This shall also be got confirmed by Time v/s Volume Method during commissioning of the plant. The scale shall be adequate to indicate water depth upto 25% overloading over the designed discharge of the plant. Apart from the measuring scale, a simple float operated rate of flow indicator shall be provided over the stilling chamber. The equipment may be of dial type or linear scale type calibrated to read the discharge directly in litres/hour. Rapid Mix Arrangement The above mentioned weir also shall act as a hydraulic rapid (flash) mix device. The lip of the weir shall be minimum 500 mm above the invert of the bottom slab of the channel. This is essential so as to have a minimum free fall of 400 mm on the downstream side of the weir. The free fall of 400 mm to 500 mm on the downstream side of weir shall ensure velocity gradient of 800 to 1000 litres/sec. A mixing basin of 2 to 5 seconds detention time shall be provided on the downstream side of weir at the beginning of mixing channel. A baffle wall with 100 mm to 150 mm height shall be constructed at a distance of 0.75 M to 1.0 M from the mixing weir to give the desired detention time.

FIELD TEST PRESSURES FOR PIPELINE

After laying and jointing any pipe line, the pipe line must be pressure tested to ensure that pipes and joints are strong enough to withstand the maximum pressure likely to be developed under working condition. In this respect G.O.I. Manual on Water Supply and Treatment, (IIIrd Edition March, 1991) describes the field test pressures to be imposed on pipe lines. In this respect, for different types of pipes, concerned paras from this manual are as follows : Sr. No.

Type of Pipe Para No. Remarks

1. M.S. pipes Para 6.5.2 As per para 6.4.4.2 2. Ductile Iron pipes Para 6.5.2 As per para 6.4.4.2 3. Concrete pipes Para 6.8.3 As per para 6.4.4.2 4. Pre-stressed pipes Para 6.9.3 As per para 6.4.4.2 5. PVC pipes Para 6.10.5 As per para 6.4.4.2 6. CI pipes Para 6.4.4.2 As per para 6.4.4.2 Thus, for above 6 types of pipes, field test pressure is as per para 6.4.4.2. As per this paragraph., the field test pressure to be imposed should be not less than the maximum of the following : a) 1.5 times the maximum sustained operating pressure. b) 1.5 times the maximum static pressure in the pipe line. c) Sum of maximum sustained operating pressure and the maximum surge pressure d) Sum of maximum pipe line static pressure and the maximum surge pressure, subject to a

maximum equal to the work test pressure for any pipe fittings incorporated. Here, it is to be noted specifically that, while determining the class of pipe, along with other conditions, aspect of above field hydraulic test pressure should also be considered. Para 6.7.1 of the Manual refers to A.C. pipes lines and there is no specific mention about field hydraulic test pressure and it is not clear whether it should be as per para 6.4.4.2 or not. Hence there were doubts in the minds of some field officers about field hydraulic test pressure of A.C. pipe line. It is also seen that the idea of operating pressure and working pressure is also not very clear in the field. Hence these points are clarified as under :

( 100 )


About working pressure it is clarified that working / operating pressure is the maximum sustained internal pressure, excluding the one coming in abnormal conditions such as surge (water hammer), to which the pipe line may be subjected to, when in use. When we consider A.C. pipe lines as Gravity Mains, then maximum internal pressure occurs when water in tank is at the F.S.L. (fully supply level or full tank level) and the Sluice Valve, located at lowest level in the section under consideration, is in closed position. In such case, the static head i.e. the difference between the F.S.L. of source and lowest invert level of pipe line in that section, is the maximum head in that section. Thus, here, as far as test pressure and class of pipe is concerned, maximum operating pressure is the static pressure. When we refer to I.S. 6530 / 1972, the field hydraulic test pressure for A.C. pipe line should be 1.5 times the operating pressure and as explained above, considering the definition of operating pressure, A.C. pipe Gravity Main should be tested for 1.5 times the operating pressure i.e. for 1.5 times the static pressure. In other words, this is the condition given in G.O.I. Manual para 6.4.4.2 for gravity mains. For deciding the class of A.C. Gravity Main, maximum static pressure shall not exceed 50% of pressure defining class of pipe (Ref.- App. 6.4). All the field tests should be carried out for the pressure as clarified above only. Since we are not using A.C. pressure pipes for large / long Rising Mains, no mention of A.C. pipe Rising Mains is made above.

18.2 Shaft supporting a water tank must be designed as given under the para "Stresses in Circular supporting Walls" at page 84 of the book "Concrete Water Towers Bunkers Silos and other elevated structures" by Gray and Manning (5th edition), published by Cement and Concrete Association. The vertical load causes direct compression. Under wind load, the wall act as a vertical cantilever of hollow circular section and has to resist bending moment and shearing forces. In addition to main stresses, caused by the wall acting as a hollow circular vertical cantilever, the wind flowing on one face tends to flatten that face, distorting the circle into an oval. Horizontal reinforcement to resist a bending moment M = + 0.035 PD2 producing tension on the inside face and a moment M = - 0.031 PD2 causing tension on the outside face, where P = Unit wind pressure in KN/M and D=c/c diameter of shaft in metres.

The reinforcement arrived as above should be provided on both, inside and outside faces.

However minimum horizontal reinforcement in the shaft shall be 0.3% of the gross concrete area provided. In case of towers in high seismic zones (i.e. Zone - IV and V ) minimum horizontal reinforcement shall be 0.4% of the gross concrete area provided.

Shaft shall be checked for combined axial load and bending due to wind or seismic loads and

shall satisfy the provisions of IS 456-2000 in tank full and tank empty conditions. Horizontal construction joints in shaft shall be as minimum as possible. Age factor for increasing strength shall not be considered. Shaft should be checked for tensile stress in worst condition for combination of axial tension on

bending axis due to wind or seismic load for tank full and tank empty conditions. On account to minor inaccuracies in construction of the shaft the allowable direct compressive

stress shall be reduced by multiplying with a factor of 0.85. On account of buckling reduction factor if any shall be multiplied by the factor of 0.85. For the calculation of direct compressive stress the contribution of steel shall be neglected.

For buckling calculations reduced value of modules of elasticity due to creep shall be maximum

0.4 times its value as per IS 456-2000. At the plinth panel 50 mm thick M-150 grade shall be provided. Rectification of Defective Members If it is found that certain members are defective and are found giving acoustical or vibrational

disturbances even though these may be structurally sound, rectification of such members should be done by the contractor free of charge and to the satisfaction of Engineer-In-Charge.

Provided always that in the event of the Contractor depositing a lumpsum by way of security deposit as contemplated at (A) above, then and in such case, if the sum so deposited shall not amount to 2 percent of the total estimated cost of the work, it shall be lawful for MJP at the time of making any payment to the Contractor for work done under the contract to make-up the full amount 2 percent by deducting sufficient sum from every such payment as last aforesaid until the full amount of the security deposit is made-up. All compensation or other sums of money payable by the Contractor to MJP under terms of this contract may be deducted from or paid by the sale of sufficient part of his security deposit or from the interest arising therefrom, or from any sums which may be due or may become due by MJP to the Contractor under any other contract or transaction of any nature on any account whatsoever and in the event of his security deposit being reduced by reason of any such deduction or sale as aforesaid, the Contractor shall within ten days thereafter, make good in cash or Government securities endorsed as aforesaid any sum or sums which may have been deducted from or raised by sale of his security deposit or any part thereof. The security deposit referred to, when paid in cash may at the cost of the depositor, be converted into interest bearing securities provided that the depositor has expressly desired this in writing.

The amount of security deposit lodged by a Contractor shall be refunded along with the payment of the final bill, if the date upto which the Contractor has agreed to maintain the work in good order is over. If such date is not over, only 90% amount of security deposit shall be refunded along with the payment of the final bill. The amount of security deposit retained by the MJP shall be released after expiry of period upto which the Contractor has agreed to maintain the work in good order is over. In the event of the Contractor failing or neglecting to complete rectification work within the period upto which the Contractor has agreed to maintain the work in good order, then subject to provision of Clauses 17 and 20 thereof the amount of security deposit retained by MJP shall be adjusted towards the excess cost incurred by the MJP on rectification work.
