269 Villages In Maharashtra Will Face Water Scarcity By Summer 2022

If any Third World War breaks out, it will be fought on the issue of drinking water. In India also there are disputes about sharing of river waters.

Maharashtra is not an exception to it. We are at the threshold of next monsoon.

It will be appropriate to look at the Drinking water Scarcity Report for 2021-2022 prepared by the Commissioner, Maharashtra Groundwater Survey & Development Commissionerate, Pune.

Groundwater level mainly depends on rainfall. In Maharashtra there are 5 main river valleys. They are divided in1531 watersheds. 3920 observation wells are chosen for the Survey.

Regional availability of groundwater depends on rainfall, geographical condition, geological structure & use of groundwater. The state is divided in three categories, heavy rainfall area, eternal rainy region & drought prone area.

The 28% region of the state is a rocky and highly dissected plateau. Konkan, western ghats and other hilly areas receive less rainfall. 44% area is moderately dissected plateau that is middle level in groundwater level.

Remaining 28% region is undissected plateau and or valley fill which has a good groundwater level. These 5 main river valleys have been divided into 1531 Watersheds.

Each watershed is further classified into 3 categories: 1 Runoff Zone=86153sq km-28% 2 RechargeZone=135383sqkm-44% 3 Storage Zone=86153 sq km-28%

82% of the area consists of basalt (Igneous rock) which has 1 to 3% water retention capacity. 10% land has metamorphic rocks that can retain 1 to 3% groundwater. Remaining 8% area comprises sedimentary rocks which can retain 5 to 10% groundwater.

The factors that cause low level of groundwater & water scarcity are: 1. Spatial & temporal variation and Dry Spells 2. Very high use of groundwater for irrigation 3. Use of Borewells 4. Traditional method of use of flowing water that causes wastage of water 5. Absence of water planning & its management.

District wise No. of Talukas & Villages having groundwater level depletion more than 1 m in September, 2021 as compared to last 5 years average September water levels
