The NDS 313CR is a purple-colored professional-grade reclaimed water lid measuring 14 x 19 inches overall, with an 11 x 17 inch opening. Designed for use in reclaimed or recycled water irrigation systems, the purple color coding provides immediate visual identification at grade level, distinguishing reclaimed water access points from potable water infrastructure. This lid is installed by landscape irrigation professionals, municipal utility crews, and plumbing contractors working on non-potable water distribution systems. The cover sits over a valve box or access enclosure and is made to withstand surface traffic and UV exposure in outdoor installations.
The 313CR is suited for residential and commercial landscape irrigation applications where reclaimed water distribution is in use. The standardized purple color meets common industry conventions for reclaimed water identification, making it appropriate for projects subject to local reclaimed water use codes and utility requirements. It fits professional-series valve boxes with an 11 x 17 inch opening and is a common component in multi-zone irrigation system installations.
Designed as an OEM-style replacement lid for professional-series irrigation valve boxes with an 11 x 17 inch opening dimension.
Installation is typically performed by licensed irrigation contractors or plumbing professionals. Before servicing any valve box or reclaimed water access point, confirm the system is depressurized and the supply valve is closed. Ensure the lid seats flush and is properly secured to prevent unauthorized access or displacement by surface traffic. Local codes governing reclaimed water system identification and access should be verified prior to installation.
