Project location: Tehran
Project objective: Renovation of the water distribution network and supportive facilities
Project starting date: August 2011
Project completion date: September 2016
Project duration: 5 years
Abstract:
Behesht-Zahra has known as the public cemetery of Tehran capital city and during recent years the green spaces of the area have been developed significantly. The water distribution networks were operated in 1971 and after more than 4 decades of operation, the water distribution network and transmission pipelines of the site were dramatically damaged and decayed. Moreover, the expansion of the site of Behesht Zahra organization from 150 to 650 hectares caused to face with new problems for water supply. Water resources of the project area include 18 deep and semi-deep wells, aerial reservoirs, and concrete buried reservoirs plus several wells located outside the project area. Water resources of the project area include 18 deep and semi-deep wells, aerial reservoirs, and concrete buried reservoirs plus several wells located outside the project area.
With the aim of renovating the water distribution network and improving the wells, in the first phase of the project, basic studies had done which included: meteorology, geology, availability of water resources, and water supply of the site. Based on the estimation of total water demand (drinkable water and irrigation of green space) Hydraulic designing of drinking water distribution lines had done by using EPANET and WaterGEMS
Construction of buried concrete reservoir, Behesht Zahra Cemetery, Tehran
Project outcome:
Rehabilitation of dried wells, restriction of green space expansion, effective operation of irrigation system and methods, improvement of water discharge control system to tankers, design of raw water networks, and telemetry network design were part of the measures for effective water management of the Organization.
The main physical work of the project includes the following:
- Replacing new water pipelines instead of old pipelines including:
- Transmission lines of water wells to the reservoir with a total length of 12 Km
- Transmission lines of drinkable water with a total length of 51 Km
- Transmission lines and distribution network of raw water with a total length of 60 Km
- Design and construction of 2 concrete buried reservoirs with a total capacity of 120000 M3
- Design and construction of 3 reservoirs with a total capacity of 54000 M3
- Design and construction of 3 pump stations with 288, 250, and 140 L/S respectively
- Renovation and installation of electrical and mechanical equipment
- Building control room for intelligent water management system
