Underground Stormwater System
Southbury, CT · 2026 · Large-scale CULTEC chamber installation & site drainage
NYM Group installed a large-scale underground CULTEC stormwater chamber system, giving the property an effective way to manage runoff without giving up usable surface space. The scope ran from initial excavation and site prep through chamber installation, stone base, backfill, grading, and full restoration, coordinated phase by phase so the finished system tied cleanly into the property’s existing drainage infrastructure.
