  1. WATER AUDIT

  2. Water Availability • Water is a prime natural resource • Amount of fresh water available is nearly constant. • Total Available water in AP 108.00 BCM • Usable amount of water in AP 78 .00 BCM • Current Utilisation in AP 65.169BCM • Projected demand by 2020-25 113.00 BCM

  3. Water Scenario Increasing population. unpredictable monsoons. Over exploitation of Ground Water. Increasing competition among sectors. Impact of climatic change. Deterioration of water quality.

  4. Present deficiencies in Water Management • Low water use efficiency. • Distribution losses. • Poor operational maintenance and Management. • Low returns on investment. • Soil salinity and water logging. • Tail end problems.

  5. Strategy • Effective water management minimise use of water and to achieve higher productivity. • Present level of efficiency 1 Cusec of water 80-100 acres of paddy. Could be increased to 130 acres. • Diversification of cropping pattern. • Irrigation efficiency – improve technology. • Conservation of water through minimising transmission losses. • Capacity building of the staff of the Irrigation Dept. • Participatory Irrigation management.

  6. What is Water Auditing? • Checking water use against planning. • Amount of water available for supply. • Water delivered to users. • Water losses – leakages, un accounted losses. • Suggestions and improvements to plug leakages.

  7. Benefits of Water Audit • Proper Documentation • Minimising leakages • Improve performance – system & financial • Improved reliability of supply system • Efficient use of existing supplies • Better safe guard to public health and property

  8. Water Audit It is the need of the hour to have “more crop per drop”. Water auditing is a systematic & scientific examination of water accounts of the irrigation projects Comprehensive water accounting method devised, with water accounting at project level as well as at last manageable unit i.e., section office level. The water use efficiency arrived is compared with the targeted one. National Water Commission also recommended Water Audit and Benching Marking in all Projects.

  9. Main Objectives To compare the water use efficiency with the targeted one for further improving the performance. To check the water losses for saving and conserving water To identify the best management practices To generate healthy competition among various projects/units.

  10. Pilot projects selected Godavari Delta System. Krishna Delta System Nagarjuna Sagar Project Sri Ram Sagar Project. Somasila Project K.C Canal RDS

  11. Indicators selected for Water Audit Availability of water in the reservoirs Percentage of actual evaporation to max. live storage Percentage of evaporation to gross utilisation Water use pattern Water use efficiency Percentage of projected and actual non-irrigation use Percentage of water remained unutilised to max. live storage

  12. Formats have been finalized after discussions with Engineers Proforma – 1 – Water Indent. Proforma – 2 – Water releases Proforma – 3 – Water utilization Proforma – 4 – Rainfall and evaporation Proforma – 5 – Staffing pattern & O&M Expn. Proforma – 6 – Annual water account Benchmarking Proforma Information for the previous five years and for the current year is being collected for the pilot projects
