The Crisis

Inaction Since 2000

When San Diego purchased Colorado River water from Imperial County in the QSA, the state agreed to offset the decline of the Salton which would result.

Fast forward 20 years, no water importation proposal was selected, and the state of California opened up the Request for Proposal (RFP) process a second time.

Stale Ideas - Overland Canals

Every proposal to date had the same theme - transport water from Mexico overland via canals, filling Laguna Salada to reduce the distance.
They all had the same issue - getting Mexico to agree

Our Proposal - Tunnel Aqueducts

We found an approach no one else had - a tunnel from the Pacific.
An entirely domestic solution, avoiding land rights battles & terrain by going underneath it all.
And best of all - we let gravity do the work!

Below, we walk you through the key breakthroughs that made this solution possible.


The Technology - Tunnels

Terrain Agnostic

Going under obstacles, tunnels unlock entirely new routes under mountains, cities and any other surface obstruction.
We leverage this freedom to take previously impassable approaches from the Pacific to the Salton, and Mediterranean to the Dead Sea for entirely domestic solutions

No Land Acquisitions

Going far below the ground, obtaining permission becomes an order of magnitude easier, and enables direct routes ideal for low cost water conveyance.

We avoid the use of Eminent Domain,
and the quagmire of massive land acquisition.

Low Impact

By travelling in a direct line, we eliminate the need for expensive pumping for water import - and dramatically reduced cost for brine removal since we can cut through mountains rather than pumping all the way over them.
With the Salton and Dead Seas being below sea level, we let gravity move the water!

An Old Technology...

The longest tunnel in the world, the Delaware Aqueduct was built from 1939-1945 and to this day provides NYC with 50% of its drinkable water supply!
It works so well, most have never heard of it.

Length - 85 miles (136.7km)
- 13.5ft (4.1m)
Max Depth - 2,500ft (762m)

With Modern Applications

The Bellwood Quarry Tunnel completed in 2020 was built to transport water to fill an aqueduct for emergency water supplies for Atlanta - demonstrating the relevance of tunnels in the modern context

Length - 5 miles (8km)
Diameter - 12ft (3.6m)
Max depth - 300ft (91m)


The Routes

Amazingly, the Salton and Dead Seas, as well as Lake Eyre and the Qattara are all significantly below sea level - offering a gradient sufficient to move water entirely by gravity & pressure alone, no pumping required!

Whereas all prior proposals required incredibly costly pumping costs, racking up millions to billions of dollars annually in energy costs,
tunnels enable free flowing water to follow a direct gradient down to the Salton, Dead Sea, Qattara and Lake Eyre depressions.

The Dead Sea (-1412ft)
Lake Eyre (-50ft)
Qattara Depression (-482ft)

Removing the Brine

An outflow for the salt

Offering what no other proposal has, with straight tunnels and steady gradients, we realized we could not only import water, but remove the brine to circulate the seas

At the Salton Sea, this would require only 1/3 the pumping capacity of the Banks Pumping Station feeding the California Aqueduct - at an estimated cost of $15M per year in energy.

And the Seas Self-Heal

As the salinity is gradually restored to near ocean water levels, fish can be restocked triggering a trophic cascade as nature returns to the formerly dead seas.

The system capacity can be expanded as necessary to reach the desired steady state salinity levels - the more throughput, the closer to ocean levels the seas reach.
