Pollution of Latyan Dam in northeastern Tehran can be reduced by 90%, if buildings within the dam’s basin are connected to the urban wastewater network, said an official at the Shemiranat County’s Department of Environment.

The network will help prevent household wastewater from flowing into Jajroud River, the reservoir’s main tributary.

Speaking to ISNA, Bijan Moqimi added that wastewater entering Jajroud River is one of the main sources of pollution of Latyan Dam.

Over the years, a larget number of restaurants have been built along the river, dangerously close to the bank, many of which dispose their waste into the water. However, things are looking up.

“Pollution released into the river by these establishments has declined considerably,” said Moqimi.

“We issued notices and employed other measures, such as unannounced visits and undercover patrols, which seem to have helped.”

Pointing to the structures illegally built on the sides of Jajroud, the official said the Water and Wastewater Company is in charge of protecting the river and is currently “demolishing the illegal constructions” on the river bank.

Latyan Dam is a buttress dam on Jajroud River, located 25 kilometers from Tehran in the south of Lavasan, Shemiranat County. It is one of the main sources of water for Tehran’s metropolitan region supplying 30% of its drinking water.

Apart from Jajroud, the rivers of Kondroud, Afjeh and Barg-e Jahan also flow into Latyan. The reservoir can hold around 245 million cubic meters of wate,r which is used to irrigate 30,000 hectares of farmlands.

However, wastewater disposal and excessive construction in the upstream regions pose a major challenge for the dam. Large masses of construction waste are piled around the reservoir and the influx of vehicles on holidays threatens the region’s ecosystem.
