Studies of first and second phase of designing green space irrigation networks by raw water in district 7 of Tehran Client: District 7 of Tehran Municipality

CStudies of first and second phase of designing green space irrigation networks by raw water in district 7 of Tehran has been granted to Jamab Consulting Engineers Co. in order to develop the existing network based on the use of modern irrigation systems (under pressure) and to design a sustainable system.
Technical summary of plan is as follows:
o Area: 1500 hectares
o Area of green space with regard to its development: 126 hectares
o Water resources used, including wells and aqueducts in the region
o Anticipated water resources with long-term view: withdrawals from upstream surface sources (Zargandeh watercourse)
o Designing gated diversion weir on the Zargandeh channels and dewatering with capacity of required discharge and construction of settling basin for physical water treatment
o Length of water pipeline from the source to the region is about 15.5 km and distribution network in the region is about 24 km
o Area of plan is designed in three pressure zones and attitude of gravitational-pressurized irrigation. Then the current water supply system by pumping will be out of service and whole system will be pressurized gravity irrigation. Pressure tanks, balanced pressure zones two separate sites with a capacity of 1,000 cubic meters each and layout has been designed.
o Pressure reducing tanks and balancing two units at have been designed at pressure zones separation point with a capacity of 1000 cubic meters.
