Basic Objectives Reservoir

The purpose of storing water is to meet balancing requirements and plannedshut-downs. The balancing volume is required to cater for peak outflows whilea constant (or variable) inlet flow is being received. Water needs will usuallyvary between morning and evening. If clean water is unavailable, then theinstallation must be capable of supplying water processing a huge need,especially at peak time (peak hour demand reached 1.27 times the averagedaily requirement). For the possibility that water processing installation shallhave a capacity of about 2 time of the average daily requirement, if notavailable reservoir. With a reservoir (reservoir) is adequate, then the watertreated and distributed only by the amount of the distribution network inaccordance with the needs of the daily average

Volume Reservoir

A. Services ReservoirVolume reservoir services or services reservoir is determined by

The maximum volume of water that must be accommodated atthe minimum water usage plus the volume of water that must beprovided during hours of peak flux fluctuations due to waterconsumption in its service area and the period of reservoir filling.

The water supply for the city fire department in accordance withexisting regulations for the local Fire Department.

The need for special water, draining the reservoir, parks andspecial events.

B. Balancing reservoir

Effective reservoir volume balance or the balance is determined bythe balance reservoir outflow and inflow of water in the reservoirduring the use of the service area. System filling reservoir and pumpsystem can be gravity.Water supply to consumers conducted by gravity.

Effective reservoir volume calculation method:1) The tabulation , By way of tabulation, effective volume is the

largest positive gap amount (m3) and the biggest difference isnegative (m3) between fluctuations in water use and supply water tothe reservoir. The results of calculation of the cumulative value arecreated in table form.2) Method of the curveEffective volume obtained from the largest percentage of theaccumulated surplus plus the accumulated deficit of water use wateruse to the greatest accumulation of runoff water into the reservoir

(where the drainage of water into the reservoir for 24 hours).3) The percentage ofEffective volume was set at a percentage of the maximum waterdemand per day at least 15%. Determination in this way depends onthe habits of the city is concerned, because it must be based on

experience.

The design of the reservoirs themselves for the design of coveredservice reservoirs for the storage of potable drinking water. Essentiallyboth reservoirs are large concrete storage tanks. The common designfeatures on both reservoirs which will site below ground level, can besummarized as follows:

Concrete base, walls and fully enclosed roof;

Internal dividing wall to allow for draining of half of each reservoirfor future repair and/or inspection;

Pipe links from the Inlet House to deliver newly treated water intothe reservoirs;

Pipe links to the Outfall House where water is distributed throughthe system to the customers.
