Greatest problem in water conservation is to reduce the amount of evaporation. Evaporation is a process by which a large amount of water evaporate in the form of water vapours (gaseous form)

Water-saving technology for the home includes:

• Low-flush toilets and composting toilets. These have a dramatic impact in the developed world, as conventional western toilets use large volumes of water. 
  
• Rainwater harvesting high-efficiency clothes washers weather-based irrigation controllers garden hose nozzles that shut off water when it is not being used, instead of letting a hose run. Low flow taps in wash basins. 
• Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.
  

Water heavily may  result in root rot due to water logging preventing the roots from respiring aerobically. When roots respire anerobically alcohol produced as a byproduct results in root rot. Watering has to be done based on the season and the water requirement of the plant

Natural resources are of two types, exhaustible and non-exhaustible. Exhaustible resources are those natural resources that are available in limited quantity. Examples include coal, natural gas, petroleum. Non-exhaustible resources are those natural resources that are available in abundance. Renewable resources are those which can be recycled or replenished. The solar energy is renewable and non-exhaustible source. Water is a renewable but exhaustible resource. It may exhaust one day if used without any concern.
