  • Investigation for according clearance for LI schemes.
  • Survey for classifications of soils for canal construction.
  • Investigation for industries/mines for environmental clearance.
  • Study feasibility and effect of sand mining on groundwater regime.
  • Technical advise for implementation of WALTA.
  • Preparation of reports, notes, periodicals and maps for dissemination of data.
  • Creating awareness on groundwater management at grass root level.
  • Special studies on impact of artificial recharge structures.
Q.4: What is the total availability of ground water resources in Andhra Pradesh?
Ans: Estimated annual available ground water resources is 34.70 Billion Cubic Meter (BCM) and utilization for all purposes is 14.10 BCM. Stage of groundwater development in the State is 41%. In Non-Command area it is 59% where as in Command area it is 21%. ( As per GEC-2007 estimations)
Q.5: What is stage of ground water development?
Ans: The stage of ground water is ratio of Annual Ground Water Draft and Net Annual Ground Water Availability in percentage.
Q.6: What is the Groundwater Assessment Unit in Andhra Pradesh?
Ans: Assessment unit is a watershed with an area from 100 to 300 Sq.Kms Andhra Pradesh is divided in to 1229 micro watersheds for the assessment of groundwater resources.
Q.7: What are over-exploited, critical and semi critical units?
The ground water resources are assessed in units i.e villages/mandals/watersheds. These assessment units are categorized for ground water development based on two criteria -a) stage of ground water development, and b) long-term of pre and post monsoon water levels. The long term ground water level trends are computed generally for the period of 10 years. The significant rate of water level decline are taken between 10 to 20 cm per year depending upon the local hydrogeological conditions. There are four categories, namely -'Safe' areas which have ground water potential for development; 'Semi-critical' areas where cautious groundwater development is recommended; 'Critical' areas; and 'Over-exploited' areas, where there should be intensive monitoring and evaluation and future ground development be linked with water conservation measures. The details of criteria for categorization of assessment units are given in following Table –
S.No Stage of ground water dev.(%) Long term decline Categorised
1 <= 70% No No Safe
YES/NO NO/YES To be reassessed
YES YES To be reassessed
2 > 70% and <= 90% No No Safe
YES/NO NO/YES SEMI-CRITICAL
YES YES To be reassessed
3 90% and <= 100% No No To be reassessed
YES/NO NO/YES SEMI-CRITICAL
YES YES CRITICAL
4 >100% NO NO To be reassessed
YES/NO NO/YES O E
YES YES O E
Q 8: What is need for rain water harvesting and artificial recharge of ground water?
Ans: The need for adopting rain water harvesting is –
  • To overcome the inadequacy of surface water to meet our demands.
  • To arrest decline in ground water levels.
  • To enhance availability of ground water at specific place and time and utilize rain water for sustainable development.
  • To increase infiltration of rainwater in the subsoil which has decreased drastically in urban areas due to paving of open area.
  • To improve ground water quality by dilution.
  • To increase agriculture production.
  • To improve ecology of the area by increase in vegetation cover etc.
Q 9: What is the role of Ground Water Department under APWALTA?
Ans: Registration of all the existing Rigs in the Andhra Pradesh State.
  • Notification of areas for implementing the Act.
  • Providing the list of areas for Notification.
  • Selection of well sites before drilling.
  • Providing technical opinion in case of disputes.
  • Joint inspection prior to leasing of sand reaches for mining.
Q 10: What is the procedure for sinking of new wells?
  • On payment of Rs.100/- towards application fee to Mandal Revenue Officer, the farmer will apply permission for new well in Form – 2 along with a demand draft for
    Rs.1000/- in the name of concerned District Deputy Director, Ground Water Department, towards groundwater survey charges.
  • Only after clearance from APTRANSCO and Spacing norms satisfied by MRO, then the MRO will forward the application to the concerned District Deputy Director Ground Water Department to conduct investigations for groundwater feasibility.
  • After groundwater investigations are completed, the feasibility report will be forwarded to the MRO for according permission in Form 3.
  • Q 11: Who are the District/Divisional/Mandal Authrorities?
    Ans: District Authority -- The District Collector / Ex-officio Chairman of APWALTA Divisional Authority – The Revenue Divisional Officer / Ex-officio Chairman of APWALTA Mandal Authority -- The Mandal Revenue Officer / Ex-officio Chairman of APWALTA The Authority to register the wells ---Village Secretaries at Gram Panchayaths and Town planning Department at Municipalities & Urban areas. Authority to register the Rigs in the District -- Concerned Deputy Director, Ground Water Department.
    Q 12: What is the role of A.P.Ground Water Department in Sand Mining?
  • The District Ground Water Department shall take up joint inspection along with officials of Mines & Geology Department and other concerned line departments whenever cases are referred by concerned District Level Sand Committee to study the impact of sand mining in an area and shall give its recommendations.
  • Sand mining is prohibited in notified Over Exploited ground water micro-basins except for local use in the villages of higher order streams like Godavari, Krishna and Pennar etc.
  • Permission to quarry sand shall not be granted within 500 m from any ground water extraction structure either for irrigation or for drinking water purposes.
