HERWIT provides services for all elements necessary to develop projects from ground zero through operations and completion of construction. These services include: overall project management, initial site assessment and selection, management of the California Environmental Quality Act (CEQA) permitting, negotiation and preparation of National Pollution Discharge Elimination System (NPDES) discharge permits, preparing other permits and Army Corps of Engineers permits, Department of Fish and Game stream bed alteration permits, development of pre-design reports and preliminary cost estimates, final design of all mechanical, electrical and civil facilities, bidding support services, construction management, engineering support services during construction, and startup and operations assistance.

The partners, Gregory Harris and Kurt Gardner have presented cutting edge technology for the design of treatment and conveyance systems at national conferences in Dallas, Chicago, and New Orleans, as well as at local conferences in Sacramento, Reno, Las Vegas and Salt Lake City.  Together, they have used the combination of their multiple engineering disciplines and their extensive project management and design experience to plan, design, and construct treatment and conveyance systems from single pump stations to complete treatment plants.
