About Project

This plan has been among the priorities of Tehran Regional Water Company aiming to recognize pollution risk, pollutant resources releasing into 6 lakes of large dams supplying Tehran Province with drinking water, Amirkabir, Latyan, Lar, Taleqan, Mamloo and Namrood Dams. Threatening factors of these 6 watersheds in terms of biological and microbial, physicochemical and industrial pollution were investigated and finally Risk Management Plan (RMP) was presented. In this study a new risk management method named WRASTIC was modified for Iran Dams risk management studies.

Actual services:
