Digesters.

Engineering Solutions for Dairy Digesters

4Creeks is at the forefront of providing engineering consulting services for an exciting opportunity available to dairies in California.  We work with Dairymen to understand their needs and conduct feasibility analysis to ensure a digester is a good investment opportunity.  If your dairy will benefit from a digester we offer start to finish assistance, beginning with conceptual site plans, assistance with grant preparation, and we specialize in permitting.  We work closely with the Water Board, Air District, and Counties to ensure the permitting process goes smoothly. Throughout our design process we work with the client to ensure dairy operations benefit from the design of the digester, and that it works seamlessly with current and future dairy management. Upon completion of construction drawings and specifications we assist the client with bidding and construction management.
