Oceanside Breaks Ground for Recycling Plant That Will Provide 32% of City’s Water

Oceanside officially broke ground Wednesday on an innovative water recycling plant that will provide 32% of the city’s water supply in future years.

Although San Diego is working on a similar and larger project, Pure Water Oceanside will be the first operating advanced purification facility in the county.

The plan will use microfiltration, reverse osmosis and ultraviolet light to purify wastewater from the San Luis Rey Water Reclamation Facility, reducing the city’s reliance on water imported from the Colorado River and Sacramento Bay Delta.

New Water Recycling Projects Will Help Battle Central Coast’s Seawater Invasion

For decades, California’s coastal aquifers have been plagued by invading seawater, turning pristine wells into salty ruins. But the state’s coastal water agencies now plan to get more aggressive in holding back the invasion by injecting millions of gallons of treated sewage and other purified wastewater deep underground. The additional groundwater will both enhance potable water supplies and help prevent saltwater from seeping further into coastal California’s massive subterranean reservoirs. A decade ago, Orange County was the first in California to successfully employ this tactic — mocked by critics as a “toilet to tap” solution.

Vallecitos Water District Training Preps Firefighters for Wastewater Plant Emergencies

North San Diego County fire agencies teamed up in November with the Vallecitos Water District for confined space training drills. The drills, held over a two-week period, prepare firefighting professionals to respond to emergencies in facilities such as wastewater treatment plants and maintain their confined space certification.

The recent training took place at the Vallecitos Water District’s Meadowlark Reclamation Facility. Firefighters saw how the wastewater plant operates while getting a walk through of the facility. Fire personnel worked with Vallecitos staff and both groups benefited from the opportunity to understand each other’s equipment and protocols.

“The confined space training with the fire agencies has helped prepare us for future scenarios that could happen at the plant,” said Dawn McDougle, wastewater plant supervisor.

The Meadowlark facility was chosen because it provided both vertical and horizontal confined spaces for training drills. McDougle suggested the facility storm wet well be used for the confined space exercise since it is relatively environmentally clean.

Collaboration results in more efficient response to emergencies

Eight different fire agencies trained during morning or afternoon sessions, breaking up groups for various skill set station drills. Stations included an “Arizona vortex,” a new piece of equipment fire agencies use for rescues; a review of confined space rescue equipment; and training in confined space permit requirements. Confined space permits are required by OSHA before making any kind of confined space entry or rescue.

Meadowlark staff reviewed the conditions and possible actions within filter station space with fire crews. Staff also explained decision-making for confined space entry, and conditions they might encounter, such as chemical exposure, and lock-out/tag-out requirements.

The training wrapped up with an all-hands mock confined space drill scenario at the Meadowlark storm wet well. Participants were required to respond to a simulated mechanical failure with a station pump, leaving Vallecitos staff “trapped” in a hole. First responders needed to “rescue” Vallecitos staff. Fire department personnel used the vortex system to rescue personnel trapped in the stormwater wet well. As part of the rescue scenario, fire teams incorporated Vallecitos staff involvement in the rescue mission.

Vallecitos wastewater collection crews also completed the confined space training with the firefighters.

Fire agencies were impressed with the staff and their operation of the Meadowlark Reclamation Facility. As a result of training, fire agencies can now respond more efficiently and with confidence.

“We appreciate the collaboration with fire agencies and the time they took to explain their procedures to Vallecitos District staff,” said McDougle. “We look forward to future training with the fire agencies.” 

Firefighting agencies participating in the training included crews from the cities of Carlsbad, San Marcos, Del Mar, Vista, Escondido, Oceanside, Encinitas, Solana Beach, Rancho Santa Fe, Valley Center, and crews from North County Fire (Fallbrook), San Pasqual and Rincon.

San Francisco Recycled Water Program Pushing Wastewater Towards Drinkability

By design, the San Francisco Public Utilities Building is exceedingly green. It opened in 2012 and for years the building has been recycling its wastewater for things like flushing the toilets. Now, that water can be consumed.

“Everything that’s connected in this room to the transparent pipe is part of our research project,” explains Manisha Kothari, Project Manager for the SFPUC.

Down in the bowels of this building that houses some 900 employees, you will find the equipment that treats all of their wastewater.

 

Yorkshire Water Launches World’s First Poo-Powered Pub

In what will be the first time a public space has been powered by electricity made from poo, The Number Two Tavern is launching for a limited time in The Light, Leeds from 7th until 9th November.

The company is holding its first ever carbon week to spread the word and share knowledge about how we can all reduce our carbon footprint.

The power for The Number Two Tavern is coming from a ground-breaking process, called “anaerobic digestion,” which converts waste into biogas that can be used to generate heat and electricity. Yorkshire Water has charged a Hybrid Power battery with the poo-power, which is being created at Yorkshire Water’s Knostrop Recycling Centre.

Opinion: We Must Press California, Federal Officials to Clean Up Toxic Rivers

Contamination of soil and groundwater takes a huge toll on California’s environment.

In 2017, the amount of untreated sewage and industrial waste dumped into Southern California rivers was equal to at least 500 Olympic-sized swimming pools. More than 100 million gallons of untreated sewage were dumped into the Tijuana River near Imperial Beach in September 2019.

The problem is getting worse.

Ukiah’s Wastewater No Longer Being Wasted

The city of Ukiah made its first delivery of recycled water through its extensive Purple Pipe system this week, putting about 2 million gallons of water reclaimed from local sinks, showers and toilets into an irrigation pond just south of the Ukiah Valley Wastewater Treatment Plant.

A Look Inside Ventura’s Wastewater Operations. What’s The Future of its Estuary Discharge?

There’s a lot of confusion and concern about what will happen once the city of Ventura no longer discharges millions of gallons of water into the Santa Clara River Estuary.

There are questions over what will happen to the birds, fish, turtles, ducks and other critters once their environment dramatically changes.

Progress Made on Calexico Sewer and Water Plant Upgrades

Although preliminary work and the replacement of aging water lines are already underway, the bulk of about $40 million in upgrades to Calexico’s water and wastewater treatment plants won’t start until 2020, a city official explained. The process to reach the point of construction is a lengthy one, but the city is making steady progress, Assistant City Manager Miguel Figueroa said.

How PFAS Poses An Emerging Problem For Wastewater

The intrusion of PFAS into source water supplies has grabbed the regulatory spotlight. As more scientists and health professionals raise concerns about the compounds — technically known as per- and polyfluoroalkyl substances — federal and state environmental agencies are under increasing pressure to impose limits for public protection. Now, it seems that municipalities have another looming headache as PFAS is finding its way into wastewater.
