4. A VIEW OF TIGHRA RESERVOIR

5. INTRODUCTION:
• Tighra reservoir was constructed in the year
1929 on Sank river to fulfill the water supply
of the Gwalior.
• So, It is the life line of Gwalior city.
• It is situated about 20 km west of Gwalior
city.
• Besides supplying drinking water, the
reservoir is also used to culture fishes by the
fisheries department and for irrigation
purpose.

6. OBJECT OF THE TOPIC

7. PARAMETERS:
• TEMPERATURE (OC)
• TRANSPARENCY (cm)
• TURBIDITY (NTU)
• CONDUCTIVITY (μS/cm)
• pH
• DISSOLVED OXYGEN (DO) (mg/lit)
• TOTAL HARDNESS (mg/lit)
• CHLORIDE (mg/lit)
• ALKALINITY (mg/lit)
• NITRATES (mg/lit)
• PHOSPHATE (mg/lit)

8. OBSERVATIONS:
Physico-chemical analysis of the water of
reservoir was carried out during November
2010 to October 2011 to assess the water
quality of the reservoir.

20. CONCLUSIONS:
• The desirable pH of drinking water is 7 to 8.5 (WHO,
1984). The average pH of the Tighra reservoir varied
from 6.85 to 7.72 .
• It means that the water of Tighra reservoir is suitable
for drinking purpose and is under the standard range.
• The total hardness of Tighra reservoir was between
66.25mg/lit and 137 mg/lit which was under
permissible limits.
• This indicates that the water of Tighra reservoir is
suitable for drinking purpose.Optimum hardness for
fish culture has been reported to be around 150 mg/lit
(Das1996). Accordingly, the water of Tighra is suitable
for fish culture.

21. • Chloride concentration ranged between 11.3 mg/lit
and 40.7 mg/lit.
• Low chloride contents indicate that the water is not
polluted and is safe for drinking purpose.
• On the basis of the present study of physico-chemical,
it can be concluded that the water of
Tighra Reservoir is safe for drinking purposes.
• In addition, the study indicates that the water is
quite suitable for fish culture and by adopting new
and better management and scientific approach the
production of the fish can be augmented.
