The main objectives of this
project are:
Introduction
the traditional way to dispose of waste
water is cesspit.
the solution is to design sewage
collection system .
Design of water distribution network is
one of the most important
infrastructure action .

• Diameters
• Velocity
• Cover
• Slope
Estimate the cost of the network
• Cost of excavation = 124131.875 NIS
• Cost of Sewer = 379295 NIS
• Cost of manholes = 79500 NIS
• Cost of covers = 68900 NIS.
• Cost of basement concrete = 3205.44
• Cost of base coarse = 39457.6
• Cost of Asphalt = 140920 NIS
