WATER ANALYSIS OF TIGHRA RESERVOIR

  1. 1. WATER QUALITY ANALYSIS OF TIGHRA RESERVOIR, GWALIOR, (M.P.) By Dr DUSHYANT KUMAR SHARMA Govt. Model Science College, Gwalior
  2. 2. SATELLITE IMAGE OF TIGHRA RESERVOIR
  3. 3. A VIEW OF TIGHRA RESERVOIR
  4. 4. A VIEW OF TIGHRA RESERVOIR
  5. 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.

  7. 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. 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. 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. 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.
