- To study the physical and chemical characteristics of the aquifer planned for Aquifer Storage and Recovery (ASR) techniques in the saline groundwater zone of Tehsil Toba Tek Singh at farmer’s field using resistivity survey meter.
- To investigate the effects of volume, rate and periods of surplus water storage on groundwater quality and lateral and vertical extent of the injected water in the aquifer.
- To monitor the quality of groundwater injected and pumped and evaluate the recovery efficiency and suitability of the aquifer for implementing the ASR concepts by ensuring the farmer’s participation and the Agri. Extension personnel.
Achievements during the period under report
The study area was selected at Chak No. 405/JB, Tehsil Toba Tek Singh, to demonstrate the Aquifer Storage and Recovery (ASR) technology as an approach to recharge the groundwater. As a part of the ASR technology, resistivity survey, in collaboration with the Agricultural Engineering Department, Govt. of Punjab, was conducted and demonstrated to the farmers of the area for its benefits prior to the well drilling. Keeping in view the resistivity survey, an ASR technology and its components regarding water storage pond, dug well, filter, delivery pipe, control valve, volume measuring meter and pump etc. has been designed using the computer software 1X1D (Interpex,USA). Aquifer thickness and groundwater quality and quantity was assessed which is a significant achievement. The benefits of the survey were shown to the farmers of the area regarding proper well design and strainer length installation with respect to the aquifer potential. After preparing the land, points have been marked according to the design measurements The drilling agency (Kisan boring, T.T. Singh) has started their work and a well of 9 ft dia and 20ft depth has been dug. The drilling of the ASR well is in progress.
