Frequently Asked Questions
Q1: What are the different sources of water?
A1: Different sources of water can be classified into two major categories – Surface source and Sub surface sources or underground sources
Some of the examples of both sources are given below
Surface source examples
- Stream, rivers
- Ponds, lakes
- Storage reservoirs
- Oceans
Subsurface source examples
- Wells and tube wells
- Springs
- Infiltration wells
Q2: What are the factors which affect per capita demand?
A2: Factors which affect per capita demand include,
- City size – Compared to the small towns or rural places, per capita demand of big cities is large as they have sewered houses
- Small and big scale Industries
- Climate conditions
- Economic condition, lifestyle and habit of people
- Water quality
- Pressure in the distribution system
- Water work administration’s efficiency
- Water cost
- Metering and charging method policy of water – It could be either on the basis of meter reading or certain fixed monthly rate
