Section 178-12-011 - INSTALLATION OF PUMPS AND PUMPING EQUIPMENT

12-011.01B1 Care must be taken so that all tools used in the removal of pumps and pumping equipment are disinfected periodically, or as needed. Disinfection solution must be equivalent to 50 parts per million chlorine solution (See Table 2). It is not permissible to lay the drop pipe, pump, pumping equipment, or wire on the ground.

12-011.01B2 When a pump for a potable well is installed or repaired the well must be disinfected with a disinfectant solution equivalent to 50 ppm chlorine solution (See Table 2), unless specifically waived in writing by the landowner. The waiver must be worded in accordance with Attachment 1, "Waiver of Disinfection." The water well contractor/pump installation contractor must supply the landowner with an informational brochure that tells the owner why s/he should test his/her water and what the results mean.

1. Offset Location: The suction pipe must be encased in a sleeve from the basement or well pit wall to the well. In the instance of a packer jet system, the pressured pipeline can serve as a sleeve for the suction line.

2. Priming Port must be located higher than the discharge of the pump. Discharge of the priming port may be controlled with a shut off valve. Potable water must be used for priming the pump. Priming valve must be sealed when not in use to prevent contamination from accumulating above the valve.

1. Bear the Pitless Adapter Standard (PAS) stamp of approval of the Water Systems Council.

2. Be factory assembled and ready for installation from a point of connection with the well casing to the unit cap or cover.

3. Be a threaded, welded, screwed, or flanged gasket compression connection to the well casing.

4. Be of watertight construction throughout, except for any required vent.

5. Be made of steel through the frost zone and be compatible with the casing.

6. Have a field connection to the lateral discharge from the pitless unit of threaded, flanged, or mechanical joint connection.

7. Terminate at least 12 inches above final ground elevation. Where a water well needs to be located in an area of high traffic and physical damage to the pitless unit is probable, the contractor must finish off the water well even with the grade of the surrounding land surface and protect it by terminating it in a pitless unit covered by a watertight flush mount cover capable of withstanding high vehicle traffic conditions. In all cases where the top of the pitless unit is enclosed in a watertight flush mount vault, the vent opening must be sealed and all electrical conduit fittings must be watertight. If the entrance of the electrical conduit is below ground level, the opening around the wire must be sealed. (See Figure 12)

8. Provide:

12-011.03D1 Above ground discharge piping must:

12-011.03D2 Underground Discharge Piping must be equipped with a curb stop valve and schedule 80 plastic or metal riser within one foot of the discharge, and be in compliance with 178 NAC 12-011.01.

1. Sample point must terminate no less than 12 inches above the floor of the basement, well pit, or pump house floor.

2. A primary sample point must not be located down flow from any filter, trap, or conditioning equipment. A secondary sample point may be located down flow from a filter, trap, or conditioning equipment to verify the proper operation of such equipment.

1. Pressurized, if used (hydro-pneumatic or captive-air design)

2. Non Pressurized, if used (reservoirs, cisterns, and standpipes)
