Block map of Durg


Durg with an area of 870800 ha is one of the important agricultural, mining and industrial districts of Central India. Only about 11.4 % of area encompasses reserved and protected forest land. The district is divided into 11 tehsils and 12 blocks covering 8708 inhabited villages. Durg is the district headquarters. The total population of the district is 28,01,757 (2001) census. An area of 54300 ha is the net area sown and 21300 ha. area is double cropped in the district Out of which only 11648 ha of land (5.259 % of net irrigated area) is irrigated by ground water.

The district has subtropical climate characterized by hot summer and monsoon rainfall followed by dry and cold winter season. The normal average rainfall of the district is 1270 m.m. The annual temperature varies from 42.2 % (summer) to 11c (winter). The relative humidity varies from 86% (rainy season) to 36% (winter).


Major part of the district is drained by Seonath, Hamp, Kharr and Tendula river and their tributaries. Major surface water sources in the district is Tendula canal/ system and the total irrigated area is 100703 ha. Geologically, 87 % of the total geographical area of the district is covered by sedimentary formations of Chhattisgarh Super group comprising gypsiferous sale, Chandi limestone, Gunderdehi shale, Charmuria limestone, Chandarpur sandstone and Archaean granite gneisses.

Ground water occurs under phreatic and semi confined to confined conditions in the intergrannular pore spaces in the shallow weathered rocks and in the fractured systems at deeper levels respectively. The general range of ground water levels in the phreatic aquifer varies from 1.76 to 11.02 m.b.g.l. in premonsoon period, while in post-monsoon period it varies from 0.68 to 7.28 m.b.g.l. Long term (Decadal) trend analysis of water level reveals 19% of the wells in pre monsoon and 4.5% of the wells in post monsoon period show significant (20cm/yr) fall of water levels.

Under the exploration programme, the Central Ground Water Board, CGWB has drilled 29 boreholes in the Durg district to assess the aquifer systems and their potential. The data from the boreholes has revealed that deeper aquifer systems exist down to depth of 300 m.b.g.l. potential fracture zones occur at shallow depth of 30 to 60 m. The discharge of borewells varies from 4.5 to 6 Lps. In the limestone, the depth of drilling ranged from 114 m to 300m with discharge varying from 20 to 45 Lps. The depth of weathering, occurrence of solution cavities in limestone and Dolomite and fractures in the sandstone are the main controlling factors for the potential aquifers.

The ground water in the district is mainly developed by dug wells and dug cum bore wells for irrigation. These structures tap groundwater down to a depth of 6 to 20 mbgl. The borewells generally range in depth 45 to 60 mbgl. Bore wells fitted with hand pumps are used for the rural drinking supply requirements of the village community.


The quality of ground water in the district is generally suitable for both drinking and irrigation and is within permissible limits as per the Indian Standards for water use. The excess Iron in the range of 1 to 20 ppm at places is reported from most of the villages by PHED Govt. of Chhattisgarh. during their random survey. The sampled wells are mostly bore wells in the depth range of 15 to to 50m.

Ground Water Resources

Ground water resource figures presented below are as per the estimations carried out jointly by CGWB,Govt. of India and Ground Water Survey Circle, Govt. of Chhattisgarh. The figures pertain to the year 2004.Out of the 12 blocks in the district, 6 (Balod, Gurur, Patan, Saja, Durg, Dhamdha) have been categorised as semi critical and rest have been categorised as safe from ground water development point of view.
