels and cisterns.

The benefits of capturing rain water are significant:

  • Conserve water
  • Improve water quality
  • Reduce flood flows and stormwater runoff that pollutes rivers
  • Reduce energy used to treat stormwater
  • Reduce greenhouse gases contributing to climate change
  • Reduce the need for imported water costing millions
