Broad conceptual guidelines of the Tank Reliant Irrigation Area Devel- opment (TRIAD) project and coverage of Districts has been communi- cated in GoMs No.72, I&CAD department, dated 25-05-2011 (refer- ence second cited). The following 8 districts (Table-1), where more than 50% of the net irrigated area (NIA) is fed by tanks and other minor irrigation sources, have been identified for the TRIAD Project. Table-1: TRIAD Project Districts Net Irrigated Region District % MI Area (Acres) Andhra Srikakulam 554,050 61% Vizianagaram 405,171 71% Vishakhapatnam 354,589 67% Rayalaseema Chittoor 435,088 61% Anantapur 323,686 53% Telengana Adilabad 318,251 54% Medak 292,991 91% Ranga Reddy 134,896 93% Total 2,818,722 Note: Includes irrigation potential of ongoing projects, most of which are in the major and medium irrigation sector. Thus, the actual share of tank reliant irriga- tion will be higher than what is indicated in this table.B. Preliminary Project Report (PPR) is to be prepared on the basis of Cat- chment area studies integrating Remote Sensing, Global Positioning System (GPS) and Conventional Surface Hydrology data. C. Considering the long tradition of tank chains and tank reliant irrigation in Chittoor area, pilot studies were taken-up in approximately 50 Sq.Km area of three micro basins in the same district. Pilot study in the Pennar sub-basin by the AP State Remote Sensing Application Centre (APSRAC), yielded the following data (Table-2) for Preliminary Project Report (PPR) preparation work.

Earlier Government had issued orders in GO Rt No.1157,I&CAD(MI4) dated 14-06-2009 for preparation of Tank Memoirs, in respect of erstwhile Panchayat Raj tanks, mostly with 10-40 hectares (25-100 acres) ayacut. More than 64 data elements grouped under four catego- ries namely (i) Location details (ii) Hydrological particulars (iii) Stan- dards of the tank (iv) Other relevant information are being collected. Tank Memoirs are permanent records useful for taking up restoration and repair works as and when needed. An amount of Rs.24.804 crores was sanctioned for preparation of the memoirs by outsourcing the task to private firms. The CE-MI has informed that 16 agencies are engaged for preparation of Tank Memoirs. These agencies are also gathering (a) Video recordings of the Ayacut viewed from the tank bund, (b) Video recording of tank bed and foreshore viewed from the tank bund, and (c) Photographs of tank structures namely sluice, surplus weir and bund etc. There are 20,868 tanks spread over 22 districts for which tank memoir preparation work has been entrusted. Out of this 10,817 tanks fall in the 8 TRIAD project districts. By now tank memoirs have been prepared for 14,798 tanks including 6,325 tanks in TRIAD Project dis- tricts. B. Subsequently, the DG APSRAC proposed development of a Tank In- formation System (TIS) using high resolution satelite remote sensing, geographical information system (GIS), and geographical positioning system (GPS) data. An amount of Rs598.65 lakhs has been sanctioned in GOMs139 I&CAD(MIG) dated 16-09-2011 (reference third cited), for development of TIS while integrating the tank memoir preparation work sanctioned earlier. C. Synergies exist between the Tank Memoir preparation, the Tank Infor- mation System and the TRIAD project preparation works. According- ly, the APSRAC will be able to generate the following information that can feed into preparation of preliminary project reports for the TRIAD project.1. Satelite data & Survey of India Topo sheets. 2. Delineation of catchment area of tanks and cascades, including drainage, using 1:25000 scale, and where this is not available, using 1:50000 scale SI topo sheets. 3. Preparation of land cover and land use map of the area. 4. Preparation of slope map using SI topo sheets. 5. Eyeballing of SI topo sheets, group discussion and brainstorming to identify po- tential new tank sites and new cascades. D. However, during follow-up discussions, APSRAC officers have indi- cated that the TIS cost estimate submitted by them did not include the cost of preparation of tank memoir for the remaining MI tanks. The re- maining tanks include mostly, larger MI tanks. Substantive parts of tank memoirs for these tanks would be readily available in the con- cerned Irrigation Divisions. Additional data, consistent with modern concept of tank memoirs, such as GPS coordinates, etc. will have to be gathered. Hence, APSRAC officers have been asked, vide para 2 (b) & (d) of reference fourth cited, to group the Tank Memoir data elements and estimate additional cost for gathering of field data to complete the tank information system. E. The DG APSRAC has, in the mean while informed that, Tank Memoir data elements that can be gathered from records & documents have since been identified in consultation with the CE-MI. These data ele- ments mostly identify the tanks. APSRAC will incorporate these identi- fying data into the Tank Information System. However, these identify- ing data elements constitute a small part of the Step-1 of TRIAD PPR. This does not significantly reduce the unit cost for TRIAD step-1. Hence, it will be desirable to ask the PPR preparation agencies to gather complete information required for step-1 of TRIAD PPR. 3.Administrative Sanction for TRIAD - Preliminary Project Report Preparation: A. Government, after careful consideration, hereby accord the administra- tive approval for Rs.2493.82 lakhs (Rupees twenty four crores, ninety three lakhs, and eighty two thousand only) for development / preparation of Preliminary Project Report ( PPR) for Tank Reliant Irrigated Area De- velopment (TRIAD) Project for 8 districts as per the cost estimate given intable-3 below, based on the unit costs derived from the pilot studies done by APSRAC in Pennar sub-basin of Chittoor district.
