heating water evaporates and sugar is left behind in the container.Q.3. Explain water supply system in towns diagrammatically, also tell which separating methodsare adopted ? |
| Answer» <p>water supply systemorwater supply networkis a system of engineeredhydrologicandhydrauliccomponents which providewater supply. A water supply system typically includes:</p><p>Adrainage basin(seewater purification - sources of drinking water).</p><p>Araw watercollection point (above or below ground) where the water accumulates, such as alake, ariver, orgroundwaterfrom anunderground aquifer. Raw water may be transferred using uncovered ground-levelaqueducts, coveredtunnelsor undergroundwater pipesto water purification facilities.</p><p>Water purificationfacilities. Treated water is transferred usingwater pipes(usually underground).</p><p>Water storage facilities such asreservoirs,water tanks, orwater towers. Smaller water systems may store the water incisternsorpressure vessels. Tall buildings may also need to store water locally in pressure vessels in order for the water to reach the upper floors.</p><p>Additional water pressurizing components such aspumping stationsmay need to be situated at the outlet of underground or above ground reservoirs or cisterns (if gravity flow is impractical).</p><p>A pipe network for distribution of water to the consumers (which may be private houses or industrial, commercial or institution establishments) and other usage points (such asfire hydrants).</p><p>Connections to thesewers(underground pipes, or abovegroundditchesin some developing countries) are generally found downstream of the water consumers, but the sewer system is considered to be a separate system, rather than part of the water supply system.</p><p>Water supply networks are often run bypublic utilitiesof thewater industry.</p> | |
