Abstract

The Jajrood River originates from the Alborz Mountains north of Tehran, mounts Shemshak and Johnson, and flows towards southwest. After joining the Garmabdar and the Routeh rivers, it turns towards southeast and when joining the Big and the Small Lavasanat rivers, it pours in Latyan Dam. About 295 mm 3/y of the water of Latyan Dam is sent to Tehran's 4th water treatment plant in Tehranpars. The rest is released as riparian right for agricultural uses in Varamin Plain. The Jajrood River serves many villages on the trans-passing course and receives their entire wastewater because the region’s hills, the lack of facilities for wastewater treatment, and the problem of solid waste disposal on the river banks.The Jajrood River supplies the drinking water of about 2,600,000 people in the east of Tehran through Latyan Dam. That is why the management of its water quality seems to have a very high priority.During a period of 6 months in 2004, samples were taken from 18 villages before the water flowed in and after it flowed out of them. Then, the important factors of water quality of the samples were compared with those of the previous years and the standards. Changes in the amounts of certain parameters such as BOD, COD, and TDS were easily observed after the river passed through every village. Tests proved that the water would get polluted after passing through villages. It became clear that the sources of pollution were domestic sewage and leakages from fruit gardens as well as partially domestic solid wastes dumped into river banks. In the end, offensive and defensive methods of water quality management are recommended.
