Panelists Set to Explain Laws Limiting Water Consumption

Panelists from several water districts will give updates on new laws affecting water consumption in California during an American Liberty Forum of Ramona event set for Saturday, June 27.

The free forum on Water Regulations Today and Tomorrow will be held at Ramona Mainstage, 626 Main St. Doors open at 11 a.m. and a video program starts at 11:30 a.m.

The focus will be on Senate Bill 606 and Assembly Bill 1668.

SB 606 is in response to mandates that California achieve a 20 percent reduction in urban per capita water use by Dec. 31, 2020. Existing law requires each urban retail water supplier to develop urban water use targets and an interim urban water use target.

AB 1668 would require the state Water Resources Control Board to adopt long-term standards for the efficient use of water and would establish specified standards for per capita daily indoor residential water use.

Vallecitos Water District Crews Rehab Manhole, Protecting Environment

Vallecitos Water District crews sprang into action to repair and rehabilitate a manhole in danger of failing, successfully preventing a spill, which could have resulted in significant environmental damage.

Located just off Palomar Airport Road in a shared 30-foot easement with the Buena Sanitation District in Carlsbad, the manhole is part of a 30-inch outfall providing a main sewage drain for the City of San Marcos. The line feeds directly into the Encinas Wastewater Treatment plant a half-mile from the project site.

Vallecitos Water District Crews Rehab Manhole, Protecting Environment  

Vallecitos Water District crews sprang into action to repair and rehabilitate a manhole in danger of failing, successfully preventing a spill, which could have resulted in significant environmental damage.

Located just off Palomar Airport Road in a shared 30-foot easement with the Buena Sanitation District in Carlsbad, the manhole is part of a 30-inch outfall providing a main sewage drain for the City of San Marcos. The line feeds directly into the Encina Wastewater Treatment plant a half-mile from the project site.

Originally constructed in the 1980s, turbulence generated by a hard right-turn along the sewer easement creates hydrogen sulfide gases. These gases corrode concrete and weakened the manhole over the years. Flooding also occurs in the area and allows rainfall to infiltrate the manhole.

Preventing harm to sensitive habitat areas

Vallecitos Water District staff became concerned the structure could fail. The result would be a major sewage spill affecting the nearby Encinas Creek Habitat Conservation Area, ultimately spilling into the Pacific Ocean a mile downstream. The Habitat Conservation Area is owned by the Center for Natural Lands Management, which supports its management through an endowment.

The Encinas Creek HCA is also part of the City of Carlsbad’s habitat management preserve. It includes riparian habitat and is known to be home to state and federally protected species. The Center for Natural Lands Management works to protect the property from trespassing, nonnative invasive plant and animal species, and other issues.

The District determined emergency repairs were required. Although the Vallecitos Water District has proper easement rights to access, operate, and maintain the pipeline, the agency must avoid any impact to the existing habitat while repairing the manhole. This required some creativity by the work crews.

The District kept all construction activities within its existing easement to avoid any impacts to existing riparian vegetation. Crews constructed a temporary bridge over an existing stream obstructing access to the manhole. The bridge installation was designed to be temporary, and not affect the existing stream with footings or other supports. Constructing the bridge for access turned out to be the most complex part of the repair project.

District crews working with a contractor team took advantage of the lower sewage flow during the early morning hours, starting work at 3 a.m. to get as low into the waterline as possible. Repairs like this take advantage of the low flows to keep critically important sewer systems in operation.

Instead of replacing the manhole, the District used a polymer concrete replacement product to build a new manhole within the old manhole. As a result, no excavation was needed. Unlike regular concrete, the new material is corrosion-proof and should provide District customers in San Marcos with many years of reliable service while protecting the environment.

Vallecitos Water District Employs Technology to Decrease TSS, pH and Algal Blooms

Vallecitos Water District provides 5.25 million gallons of recycled water for irrigation every day. To fulfill the demands of modern irrigation systems, it is important to maintain low TSS levels. This is a challenge during the warm months in California, as algae that occur with raising temperatures, increase the level of TSS and clog the filters that are meant to remove TSS before the distribution of water to the irrigation systems.

Vallecitos Water District is known for its’ sustainable and innovative focus when it comes to water and wastewater treatment.

Water Utility Hero of the Week: Dale Austin

Job/Agency: Vallecitos Water District Senior Pump & Motor Tech

How did you become interested in working in the water industry?

I had friends and a neighbor that worked for different agencies and different jobs. They all talked highly of their agencies and the jobs they did. I wasn’t sure where I would fit into the industry so I took classes in Water Distribution, Water Treatment, and Wastewater Treatment. I learned so much in those classes. I applied and got my first job in Water Distribution where I could apply my skills as a Certified Pipe Line Welder and Machinist, but my passion has always been in mechanical, so I transferred to a treatment plant which led me to my current job with Vallecitos.

How has your job changed during the pandemic?

I pride myself in having my equipment 100% available, so with the pandemic Vallecitos is doing a rotating schedule to help with distancing and safeguarding the crews. Staying in contact with the crew on duty via email and phone. Prioritizing work loads and talking to vendors. I don’t personally like to carry my phone when not at work but with the pandemic it is a very important tool to stay in contact with everyone.

How are you keeping safe?

By following guidelines from the CDC, maintaining social distancing, and following good hygiene.

What are you most looking forward to after the crisis ends?

Sitting down at a restaurant for dinner and going to the movies with my wife.

Tank Cleaning Program Helps Vallecitos Water District Maintain Safe Water Supply

Seventeen above ground steel tanks and two underground concrete reservoirs play a vital role in the Vallecitos Water District’s mission to provide clean, safe, and reliable water to its 105,000 district residents. Maintenance and cleaning of the tanks and reservoirs is a critically important process.

Without regular washouts, tanks can accumulate large amounts of sediment, prohibiting proper inspections.

California State Water Resources Control Board Division of Drinking Water standards require that tanks must be cleaned every three years.

Vallecitos Water Operations’ team cleans up to six tanks annually. Regulations call for the district’s six certified water operators to empty and enter the tanks for inspection to ensure there is no structural damage or other concerns prior to the tank washout to ensure continued operation of the water distribution system. Vallecitos adheres to a strict inspection schedule as part of its preventative maintenance program.

“We want customers to know we’re being diligent protecting the water infrastructure,” said Richie Arballo, senior water systems operator. “If we find an issue where a tank needs to be refurbished, we want to correct it as soon as possible, before it becomes an emergency.”

Vallecitos staff schedules tank cleaning during winter months when water demand decreases. Initial steps include how to best reroute water delivery while tanks are taken out of service for cleaning. After the tank is drained, water operations staff enter the tank for a thorough inspection, followed by cleaning and disinfection.

When the process is complete, staff refills the tank near its spill level and allows the water to stand for 24 hours before conducting water quality analysis. Once lab results are reported and submitted to the state’s Division of Drinking Water, it will determine when the tank can be placed back in service.

Tank cleaning began in March but was put on hold due recent rains and the coronavirus pandemic, with the the need for physical distancing. See the cleaning process depicted in this video.

Safety and environmental stewardship

During draining, water is discharged to a storm drain or dirt area where it is absorbed back into the ground naturally. Once the tank is removed from service, it is isolated from the water distribution system. Valves are secured and double-checked to be sure they are completely closed. Staff members wear respiratory protection due to chemicals used during the disinfection of the tank interior.

Cleaning and disinfecting the large reservoirs requires teamwork. The Water Operations team calls on staff from the Vallecitos Water District Collections and Construction departments to augment and support its personnel.

“When we all work together it really shows how much of a team we are here at the District,” said Shawn Askine, water systems supervisor. “We are very fortunate at Vallecitos to have employees willing to come out and help us clean the tanks properly and effectively, so we are utilizing customer dollars as efficiently as possible.”

Due to the amount of equipment and coordination required, the Vallecitos Water District created a customized trailer specifically for conducting tank cleaning. The small investment allows all required equipment to be stored on the trailer, ready to go on the day of the scheduled cleaning. The trailer and equipment significantly streamline the process and ensures all parts, fittings, and washout equipment are available to get the job done effectively.

Customer Thanks Vallecitos Water District Employees for Their Efforts

Most Americans take a safe and reliable water supply for granted. Dedicated water and wastewater professionals, including Vallecitos Water District employees, work to provide a secure, plentiful supply of drinking water.

Vallecitos Water District customer Manisha Bambhania has a deeper appreciation. A native of India, Bambhania grew up in a home where running water was only available three hours per day, and sometimes much less.

Bambhania frequently posted favorable comments on Vallecitos Water District Facebook posts.

“She would commonly write words like, ‘We all need to conserve, regardless of the drought,’ or ‘Thank you for all you do. We are so grateful for the services you are providing,’” said Public Information Representative Lisa Urabe.

“After more than a year of continued praise from Manisha, the public information staff reached out to her to thank her in person for her comments,” said Urabe. “We met at her house where she proceeded to tell us her story of growing up in India. Even though she lived in an upper middle-class neighborhood, water scarcity and lack of reliable water and wastewater infrastructure was a very real part of daily living.”

Vallecitos staff created a video to share Bambhania’s story about the work of Vallecitos Water District employees.

Vallecitos Water District employees ‘inspired’

Vallecitos employees viewed the video at a recent all-staff meeting. One of those employees is Dennis Richardson, who has worked for the agency the past 13 years.

“I thought it was incredible for a customer to actually thank the employees for the jobs that they do, and also to give us her past life experience of living in India and the importance of the water to the community,” said Richardson. “I was really inspired by her video.”

Other staff were also pleased at the positive remarks for their work.

“We all enjoy our jobs, and take great pride in what we do in serving the public,” said Shawn Askine, a water systems supervisor. “We’re happy citizens recognize the hard work we do providing clean reliable water to your tap everyday.”

The original video featuring Manisha Bambhania has also won statewide recognition from the California Water Environment Association Film Festival.
