Olivenhain Municipal Water District’s Recycled Water Pipeline Extension 153A was recognized September 10 as a 2020 Project of the Year by the San Diego and Imperial County Chapter of the American Public Works Association at its virtual awards event. The pipeline extension connected the Surf Cup Sports youth soccer fields in San Diego to OMWD’s recycled water distribution system. By allowing Surf Cup to convert the irrigation of 55 acres of grass fields to recycled water, OMWD has reduced potable water demands for irrigation by up to 100 million gallons per year.

Encinitas, Calif. — The California Department of Water Resources approved a grant package that will provide $2.8 million in state grant funding to three North County water and wastewater agencies to expand and upgrade recycled water infrastructure.

The Rancho Santa Fe Association board unanimously supported nominating Frank Creede to fill the vacancy on the Santa Fe Irrigation District board, representing Division 1. As the Santa Fe Irrigation (SFID) board failed to appoint a new director to fill the seat vacated by Ken Dunford last month, the appointment now moves on to the San Diego County Board of Supervisors to decide.

The Santa Fe Irrigation District is seeking a new local representation after Division 1 Director Kenneth Dunford submitted his resignation. Dunford sent notice to the district and his fellow board members that he had made a commitment to move to Carlsbad; his last day of service was March 31.
The vacancy will be filled by the appointment process and the new board director will serve until the November 2020 election.

It’s the only one of its kind in Southern California and no one will see it again for years.
“It’s a giant upside-down cone with some pipes,” said Jeff Pasek. “It’s a strange looking device.”
It’s a strange looking device called a Speece Cone that’s expected to improve the water quality at Hodges Reservoir near Escondido.
“It’s not going to be seen again for a number of years because it’s 70 feet deep in the reservoir,” said Pasek, a Project Officer with the City of San Diego’s Public Utilities Department.
The $3.4 million project will constantly inject oxygen into the reservoir which will reduce the nutrients that algae feed on, Pasek said.

The city of San Diego’s Hodges Reservoir will officially reopen to the public three days a week beginning on Wednesday, Feb. 5, allowing access for a variety of activities, including boating, fishing, hiking and picnicking. Hodges is normally closed November through January.
Hodges will be open Wednesdays, Saturdays, and Sundays from sunrise to sunset. It will also be open on Memorial Day, Independence Day and Labor Day holidays.

The Santa Fe Irrigation District approved three percent water rate increases for the next three years at a Jan. 16 hearing. The first bills will go out to customers on April 1 using a new five-tier residential rate structure that differentiates between meter sizes in higher tiers.
The rate increases aim to help meet the district’s objectives to ensure equity across customer classes, encourage conservation and maintain financial stability as it faces challenges such as the rising costs of imported water.
Encinitas, CA—To encourage water conservation and reduce runoff that can carry pollutants into local waterways and beaches, Olivenhain Municipal Water District has partnered with San Dieguito Water District and Santa Fe Irrigation District to offer discounted rain barrels to area residents.
The City of San Diego’s Public Utilities Department last week took a major step toward completing an innovative project to improve water quality in Lake Hodges. A newly installed oxygenation system, designed by city engineers, will introduce highly oxygenated water to the bottom of the reservoir to reduce the accumulation of excess nutrients and harmful algae growth.
The increase of nutrients and algae in the water has been caused by human activities in the watershed upstream of the reservoir, including residential and commercial development, agriculture, and land clearing. Degraded water quality can restrict the ability to move water in and out of the reservoir.
“The ‘Speece cone’ is a fairly unique method for adding oxygen to a reservoir – there are only a few of them in the world,” said Jeff Pasek, project manager at the City of San Diego Public Utilities Department. “This project derived from a planning study that was done about five years ago, which identified oxygenation using the ‘Speece cone’ as being the most cost-effective way of addressing the water quality problems in Hodges.”
Last week, the 130,000 pound cone – named after the inventor of the technology, Richard Speece – was lowered eighty feet to the bottom of the reservoir.
Streamlined operation for maximum efficiency
The precisely coordinated operation involved lifting the 20-foot tall stainless steel cone with a large crane, while simultaneously driving a barge out from underneath. Once the cone was lowered into the water, divers headed to the bottom of the reservoir to unhook the cone from the crane, check to make sure it settled in the correct spot, and fasten it down.
In order to build a solid foundation underwater, crews excavated approximately 11 feet of silt from the bottom of the reservoir and constructed a concrete base. Before submerging the cone, crews installed and tested a pump that will move water through the cone. A large diffuser pipe was then lowered and connected to the cone by divers. The diffuser will distribute the oxygen-rich water throughout the reservoir.
Now underwater, the cone will distribute oxygen-rich water throughout the reservoir to reduce the accumulation of excess nutrients and prevent harmful algae growth. Photo: Water Authority
Local and regional benefits at Hodges Reservoir
Hodges Reservoir is owned and operated by the City of San Diego, and it serves the San Dieguito Water District and the Santa Fe Irrigation District. It is connected to the San Diego County Water Authority’s Olivenhain Reservoir as part of the Emergency & Carryover Storage Project, which is designed to ensure regional water reliability in case of emergencies or if the region is cut off from imported water supplies.
“There are multiple benefits to this project – first and foremost being the water quality improvements for Hodges Reservoir,” said Goldamer Herbon, a senior water resources specialist at the Water Authority. “Ancillary benefits include operational flexibility for regional supply benefits and preventing the accumulation of mercury, which can be harmful to people and wildlife that eat fish from the reservoir.”
The California State Department of Water Resources awarded the City of San Diego a $3.4 million grant funded by the San Diego Integrated Regional Water Management program to complete the oxygenation project, which began in February 2019.
