RAIN WATER HARVESTING AND ITS CONTRIBUTION ON HOUSEHOLD

RAIN WATER HARVESTING AND ITS CONTRIBUTION ON HOUSEHOLD 

Rain water harvesting is basically a mode of preserving the water which comes from rain and instead of letting it wasted it is saved in dams and other places like large water containers so it will use in the time of non-rainy seasons for livestock irrigation as well as for drinking water. 
Basically rain water harvesting was introduce in around 3rd BC in places namely Baluchistan presently in Pakistan, Iran & Afghanistan and in  Kutch presently in INDIA and in ancient Tamil Nadu rain water harvesting was done by Chola kings  

ADVANTAGES 

  • It is the most cheapest way of harvesting  
  • It needs no filtration for landscape irrigation  
  • It can reduce water bills  
  • It reduces the probability of flood in low level regions  


Quality 

  • There is no doubt that we should analyze the water before using it for some special purposes or using it as for drinking water. But there is no doubt that the quality of rain water collected is highly better then surface water  

System setup 

  • Rain water system is get setup in highly minimal cost and it is highly cheaper than other mode of harvesting with lots of advantages. but it is should remember in mind before setting up the setup that the tank in which water has to be stored should be large enough to store the quantity with having  capability to maintain adequate flow of water 

Present day 

China brazil are on the top list countries who are using this system very efficiently  and getting day by day advance in making such tanks and canals to store more & more water because they know it really well that they can’t get cheaper irrigation water than that there are many other countries are also in queue namely  
  • India  
  • United-kingdom 
  • Sri Lanka  
  • Israel 

Contribution on Income 

Rain water harvesting is one of the oldest mode of preserving fresh water and cheaper too.  A country with having this rain water irrigation system in a good manner no doubt can save lots of its money reserves and can expand of other  things like education health development sectors etc. and it is proven that it is the best way because if it was not than why countries with such great GDP are using this method of preserving fresh water namely China brazil India srilanka Israel & united kingdom so other countries and specially developing countries should focus to build or advance this rain water harvesting system so they can lift up their nation and can secure handy money

Software Development & Fundamentals Microsoft Certification 98-361 TEST BANKS LESSON 2

Lesson 2: Introduction to Object-Oriented Programming 1. You are developing code for a method that calculates the discount for the items sold. You name the method CalculateDiscount . The method defines a variable, percentValue of the type double . You need to make sure that percentValue is accessible only within the CalculateDiscount method. What access modifier should you use when defining the percentValue variable? a) private b) protected c) internal d) public Answer: a Difficulty: Medium Section Reference: Understanding Access Modifiers The private modifier restricts the access to the class in which the member was defined. The protected modifier restricts the access to the containing class and to any class derived directly or indirectly from the containing class. The internal modifier restricts the access to the code in the same assembly. The public modifier does not restrict access. 2. You are developing code that defines an InitFields method. Th...
