B.            Store material in a safe manner on project site.

 

3.02        DRILLING

 

 

A.            Well drilling shall be by rotary, reverse-rotary, or cable tool method.  Drilling equipment shall be designed for well drilling and provide positive assurance of a straight, plumb well, Well drilling debris shall be removed from site on a weekly basis and disposed of on an approved site.

 

3.03        SETTING CASING PIPE

 

A             Steel Casing Pipe.

1.               Steel casing pipe shall be welded together as it is installed.  Welds shall be continuous and water tight and conform to the requirements of AWWA C206.  Casing pipes shall be installed plumb and aligned.  Well casing guides shall hold casing in true position during installation and grouting.

2.               Well installer shall make all field welds in accordance with AWS Standard D5.2.  Joints shall be single V-butt type, continuous around pipe.

 

3.04        GROUTING

 

A.            Grout space between casing pipes and outside of drilled hole in accordance with AWWA A100.

 

B.            Allow grout to cure at least 72 hours for Type I portland cement or 36 hours for Type Ill portland cement before further work is performed on well.

 

C.            Grout shall be placed in one continuous operation.  All grout shall be pumped through a grouting shoe at bottom of casing or by use of a tremie pipe and may only be discontinued when grout completely fills void between casing pipe and drilled hole at top of pipe.  Grout shall be a minimum thickness of 2-inches on all sides of the casing pipe.

 

D.            Temporary casing pipe not meeting specifications for permanent casing shall be pulled during grouting.

 

3.05        PROTECT WELL

 

A.            Well hole shall be protected at all times from intrusion of foreign material or surface water.

 

3.06        WELL DEVELOPMENT

 

A.            The well shall be developed by high-pressure air to develop a sand free well when pumped at design rate stipulated herein.

 

B.            If sand free water (less than 5 mg/I sand content) at the design pumping rate is not obtained following development, the contractor shall redevelop the well until the design flow, and sand free condition are obtained.

 

3.07        TEST PUMPING

 

A.            After well has been developed, cleaned out, and depth accurately measured, well shall be test pumped for an estimated 24 hours.

 

B.            Test pump shall be capable of pumping to discharge at the ground surface at a rate of at least 1000 gpm with pumping level 400 feet below ground, but with satisfactory throttling devices so that discharge may be reduced to 750 gpm.  Pumping unit shall have ample power, controls and appurtenances and shall be capable of operating for 24 hours without interruption.

 

 

C.            Flow of water and depth of water in well shall be measured during test pumping

 

D.            Yield and draw down tests (in accordance with Iowa Design Standards) shall be conducted during a continuous test pumping period of at least 24 hours or until stabilized draw down has been maintained for at least 6 hours when pumping at maximum constant rate.

 

E.             Records of the following shall be maintained.  Test pump capacity and head characteristics, static water level, depth of test pump setting, and time of starting and ending each test cycle.

 

F.             Recordings and graphic evaluation of pumping rate, pumping water level and draw down at intervals of 15 minutes or less for first 2 hours, then at intervals of 1 hour or less until 3 hours after conclusion of test pumping shall be taken_ Recordings of well water recovery rates and levels shall be taken at sufficient intervals to allow graphing of recovery curve.

 

G.            Water pumped shall be disposed in a manner preventing damage to private and public property.

 

3.08        DRILLING LOG

 

A.            An accurate log of drilling operations including top and bottom depths of each stratum penetrated shall be maintained.  Samples of materials from each 5’ of drilling and change in formation shall be delivered to Iowa Geological Survey.  At conclusion of drilling, a copy of log showing thickness and classification of each formation shall be provided to the Iowa Geological Survey and to the Iowa Department of Natural Resources.

 

3.09        PLUMBNESS AND ALIGNMENT TESTS

 

A.            After casings have been set to their final location and before grouting, alignment and plumbness tests shall be performed as required in AWWA Standard No.  A100-84, Section 8 supplemented and amended as follows:

1.             Additional plumbness and alignment tests may be required at such intermediate depths or on final completion of well as required.

2.             Plumbness and alignment of well shall be tested for total length of casing.  Plumb or dummy shall move freely throughout length of casing.

3.             Well variance from vertical shall not exceed 213 inside diameter of casing tested per 100’ of depth.

 

B.            If casing meets requirements for plumbness and alignment, well shall be completed.
