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 65.169
  BCM
• Projected demand by 2020-25 113.00 BCM

Water Scenario

1. Increasing population.
2. unpredictable monsoons.
3. Over exploitation of Ground Water.
4. Increasing competition among sectors.
5. Impact of climatic change.

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.

8
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.

9
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.

10
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

11
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.

12

• 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.

13

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

14

• 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

15

• 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 OM Expn.
• Proforma 6 Annual water account
• Benchmarking Proforma
• Information for the previous five years and for
• the current year is being collected for the
