Regional basin study1602wwres P03

The Bureau of Reclamation has released the Southeast California Regional Basin Study, which evaluates options to resolve water supply and demand imbalances within the Borrego, Coachella and Imperial Valleys in southeastern California in the face of uncertainty due to climate change. Reclamation partnered with the Borrego Water District to develop the study, with contribution from the Coachella Valley Water District, Imperial Irrigation District, San Diego County Water Authority and other interested regional stakeholders. Among other findings, the study noted that the Borrego subarea aquifer, which is recharged solely by groundwater, may be depleted in 50 years.

Grit cost calculator1602wwres P02

The Cost of Grit Calculator from Hydro International has been developed as a universal online resource. It draws on real-world data collected from operating plants to predict the likely savings to treatment plant efficiency that can be gained for any operator installing a high-performance grit removal system, using the guiding principles of Advanced Grit Management®. Having set the operating plant capacity and the preferred equipment lifetime cost into the system, users can input estimated or known costs of their downstream plant maintenance activities. These include the periodic cleanout of grit basins, aeration basins, or anaerobic digester tanks, for example, as well as replacement and refurbishment costs for equipment such as pumps, centrifuges or membranes.
