Highlights

Highlights

  • All lawn irrigation systems require a permit from the Building Inspection Department.
  • Potable interconnections with alternate water sources are prohibited.
  • If reclaimed water is involved, Arlington requires both a reclaimed-water-side double check assembly and an RPZ on the potable side.
Workflow

Workflow

  1. Pull the irrigation permit before installation work begins.
  2. Install the assembly to Arlington's plumbing, irrigation, and backflow code requirements.
  3. Use the City testing and reporting path once the device is installed or later repaired.
Residential

Residential

  • Residential owners most often run into Arlington's rules through lawn irrigation permits and re-occupancy or repair testing triggers.
  • A homeowner should not flatten Arlington into a generic annual rule because the ordinance splits health-hazard annual testing from other event-based triggers.
Commercial focus

Commercial and managed properties

  • Commercial and other higher-hazard premises are much more likely to sit in the annual testing lane.
  • Fire protection, inspection access, and City registration requirements make Arlington more ordinance-heavy than a generic plumber quote suggests.
