The Grand Bargain, a three way trade in water and economy for San Diego County

November 14, 2014

Recycled wastewater pumped storage power plant planning

 

 

  • Allocate funding away from proposed Bay Delta projects(the tunnel project) and redirect to total waste water recycling
  • Build nighttime recycled waste water storage facilities at elevations above San Vicente reservoir incorporation recycled water into a pump storage power plant.
  • Recover recycled water costs to ratepayers by selling power!
  • The remainder of recycled water to direct reuse as potable water. This is the capital expensive version of this idea see page 6 for a capital light version!
  • Use San Diego manufactured shipping(NASSCO) To transport Alaska water for 40 years to San Diego pumped storage power project

 

The 2012 San Diego water reuse study did not consider pumped storage energy sales

The 2012 san Diego water reuse study did not consider building or own transport fleet to import water

 

240 million gallons per day recycled water should be our goal not 80 million per day

Enough to no longer need the EPA waiver for Point Loma

Enough for pumped storage to El capstan and San Vicenti at 80 million per day each!

The proposed El Capitan pumped storage project would be more expensive but again power ratepayers would pay a part of the costs along with water ratepayers!

Recycled water pump storage power plant

 

Needs 80 million gallon per day storage facility at an elevation above san Vicenti reservoir

Receives water overnight and releases it for morning hour power demand

Needs a right sized pipe to move 80 million gallons over night in less than a 10 hour period

Needs power turbines between storage and the reservoir and between the reservoir  and lower elevations

180 MGD split between San Vicente and El Capitan for pumped storage

In the event direct potable use is allowed?

Proceed with pumped storage if;

Power sells make it feasible divert Point Loma plus stored storm water*** to a pumped storage project

Storm water storage would need to handle many days at 320 MGD X 3 days = 660 MG

Gradually empty storm water storage into the water recycling system

Winter months total drain water recycling allows for additional reservoir storage of imported water and storm water storage  is located close to the proposed pumped storage projects

 

 

 

 

 

Run imported water to a pumped storage power plant?

 

This would be a San Diego aqueduct pumped storage project

Decentralized distributed recycled water pumped storage power plants

These would be direct recycled  potable water and recycled storm water that is stored overnight as part of pumped storage power plant.This replaces the proposed San Vicenti and El Capitan recycled water pumped power plants.An example would be the North plant recycled water and recycled stormwater would be stored overnight atop Soledad mountain in La Jolla and would produce power the next day at peak periods.Another example would be Sweetwater reservoir and El Cajon mountain pumped storage combined with the south bay recycled water plant.

Alaskan LGN  & water transported by ship, powers waste water pumped storage

Ships built in San Diego By NASSCO, As many as 5 ships at $100 Million apiece

$500 Million

10 ships at $75 Million per unit $750 Million delivered over 20 years and amortized over 40 years per ship

$20 Million per year plus operations and water purchase costs

15 ships at $1.25 billion should deliver amortization costs and operations costs of under $100 Million per year for 40 years

So the San Diego desalination plant at 50 MGD equals to 154 acre feet per day while one ship with 200,000 tons of water equals out to 160 acre feet.The San Diego desalination plant at 50 MGD equals 10% of the region’s water supply.Water transported by ship would be the worlds most expensive so the goal should be to have this supply at less than 10% of water delivered so as to reduce the burden on San Diego water rate payers while at the same time stimulating San Diego ship building with mass-produced ships.

18 ships at 200,000 tons of water each day would be about 11% of San Diego’s water supply so lets half that amount to 9 ships arriving in port every other day and Sitka Alaska is 7 days travel time to San Diego.9 ships built in San Diego’s NASSCO ship yard represents a bulk buy so we should receive a discount that represents under $100 million per ship so 9 x $80 Million is $710 Million with a ship delivered every 2 years this is a build out over 18 years and each ship amortized over 40 years.this would be a 60 year payout period.The ships would cost $45 Million per year plus operations costs after the 18 year build out period ended

Dual manifested LGN/Water carrier ships?

This would open the doors to a lot of possibilities; such ships could transfer Alaskan North slope LGN without a $8 Billion pipeline.The ships would also be built in San Diego to deliver LGN to San Diego.If the ships could be designed to carry both water and LGN on separate voyages we could amortize costs between San Diego water and power ratepayers and inject billions more into a San Diego mass produced shipbuilding industry

The north slope is 15 days by sea to San Diego so a ship arriving every day would be 30 ships at sea at any given time, most likely we do not need a ship a day.A shipment every other day would be a fleet of 15 ships but let’s have that again since PG&E already has an existing long-term supplier.8 ships delivered from the NASSCO ship yard further increases the rate of launch to perhaps 1 per year when combined with water delivery needs

LGN would be delivered to San Diego Gas & Electric and Southern California Gas company both SEMPRA company operating units,if the Southern California gas company unit has LGN delivered to it then this might be the bases for a fleet of larger than 8 ships. Ratepayers of Southern California Gas company would want to know that we would do ship repairs and refurbishing in the rate payers territory

 

 

The first LGN/water carrier ship shall be named the Robert Estavillo  my foster father and WW-2 veteran  who worked at NASSCO for 30 years in San Diego, the second LGN/water ship shall be named the Patrick B Miller my step father who also a WW-2 veteran worked in San Diego for 30 years for Teledyne Ryan The third LGN/water carrier ship shall be named the Don W rappolee also a WW-2 veteran who served as a medical corpsman at the Balboa park hospital
