TENDER PROJECT FOR THE CASABLANCA WASTE WATER TREATMENT PLANT OUTFALL (MOROCCO)
- Start Date / End Date: 2011/2012
- Place: CASABLANCA (MARRUECOS)
- Scope: Tender Project
The outfall tender project was designed. All of the alternatives proposed replacing the two base solution pipelines with a single larger-diameter pipeline with better hydraulic performance and the corresponding savings in cost and completion time.
The characteristics common to all of the alternatives:• Material: HA tunnel and the rest in PE100.• Length of pipe jacking: 1,021 m• Total length of the pipe (HA+PE): 2,200 m (option 0), 2,500 m (option 1) and 3,000 m (option 2).• Flow rate: 11 m3/s
The characteristics of each alternative:• Alternative 1: ID = 1,966 mm. High pressure• Alternative 2: ID = 2,200 mm.• Alternative 3: ID = 2,200 mm. High pressure
The high pressure solutions were resolved with a specific sandwiched metal layer design compatible with the pipe jacking tunnel.
On the other hand, a complete marine climate study was conducted.
