Water conveyance system ppt. Conveyance of water in case of sources of water supply is river or reservoir and the town is situated at higher level the water will have to be pumped and conveyed through pressure pipes. The purpose of a conveyance system is to drain surface water up to a specific design flow from properties so as to provide protection to property and the environment. Buried pipeline water distribution systems though comparatively more expensive have major advantages over surface water distribution systems comprising of network of field channels. Water conducting system.
Economics of water supply systems. In the open channel water flows with a free water surface i e a surface on which pressure is equal to local atmospheric pressure. After flowing through the intake structure the water must pass through the water conveyance system may be either of closed conduit type as shown in figure1 tunnel off taking from upstream of the river diversion or could be open channels as shown in figure 2. Chapter 7 conveyance of water introduction to conveyance transportation of water to treatment plant or reservoir or distribution through conduits.
For example in a water resources system the analyst must decide which hydro logic basin and water sources dams reservoir and conveyance systems and service areas and water uses to include in the system. Water supply intake structures functions and drawings pipes and conduits for water pipe materials hydraulics of flow in pipes transmission main design laying jointing and testing of pipes drawings appurtenances types and capacity of pumps selection of pumps and pipe materials. The inputs define the flow of resource into the system and the outputs and products from the system. Example of automation and smart water supply systems.
The most common type of water conveyance system is the open channel. Case studies and. Water demand water stress physical water scarcity economic water scarcity 1 1 billion of the poorest people in our world lack the most basic. Capital and operational cost of water supply system.
This chapter contains detailed design criteria methods of analysis and standard details for all components of a conveyance system. If the source is available at higher level than the town it is better to construct the treatment plant near the source and supply the water to the town under gravitational forces only.
