The awards recognize the achievements and excellence of five wastewater treatment facilities in the region. These awards also reflect the strong commitment to improving water quality in the Bay by the Bay Area Pollution Prevention Group (BAPPG) and BACWA (Bay Area Clean Water Agencies). “The public has a right to expect treatment plants to treat wastewater to make it cleaner and safer,” says Michele Pla, BACWA Executive Director. “What they may not realize, is that wastewater agencies are working in the community to prevent pollutants from ever reaching the treatment plants.” The goal of the Water Board’s Pollution Prevention program is to reduce the mass of pollutants that reach the environment and threaten water quality by way of the sewer, the storm drain, and solid waste. “When there is a reduction in pollutants coming to the plant, it means that public agencies, businesses, and residential communities have worked together to reduce waste,” says Bruce Wolfe, Water Board Executive Officer. “The Water Board is pleased to recognize the outstanding efforts of the five winners.” Mt. View Sanitary District, which serves parts of the City of Martinez and the eastern portion of unincorporated Martinez, received an award in the category of “Outstanding Public Outreach.” Mt. View Sanitary District is a leader in developing educational programs and teaching manuals to educate children about pollutants and how they enter the environment. The Mt. View Sanitary District collaborates with the Lindsay Wildlife Museum to conduct an extensive county-wide pollution prevention education and outreach program to over 1,500 third, fourth and fifth graders each year. The Mt. View Sanitary District has developed model educational references about local marsh ecology, aquatic and terrestrial field guides for children, sewer science, and pollution prevention alternatives for the home. 2005 Plant of the Year Award In February 2006, the Mt. View Sanitary District was chosen Treatment Plant of the Year for 2005 (Small Plant) by the San Francisco Bay Section of the California Water Environment Association. This prestigious award is based on compliance results, innovative practices, cost effectiveness and the evidence of superior plant operations. The District has been honored in the past with this award in 1977, 1995, 1996, 1998 and 2001. Public Education Award In February of 2006, the Mt. View Sanitary District was awarded the Public Education Award for 2005 by the San Francisco Bay Section of the California Water Environment Association. Dave Contreras, District Manager for the Mt. View Sanitary District, accepted this award for the continued excellence in public outreach and interpretive center programs originally established in 1996. These two Awards were featured in an article printed by the local newspaper Martinez- News Gazette, Weekend Edition , February 4-5, 2006. Follow the link provided to a pdf version of the front and twelfth page of the weekend edition. 2004 The Associations of Bay Area Governments recognized the Mt.

Diablo Wetlands Fund Connecting Kids with Wildlife Wastewater Treatment Treatment Process Sewer Collections Laboratory Testing Wastewater Treatment Treatment Process Sewer Collections Laboratory Testing Process Screenings Removal Clarification Biotower - Nitrification Secondary Clarification Clarification Sand Filtration Sand Filtration Screenings Removal The wastewater passes through an Aquaguard Screen® removal system which uses bar screens to remove large debris which could damage plant equipment, located further downstream. This debris is cleaned and hauled to an approved land fill. Primary Clarification The clarifier slow the flow allowing heavy particles to settle to the bottom of the clarifier tank. The solids or sludge are pumped to the sludge thickener for further treatment. Biofiltration The biofilter continually distributes water from the clarifiers over rocks which provide a home for microorganisms that break down organic material into simpler inorganic chemicals. The biofilter conditions mimic the environment of rocky stream beds and ocean coasts. Biotower-Nitrification The biotower distributes the water over sheets of corrugated plastic (Cross-Flow Media). Bacteria living on these sheets convert ammonia in the wastewater to nitrates, a form of nitrogen that is non-toxic. Secondary Clarification The clarifiers slow the flow allowing heavy particles to settle to the bottom of the clarifier tank. The solids or sludge are pumped to the sludge thickener for further treatment. Sand Filtration The Mt. View Sanitary District utilizes a Dynasand ® filter system. The system removes solids from the secondary effluent achieving a clarity that allows downstream disinfection with ultraviolet light. The Dynasand ® filter is a continuous-backwash, upflow, deep-bed, granular-media filter system. The filter media is continuously cleaned by recycling the sand internally through an airlift pipe and sand washing. The cleansed sand is redistributed on top of the sand bed, allowing for a continuous, uninterrupted flow of filtrate and reject (backwash) water. Ultraviolet Light Disinfection Mt. View Sanitary District was the first POTW (Public Owned Treatment Works) operated in Northern California to use ultraviolet light for disinfection on a full-scale operation. MVSD has been able to eliminate the use of gaseous chlorine, sulphur dioxide and all Acutely Hazardous Materials (AHMs), which can be toxic to both humans and wildlife. The UV system uses the same ultraviolet light found in sunlight, but in a concentrated dose, to destroy harmful microorganisms present in the wastewater. The elimination of AHM’s from the plant premises has increased staff and public safety while decreasing District liability. Outlet to the Marsh The treated effluent flows into a series of marshes, rather than a deep-water outfall as most treated wastewater does. These marshes, enhanced by the reclaimed effluent, are rich and diverse in wildlife and easily accessible to students, birders, researchers, and the general public. To learn more about these wetlands, click here . Sludge to Biosolids Clarification Sludge thickener Sludge Digestion Sludge Dewatering Biosolids Sludge Thickening The Gravity Sludge Thickener is another settling tank that further separates solids from the liquid. The sludge from the bottom of the thickener is pumped to the Primary Digester. The overflow of water from the thickener is sent back to the influent wet well. Sludge Digestion Sludge solids are pumped into anaerobic digesters where bacteria, in an oxygen-free environment, break down solids, producing methane gas, carbon dioxide, and stabilized organic solids. The methane gas is used to fuel the plant boiler which maintains the desired temperature in the digester for the bacteria to thrive. Sludge Dewatering The Mt. View Sanitary District uses an Alfa Laval Sharples® Centrifuge. A centrifuge spins at a very high speed, forcing water and solids to separate. With this unit, we take sludge that is about 2% solids and remove water to increase it to approximately 20% to 25% solids. The water is returned to the influent wet well for treatment and the solids are sent to a landfill. The centrifuge enables us to achieve a high solids concentration, reducing hauling costs. Biosolids Solids from the centrifuge, which are called biosolids, are used as alternative daily cover at a landfill. Copyright © 2026 Mt.
