GSPs Require Stakeholder Outreach

Developing groundwater sustainability plans (GSPs) requires solid technical analysis and a skillful stakeholder outreach and consensus program to successfully comply with California’s newly adopted Sustainable Groundwater Management Act (SGMA). Water purveyors, farmers, landowners, and resource agencies must determine the right amount of groundwater production for agricultural output on thousands of acres while maintaining municipal supply and…

Advanced Modeling Identifies Storm Drain Solutions

Cities in the Coachella Valley have a history of dealing with damaging summer flash floods. Intense thunderstorms can dump several inches of rain in a short time while runoff rushes from the nearby San Jacinto Mountains into the lowland flats where the cities are built. The City of La Quinta suffered back-to-back damaging summer storms…

Developing Bid Documents for CIPP Sewer Rehab

Many cities whose sewer systems were constructed in the first half of the 20th century are plagued by sanitary sewer overflows (SSOs) due to long-neglected root intrusion and pipe defects. To combat this, sewers can be rehabilitated using trenchless cured-in-place pipe (CIPP) lining. This    , and with far less public and environmental impact. Producing Thorough…

Do You Know the Difference Between Hydrology and Hydraulics?

Water is Earth’s most critical fluid in environmental processes and human life. When discussing stormwater management it is important to make the distinction between hydrology and hydraulics.  Some aspects of hydrology involve hydraulics but, in general, the two are very different.  Here’s how to understand these differences.

Will Your Flood Control System Work in a 100-Year Event?

Many California counties use the 100-year storm as the design storm for regional flood control facilities and stormwater related capital improvements. However new data show that storm will be more intense than previously thought.

Murphy’s Storm: Is Your Infrastructure At More Risk Than You Think?

Perhaps inspiring Murphy’s later pronouncement, mathematician Augustus De Morgan said, “Whatever can happen, will happen if we make trials enough.” At some point, your flood infrastructure will be tested by a storm event equal to or larger than the event it was designed to withstand.
