What we engineer
Municipal and commercial water treatment design — conventional and membrane filtration, disinfection (chlorine, chloramine, UV, ozone), reverse osmosis, softening, and iron/manganese removal; industrial pretreatment systems and NPDES stormwater plans; backflow prevention assemblies per ASSE standards and cross-connection control programs; private well systems with treatment trains for arsenic, nitrate, PFAS, and hardness.
Compliance that passes review
EPA Safe Drinking Water Act compliance, state primacy-agency permits (DEP/DNR/DEQ), Lead and Copper Rule revisions, PFAS MCLs, and NPDES discharge permits — our PE-stamped plans and engineering reports carry treatment designs through plan review the first time.
