What we design

Water, waste, gas, and fixtures — Engides coordinates all of it for Rapid City projects. Our plumbing engineers design to the South Dakota code, account for Rapid City's severe winters and high winds in freeze protection and material selection, and produce riser diagrams and calculations that the Rapid City building department approves.

  • Freeze protection is non-negotiable with severe winters and high winds: we route Rapid City domestic and trap-primer piping inside the envelope, specify heat trace where exposure is unavoidable, and detail wall-hydrant shutoffs.
  • Below-grade plumbing gets special attention in Rapid City — sump and ejector sizing, flood-level rim elevations, and backwater protection where the the Rapid City building department reviewer will ask for it.
  • the Rapid City building department plumbing review in Rapid City, SD keys on isometrics, fixture-unit math, and gas sizing — our Rapid City sets include all three, drawn cleanly enough that corrections stay minor.
  • Rapid City defense and ellsworth support with process loads get engineered details, not catalog cuts — interceptors, separators, and specialty drainage drawn to the South Dakota plumbing code.
  • Water-efficient fixture selection for Rapid City defense and ellsworth support that still passes plan check: 1.28 gpf water closets, metered faucets, and the calculations the Rapid City building department wants to see in the submittal.
