Frey Engineering has evaluated and designed sanitary and industrial   waste water treatment systems for a number of private clients.  We provide value  engineering studies to formulate solutions that are implemented into the   design.  We offer permitting support for waste water discharges, treatment works   approvals, and construction permits.  We also will evaluate waste water  recycling  options for properties with waste water discharge limitations.
