The Complete Beginner’s Guide to Greywater Systems

"There’s a reason that a key component of green building is water efficiency and reuse. Nationwide water use statistics are nothing short of staggering. According to the U.S. Environmental Protection Agency (EPA), the average American uses 82 gallons of water per day. Nationwide, landscape irrigation and other outdoor uses account for nearly one-third of all residential water use, average, totaling nearly 8 billion gallons per day. And some experts estimate that as much as 50 percent of water used for irrigation is wasted due to evaporation, wind, or runoff caused by inefficient irrigation methods and systems. That means billions of gallons of clean, fresh water is wasted daily, due to ineffective irrigation systems.

You may be thinking, 'there’s got to be a better way. How can I reduce my home’s outdoor water use?' You’re in luck — there’s a very simple, easy, and inexpensive way to do so. Greywater systems redirect greywater (water used for washing) from going into the sewer system and into an irrigation system instead. For any eco-friendly home, recycling usable water is definitely something to seriously consider. Installing a greywater system means you’ll conserve water and reduce your monthly utility bills, all while providing valuable nutrients to your landscape and garden.

What is greywater?

Greywater is the name given to water that’s already been used for washing purposes, like laundry, handwashing, showering, and bathing (NOT water that’s been in contact with feces, like from the toilet or washing diapers). Greywater systems, then, are used to redirect and recycle this 'once-used' water for other purposes. Greywater may look unclean (it does have the characteristic 'grey' tint, after all), but it’s perfectly suitable for watering the garden, irrigating your trees, and more.

Is greywater safe for plants?

For the purposes greywater typically serves, like irrigating landscaping, ornamental gardens, or trees, greywater is safe (if you use the right cleaners and body care products) — and can even be beneficial. Greywater contains traces of dirt, food, grease, and hair, which become pollutants when released into bodies of water. But to plants, these things are nutrients and valuable fertilizers. This makes greywater an even better option for watering and irrigation than regular water!

(Note: If you want to use greywater for your vegetable garden, just be sure it doesn’t touch any edible parts of the plant.)"

How To Build A #DIY #Greywater System (Complete Guide)

January 9, 2022 by Dylan Crosbie

"Welcome to our complete guide to building your DIY greywater system!

A greywater system will decrease your carbon footprint, save water and decrease your utility bills. The system recycles water from your home and allows you to use it again for irrigation and flushing toilets.

It can be a simple, low-tech system that will be cost-effective in the long run and lower your water usage by up to 40%."

Where ‘#DayZeroDroughts’ could happen as soon as this decade

Story by Laura Paddison, September 23, 2025

Excerpt: "Cities are particularly at risk as booming populations increase demand on water resources already under pressure from #ClimateChange and mismanagement. Low-income communities are expected to be disproportionately affected, the study found.

"Some parts of the world, including the Mediterranean, southern Africa, Asia and Australia, are projected to endure more prolonged day-zero drought events with less time between each one, limiting their ability to recover, the report found. This can have devastating effects on agriculture and ecosystems, and for some particularly badly affected areas, it throws into question 'whether people might still be able to live there long term,' Franzke said.

The findings point to the clear need to speed up the clean energy transition, he said, as well as improve water management — huge amounts are wasted through leaky pipes, for example.

"The research should also guide industry, he added, pointing to the proliferation of water-guzzling #SemiconductorManufacturing and #DataCenters in water-stressed areas such as #Texas and #Arizona."

Tribes, enviros speak out against trailer bills to fast-track #DeltaTunnel project

“Delta tribes deserve a responsible and equitable approach to water management in the state that does not require jamming a tunnel through the Delta, destroying our ancestral homelands and waterways, or desecrating sacred sites and ancestral remains,” said Malissa Tayaba, Vice Chair with the #ShingleSpringsBand of #MiwokIndians.

Sacramento, CA – "On an unusually mild summer day, Tribal leaders and environmental justice advocates met with legislators at the State Capitol on July 16 for the 2025 Day of Action for #WaterJustice.

"They urged the legislators to reject Governor Newsom’s proposed trailer bills that they say would fast-track the Delta Conveyance Project (#DCP) and bypass critical #EnvironmentalProtections at a time when the Sacramento-San Joaquin River Delta is in unprecedented ecological crisis — and a number of fish species are on the edge of #extinction.

"The day-long event started with meetings between Tribal members, environmental advocates and legislators to urge support for 'equitable, science-based water solutions' that protect the #BayDelta and to reject the financially reckless Delta Conveyance Project that threatens ecosystems, Tribal sovereignty, and public health, according to a statement from #RestoreTheDelta.

[...]

"At the press conference on the Capitol steps, advocates called on lawmakers to reject trailer bills that would provide CEQA exemptions for the #DeltaConveyanceProject, circumventing existing law, court rulings and public opinion.

"Specifically, the coalition called on lawmakers to:

- Vote NO on SB 72 that undermines the #DeltaReformAct and sets arbitrary water supply targets;

- Vote YES on AB 362 that protects tribal beneficial uses of water and to;

- Vote YES on AB 263, extending emergency protections currently in place for the #ScottRiver and #ShastaRiver, a high priority for the recovery of #CohoSalmon.

"Speakers at the press conference included representatives from the Shingle Springs Band of Miwok Indians and the #WinnememWintu Tribe, as well as elected leaders and representatives from Restore the Delta, #SierraClub California, #FriendsOfTheRiver, #DefendersOfWildlife, #SanFranciscoBaykeeper and the #DeltaCountiesCoalition.

"Malissa Tayaba, Vice Chair with the Shingle Springs Band of Miwok Indians, began the press conference emphasizing the harm that the Delta Tunnel would cause to Tribes and #disadvantaged communities.

" 'Delta tribes deserve a responsible and equitable approach to water management in the state that does not require jamming a tunnel through the Delta, destroying our #AncestralHomelands and waterways, or desecrating #SacredSites and ancestral remains,' said Tayaba. 'Our culture and identities are intrinsically tied to the Delta. There is no price tag worth paying that would ever justify the harm done to us or the unquantifiable costs that Tribes and disadvantaged communities would ultimately bear.'

"Gary Mulcahy, Government Liaison with the Winnemem Wintu Tribe, followed Tayaba by stating, “There is nothing about the Delta Tunnel Project that significantly benefits anyone except #BigAg and south of the Delta water agencies, while putting #EndangeredSpecies, tribal cultural resources, and disadvantaged communities and the viability of the S.F Bay-Delta itself at risk. #CEQA exemptions continue to attempt to erase Tribes from #WaterGovernance.”

[...]

" 'Instead of wasting ratepayer money to keep pushing this expensive environmental justice debacle, we need to sees investments in local water supply like #RecycledWater, and the Freshwater Pathways program that would improve Delta levees to keep communities safe and improve State Water Project reliability in an emergency. We urge a commitment to vote NO on the return the Delta Conveyance Project and Bay Delta Water Quality Control Plan bills,' Wagner said."
