Pure Water Monterey to Receive Federal Grant

March 8, 2019

Monterey, Calif., March 8, 2019: Officials from Monterey One Water were informed the Pure Water Monterey Groundwater Replenishment Project has been selected for Federal grant funding. Once approved by Congress, the Project is set to receive a $4,184,193 grant.
After submitting an application in July of 2018, Monterey One Water and other water reclamation and reuse entities waited patiently to hear how $20 million in available funding through the Bureau of Reclamation’s Title XVI Water Reclamation and Reuse Program would be appropriated. The United States Department of Interior in consultation with the Office of Management and Budget awarded funds through a competitive ranking process. Of the 23 project applicants, six were awarded funding.
"To have the Federal Government recognize the benefits the Pure Water Monterey Project provides both the urban and ag sectors of the area is very gratifying," said Paul Sciuto, General Manager of Monterey One Water. Sciuto also noted, “To be recognized as one of the highest ranked projects is a testament to the collaborative thinking required to overcome the region’s water supply challenges.”
The Pure Water Monterey Project will diversify the area’s water supply through the production of advanced purified recycled water for groundwater recharge. The project will also increase the amount of recycled water produced for agricultural irrigation. As an area isolated from state or regional water systems, these additional water sources will help the Monterey Peninsula and Salinas Valley create sustainable water portfolios.
Dave Stoldt, General Manager of the Monterey Peninsula Water Management District stated, "A lot of effort went into this process, and that effort will directly benefit our communities. As grant funds reduce overall project costs, the cost of water proportionately decreases. Numerous meetings with federal officials over the past two years gave us opportunities to reinforce the importance of this project for our region. Those conversations really paid off.”
As part of the grant application package, Monterey One Water gathered 21 letters of support for the Pure Water Monterey Project. These letters were from a variety of local organizations, agencies, and elected officials, including Congressman Jimmy Panetta. In response to hearing about the award, Congressman Panetta stated, “The Pure Water Monterey Project provides comprehensive solutions to our regional water and development needs while supporting our conservation efforts. This isn’t just a significant investment by the Federal Government for this local entity, but an investment in our community and an investment in our future."

Why a New Name

June 12, 2018

Our Agency was established in the 1970’s to create a regional system for the proper treatment and disposal of wastewater—the used water that goes down your drains, like sinks, washers, and toilets. As a public agency, we are governed by a Board of Directors who represent our member cities and regions. 

Throughout the years, environmental requirements have changed and new technological advances have been developed. In response, the Agency has continued to adapt its processes to best meet the needs of the community. The greater utilization of wastewater led a committee of Board and staff members to investigate how the Agency could better represent its emerging roles in managing and developing water resources for the community. In 2017, the Board of Directors unanimously approved to change the Agency’s name from Monterey Regional Water Pollution Control Agency to MONTEREY ONE WATER to better reflect our efforts and vision for a water resilient Central Coast.

CORE PURPOSE   The Agency remains focused on safely treating the wastewater of our customers to diversify the area’s water supply and to protect the environment and public health.

WHY ONE WATER?   As our regional potable water supply decreases, we must look to innovative long-term solutions. This includes evaluating all water resources for potential reuse. Like many communities around the U.S. and throughout the world, this has led us to embrace the “One Water” concept which values all water regardless of its history.

WELCOME to Monterey One Water’s New One Exchange

April 10, 2018

Providing Cooperative Water Solutions

Spring 2018

We are excited to introduce Monterey One Water’s new One Exchange – a digital resource to provide a clear exchange of Agency progress, ideas, and updates for our communities. 
Monterey One Water, formerly known as Monterey Regional Water Pollution Control Agency, treats the wastewater of our customers and member entities, helping protect the environment and public health. This service is and will remain the core of our operations. Over the course of the last four decades however, our utilization of the treated wastewater has expanded to assist in diversifying the area’s water supply through recycled water production and groundwater recharge.

This month, we celebrate the 20th anniversary of the Castroville Seawater Intrusion Project (CSIP) and the Salinas Valley Reclamation Project (SVRP). Together with our partners at the Monterey County Water Resources Agency (MCWRA), we have successfully delivered over 80 billion gallons of recycled water to 12,000 acres of farmland in Northern Monterey County. This partnership is one way the Agency has assisted in providing cooperative
water solutions for agriculture in the Salinas Valley.

We also look forward to sharing other exciting news in future editions of One Exchange regarding the progress of Pure Water Monterey, a groundwater recharge project currently underway with our pure water partner the Monterey Peninsula Water Management District (MPWMD). This project is an important part of the water supply portfolio for the residents and visitors of the Monterey Peninsula, and we look to be producing water for recharge in the Seaside Groundwater Basin by the 3rd Quarter of 2019.

There is much communication to exchange regarding our area’s water supply, and we hope this new platform helps keep you informed.

Paul A. Sciuto
General Manager

Review: January 2018 Untreated Wastewater Release

February 27, 2018

On January 20, 2018, Monterey One Water (M1W) reported the unfortunate release of untreated wastewater into the ocean through its outfall pipe, which sits 2 miles off shore and 100 feet below the water’s surface. In response to the release, the Agency initiated an action plan based on the total of 4.9 million gallons of wastewater entering the Regional Treatment Plant during the timeframe of the release. After Agency staff reviewed the data and performed physical simulations of the incident, the final untreated wastewater release volume was calculated to be 2.87 million gallons.
What went out the outfall?
In the simplest terms, wastewater is used water. M1W predominately receives wastewater from domestic sources, coming from sinks, showers, washing machines, dishwashers, toilets, etc. Wastewater is over 95% water and as it moved through the outfall, the untreated wastewater mixed with other sources – treated wastewater and salt water from the California American slant test well, which are regulated waters routinely released to the ocean by M1W and other local  agencies. 
What happened to this wastewater?
As the combination of water sources traveled through the outfall pipeline, the dilution process began. A hydraulic model of ocean conditions and meteorological data at the time of the release estimated the dilution rate of 811:1 (811 parts ocean water per 1 part of wastewater). This dilution and mixing occurred in and immediately surrounding the outfall pipe. M1W laboratory staff sampled the surface water surrounding the outfall pipe within six hours of the release notification, and found no elevated levels of bacteria. In addition to sampling, the Agency contacted several area marine conservation centers that monitor animal health and no sick or injured animals were reported because of the release.
How did this happen?
The M1W Regional Treatment Plant is staffed 24 hours a day. Wastewater enters the Plant through a screen to filter out debris. As debris builds up, a rake clears the screen to keep water flowing smoothly. On the evening of January 19, the rake’s electronic control malfunctioned, and the alarm system did not alert the operator in the control room. The control room is the hub for everything happening at the Plant and the on-duty operator relies on continuous computer monitoring and alarms to maintain the Plant's operation. For employee safety during the overnight hours, the shift operator remains in the control room. As the screen became blocked, the water level in the holding structure rose and eventually overflowed into the ocean discharge pipe, bypassing the treatment plant.
What preventative measures have been taken?
Immediately upon discovery, the malfunctioning equipment was replaced and back-up systems were installed to ensure an event like this does not happen again. New redundancies include the installation of an infrared camera, satellite-based alert sensors that operate independent of the Plant’s computer system, and additional staff on the night shifts. In addition, M1W has worked with an independent consultant to complete a comprehensive evaluation of the equipment and procedures surrounding the event.            
What is the role of the Regional Treatment Plant and Monterey One Water?
Monterey One Water’s Regional Treatment Plant processes the wastewater of 250,000 people in the area. In its nearly 30 years of operation, this is the only incident of its kind to occur at the Regional Treatment Plant. Wastewater that enters the Plant normally goes through mechanical, biological, and chemical treatment processes.  The end result is safe, treated wastewater that meets or exceeds the regulatory requirements designed to protect public health, water quality, and the environment.
Treated wastewater then takes one of three paths: (1) the treated water moves to a third treatment process to become recycled water used by local growers to irrigate edible food crops like lettuce and strawberries, (2) the treated wastewater is released into the ocean through the 60-inch diameter outfall pipeline during periods when recycled water is not needed for agriculture, or (3) the treated wastewater will go through additional advanced purification processes once construction is completed on M1W’s new advanced water purification facility,  which will treat the water to a level  better than drinking level standards before being pumped into the ground for future urban use.
In 2017, M1W produced over 4 billion gallons of recycled water for reuse in the irrigation of crops, reducing the use of well water and benefiting the Salinas Valley Basin aquifer.
Both the staff and Board of Directors of Monterey One Water take this incident seriously. We are dedicated to serving our communities and customers, and we are committed to working with other agencies to enhance water supply sustainability and diversification for our region. The release evaluation process has been critical and will help the Agency assess our technology and procedures to ensure we remain a reliable and innovative community resource.
