06 Feb Assessment of ground water potential, university park, kariavattom.
Well, the Dept of Geology moved to university park, kariavattom by the end of 1968 during Xmas break. It was a big change. Campus was brand new, and so many buildings lined along the newly built roads hostels etc. most of the teachers did not like the new setting. There was only ground water supplied to homes, hostels and academic blocks. There were three bore wells that hardly went beyond a depth of say 125 ft. Keariavattom univ park geologically stood on weathered pc crystallizes coveredd with a veneer of tertiary sedimentary rocks.
The spot where the campus PO stands is on a sheet of bauxite a rock that separated sedimentary rocks from the altered crystallizes. The road to the language block had on its left side exposures of channel fill of baring thickness like three feet occasionally.
The VC quarters stood on a space where the underlying rock is of tertiary age. In fact the road now heading to techno park, had near vc residence a fairly thick exposure of cross beded units and northerly of the road.
So geologically we at kariavattom is wrongly placed for a good we’ll aping an aquifer worth it’s name.
But then, the vc wanted the geology professor to locate a good aquifer in the campus for drinking water. The hod thought it was kind of another burden. Luckily there were two more young lecturers, Chacko John and v narayanaguru Nair. Chacko and I were assigned the task of doing a survey or a reckie to figure out the potential.
We teamed up very well, purchased a rope and other gadgets like topo map, Brenton compass and a ballast weight for use with the rope to measure the water table depth in the several tens of shaft wells in and around the campus.
To our surprise, there was a sub artesian well on the west side national highway about a km from kazhakootam jn. There was a glass framed well log hung in the pumping room. The well went down to a depth of about three hundred feet and was supplying drinking water to aaa good number of people. We copied that information along with subsurface geology,
The sai in school at kazhakootam also depended on the gw for meeting the needs of about four hundred people in their campus. The well log was available. It went through a very thick section of tertiaries and then finally went into the altered basement.
Yet another bore well at kulathoor also was very prolific. That well not only supplied water locally but also supplied water to the hostels of the CET.
With all these details we met mr v c Jacob in the CGWB for a discussion, with the data we had. On his part mr Jacob made a proposal to the TTP, for a twenty feet diameter filter point well to meet the water needs of the company.
We along with mr Jacob arrived at a recommendation to construct a twenty feet diameter filter point well in newly acquired land at kazhakootam, I.e., between the junction and the point where a stream crossed the nh47. Two lay a pipeline to pump water to the campus to a ground level tank and then subsequently from the tank pump water to the three water towers in the campus.
Our hod, prof. Menon couldn’t really appreciate the idea of new land at kazhakootam, new filter point well there with a pumping station and then a dedicated pipe line to the campus etc etc. yet he wrote up a report with such a recommendation and personally presented the same to the vc.
That is interesting. Chacko John is now in the univ of Lusiana , Baton Rouge.
