The sewers are generally designed as open channels except when it is specially required to design them as conduits carrying sewage under pressure as in the case of inverted siphons. Thus various empirical formulae which are used for the design of open channels are used for the design of sewers. The following empirical hydraulic formulae are commonly used for the [...]
Following method is followed for the design of sewers: 1. Zone Formation 2. Sewer Network 3. Sewage Quantity 4. Flow Velocity 5. Sewer Section 6. Grade of Sewers. 1. Zone Formation: The whole town or city in which sewerage system is to be provided is divided into different zones. The layout of sewers is plotted along the roads, and the [...]
