12 Initiatives To Save Water

The importance of water in life is known to everyone and we all understand the need for its conservation. It is the need of the hour to stand together and join hands in its conservation. Along with simple habits of saving it, we can also opt for smarter solutions like rainwater harvesting, greywater management system and convert our homes into zero water buildings, which are environment-friendly and water efficient.

Some Temporary Solutions To Change Habits
Let us see what we can change in our habits to save it :

Check the leaks

Leaks in the toilets

Keep a check on the faulty leaks from flush, faucets and pipes. Imagine even if the leak is merely a drip, you can fill a bucket in three hours, eight buckets in a day and 240 buckets in a month.

Use it wisely

Use Water Wisely While brushing

Simply keep the tap off  while brushing or washing your face or hands. You can turn it on when the cleaning is done and you actually need to use the water.

Washing clothes
We can opt to wash a full load in washing machines rather than few clothes at a time. Even if you opt to wash clothes with your hands, hold water in the bucket and turn the tap off when the bucket is full.

Flush only what is meant to be there

Flushing

We usually treat the flush as a replacement of the trashcan. Insects, hair, papers are flushed in it off and on. This not only wastes water but can also choke the drain, which will make you incur extra time and cost in repair.

Reduce shower spanShower

Everyone loves to wash all the tiredness under the shower. A long shower with temperature controlled water is all that we need. You may choose to lower shower heads along with the time in the shower in a step towards reducing water wastage.

Outdoor wastage
The wastage should be controlled even outside the house. You may be guessing that there is no place where we are using water outside but rethink.

 Washing carWhile washing car

Prefer washing cars with a bucket rather than running splash. You may even use laundry water to wash your car.

Pavement wash:
A shining pavement at the entrance gives great impressions to the visitors, but you actually do not need to wash it regularly rather, try mopping the pavement and use laundry or mopping water for the same.

Check the sprinklers and pipes:

Keep a check on the sprinklers and pipes to avoid leak and sprinkler directions to ensure that it is watering the garden and not the road or pavement. Also do not use sprinklers working for long. This will damage the plants. Prefer using drip irrigation method.

Watering the plants:
Do not over water the plants. This will not only ruin them but also accounts for wastage. You can also recycle water from kitchens and laundry, rich in nutrients, for the garden.

Permanent Solution or Smarter Option Rainwater harvesting with
wastewater management:
There is another smart and permanent solution to rectify the problem of wastage due to our non-changeable habit. We can convert our homes into Zero Water Building (a building that doesn’t take any drop of water from municipal corporation neither discharge any), which simply closes the loop to save water completely.

Why Greywater Management System Is Needed

Water is the primary need of any living creature on the planet. With the growing population and urbanization, the availability of the consumable water is diminishing. The growth of the economy or the population cannot be controlled. But with change in sensitivity towards the consumption of water, we can meet the present demands and optimum use of the same can help to save our future generations.

The quality and the quantity of the available water is depleting due to population and pollution which is driving the governments to set the laws for conservation of the water resources and greywater management system is one of the significant methods to achieve the same.

is-greywater-management-needed.jpg

Greywater is the reclaimed water that has been used once in domestic, commercial or industrial activities and can be reutilized after treating up to standard limits for certain tasks.

This greywater can be treated through various technologies depending on the nature of reuse for further applications like car washing, irrigation, toilet flushing or street cleaning.

The current Indian scenario

The current Indian scenario

Water is becoming a rare resource in the world. In India, it has been projected by International water management institute that by 2025, one third of the population will live in complete water scarcity.

With the rapid increase in the population and demand for fresh water the available resources are depleting day by day. The per capita surface water, which was available at 2300 m3 (6.3 m3/day) in 1991 has depleted to 1980 m3 (5.7 m3/day) in 2001 and is projected to deplete to 1191 m3 by 2050. And the water requirement is projected to 1450 Km3 in 2050 as compared to 1086 Km3 presently. Hence, it is very crucial to reduce the use of surface and groundwater in all sectors, find alternatives to fresh water reuse option for optimization of the available water. The alternatives include rainwater harvesting and greywater management system and reutilization for meeting the projected deficit.

GREYWATER

The wastewater is generated from various activities like washing, laundry, bathing, mopping, flushing, cooking, etc. This water is categorized into three types depending upon the level of contaminants present in the source. They are black water, dark grey water and light grey water. Black water is generated from the flush and are high in disease causing microorganisms. Dark grey water is the water  that originates from the kitchen sink, which also contains disease causing germs and organic contaminant from food waste and grease or oils. Light-greywater is originated from bathroom sink, tubs, showers and laundry. This water also contains disease causing microorganisms but in lower number as compared to the other two types. The level of organic contaminants is also less in this type of water. The figure shows how much water is discharged as wastewater in regular household activities.

Benefits of greywater reuse

  • The first and the foremost reason of greywater management and reuse is to replace or conserve the freshwater for other potable uses.
  • The greywater is rich in nutrients like phosphorus and nitrogen that are present in detergents, which are good for the plants. The water generated from laundry if used appropriately can help in good vegetation and plant growth.
  • Reduces the cost incurred in sewage treatment. Greywater when treated and used within the area minimises the wastage through sewer lines and cost incurred in its treatment at sewer cleaning facilities.
  • Usually the reutilization of the greywater require no or minimal treatment before use.
  • Greywater can help to supply most of the water needs for irrigation purposes.

These various methods can be used to treat the same from low level of complexities for basic uses like gardening or flushing to high level of treatments to remove sediments, oil and grease, chemicals, odour and other impurities depending upon the nature of reuse.

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:

Indoor Use Of Grey Water

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.

What is a Sustainable Green Building?

sustainable-green-building

Sustainable Green Building is a concept that has gained popularity at a global level in the past few years. This is due to the fact that for a green building, starting from its construction it is ensured that waste is minimised at every level. The materials used are not only of superior quality but also eco-friendly. According to the experts, this not only minimises our carbon footprint but also results in lower costs in the long run. Hence, we can say that a green building is constructed in such a way that they reduce their overall impact on natural environment and as a result on the human health by:

1. Using the energy, water and other resources judiciously and efficiently.
2. Protecting the environment and improving human health conditions.
3. Effectively minimizing the waste production, pollution and environment deterioration. 4. Using natural resources like natural light wherever possible to effectively manage the use of energy.

In order to achieve the minimum energy consumption level, following features are incorporated in a green building which makes them earth friendly: 

1) The walls are designed to keep out the moisture and humidity in the outside air which makes the building naturally cooler. This reduces the use of air conditioners.

2) Low Solar Gain. Solar gain is the increase in temperature resulted from the solar radiation. With low solar gains, the building remains much cooler which again reduces the need for air-conditioners.

3) Using water efficient faucets ensures that less amount of water is utilised to perform the same function as compared to their traditional counterparts.

4) Rainwater Harvesting systems are installed to catch the natural rain water to  cater to the building’s water needs.

5) Wastewater treatment plants for minimising the waste water expulsion from the building and effective water management with water recycling.

6) Installing hydroponics system to increase the green belt while reusing the water through utilising treated greywater.

7) Creating waste management plants on the site such as compost pits to utilise the building’s biodegradable waste for fertilizers.

8) Installing clean energy sources such as solar panels, solar water heaters etc for electrification.

The green building concept has a vast benefit cover can be effectively employed for various sites, some of which are: 

1. Residential buildings
2. Office Complexes
3. Institutional buildings such as schools, colleges etc
4. Retail buildings
5. Hotels
6. Hospitals
7. Government Buildings

The concept of green building, however new, aims at using natural building materials during  not only construction, but also adopts other methods, such as rainwater harvesting for its water needs, solar energy for the electrification, waste management, etc. Hence making the making green building self sufficient when it comes to the energy requirement. The efficient usage of natural resources and their further recycling, ensures sustainability in the long run.
