Vallecitos Water District Helps San Marcos Coffee Farmer Brew Success

/in , /by

San Diego County agriculture is well-known for citrus and avocados. Kyle Rosa is counting on coffee joining this list.

Rosa, owner of Bluetail Coffee Grove, started growing coffee on a 2.5-acre farm in San Marcos last year. After 15 years in the finance industry, Rosa and his wife moved from San Francisco to start their new venture. The new farmer quickly turned to the Vallecitos Water District for help establishing smart water use and efficient systems to irrigate his six different specific types of coffee.

The Vallecitos Water District offers a free agricultural irrigation audit to ensure its farming customers are using water aligning best with their crop’s specific needs and water-efficiency standards.

“No one has ever done this in the continental United States,” said Rosa. “To be able to be a pioneer and work on something that has never been done and to learn from mistakes is exciting.”

Lance Andersen, agricultural program manager from Mission Resource Conservation District, performed the audit. MRCD provides free agricultural evaluations to farmers and growers through a partnership with Vallecitos and the San Diego County Water Authority. The agricultural audit examined 2,000 of the Bluetail Coffee Groves trees and 4,000 emitters to see how much water is currently used.

Auditors study how evenly water is flowing across the planting area, so growers can make informed decisions on irrigation scheduling and water management. Post-audit, farmers receive a Google image to assist in the best placement for soil moisture sensor stations to monitor irrigation in real time.

“Lance has been able to give us some pointers as he walked through the farm,” said Rosa. “We have some areas of improvement to add swales to retain water when it rains on our slopes and to prevent soil erosion.”

MRCD also provided information about financial assistance available for the installation of the soil moisture sensors.

Vallecitos Water District assisted Rosa in securing an agricultural rate for his irrigation. He worked with Chris Robbins, Vallecitos Water District supervisor of public information/conservation to start the process.

“He could not have made it any easier for me,” said Rosa.

Bluetail Coffee Grove is an organic farm. Rosa’s farm is undergoing the organic certification process, which takes three years.

Coffee farm plans for eco-tourism

Rosa has ambitious plans to put San Marcos on the coffee map.

“Coffee has a similarity to wine, where the method of creating a cup of coffee is so diverse and so labor-intensive,” explained Rosa. “When you finally get a cup of coffee, everybody has different tastes. Being able to produce those different tastes for a variety of people while having complex notes within our coffee is really what we are striving for.”

Rosa says he hopes his initial business model will work, allowing him to open his farm to eco-tourism.

“The goal is to expand the coffee to have an eco-tourism set up at the farm, where we can roast and try coffee right here and pull the cherries right off the tree and taste the coffee right here for yourself right in beautiful San Marcos, California.”

Before then, Rosa will open a retail store, Breakers Coffee + Wine in the Del Mar Heights area, expected in Spring 2021.

Solar Project Saves Energy, Costs for Vallecitos Water District

The Vallecitos Water District is pursuing greater use of renewable resources, increasing capacity to the electrical grid, and reducing long term operational costs with an innovative solar power project.

The west solar array is installed on top of the Vallecitos Water District’s 33-million gallon reservoir with 2,300 solar modules and eight 80 kw inverters. The east array is located on top of the 40-million gallon reservoir with 2,900 modules with ten 80 kw inverters. Photo: Vallecitos Water District

In 2017, the Vallecitos Water District Board of Directors agreed to pursue development of districtwide renewable power sources using existing open space to benefit the District and its ratepayers.  The District worked with solar consultants Terra Verde Renewable Partners to evaluate and study the feasibility of three solar port locations. Two projects are now moving forward; two arrays at the pair of Vallecitos owned reservoirs in Twin Oaks, and an array at the (sewer) Lift Station #1, located on San Marcos Boulevard.

The projects are structured under a Power Purchase Agreement. A solar provider designs, builds, and maintains systems for 25 years. In turn, the District receives a reduced electricity rate from SDG&E over the 25-year term at the District’s 13 highest use meters. The District will become owners of the solar system after the 25-year maintenance term expires. No capital investment is required from the District.

“The project is a great benefit to Vallecitos customers,” said Ryan Morgan, Capital Facilities Senior Engineer. “Through our export of power into the electrical grid, we receive bill credits on these power exchanges. The District benefits directly through reduced power costs, and that cost savings is passed down to the customer ultimately in reduced water and sewer rates.”

Multiple stakeholders working together

Vallecitos Water District provides the project sites, working with SDG&E, the solar provider team, the District’s contractors, and the solar maintenance operator. The District’s water professionals work with solar power experts to guide the project through planning, design, and construction as a team.

Over the 25-year term, the District will benefit from a reduced electrical rate of 7.79 cents per kilowatt-hour (kWh) at its 13 highest use meters. It will also receive a rebate or credit on its export of power to the electrical grid. Savings to the District over 25 years are estimated at $8.3 million, which ultimately results in reduced water and sewer rates for customers. District staff locked in the maximum federal rebate by launching the project in 2019 and meeting a narrow window for grant funding.

The west solar array is installed on top of the District’s 33-million gallon reservoir with 2,300 solar modules and eight 80 kW inverters. The east array is located on top of the 40-million gallon reservoir with 2,900 modules with ten 80 kW inverters. The total production is roughly 3.6 MWh annually, enough to power 340 homes.

Local power conservation remains vital

While the solar power project cannot prevent the potential for power outages due to rolling blackouts, the project helps to add capacity to the power grid when it is needed.

“The District wants to publicly thank Terre Verde Renewable Partners, Holt Renewables, and Kenyon Energy for their valuable roles in the success of this project,” said Morgan.  “We also want to acknowledge the above and beyond effort of the District’s inspections team.”

The Twin Oaks Reservoir dual array is expected to be completed in November 2020. The Lift Station #1 site is expected to be completed in February of 2021.

Mahr Reservoir was completed in 1981. Originally called La Costa Storage No. 1 Dam and Reservoir, it was renamed after the district’s original founder 35-year board member Stanley A. Mahr. It stores up to 54 million gallons of reclaimed water to be used later for irrigation. The district has contracts with the City of Carlsbad and Olivenhain Municipal Water District to provide water as needed, as much as five million gallons of recycled water daily.

Because the reservoir’s location receives intense sunlight with little rain, algal blooms can occur in the nutrient-rich recycled water. The most common method of treating algal blooms is with harmful chemicals. They are costly and labor-intensive.

The district instead uses technology developed by the international company LG Sonic, which provides a complete overview of the water quality allowing swift identification and treatment of algal blooms.

New ultrasound technology reduces cost and environmental harm

NOTE: Portions of this video were filmed in 2019, prior to the COVID-19 pandemic and any mandatory face covering requirements.

Every 10 minutes, an MPC Buoy in the Mahr Reservoir measures and monitors green and blue-green algae population, pH, turbidity, dissolved oxygen, and water temperature. The data is collected in real time and uploaded to a web-based software. The software uses the data to predict algal blooms three to ten days in advance.

The LG Sonic buoy can create a sound barrier in the top water layer, which affects the buoyancy of the algae, preventing it from rising up where it can absorb sunlight for photosynthesis to grow. Without sunlight and nutrients, algae cells sink to deeper water where they degrade due to natural bacteria and do not release toxins into the water.

With overall algae levels reduced by this technology, the need for chemical treatment is also reduced, allowing the Vallecitos Water District to provide high quality reclaimed water to its customers.

LG Sonic’s specific low power ultrasonic transmitters emit signals which are not harmful to people, fish, plants or other wildlife.

After the initial installation, an unusual incident occurred. Electrical cords providing power to the reservoir’s water pumps became wrapped around the inlet/outlet pipes located underwater. Mahr’s algae meter needs water flow from the reservoir to be able to read the algae level.

Maintenance staff couldn’t untangle the power cords from above the water. Specialty divers were called in to address the problem. Vallecitos Pump and Motor Technician Dale Austin also had divers inspect pneumatic (air) and hydraulic (oil) lines to the motors (actuators) that open and close the inlet and outlet valves for leaks. Divers successfully untangled the electrical cords and they were secured to prevent future problems. Divers found no leaks on the lines.
