3 ways you can reutilize grey water at home

Types Of Water

Types Of Water

Typically speaking, we can see three types of water at our places. Fresh water or tap water is good water that can be used for drinking. The fresh water when utilized can be categorized into two types. The used water after washing dishes, laundering, or bathing is called grey water. Any other water that is discharged from toilet wastes or kitchen is known as the black water. The grey water usually contains soap, oil, food particles, dirt, hair etc. but it can be reutilized after removal of the same. This has twofold benefits. First, it reduces the demand for fresh water required in a household for non-potable activities, and second, it minimizes the amount of wastewater entering the sewer, drains or septic systems.

Uses of grey water

This water can be used in many ways in homes or commercial building. Usually, commercial buildings may not generate grey water from the shower but sink water can be utilized further.

Indoor use:

It can be the best option for apartments or houses where the water consumption is high for non-potable activities. The water generated from the bathroom sink or the water wasted while warming the shower or bathing is not too dirty and can be reutilized. It can be collected in a bucket and can be used to flush the toilet instead of using the flush tank. A little change in the fittings of the bathrooms can help achieve the same and save the cumbersome activity of using the bucket. For example, the bathroom sink can be connected with the flush tank to collect the water in the flush tank every time the sink is used.

Laundry to landscape:

Another simpler way to reutilize it is using the laundry water to water the plants.  The water generated after laundry, provided you are not using chlorine, bleach or other harsh chemicals to wash clothes, can be collected in a bucket to replenish the water needs of the garden plants or even the plants on your balcony. The washing machine hose can be connected to a pipe that ends directly in the garden to send the laundry water to the garden every time the laundry is done. In case, you do not have gardens, the water can be collected to water the plants on the balcony or the terrace. If chemicals are used for washing, then this needs to be treated to remove the same so that it may not harm the plants.

Grey water generated from the bath tub:

Love taking a bath in the bathtub and ready to reuse the water, then that is the best place to start with. We usually need a good quantity of water for such activities which can be utilized further. This may require some changes in plumbing. The bath tub and the water drain that carries the shower water, are connected to the pipe that carries the water to the tank set up in the garden, to collect the water and reuse it to water the plants. Grey water stored in the tanks needs to be treated to remove the chemicals or soap from the water for further use.

These simple and smart methods of re-utilizing the water can help us combat water crisis in an economical manner.

5 Best places to use the harvested rainwater.

RainWater Harvesting

RainWater Harvesting

Rainwater is known to be the purest form of water available to us. As it requires minimum treatment before use as compared to other sources, it can be used for both indoor and outdoor purposes.

When we plan to incorporate the same in our house, the primary factor that needs attention is where we are planning to use it. This factor allows us to plan the system of the water flow accordingly.

There are numerous uses of rainwater and you can decide which option best suits you.

Use of  Harvested RainWater For Water For Garden

Use of Harvested RainWater For Water For Garden

The most common and the best use of rainwater is for irrigation. Again, as already said, it is the purest form of water which have minimum traces of chemicals. It is the best suitable option for plants. It is advisable to not to use tap or fresh water for irrigation. Rainwater maintains the balances of the nutrients of the soils and improves the productivity.

Use of Harvested RainWater For Washing For Vehicles

Use of Harvested RainWater For Washing For Vehicles

You can also use the rainwater for washing your vehicles. As it does not have chemical traces, the possibility of metal corrosion or decreasing the finish of the paint is minimised.

Other than this you can use the harvested water to wash the pavements, portico, outdoor parking area and so on.

In fact, we have more options to use the rainwater indoors. The daily usage for toilets, washing utensil, laundry and bathing accounts for 60-70% of freshwater. But if we give a closer thought most of the activities do not require fresh water or drinking water. These activities can be furnished by harvested rainwater
You can use the harvested rainwater for the toilets. Other than saving the fresh or drinking water, it also helps to keep the taps and valves clean and corrosion free as it lack salt responsible for the same.

Use of Harvested RainWater For Washing Clothes

Use of Harvested RainWater For Washing Clothes

If you use the same for the laundry, it being the soft water will require less of soap and do not leave traces of the salt on the clothes. This lead to less need of water for cleaning the laundry.

But for bathing or any other purpose that requires consumption or contact, it must be treated with approved chemicals. This will neutralize the effects of the chemical traces available in the water thus making it usable.

However for safety reasons it is still advisable to use some purification method before using the harvested rainwater for uses like dishwashing or bathing. The popular choices for the treatment is UV treatment with carbon filter. These units are easy to install and requires less maintenance and will ensure that the water thus received it pure and safe for use.

Once you are done with planning to use the rainwater, the next you can easily plan the plumbing system according the requirement. The rainwater harvesting is easily integrated with greywater and blackwater management for water recycling, efficiency and self-sustainability with respect of water.


Zero Water Building

Zero Water Building


Water is an invaluable resource and absolutely vital to life but many of the times taken for granted. Increasing population is demanding even more from our already crippled water and wastewater infrastructure. It is the need of an hour to think about alternate sources of clean water rather than just depending on municipal water supply, which is uncertain and sometimes unhealthy. By merely installing shower head with lesser flow rate or by reducing water consumption we are looking at short term solution. The time is demanding more. Get ready for “Self Sufficiency” in water.

What does zero water building mean?

Rainwater Harvesting  A Must To Be Self Sustainable Sanicon Energy Solution

Water harvesting is no different than renewable energy– opportunities abound in your building to capture a free resource and turn it into an economical solution. The integration of “zero water building systems ” that emphasize water efficiency, and on-site supply, treatment and reuse is becoming increasingly important as communities seek to strengthen the resiliency of their water systems.

By capturing precipitation and treating wastewater produced on site, occupants of a household will close the loop of their water system, thus leading to water independence.

The key component of sustainable building:

To understand the zero water building in depth we must know the major source of water inflow  to achieve the same.

The key source of water in self sustainable building is the direct source of water which is rain. It is a major source of water in building.

Understanding the concept of rainwater harvesting

Zero water building By Sanicon Energy Solution

Rainwater harvesting is the technique to collect, recharge the groundwater and use it later for various uses which is otherwise goes down the drains.The rainwater has its own characteristic qualities and can be used for various non-potable uses and with little treatment can be made available for potable activities. For rainwater harvesting, first the rainwater is collected from various hard surfaces such as roof tops and/or other types of manmade hard surfaces and collected in the underground pit for further treatment and use.

Rain water harvesting has many advantages. Mostimportant of those are

Dependence On Municipal water

Habit Of Wasting Water

Scarcity Of Water

To inculcate habit of conserving water

  • To restore groundwater
  • To minimize use of municipal water supply
  • To get the most out of rain water
  • To minimize soil erosion due to rains
  • To conserve surface water runoff during monsoon

Identifying the grey water and need to re-utilize it

Grey water after taking shower

Commonly, most of the water consumption at home is for washing laundry, mopping, cleaning, bathing, toilet flushes, irrigation, etc. and the potable water is used to fulfill pretty much of all these. The water once used for bathroom sink, showers, bath tubs and clothes is called grey water and is nutrient rich and is best suitable for plants. And the water generated from kitchen sink and toilet is known as blackwater. At places where there is no human contact, such as toilet flushes and sub – soil irrigation of non-edible crops, we do not need fresh, potable water. We can treat greywater produced on site by bathtub/shower, washing machine, and bathroom sink and return them back into the system for these types of uses.

Bacteria-Infused Material Pulls Energy Out of Poop

​You’ve probably never thought of the toilet this way, but from a chemist’s perspective, your average flush is a goldmine of untapped chemical energy. Over the past few decades, scientists and engineers have tested various ways to reclaim raw sewage’s wasted energy and recycle it back into sewage treatment. The methods have ranged from the practical—extracting methane by fermentation—to the futuristic: creating bacteria-powered fuel cells.

 Yes, giant poop-powered batteries.
Today a team of materials scientists and wastewater engineers, led by Shenlong Zhao at the Harbin Institute of Technology in Harbin, China, announced a curious new material for creating sewage-based bacterial fuel cells. They created a porous, pumice-like material out graphene that is studded with tiny particles of platinum. The material can harbor colonies of waste-eating bacteria while siphoning off bacterial electrolytes to create tiny amounts of usable energy.

In their test, documented in the study in Science Advances, the researchers grew a strain of bacteria (Shewanella oneidensis) on their new material. Placed in untreated sewage taken directly from a municipal wastewater treatment plant in Beijing, a large swath of the microbe-infested material produced enough energy to power a small, wristwatch sized timer.

“We’ve found the graphene is very bio-compatible for bacteria, and the small amount of platinum particles is a very good medium for [energy] transfer,” says Zhiyong Tang, a materials scientist with the team at the National Center for Nanoscience and Technology in Beijing. “It’s a very exciting step for future research,” he says, though noting that “our material still has many improvements that need to be made.”

Judging by the responses we got from independent engineers, that may be an understatement. Craig Criddle, an environmental engineer at Stanford University who was not involved in the research, says that while the research is interesting, it’s far from impressive—at least in terms of practical performance. The big challenge for microbial fuel cells like Zhao’s is to boost energy efficiency (how well they utilize sewage’s total chemical potential) while staying affordable. Criddle says this new material overcomes neither hurdle. It has less than 0.1 percent total efficiency and a requires expensive platinum metal.

That’s not all. “Any device like this is going to need to prove it can run for long periods of time. Not hours, nor days, but years. Because in a [treatment plant] waste water just keeps on coming, nonstop,” he says.

Bruce Logan, an expert on microbial wastewater treatment at Penn State who was likewise not  involved in the new research, is in resounding agreement. “The system requires a precious metal for the anode (platinum),” and incredibly large surface areas to produce even a tiny amount of appreciable power, Logan tells PM via email.

By comparison, Criddle points to another method of energy reclamation that many sewage treatment plants across the country are already using: methane fermentation. By farming a slew of microbes that expel methane in sewage (imaging fermenting the worst beer imaginable), treatment plants can capture the gas, and burn it later to offset their energy costs. Any new system of energy generation, Criddle says, will have to prove itself substantively better than the existing methane fermentation approach.

How D.C. Is Going To Drill a Tunnel Through Frozen Ground

Groundwater is not a friend of folks who dig tunnels. And just like with a pesky person you don’t want around, the best way to deal with the problem is to freeze them out.

Crews from Skanska USA are embarking on a project to bore a 2,700-foot-long, 20-foot-diameter tunnel 80 to 160 feet below the Washington, D.C., neighborhoods of Bloomingdale and LeDroit Park. When complete, the project will provide nine million gallons of water runoff storage to alleviate the flooding that’s all to common in this dense residential area with a sewage and drainage system designed in the late 1800s. And to complete the DC Water First Street Tunnel Project, they’re going to freeze the ground and drill through the chill.

In the case of underground infrastructure projects, freezing ground not only keeps groundwater away from a worksite, but also creates a more efficient and quieter project—good news when you’re boring below a neighborhood. Scott Hoffman, Skanska project manager, tells PopMech that various jobs will use the century-old technique of ground freezing. “What makes this job unique is the way we are applying it in the middle of a densely urbanized area. We have a lower profile operation and can run the freeze sites remotely.”

There’s no getting around it: Working underground mean dealing with groundwater. Traditionally, a tunnel project like this might us massive pumping systems—think large and loud equipment—or grouting techniques to keep water from pushing up and flooding a newly bored tunnel. But those methods can prove bulky and unreliable. For example, Hoffman says, a grouting system has trouble solidifying soft ground behind rocks.

Not so with freezing all the ground in the area. “The cooling of the freeze pipes will pervade through everything in the area,” he says. “It is a secure way of excavation.”

To get started, Skanska subcontractor Moretrench, with the design help of Parsons Brinckerhoff, sunk 331 four-inch-diameter steel pipes to a depth of about 150 feet. The drilling locations were chosen to ensure total coverage of the excavation area. The project requires the drilling of a series of 90-foot-shafts ranging from 21 to 23 feet in diameter. Two “drop” shafts will convey overflow water from diversion chambers to the tunnel, and a smaller shaft will connect to the pump station and the existing sewer system. So the steel freeze pipes drop to almost twice that depth, hitting rock at the bottom to form a seal and keep groundwater from pushing up.

Hoffman says freezing around the perimeter and down to the rock creates a double protection and eliminates the power of deep-water pressure. “Once you get an inflow,” he says, “it can be difficult to stop.” Each pipe can freeze the ground six to eight feet around it, if it’s near the surface, and up to nine feet around it if it’s lower down. Crews use foam insulation near the surface to maintain the cold temperatures.

Getting the ground cold requires the use of a giant refrigeration system. Three tractor-trailer units, each 45 feet long, park nearby and use ammonia to cool a brine-saltwater mixture—the same mixture used to treat roads in the winter—to a range between -15 and -22 degrees Fahrenheit. The system moves 1,000 gallons of solution every minute via 50 horsepower pumps, all controlled remotely by a mobile app.

It took six to eight weeks to form the initial freeze and the closed-loop system maintains the temperature while it is “monitored continuously” by mobile app without the need for intrusive equipment.

With the ground frozen, crews can mine these shafts without the fear of groundwater seeping up and overtaking the tunnel or messing with the tunnel-boring machine. This project’s TBM was named Lucy. As Lucy pushes forward, crews apply shotcrete—a spray concrete—in a sequential excavation method that has the project currently about one-third completed, and on track for an April 2016 finish.

As Lucy churns through the clay-filled frozen ground, the hardness of the soil requires a mixture of tools on the cutterhead face, including using 16 disc cutters that can more easily handle the solid ground, two rippers, 78 scraper knives, and 28 bucket lips. Hoffman says that even though the ground was frozen, the disc cutters have kept the project moving along nicely, even through frozen ground.

Solar Energy Making Ultra-Green Homes of the Future a Modern Day Reality

Zero-net energy Greenbuild Unity Home featuring fully-integrated SunPower home solar solution

SAN JOSE, Calif., Nov. 17, 2015 /PRNewswire/ — Energy-efficient homes of the future have arrived and are growing in popularity. According to a report by McGraw Hill Construction, nearly one-third of new single-family homes in the U.S. will be green by 2016. They are energy and natural resource efficient, designed to reduce overall impact on human health and the environment. An increased number of consumers are going a step further and striving for net-zero energy homes that use renewable energy solutions, such as solar power systems, to offset all or most of their energy consumption. Across the country, the number of net-zero energy residential and commercial buildings doubled between 2012 and 2014 as cited by the New Buildings Institute.

Experts predict the trend will continue. This is partly because reliable solar has become more accessible and affordable than ever, delivering dramatic energy savings to customers. The Solar Energy Industries Association reports that since 2006, the price to install solar has plummeted by more than 70 percent, and innovative technologies are making solar panels increasingly more efficient. Today there are close to one million solar energy systems operating in the U.S., which in terms of reduced carbon emissions is the equivalent of taking 5.4 million vehicles off the road each year.

“Homeowners across the U.S. are opting for green homes to maximize energy efficiency while increasing electricity savings, and SunPower has partnerships with eight of the top ten homebuilders nationwide to meet this consumer demand with reliable solar energy solutions,” said Tom Werner, president and CEO of SunPower, one of the world’s most innovative solar companies known for the industry’s most efficient commercially available solar panels. SunPower is also the first and only solar manufacturer to earn the prestigious Cradle to Cradle Certified™ Silver designation for its panels manufactured in Mexico and France, comprising 75 percent of shipments globally.

“The future of energy is giving customers the power to choose where their electricity comes from, when they use it, and at what price,” Werner continued. “SunPower is paving the way with a fully-integrated approach to solar power, providing solar panels that deliver 70 percent more energy than conventional panels in the same amount of roof space, and energy management software that enables homeowners to set goals and take control of their energy future.”
