3.5.3 Rainwater Harvesting
Rainwater harvesting provides an alternative source to supplement or replace purchased water for irrigation. Catchment may be employed through several strategies:
- TxDOT facilities with architectural components may capture runoff from rooftops and store in above- or below-ground cisterns or collection tanks. This may be pumped as needed to irrigate the site. The TxDOT Hill County Safety Rest Area, south of Hillsboro, is an excellent example of this combination of architectural design and water conservation. An example of a rainwater harvesting system is shown in .
