After the completion of third-party validation testing under the National Water Research Institute (NWRI) Guidelines, TrojanUV recently announced that its open-channel wastewater ultraviolet light disinfection system TrojanUVSigna™ has received conditional acceptance from the California Water Board’s Division of Drinking Water (DDW) Recycled Water Unit (RWU). The TrojanUVSigna is the first and only 1000 Watt low-pressure high-output-based UV system to obtain acceptance from the DDW RWU, and meet the strict coliform and virus disinfection criteria found in Title 22 of the California Code of Regulations for recycled waters.

“The reuse of wastewater treated to very stringent levels for non-potable applications continues to gain widespread support, and is being adopted by municipalities throughout the world as a means of achieving a sustainable water supply,” says Wayne Lem, market manager, Trojan Technologies. “This Title 22 approval is an important milestone for us, and it now gives municipalities in California the option to confidently choose a compact, cost-effective UV system for their wastewater reuse projects.”

In addition to microbiological performance testing, the TrojanUVSigna has also received third-party approval for lamp age testing and cleaning system effectiveness per NWRI guidelines.

The City of Jackson, California will be installing the TrojanUVSigna at its wastewater treatment plant in Amador County. It will be utilized to disinfect four million gallons of wastewater per day to stringent reuse limits, and will play an important role in improving the City’s wastewater effluent quality and ensuring effluent entering Jackson Creek and Lake Amador meets applicable standards.

TrojanUVSigna incorporates innovations, including TrojanUV Solo Lamp™ Technology, to reduce the total cost of ownership for disinfection and drastically simplify operation and maintenance. It is the ideal solution for wastewater treatment plants in need of advanced UV technology.

CWEA member Michael Hansen, the Acting Deputy Public Works Director for the City of Eurkea, makes the case for investing in the treatment plant and sewer system. Rates will increase over a 5 year timeline.

“You have the harshness of the saltwater air on the outside that’s attacking everything. Then from the inside, there’s  sewer gases constantly working and chipping away at anything that’s metal or concrete, which is just about everything around here,” said Hansen.

“Over 30 percent of our collection system is more than 100 years old,” said Public Works Director Brian Gerving. “So those things add up to mean that there are far more projects that need to be done for our wastewater operations

Residents will weigh in on the proposed timeline and investments during a community meeting on May 16th.

Dr. Gonzalo Cortés, UCLA

As part of UCLA’s Sustainable Los Angeles Grand Challenge, Dr. Gonzalo Cortés visualized the flow of wastewater passing through the various treatment plants in LA County.

According to Dr. Cortés, a researcher at UCLA,  the figures show the different wastewater treatment plant capacities and estimated flows in thousands of acre feet per year. The  data is from LA Sanitation and Los Angeles County Sanitation Districts.

Dr. Cortés is a research scientist at the UCLA Civil and Environmental Engineering Department. A Civil Engineer from Chile, Dr. Cortés got his M.Sc. and Ph.D. at UCLA. His research is focused on developing large-scale high-resolution data assimilation frameworks for water resources estimation and evaluation of climate change impacts in hydrological systems.

He is also a part-time researcher with the California Data Collaborative, a non-profit startup developing digital data infrastructure for water agencies, and a part-time collaborator with the Universidad de Chile Mountain Hydrology group.

A state bill aims to create standards for direct potable reuse by the end of 2021

California’s multiyear drought was officially declared over on April 7, but the Legislature is on the verge of making the state a pioneer in the direct reuse of wastewater for potable consumption.

A bill in the General Assembly would require the state Water Resources Control Board to formulate uniform state standards for potable reuse by Dec. 31, 2021. By June 1, 2018, the board would have to adopt a framework for the regulation of potable reuse projects.

AB 547 is sponsored by Rep. Bill Quirk (D-Hayward), who chairs the Legislature’s Environmental Safety and Toxic Materials Committee. According to a fact sheet prepared by committee staff, the bill has the support of 42 environmental groups, utilities and municipalities. Among them are the U.S. Green Building Council, the Metropolitan Water District of Southern California, and the California Association of Sanitation Agencies.

Eastern Municipal Water District (EMWD) was recognized recently as the Recycled Water Large Agency of the Year by the California Chapter of the WateReuse Association.

The award recognizes EMWD for its comprehensive approach toward investing in its recycled water program to ensure that resources are maximized.

EMWD treats approximately 45 million gallons of wastewater per day at regional water reclamation facilities located in Moreno Valley, Perris, San Jacinto and Temecula. That highly treated wastewater becomes recycled water.

Again in 2016, EMWD achieved 100 percent beneficial reuse of its recycled water supplies, which
were used for irrigation of agriculture, parks, schools, recreational facilities, golf courses, public
landscaping and industrial uses.

Recycled water accounts for 36 percent of EMWD’s water supply portfolio. That figure is among the
highest in the nation.

“We are honored to be selected as the Agency of the Year,” EMWD Board President David Slawson said. “Recycled water is an incredibly valuable asset that allows us to responsibly maximize our resources and reduce dependence on imported water supplies. EMWD is committed to continually investing in our recycled water system for the benefit of all of our customers.”

EMWD has invested nearly $200 million in its recycled water program over the past 20 years. The
investments have resulted in a fully integrated recycled water supply, storage and distribution
system that provides a level of service commensurate with the potable water system.

In 2016, EMWD broke ground on its North Trumble Road Recycled Water Storage Pond, which
increases seasonal storage capacity by 900 acre feet. The facility came online in early 2017 and is the first EMWD project funded in part through Proposition 1 – the Water Bond passed by voters in 2014.

EMWD also recently began work on shallow recovery wells adjacent to its Winchester Ponds. These
75-foot deep wells will recover the recycled water from the ground and pump it back into the storage  ponds for beneficial use. The first phase is anticipated to recover several hundred acre feet of recycled water each year.

Getting rid of waste the clean way: Redwood City company finds a way to turn biosolids into fertilizer with no energy

Source: Daily Journal

Though most don’t think about what happens after a toilet is flushed, Dario Presezzi and his team of five have been hunkered down in trailers at a Redwood City wastewater treatment plant for the last five years laser focused on just that.

Presezzi is the CEO of Bioforcetech, a company working on a system that creates the energy required to turn the human waste collected from wastewater treatment plants into a rich fertilizer.

Starting in April, the small team of Italian natives that make up the Bioforcetech team have the opportunity to make a large dent in a problem most prefer not to think about — what happens to the truckloads of human waste processed at wastewater treatment plants — when they will begin processing half, or 7,000 tons, of the Silicon Valley Clean Water treatment plant’s biosolids, a friendly term the Bioforcetech team uses for human waste.

For Daniel Child, manager of the Silicon Valley Clean Water treatment plant, the Bioforcetech team’s work offers another option for solving a problem with few tried and true solutions. Currently, the biosolids that come through the plant are spread out on land to be dried by the sun for days before they are trucked out of the plant to fertilize farms in Solano County or nearby cities like Sacramento or Modesto.

“Disposal of biosolids is an ongoing challenge in the state of California,” he said. “It’s always good to have more than one option.”

When Presezzi and a few colleagues came to the Silicon Valley Clean Water treatment plant from Italy to explore how their system could work in the United States in 2011, it wasn’t clear the marshy land at the tip of Redwood Shores would become home to their offices.

But ever since 2011, when the plant treating wastewater from Redwood City, San Carlos, Belmont and other jurisdictions voiced support for their team, the six members of the Bioforcetech team have been hard at work refining a college project.

Radhika Fox, CEO of the US Water Alliance and based in San Francisco, will be the facilitator for our AC17 One Water workshop “From Vision to Reality”. But what does “one water” mean? Radhika explains in an op-ed originally published by the US Water Alliance and reprinted with permission.

Building 21st Century Infrastructure for 21st Century Cities

Radhika Fox, CEO US Water Alliance

Radhika Fox, CEO US Water Alliance

The creation of modern water and wastewater systems was one of the most significant public health achievements of the 20th century. Drinking water treatment and systems brought safe, reliable drinking water to homes and businesses. Clean water systems eliminated deadly diseases such as cholera and typhoid and helped extend life expectancy in the U.S. by 30 years. But the systems built 100 year ago were for communities that look completely different than today.

After working around the clock for 70, 80 and even 100 years, water and wastewater infrastructure has been the victim of deferred maintenance for decades, putting our infrastructure and resources at risk.

About 650 water main breaks occur every day – that’s one every 2 minutes—leading to 7 billion gallons of water and $2.6 billion lost through leaky pipes.

In addition to aging infrastructure, water and wastewater systems face additional stresses that builders of the 20th century never expected. They were designed for cities and towns with much smaller populations than they have today. That growth is straining water systems. And in the face of changing climates, intense rainfall, extreme drought, and rising sea levels make it increasingly difficult to maintain safe and reliable operation.

EPA recently published its updated Industrial User Inspection and Sampling Manual for POTWs.

Completed revisions to the 1994 Industrial User Inspection and Sampling Manual for POTWs based on extensive input from experts in the Office of Wastewater Management, and the Office of Science and Technology, and experts in regions, states, and POTWs. The revised Industrial User Inspection and Sampling Manual for POTWs is an inspection support tool provided by EPA for use by field personnel conducting inspections and sampling activities under the Clean Water Act (CWA) National Pretreatment Program. With this revision, inspectors will have access to guidance that reflects changes to the Pretreatment Program and compliance monitoring practices from the past 22 years, such as the 2005 Pretreatment Streamlining Rule. This Manual is not a regulation and, therefore, does not add, eliminate or change any existing regulatory requirements. While EPA has made every effort to ensure the accuracy of the discussion in this guidance, the obligations of the regulated community are determined by statutes, regulations, or other legally binding requirements.

The water sector partnership (which includes WEF and NACWA) has released an update for their Effective Utility Management Primer.

As a water or wastewater utility manager, are these challenges familiar to you?

  • Rising costs
  • Aging infrastructure
  • Increasingly stringent regulatory requirements
  • Population growth
  • A rapidly changing workforce

If so, the 10 Ten Attributes of Effectively Managed Water Sector Utilities and the information in this updated Primer can help you respond to both current and future challenges of the 21st Century. Included in the Primer are five steps to help you begin implementing the Attributes.

The 2017 California Financing Coordinating Committee (CFCC) will be hosting six FREE upcoming funding fairs.  The CFCC was formed in 1998 and is made up of seven funding members: five state and two federal. The CFCC Funding Fairs provide opportunities to learn more about available grant, loan and bond financing options for infrastructure projects. These fairs are directed towards local government representatives, water and irrigation district managers, economic development and engineering professionals, financial advisors, and project consultants.
