NKUSIP (Package I - Dharwad)Tranche I Sub-Projects in Haveri CMCInitial Environmental Examinationsurface water body. It is said that the lake was once the main source of waterfor the town. Dodda Halla (a stream) is the major natural stream flowing alongthe southern and southeastern boundary of the town. This stream carriesoverflows of Haggere kere and also carries runoff from surrounding areas.60. The Dodda Halla runs dry for almost complete year except during for a shortduration of monsoon. The stream at present carries wastewater from the Haveritown; this water is mainly used for irrigation purpose. Almost entire area in thetown drains into the stream. This stream joins River Varada in the northeasternside of the town at about 12 km from the town. Given the low flow, extractionfor the irrigation and also the dry weather condition of the town, thewastewater never meets the river. The proposed sewage treatment plant (STP)is located near this stream and the treated sewage is proposed to be disposedoff into the stream.5. Groundwater61. Sizable population in Haveri depends on groundwater for the daily waterneeds. However, the main source of water supply for the town is from theRivers, Varada and Tungabhadra, flowing considerably far from the town. Inthe unserved areas of the town, the population is dependent on groundwatersources. The groundwater table is the area is deep fluctuating between 30 mand 50 m below ground level.Table 13.

The following table shows the groundwater characteristics in the area. Some ofthe monitored parameters such as TDS, chlorine exceed desirable limitsspecified under Indian Standard (IS) 10500, but are under permissible limits. Aspresented in Table 14, the quality of water has improved from monsoon to postmonsoon season. This is primarily because of high extractions during summerKUIDFC29WSAPL
