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
water scenario

Water Scenario

Increasing population.

unpredictable monsoons.

Over exploitation of Ground Water.

Increasing competition among sectors.

Impact of climatic change.

Deterioration of water quality.

present deficiencies in water management
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.
  • 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.
what is water auditing
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.
benefits of water audit
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

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.


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.


Pilot projects selected

Godavari Delta System.

Krishna Delta System

Nagarjuna Sagar Project

Sri Ram Sagar Project.

Somasila Project

K.C Canal



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


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
