about 515.87 MLD. The financial, administrative and technical deficiencies of the
supply system have led to the deterioration of the water supply in the city. The demand
of water has considerably increased due to the improvement in standard of living vis-àvis
growth. The increasing pressure on the ground water resources, has led to an
alarming situation. Though, the rate of declining of ground water is different in different
localities, however, the average is 0.82 m per year for the entire city.
In the present RWH model, the RS and GIS methodology has been successfully
incorporated to visualize the suitability of different classes for best use of rain water. In
total, nine zones have been indentified for land utilization purpose. These are based on
the suitability index according to their use in agriculture, water body and settlement
mask with least proportion designated as poor or very poor class. The zones 1 to 7
represent excellent to satisfactory in RWH model this indicate that these sectors have to
be primarily used for the rain water harvesting practices. This includes the agricultural
land with settlement masks and natural water bodies. The 8 and 9 th class designated as
poor and very poor zones are salt affected or wasteland. The present RWH model can
be used for utilization of rainwater for recharging ground water. In addition it is
sustainability that counts in the end and the present model has been stipulated for the
betterment of land use of the given area in future.

The day is not for of when we will have to look for an alternative to our mother
earth for our survival. The pace with which we are draining our resources the day is not
for of when certain of our most valuable natural resources such as ores, minerals will
disappear. So sooner the better we realize and start conserving, preserving and ensure
optimal utilization so as to avoid the wastage. At the same time we should start looking
for possible synthetic route for our valuable ores in the laboratory which will be helpful
in controlling environmental degradation due to mining and excavation. We have
ventured to synthesize in the laboratory minerals of the alunite series in the laboratory.
Alunite has potential value as a source of both aluminium and potassium compounds.
Alunite and related jarosites are of the mineralogical interest on account of many types
of isomorphous replacements shown by them. A clearer understanding of the structure
of these minerals may pave the way in aiding mineralogist and geologist in study of the
genetic significance of the aluminium hydroxide minerals and possible of related clay
minerals. Lattice parameters and densities of the synthesized minerals as well as
