Domestic Water System Engineering

Domestic water system engineering designs the supply, distribution, and hot water systems that deliver potable water throughout commercial and multifamily buildings — confirming adequate pressure and flow at all fixtures, designing pressure-boosting where needed, and engineering recirculation systems to deliver hot water without waste.
