In many regions, traditional systems of water harvesting and management have been used effectively for centuries. Here are some common methods:
Rainwater Harvesting
: Collecting rainwater from rooftops or catchment areas and storing it in tanks or underground pits is a common practice. This method helps in replenishing groundwater and provides an additional water source.
Check Dams
: Small barriers built across streams or rivers to slow down the flow of water and allow it to seep into the ground. This helps in recharging groundwater levels and preventing soil erosion.
Stepwells
: Ancient structures built with a series of steps leading down to a water source. Stepwells were designed to store water during dry seasons and provide easy access for villagers.
Percolation Pits
: Pits dug into the ground to collect and allow rainwater to slowly percolate into the soil, which helps in groundwater recharge.
Zing
: Traditional irrigation channels used to direct water from rivers or streams to fields. These channels ensure that water is evenly distributed across agricultural lands.
2. Compare the above system with the probable systems in hilly/ mountainous areas or plains or plateau regions.
Solution
The traditional systems of water harvesting and management vary significantly based on the geographical features of the region:
Hilly/Mountainous Areas
:
Stream Diversion
: In these regions, streams and rivers are often diverted using channels or canals to distribute water for irrigation and domestic use. This method leverages the natural flow of water downhill.
Glacial Rivers
: Water is commonly sourced from rivers originating from glaciers. These rivers provide a steady supply of water, which is essential for agriculture and daily life.
Plains
:
Lakes and Rivers
: In plains, natural water sources like lakes and rivers are the primary sources of water. These sources are often large and easily accessible.
Groundwater Harvesting
: Borewells are extensively used to access groundwater for both irrigation and domestic purposes. This method is crucial in areas where surface water might be insufficient or seasonal.
Plateau Regions
:
Water Storage Structures
: In plateau regions, traditional methods include building check dams or bunds to capture and store rainwater. These structures help in managing runoff and recharging groundwater.
Percolation Pits
: Similar to hilly areas, percolation pits are used to enhance groundwater recharge by allowing rainwater to infiltrate into the soil.
3. Find out the source of water in your region/locality. Is water from this source available to all people living in that area?
Solution
In metropolitan cities, the primary source of water is often groundwater, which is extracted through a network of borewells and wells. Some areas may rely on surface water from lakes, rivers, or reservoirs.
While this water is generally distributed throughout the city, availability can vary. In well-developed areas with modern infrastructure, water is usually accessible to most residents.
