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.

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.

How good are sustainable homes for owners and nature.

Benefits Of Sustainable Homes

Benefits Of Sustainable Homes

A sustainable home is the one that is simple on both the environment and the pocket. A “green” or “sustainable” home is not only natural and environment-friendly but also durable and healthy. They may look similar to regular homes from outside but has a lot more difference in their construction and functioning. While they are nature-friendly, they offer numerous benefits to the home owners as well. It can also be an investment and end up saving you money in the long run.

Benefit to nature:

The sustainable or green homes are build up using fewer natural resources in the construction of a green home. Numerous green building materials are made of a lot of reused substance which leaves less destructive impact in the earth. The use of less polluting materials and minimum landfills minimizes the waste and saves the land.

The green homes make use of renewable energy like solar energy for meeting its demand for power supply. The use of solar panels, solar heaters, energy star rated appliances leads to minimum carbon emission and saving of fuel.

Also, efficient plumbing and bathing fixtures, waste water management, drought-tolerant landscaping, rainwater harvesting and water-conserving irrigation systems helps in minimum use of fresh water as compared to standard homes.

Benefits to the owners:

The green homes are cost effective. The high-quality building material and advanced construction methods leads to reduction in monthly maintenance costs. The use of energy saving appliances, natural solar panels and solar heaters low flow fixtures and water saving techniques minimizes the burden on the utility bill without compromising on the luxury of the home owners.

These offer a higher resale value as compared to the standard homes while it gives a natural and healthy environment to the residents

The use of Toxin-free building materials, paints and other products will give healthy and pure environment and fight air pollution. The natural ventilation mechanism channelize and bring natural air inside and vent stale air outside to keep germs and moisture away that cause respiratory diseases linked with molds and stale air.

A sustainable home is intended to fit the residents’ necessities and adjust to their evolving prerequisites. The green homes of today are smart, perfectly completed, perpetually with warm and light spaces for living – and by and large they look simply like a standard house with added benefits.

 

3 most common issues in the kitchen plumbing system.

kitchen

kitchen

Kitchen is the most common place in the house that requires continuous use of water.This leads to plumbing issues cropping now and then, which  if left unattended may lead to major disasters and heavy expenses for homeowners. These issues can be categorised into three heads: Leaks, clogs and water pressure issue. Let us elaborate on each category in detail:

Leaks

Leaky Kitchen Faucet

Leaky Kitchen Faucet

The most common plumbing issue that can be found in the kitchen the leaking faucets and sinks.This also counts for the water wastage and dribbling sound. The leaks in the faucet can be due to deterred aerator which is a little screen on the end of your spigot. You may try to let the water flow without the aerator for a while and then fix everything again and check for leaks again. If it continues, then the issue could be with the washer or the O ring seal. The leakage from the sink can be due to some breakage in the drainpipes. Prefer calling the plumber for this if you do not want to experiment doing the same yourself

Clogs:

Clogged Drains

Clogged Drains

The another common but major problem that one faces in the kitchen is the clogs in the drains and sinks. This is due to continuous disposal of garbage, grease, soap and other garbage that continuously flows down. The non dissolvable materials like grease, oil, soaps and other solid wastes lead to clogging of the drains. This often blocks the p trap beneath the kitchen sink that is meant to keep the sewer gas far from home. You can notice the issue of clogs cropping when you notice that the water is moving down slowly than usual. There are multiple ways you can try to fix  the clogs of the sinks like plunger, vinegar and baking soda solution in it, etc but if nothing works best is to get the help of the expert.

Water pressure:

water pressure

This is the third most common issue in the kitchen. This can be noticed from the taps or water heaters. The low water pressure from the faucets can be due to the clogged aerator. While the low water pressure issue from the water heater can be due to various factors like too small heater to get enough water supply, clogged pipes, or old fittings. This needs an attention of the professional if you do not hold technical knowledge of the water heaters.

Although these issues at the initial stage seems very small or are often left unnoticed. But this leads to the situation getting worse that unfortunately happens at the wee hours of the day.

India’s ‘first solar-powered train’: All you want to know about Indian Railways’ green initiative

Indian RailwaysAs a green initiative of indian railway, the first solar panel fitted train is all set to commence trial shortly on the Jodhpur division of North western railways. All the six coaches of the train will be fitted with 12 solar panels on each coach. Each panel will generate 300 w of the electricity which means 3.6 KW of power for each coach. This will be enough to run light and fans inside the coach but not sufficient for ACs coach. However, the power supply would not be enough for running  air-conditioners inside the coach.
