My Water saving Theme


Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand. Population, household size, and growth and affluence all affect how much water is used.


 Water conservation refers to the preservation, control and development of water resources, both surface and groundwater, and prevention of pollution


 Water efficiency is reducing water wastage by measuring the amount of water required for a particular purpose and the amount of water used or delivered. Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use.Solutions for water efficiency focus not only on reducing the amount of potable water used, but also on reducing the use of non-potable water where appropriate (i.e. flushing toilet, watering landscape, etc.). It also emphasises the influence consumers can have in water efficiency by making small behavioural changes to reduce water wastage and by choosing more water efficient products.


 Examples of water efficient steps includes fixing leaking taps, taking showers rather than baths, installing displacements devices inside toilet cisterns, and using dishwashers and washing machines with full loads. These are things that fall under the definition of water efficiency, as their purpose is to obtain the desired result or level of service with the least necessary water


According to the Second UN World Water Development Report, if present levels of consumption continue, two-thirds of the global population will live in areas of water stress by 2025. Increasing human demand for water coupled with the effects of climate change mean that the future of our water supply is not secure. As of now, 2.6 billion people do not have safe drinking water. Added to this, are the changes in climate, population growth and lifestyles. The changes in human lifestyle and activities require more water per capita. This tightens the competition for water amongst agricultural, industrial, and human consumption

Water efficient solutions


Residential


Here are some simple ways to be more water efficient at home

  • Turning off the tap while brushing teeth - a running tap can waste over six liters per minute.
  • Putting a displacement device into the toilet cistern.
  • Installing aerators or flow reducer (NFR) of less flow on taps/faucet and reducing water wastage.
  • Installing water efficient showers in bathrooms for bathing.
  • Fixing dripping taps. A dripping tap wastes thousands of litres of water a year.
  • Using a full load in the dishwasher and washing machine. A person should be sure to buy a water efficient model when buying a new machine.
  • Having a short shower instead of a bath.
  • Washing fruits and vegetables in a bowl rather than under a running tap.
  • Using the leftover water to feed houseplants.
  • Using a watering can or a hosepipe with a trigger nozzle instead of a sprinkler.
  • Using a bucket and sponge when washing the car rather than a running hosepipe.
  • Using little amounts of water at every time
  • Washing clothing or linens in washing machines rather than washing by hand

Consumers can also voluntarily or with utility or government incentives or mandates purchase water-efficient appliances, such as low-flush toilets and front-loading washers. Greywater can be recycled for toilet flushing or garden use.


Manufacturing


According to Savewater!, these are solutions useful to manufacturers

  • Identifying and eliminating wastage (such as leaks) and inefficient processes (such as continual spray devices on stop-start production lines). This may be the most low cost area for water savings, as it involves minimal capital outlay. Savings can be made through implementing procedural changes, such as cleaning plant areas with brooms rather than water.
  • Changing processes and plant machinery. A retrofit of key plant equipment may increase efficiency. Alternatively, upgrades to more efficient models can be factored into planned maintenance and replacement schedules.
  • Reusing wastewater. As well as saving on mains water, this option may improve the reliability of supply, whilst reducing trade waste charges and associated environmental risks.

Waterless products


  • Using waterless car wash products to wash cars, boats, motorcycles and bicycles. This could save up to 150 gallons of water per wash.

Utilities


According to US EPA, here are some ideas for communities and utilities:

  • Implementing a water-loss management program (e.g. locate and repair leaks).
  • Utilities should strive for universal metering.
  • Ensuring that fire hydrants are tamper proof.
  • Equipment changes - Setting a good example by using water efficient equipment.
  • Installing faucet aerators and low flow shower heads in municipal buildings.
  • Replace worn out plumbing fixtures, appliances and equipment with water-saving models.
  • Minimizing the water used in space cooling equipment in accordance with manufacturer's recommendations. Shut off cooling units when not needed.

Utilities can also modify their billing software to track customers who have taken advantage of various utility sponsored water conservation initiatives (toilet rebates, irrigation rebates, etc.) to see which initiatives provide the greatest water savings for the least cost

My Energy Sector

The organization of the electrical sector of a country or region varies depending on the economic system of the country. In some places, all electric power generation, transmission and distribution is provided by a government controlled organization. Other regions have private or investor-owned utility companies, city or municipally owned companies, cooperative companies owned by their own customers, or combinations. Generation, transmission and distribution may be offered by a single company, or different organizations may provide each of these portions of the system India's power sector is one of the most diversified in the world. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste The electric power industry is commonly split up into four processes. These are electricity generation such as a power stati

My Emergency Evacuation plan

Emergency evacuation is the urgent immediate egress or escape of people away from an area that contains an imminent threat, an on-going threat or a hazard to lives or property. Examples range from the small scale evacuation of a building due to a storm or fire to the large scale evacuation of a city because of a flood, bombardment or approaching weather system . In situations involving hazardous materials or possible contamination , evacuees may be decontaminated prior to being transported out of the contaminated area Emergency evacuation plans are developed to ensure the safest and most efficient evacuation time of all expected residents of a structure, city, or region. A benchmark "evacuation time" for different hazards and conditions is established. These benchmarks can be established through using best practices, regulations, or using simulations , such as modeling the flow of people in a building, to determine the benchmark. Proper planning will use multip

My Travel and Early time

Travel is the movement of people between relatively distant geographical locations , and can involve travel by foot , bicycle , automobile , train , boat , bus , airplane , or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements A travel documentary is a documentary film , television program , or online series that describes travel in general or tourist attractions without recommending particular package deals or tour operators. A travelogue film is an early type of travel documentary, serving as an exploratory ethnographic film . The genre has been represented by television shows such as Across the Seven Seas , which showcased travelogues produced by third parties, and by occasional itinerant presentations of travelogues in theaters and other venues A horse and buggy (in American English ) or horse and carriage (in British English and American English ) refers to a
