World Water Day 2014 and India

Let us think for a moment what is the significance of World Water Day specially for Countries like India where we already have a high population pressure on all natural resources and inefficient management at the same time. Let us not forget that of all the water that is available , only a very small fraction (~ 1 %) is available for use. What can we do to better utilize water resources and stop its wastage, below are some day to day practices that we can follow:

How to conserve the water in your home

1. Check for leaks, especially faulty washers, and repair them. It saves money too in long term.
2. Install water conserving fixtures and devices like below
o Spray taps and faucet aerators are an alternative to steady flow taps enabling a smaller volume of water to achieve the same results.
o Low-flow shower heads can be installed to maximize water coverage and minimize water volume.
o In the toilet: By adding a sealed plastic bottle filled with water inside your toilet tank or by adjusting your ballcock, the amount of water used per flush can be reduced to a minimum. Alternatively a dual flush toilet system can be installed which uses a small volume of water for liquid waste and a larger volume for solid waste, efficient flushing depends upon the velocity of the water rather than the volume which tends to be grossly out of proportion with the waste that the water flushes.
o Install a compost toilet, if appropriate: you can do away with using water to flush away your wastes. The added benefit to this simple technology is the rich compost you get at the end of the process, returning nutrients back to the soil that would otherwise end up in rivers. In China and Japan night soil (as it is called) has been scrupulously collected for centuries to fertilise the fields. Compost toilets need no water and depend upon bacterial action to break down harmful bugs in the waste.
3. Think twice: much water conservation in the home is common sense:
o Washing clothes: Use full loads in your washing machine, or if purchasing a new unit, look for water saving features such as half load capability or reduced water consumption.
o Insulate hot water pipes to prevent the loss of heat in your water!
o Use showers instead of baths. Have baths as a treat, a sensual experience to be relished once in a while. Take showers instead, and if you are very keen on water conservation you can share your shower with a friend. On an average, a bath tub uses 100 Gallons of water (more than 350 Litres) during 1 bath.

Even Better, take bucket bath, you can take bath in as less as 5-10 Gallons.
o Collect rainwater. In many parts of the US, the water collected from rain falling on the roof of an average house could supply the water needs of at least one person provided that the water is stored. This collected water can be used for most applications but care should be taken if you suspect any leaching of particles from your roof surface. If this is the case then the water can still be used for washing your car, watering your lawn and garden.
o Car washing: It is possible to wash a car with only one bucket of water. But does it really need washing?
o Garden watering: To save water and to give your plants the maximum benefit, it is best to water during early morning or in the evening. This will cut down on water loss due to evaporation. Avoid sprinklers, which use water indiscriminately, and try to target the water precisely where it is most needed.
4. Reuse your graywater: All the water used in the home, apart from blackwater, can be re-used to some degree. This recycling can be facilitated by installing a graywater reuse system. Water can be collected from five main sources in the home:
oShower
oBath tub
oBathroom sink
oClothes washer
oUtility sink

How to conserve water at your business

There are a wide variety of opportunities for businesses to reduce their water use and expense. Here are some quick ways that involve little or no up-front costs.
•Increase employee awareness of water conservation
Work with all employees to develop methods and procedures that will reduce water use. Evaluate how employees are using water and determine, with their help, more efficient alternatives
•Actually study your water bill each month
Compare the results to the same month of the previous year. This will help you to both identify leaks as they occur and monitor your conservation efforts.
•Check for leaks
A leaking toilet can waste more than 50 gallons of water each day and a dripping faucet or showerhead can waste up to 1,000 gallons per week!
•Install faucet aerators
Inexpensive and simple to install, low-flow faucet aerators can reduce your business’ water consumption as much as 50% and reduce your energy cost of heating the water also by as much as 50%
•Operate cooling towers & boilers according to manufacturers’ specifications
Reduce excessive blow-down. Many cooling towers operate below the suggested levels of total dissolved solids (TDS) unnecessarily. Adjust boiler and cooling tower blow-down rate to maintain TDS at levels recommended by manufacturers’ specifications.
•Discontinue using water to clean paved areas
Instead of hosing down entrances, sidewalks, parking lots and loading docks, sweep or use a blower to clean these areas.
•Wash vehicles only when necessary
If your business operates a fleet of vehicles, do not wash them on a regular schedule; instead wash them only when they are dirty. Consider washing the vehicles at a commercial car wash that recycles the water.
•Review your landscaping practices
First, detect and repair all leaks in your irrigation systems. Make sure the sprinklers are watering the landscaping only – not the street or sidewalk. Water your landscape during the coolest part of the day and install moisture sensors to reduce unnecessary watering. Once you have incorporated these ideas into your work routine, upgrade inefficient equipment and processes.
•Upgrade your irrigation systems
An inefficient irrigation system can cost your business hundreds or even thousands of dollars each month in wasted water. Upgrade your system so that it automatically shuts off when it’s raining, reads real-time ET for accurate irrigation run times and/or incorporates flow sensors that turn the system off in the event of leaks or broken heads.
•Replace air conditioners and refrigerators
If your company’s air conditioners or refrigerators use water-cooled condensers, investigate air-cooled equipment for possible efficiencies.
•Install water-efficient toilets, urinals and faucets
Replacing toilets that use 3.5 gallons or more per flush, and urinals that use 2 gallons or more per flush, can often produce substantial savings. Low-flow faucets are also a sound alternative to those that use 1 gallon or more per minute.
•Switch to efficient ice machines
Air-cooled ice machines are much more cost-effective and efficient than models that use water for cooling. Check to see if your ice machines are water or air-cooled.
•Automate your cooling tower
Cooling towers, located at many large buildings, use water through evaporation and “blow-down.” Rebates are available for modifications to ensure the water blowdown is operated in the most efficient manner possible.
•Reuse process water
Many industrial processes require heated or cooled process water. By reusing process water, your business can lower its water bill as well as its energy expenses.
