Abstract
"An investigation on analytical study of water at domestic level
was carried out in the year 1999-2000 in Dharwad city. Four
residential areas viz., Hosayellapur, Gulganjikoppa, Murgamath and
University of Agricultural Sciences Campus, Dharwad were considered.
Survey and laboratory experiment were carried out to know the
consumption pattern of water, chemical composition, bacterial counts
of water and effect of plant materials viz., drumstick seeds, dry amla
and clove on hardness reduction of borewell and open well water. Self
structured questionnaire, EDTA titrimetric method and standard pour
plate method was adopted to collect the data.
The survey indicated that majority (82%) of the selected families
used corporation (Malaprabha) water for all the household activities
and maximum (110.85 It) amount of water was used for bathing. An
average water consumption per day per family was 324.91 litres. Most
of the families (38%) paid minimum of Rs. 45.00 towards water bill.
More than 50 per cent of the families were not facing any problems
related to water supply.
Bore well and open well water from selected residential areas
were collected and analysed for total hardness. It was found that,
hardness of bore well water was more in Hosayellapur (1432.8 mg/lt)
when compared to other locations. Similarly, hardness of open well
water was more in Murgamath area and it was exceeded permissible
limit given by WHO i.e. 200-600 mg/lt. Among the selected plant
materials viz., drumstic seed, dry amla and clove, 0.8 g of dry amla was
found to be good in reducing (16.46%) the hardness of bore well water
after one hour of contact time. Similarly for open well water, 0.8 g of
clove after 12 hr of contact time was found to be effective in reduction
of total hardness. Water treated with dry amla was accepted for its
colour, aroma and appearance. Performance of clove was good in
reducing the bacterial counts of selected water samples."
