And if the water's still not clean enough to drink after it's been through this natural treatment process, the city can treat it again when they pump if back out of the groundwater aquifers before they deliver it to people to drink.
The second tap that we need to open up to solve our urban water problem will flow with the wastewater that comes out of our sewage treatment plants.
Now, many of you are probably familiar with the concept of recycled water.
You've probably seen signs like this that tell you that the shrubbery and the highway median and the local golf course is being watered with water that used to be in a sewage treatment plant.
Because once we build the first few water recycling systems close to the sewage treatment plant, we have to build longer and longer pipe networks to get that water to where it needs to go.
What we're finding is that a much more cost-effective and practical way of recycling wastewater is to turn treated wastewater into drinking water through a two-step process.
In the first step in this process we pressurize the water and pass it through a reverse osmosis membrane: a thin, permeable plastic membrane that allows water molecules to pass through but traps and retains the salts, the viruses and the organic chemicals that might be present in the wastewater.
In the second step in the process, we add a small amount of hydrogen peroxide and shine ultraviolet light on the water.
After the water's been through this two-stage process, it's safe to drink.
I know, I've been studying recycled water using every measurement technique known to modern science for the past 15 years.
And that's in stark contrast to the taken-for-granted water supplies that we regularly drink all the time.
There's another way we can recycle water.
The treatment wetland receives water from a part of the Santa Ana River that in the summertime consists almost entirely of wastewater effluent from cities like Riverside and San Bernardino.
The water comes into our treatment wetland, it's exposed to sunlight and algae and those break down the organic chemicals, remove the nutrients and inactivate the waterborne pathogens.
The water gets put back in the Santa Ana River, it flows down to Anaheim, gets taken out at Anaheim and percolated into the ground, and becomes the drinking water of the city of Anaheim, completing the trip from the sewers of Riverside County to the drinking water supply of Orange County.
That's enough water to be the supply of about a million people if it were their sole water supply.
The third tap that we need to open up will not be a tap at all, it will be a kind of virtual tap, it will be the water conservation that we manage to do.
And the place where we need to think about water conservation is outdoors because in California and other modern American cities, about half of our water use happens outdoors.
In the current drought, we've seen that it's possible to have our lawns survive and our plants survive with about half as much water.
The fourth and final water tap that we need to open up to solve our urban water problem will flow with desalinated seawater.
"It's a great thing to do if you have lots of oil, not a lot of water and you don't care about climate change."
Compared to the seawater desalination plant that was built in Santa Barbara 25 years ago, this treatment plant will use about half the energy to produce a gallon of water.
Among the different choices we have, it's probably the most energy-intensive and potentially environmentally damaging of the options to create a local water supply.
With these four sources of water, we can move away from our reliance on imported water.
Through reform in the way we landscape our surfaces and our properties, we can reduce outdoor water use by about 50 percent, thereby increasing the water supply by 25 percent.
We can recycle the water that makes it into the sewer, thereby increasing our water supply by 40 percent.
So, let's create a water supply that will be able to withstand any of the challenges that climate change throws at us in the coming years.
Let's create a water supply that uses local sources and leaves more water in the environment for fish and for food.
Let's create a water system that's consistent with out environmental values.
And let's do it for our children and our grandchildren and let's tell them this is the system that they have to take care of in the future because it's our last chance to create a new kind of water system.
