God has given Water to the World as the Holy sacrament gift and ordered not to tolerate spoiling water, for He has not done it.
In our lifetime – our days filled with perpetual race for all kinds of benefits, wealth, the lifetime of the oil idol and the golden calf, – only belief in Water and devotion to Water, its miracle cure for securing health, for soil fertility, for saving the beautiful all can put the will of God into action!

For plenty of people, getting a drink of water on the hottest of days is not as easy as filling a glass at the tap. Instead, they walk miles to the nearest well. Or they pay big fractions of their incomes — more than the average person in a developed country pays — to have a distributor truck in water, which may not even be clean.
Only 42 percent of Nigerians have access to drinking water. The rest of the population must go directly to the source in rivers or natural storm-water reserves, which could be purified by the Slingshot
About one in six people, as of 2005, couldn’t access clean water. But no one can live without water, so it’s often that people without access to a clean water supply end up drinking water laced with chemicals or populated by disease-causing organisms, which can kill children and shorten adults’ lives.
With this in mind, it’s easy to see why the World Health Organization put access to safe drinking water on its list of Millennium Development Goals, or targets to meet by 2015. But can it be done? Each pocket of people suffering water stress needs an affordable method that fits the local conditions and lifestyle.
Chlorine tablets and clay pots, boiling and cloth filters, sun barrels and rain barrels, and filter-equipped straws that can be worn on a necklace have all been tried, but some people still lack a method that works for them. Read more
Until recently, many cities had no legal distinction between gray and black water, rendering most domestic reclamation efforts technically illegal. But due to increased concerns over droughts and water shortages, some residents and local leaders are pushing for updated laws to allow the regulated use of gray water reclamation.
Would widespread gray water reclamation help or hinder sewage treatment plants such as this one in Santiago, Chili? Some say that without gray water to move waste along, sewage might not make it all the way to the treatment facility.
And where there’s demand, industry can’t be far behind. Companies are now offering gray water systems, pre-construction consultation and custom installation, in addition to working on new technologies.
Still, a gray water reclamation system that is legal in one city may be deemed a health hazard in another. Some regions still classify gray water as sewage, while others provide residents with basic health and safety guides for reusing gray water.
Across the globe, the scope of gray water reclamation varies greatly. Australia and New Zealandhave been ahead of the game for years, providing the local regulations, guidance and education needed for residents to make the most of their waste water. Mexico has begun using treated gray water for irrigation. However, in some less-developed nations, things are less encouraging. While gray water reclamation may not be prohibited by law in poorer nations, often there are far worse substances than soap suds draining into the soil. Ironically, the strict laws gray water advocates are fighting to overcome in developed nations were originally instituted to protect the environment and public health. Read more
While the particulars of a gray water diversion or filtration system can vary greatly, several basic steps are commonly used.
A hand-activated valve serves as an important first step in many systems, especially the more basic diversion systems. This valve allows a person to decide when water from a bathroom sink, tub or washing machine will be diverted to the garden and when it will go into the sewage system or septic tank. This level of regulation comes in handy to avoid overwatering during times of heavy rain or sending harmful chemicals or diaper water out to the garden.
After gray water is diverted down a system of pipes, its first stop on its trip to the garden is a basic filter — generally a mesh screen — to eliminate larger particles, before entry into a surge tank. The surge tank is used to help regulate flow by temporarily storing large amounts of gray water. This helps ensure a bathtub’s worth of drainage doesn’t all rush into the garden at once, while also preventing it from backing up into the home. Read more
Most methods of gray water reclamation, from lugging around a full bucket to diverting the water through a costly treatment system, involve a simple cycle:
- White water is pumped into the home and is used in showers, bathtubs, sinks, dishwashers, laundry rooms and toilets.
- White water that comes into contact with human waste becomes black water; the rest becomes reusable gray water.
- Gray water is reused for domestic purposes when appropriate. Black water is sent into a septic tank or sewage system, along with any unused gray water.
Gray water reclamation doesn’t have to be difficult. It can be as easy as taking a bucket with you into the shower.
When pipes are used to divert gray water, take care to prevent pumps and filters from clogging with bits of hair, skin and food. When clogs do occur, it is worth remembering that chemical clog removers are just the kind of harsh chemicals you don’t want to send directly into your garden. Natural solutions, such as boiling water or vinegar and baking soda treatments, might be less damaging to plant life. Additional safety precautions often depend on the specifics of the reclamation system in place, desired vegetation and the home’s residents. Gray water laws also vary from place to place. This issue will be discussed later.
Three basic gray water reclamation systems are commonly used. The main differences involve the scope, complexity and cost of the reclamation process. Read more
For the most part, plants aren’t as picky as people when it comes to drinking water.
To understand how gray water is absorbed by soil and plants, imagine emptying your backpack on the subway. That pile of stuff is much like gray water. It consists of various items that are useful or useless to the environment you introduced them to. There are certain items that will lie untouched — perhaps your smelly gym clothes or a really boring book. Plants and soil are much like the other train commuters. They’re ready to snatch the items they have the most use for and leave the less attractive ones behind.
Plants and soil work hard to break down gray water. Soil filters out many contaminants through a basic process:
- As water passes through layers of sand or granulated rock, larger water contaminants are caught in the grit of the dirt’s solids. This process is like straining solids out of soup with a colander, on a smaller scale. (If this sounds far fetched, remember that one key component in commercial water filters is charcoal.) The dirt itself helps filter out nutrients and biodegradable materials, which can then be absorbed by plants and bacteria.
- Microorganisms and bacteria in the ground feed off of carbon and pathogens, leaving water, carbon dioxide and non-polluting insolubles.
- The rest of the water, now purged of major pollutants, is absorbed by plants or seeps down to recharge the groundwater.
It’s important to remember that plant life varies greatly, and some species are unable to deal with the chemicals, salt or acidity levels in gray water. Other plants just call for careful watering and care to begin with. In many situations, drainage from kitchen sinks and dishwashers is too contaminated by grease and high acidity to be used at all.
