Four inch black steel pipe (used as extensions to the screens) shall be extra heavy. Four inch screens, 30 slot, shall be wit.wound, E.A. Johnson or egual, 5 foot in length and fitted with bail plug. III. Construction Methods Wells are to be constructed following steps: by rotary drilling in the Drilling of 10 inch open hole to a depth of 49 feet. During this stage of the work, clay mud may be added to the drilling fluid, but the quantity of mud used must be kept to the minimum necessary. Setting of 6 inch casing in the center of the open hole and placing of a temporary plug in its bottom. Placing of the Portland cement grout encasement. Grout must be installed from the bottom of casing upwards, until the annular space is filled to the surface. e Following placing of grout, no work is to be performed for at least 48 hours so that the grout may be allowed to set undisturbed. ® The temporary plug shall then be drilled out and the hole deepened to receive the 4 inch diameter well screen. No drilling mud shall be used during this stage of work. The 4 inch well screen, 3 foot pipe extension, centered in the well. with its bail plug and shall then be placed and The Contractor shall then develop the well by pumping to waste at a rate of 40 gallons per minute or more until the water pumped clears of sand in less than 5 minutes after start of pumping.
