California Proposes ‘Toilet-to-Tap,’ Turning Wastewater into Drinking Water
Quote:California’s State Water Resources Control Board proposed regulations on Tuesday that would allow for “toilet-to-tap” programs that recycle wastewater and add it back to drinking water systems.
In a statement, the board said:
[T]he State Water Resources Control Board announced today proposed regulations that would allow for water systems to add wastewater that has been treated to levels meeting or exceeding all drinking water standards to their potable supplies. The process, known as direct potable reuse, will enable systems to generate a climate-resilient water source while reducing the amount of wastewater they release to rivers and the ocean.
…
Direct potable reuse relies entirely on immediate, multi-barrier treatment that can recycle wastewater to drinking water standards in a matter of hours. This contrasts to the method currently being deployed in major projects launched throughout the state, called indirect potable reuse, which further improves treated wastewater over time through groundwater recharge or dilution with surface water. While no formal direct potable reuse projects can be initiated in California until the regulations are adopted, water agencies in Santa Clara, San Diego and the city of Los Angeles have launched pilot projects in recent years.
Breitbart News described ongoing experiments with recycling wastewater in a series of articles in 2018-2019:
The Metropolitan Water District of Southern California has partnered with the Sanitation Districts in a new project to test the feasibility of treating and reusing a large percentage of the county’s water that is currently discharged to sea.
I was the first reporter to be allowed a look at a new demonstration project called the Advanced Purification Center, which, when operational, could result in a full-scale recycled water plant that would purify up to 150 million of the 250 million gallons per day that flow through the [Joint Water Pollution Control Plant in Los Angeles, or JWPCP].
The test facility, where construction began in 2017, will be completed later in 2019. It will purify about half a million gallons of water from JWPCP per day, using a special process that first uses microorganisms to remove ammonia and other nitrogen compounds from the water; then uses advanced filters to remove microorganisms and solids; and finally uses [reverse osmosis] membranes to purify the water, just as in a desalination plant.
The process is less expensive and less energy-intensive than desalination, because the treated water, while too salty for immediate use, is only about a tenth as salty as sea water.
Once proven, the plant could be expanded — and, officials told me, could be operational in 11 years, if all went as planned and the state approved all of the necessary permits.
The new regulations could be approved by the end of the year.

This is the wave of the future.
I think that in most cases using recycled water for outdoor irrigation would be socially acceptable and would put a pretty huge dent in our potable water usage. But there are already some places that have been hit with droughts and have mixed some recycled effluent in with their potable water supply.
Desalinization and recycled effluent would go a long way toward solving California's water problems.

it's sad all the $$$ that have been spent on unnecessary bs didn't go into desal tech...
honestly, I just don't care anymore ... those cockkksuckers deserve everything coming their way...
to the OP, they simply don't have much of a choice at this point, Ja?!!!

You're not supposed to say the quiet part out loud. It makes the people who can't think multidimensionally, much less beyond the tip of their nose, nervous.

Bleh, if you're drinking water you're drinking molecules that passed through the bladder of animals or people before. This was inevitable and probably should've been done years ago.

Sea World in San Diego (and I think the zoo) has a great program IMO. Still expensive as hell, but I think it could be worked out somehow....
They run 'used' sea water from their tanks through their urinals... which then enters the city water treatment system. There has to be some pretty significant areas like ball parks or industrial complexes or similar where economies of scale could be found... Perhaps some sort of combination, where (just throwing something against the wall) part of the water treatment is a removal of SOME of the salt... which is then diluted further by 'used' potable water... and then the water is sent to inland man-made 'brackinsh' lakes where mother nature removes more salt before returning it eventually to the oceans... IDK...
I see this as a way to do more effective desalinization for lower cost... as you aren't really trying to get the water all the way to 'drinkable'... just far enough to not harm the ecosystem.

I've drank water from some cities that are great for treating constipation. They have the same effects as the tacos from a local restaurant that people say gives them the Schiffs. Like in Dallas for instance it never failed, I always got loose stools from their water but unless I wanted to be dehydrated I had no choice but to drink it.
I can't imagine that El Paso as poor as it is can afford a desalination plant and rich Commiefornia can't or doesn't want to invest. They got more water close by and yet they shrink from that idea. I heard not too long ago that they even prohibited people storing their rainwater that was used for their lawns and gardens and that to me is that is one reason why people are leaving that beautiful, er, what used to be beautiful but now is rainbow hued with all those multi-colored tent cities. The people in those cities deserve what they get and I couldn't care less how they live. Every decision has consequences and now they're living their bad decisions.

My last and now current houses had "water treatment" septic tanks that had "potable" water coming out the end.
Even still, you cannot grow anything in the area of the run-off (their rules) and your run-off cannot entire any other water source, even a pond on the same property.
