Water Distribution Systems Distribution Reservoirs. Water Distribution Systems. The purpose of distribution system is to deliver water to consumer with appropriate quality, quantity and pressure. Distribution system is used to describe collectively the facilities used to supply water from its source to the point of usage. Requirements of Good Distribution System.
Layouts of Distribution Network. The distribution pipes are generally laid below the road pavements, and as such their layouts generally follow the layouts of roads. There are, in general, four different types of pipe networks; any one of which either singly or in combinations, can be used for a particular place.
They are:. Distribution Reservoirs. Distribution reservoirs, also called service reservoirs, are the storage reservoirs, which store the treated water for supplying water during emergencies such as during fires, repairs, etc. Functions of Distribution Reservoirs:. Location and Height of Distribution Reservoirs:. Types of Reservoirs. Storage Capacity of Distribution Reservoirs.
The total storage capacity of a distribution reservoir is the summation of:. The total reservoir storage can finally be worked out by adding all the three storages. It should be capable of supplying the requisite amount of water during fire fighting. All the distribution pipes should be preferably laid one metre away or above the sewer lines. It should be fairly water-tight as to keep losses due to leakage to the minimum. Sign in to your account.
To my understanding, in English, when one talks about reservoirs and storage tanks they're having the following in mind:. Reservoirs Reservoirs are nodes that represent an infinite external source or sink of water to the network. They are used to model such things as lakes, rivers, groundwater aquifers, and tie-ins to other systems. Reservoirs can also serve as water quality source points. The primary input properties for a reservoir are its hydraulic head equal to the water surface elevation if the reservoir is not under pressure and its initial quality for water quality analysis.
Because a reservoir is a boundary point to a network, its head and water quality cannot be affected by what happens within the network. Therefore it has no computed output properties. However its head can be made to vary with time by assigning a time pattern to it see Time Patterns below.
Tanks Tanks are nodes with storage capacity, where the volume of stored water can vary with time during a simulation. Tanks are required to operate within their minimum and maximum levels. EPANET stops outflow if a tank is at its minimum level and stops inflow if it is at its maximum level.
Tanks can also serve as water quality source points. How does this sound to you? The text was updated successfully, but these errors were encountered:. Skip to content.
