Hint: 1) From ancient times, people were very well aware of the ways to harvest water naturally.
2) They had inside and out information on precipitation systems, soil types and wide going procedures to reap water, groundwater, waterway water and rising water.
3) Direct-pumped, Direct Gravity, Indirect Gravity are types of water harvesting systems.

Complete Answer:
As of late, multipurpose projects and huge dams have gone under incredible investigation and scrutiny. Many thought Water harvesting frameworks was a reasonable other option, both socio-financially and naturally.
Thus, water harvesting system is taken as a better alternative to dams because,
(I) Like dams, it does not displace local people.
(ii) It also does not cause environmental problems like decrease in flora and fauna.
(iii) During the rainy season, excess water is released from dams, which induces floods or creates the flood situation, which is definitely not in the case of water harvesting systems.
(iv) The local people are not profited from big dams, it is the landlords, capital farmers, industrialists and the urban centres who are getting benefits.
(v) In the water harvesting system, common people use the stored water for personal use and in agricultural fields.
And also, the water harvested can be used for multiple domestic uses considering the quality of water like- washing clothes, drinking, in vegetation etc.

Note: 1) Supplanting city and well water with caught water for finishing productively utilizes this significant asset, diminishes individual water bills, and diminishes the general interest on open water supplies.
2) People of the federal government related with the water supply planning processes have determined the current amounts of available surface and groundwater supplies will not be able to meet future water demand.
