Your tap water is cleaner than you think
Cities waste water for luxury! Most institutions and households in the cities are supplied with soft water. They blindly install Reverse Osmosis (RO) systems, which waste more water than they purify- almost in the ration of 60:40.
All housing and office buildings have single pipe connections,which supply drinking water even for flushing toilets. Not every one uses the modern commode which has dual mode of flushing. At one flush, more than 10 liters of precious drinking water is lost! At ZED we use Low-flow fixtures that curtail the net water demand by as much as 30,000 liters a year of fresh water saved. Grey and black water segregation at source and treatment is also done separately.
Standby mode is like a leaky tap
2700 million units of electricity is lost annually through appliances in standby mode. Put off your TV sets,set-top boxes,and personal computers. Rural poor has very small standby consumption,followed by urban slums. Urban middle class has the highest standby consumption.
Recycling wasted electricity from lifts
Just like metals and plastics,energy can also be recycled. Elevators and escalators fitted with regenerative drive technology allow the recovery of the energy used to move them up and down. This energy is then converted for use elsewhere in the building;in elevators,as much as 50% of the total energy used can be recovered this way.
