Irrigation Enclosures

Irrigation systems support the health and vitality of landscaped areas by ensuring plants receive consistent watering, especially during the establishment period. Irrigation enclosures are a critical component of irrigation systems. The enclosure houses a water meter to monitor water usage and a reduced pressure zone (RPZ) backflow preventer, which is required to safeguard against water contamination. By enabling automated irrigation and reducing maintenance demands, irrigation enclosures play a vital role in maintaining vibrant, sustainable streetscapes. Proper siting is crucial to minimize visual impact. Review Watering and Irrigation
