Valedictory function was held on 28.7.03 and certificates with course material were distributed to the trainees.
7.2 Participation in Exhibition, Mela, fair etc No exhibition was conducted in the district
8.0 Areas Notified by CGWA/SGWA No area in the district is notified so far.
9. Recommendations Considering the prevailing scenario of the groundwater resources and development the following recommendations are made for the optimum drawl with sustainable development of resources in the area.
1) The dug wells, which penetrate partially the weathered, fractured zones of the aquifers, may be deepened further for the better productivity.
2) Construction of several types of structures like sub surface dykes, percolation tanks, check dam etc has been proposed in the different taluks.
3) A comprehensive programme should be formulated to harvest the rain water through roof top, check dams, surface tanks, bunds and subsurface dykes to use the resources directly from the structures, which in turn to arrest the sub surface flows and augment the groundwater resources.
4) The ground water worthy areas such as topographic lows, valley portions low water level fluctuations zones should be developed with an adequate soil conservation measures to prevent the soil erosions.
5) Constant monitoring of ground water quality should be carried out in the Cauvery and Hemavathi canal command areas to prevent the pollution and related problems. The determination of trace elements and organic compound is done to help in categorizing the quality of water.
6) The ground water in canal command area is found under-developed therefore, it is strongly recommended to prepare an action plan to bring more area under conjunctive use of ground water and surface water irrigation.
7) An additional number of 13667 dug wells and 26092 borewells/dug-cumborewells, constructed would help in tapping the unutilized ground water, an annual average draft of 0.9 ham and 1.1ham can be exploited respectively through dug wells and borewells and keep the area under safer category.
8) Conjunctive use of both Surface and Ground water practiced in the canal command area would improve the quality of ground water, prevent the water logging conditions and availability of canal water to the tail end areas.
9) The ground water development should be allowed only areas, which are catagorised as safe and semi critical with caution.
10) Mass awareness programmes should be conducted for public awareness about the limited availability of ground water resource.
11) Farmers should be educated to grow less water intensive crops and adopt micro irrigation system. Government should provide subsidy such irrigation systems.
12) Artificial recharge structures should be constructed in feasible areas for augmenting ground water resource and to improve ground water quality especially in areas of K.R.Pet, Nagamangala and Malavalli taluks where fluoride problem exists to a limited extent.
13) Sites for bore wells and dug wells should selected with the technical advice from technical qualified persons.
14) Precaution is to be exercised while using pesticides and fertilizer in the command areas of the district as it is vulnerable to ground water contamination.
