HydroScience is expanding.

We're pleased to announce the opening of our fifth HydroScience office, located in Carlsbad, California, and led by Regional Manager Robert J. (Jud) Warren, PE, BCEE. Jud will be leading our efforts to provide water, wastewater, and recycled water engineering services in Southern California. 


Jud has close to 40 years of project delivery experience for clients throughout the Western United States, and most recently in San Diego County. He will be backed by the full resources of our engineers and support staff in our other HydroScience offices. Led by Jud, HydroScience looks forward to implementing our mission of providing the highest quality work for our clients in this new region—the first time and every time.
