Specifications

Specification 221100, delete paragraph 3.2 H. and replace with the following:

H. Water and Non-Potable/Sewer Line Crossings

1. Parallel installation requirements.

a. Potable mains in relation to non-potable mains.

1) Greater than ten (10) feet separation: no additional requirements.

2) Ten (10) feet to six (6) feet separation: separate trenches, with the bottom of the potable main above the top of the non-potable main, and non-potable main constructed with potable water class pipe.

3) Less than six (6) feet separation: design engineer to submit data to the Department for review and approval showing that this installation will protect public health and the environment, non-potable main to be constructed of potable water class pipe, and with the bottom of the potable main above the top of the non-potable main.

4) Non-potable mains are prohibited from being located in the same trench as potable mains.

5) Pressure wastewater mains or other pressurized mains or lines containing non-potable fluids shall be no closer horizontally than ten (10) feet from potable mains.

b. New potable services in relation to non-potable services, new potable services in relation to non-potable mains, and new non-potable services in relation to potable mains.

1) Greater than six (6) feet separation: no additional requirements based on separation distance.

2) Less than six (6) feet separation: design engineer to submit data that this installation will protect public health and the environment and non-potable service constructed with potable water class pipe.

3) New potable services are prohibited from being located in the same trench as non-potable mains or non-potable services.

2. Requirements for potable water mains or services crossing non-potable water mains or services.

a. If there is eighteen (18) inches or more vertical separation with the potable water pipeline above the non-potable pipeline, then the potable pipeline joints must be as far as possible from the non-potable water pipeline.

b. If there is eighteen (18) inches or more vertical separation with the potable water pipeline below the non-potable pipeline, then the potable pipeline joints must be as far as possible from the non-potable pipeline, and the non-potable pipeline must be supported through the crossing to prevent settling.

c. Less than eighteen (18) inches vertical separation:

1) Potable pipeline joint to be as far as possible from the non-potable pipeline; and either:

(a) Non-potable pipeline constructed with potable water class pipe for a minimum of ten

(10) feet either side of potable pipeline with a single twenty (20) foot section of potable water class pipe centered on the crossing; or

(b) Sleeve non-potable or potable pipeline with potable water class pipe for ten (10) feet either side of crossing. Use of hydraulic cementitious materials such as concrete, controlled density fill, and concrete slurry encasement is not allowed as a substitute for sleeving.

2) If potable pipeline is below non-potable pipeline, the non-potable pipeline must also be supported through the crossing to prevent settling.

d. Pressure wastewater mains or other pressurized mains or lines containing non-potable fluids shall be no closer vertically than eighteen (18) inches from potable mains.

Specification 221100, delete paragraph 3.6 A.2 and replace with the following:

2. Use purging and disinfecting procedure described by authorities having jurisdiction or, if method is not prescribed by authorities having jurisdiction, use procedure described in AWWA Standard C652-11 for the storage tank, AWWA C651, or as described below. If there are inconsistencies between the requirements use the more stringent standard.

Specification 221100, add the following to paragraph 3.6 A.2.h:

The contractor shall take two biological samples on one day and then take two additional samples a minimum of 24 hours apart from the initial samples. The samples shall all be determined to be bacteria absent by an Idaho certified lab prior to public operation.

Specification 332100, add the following paragraph 2.6 B:

B. Pitless shall be the type marked approved by the National Sanitation Foundation or Pitless Adapter Division of the Water Systems Council. The adapter shall be designed, constructed and installed to be watertight including the cap, cover, casing extension and other attachments. Adapters with a two (2) inch or smaller diameter shall be provided with a swing joint outside the pitless unit to reduce strain, deformation, and possible leakage of the pitless seal caused by settling soils in the trench. The orientation of the swing joints shall be such that any settling that occurs will tighten the threads.

Specification 332100, paragraph 3.1 G.1 delete the wording, “Idaho Department of Environmental Quality” and replace with the following:

Idaho Department of Water Resources

Specification 332100, paragraph 3.1 I.6.a delete the wording, “15 ppm” and replace with the following:

Specification 332100, paragraph 3.2 B.2 delete the first sentence and replace with the following:

Comply with AWWA A100 and well abandonment procedure of authority having jurisdiction, Idaho Department of Water Resources.

Specification 332100, paragraph 3.5 add Section E.:

E. The following data shall be provided in a report.

1. Static water level in the well prior to test pumping.

2. Well yield in gpm and duration of the pump test, including a discussion of any discrepancy between the desired well yield and the yield observed during the test.

3. Water level in the well recorded at regular intervals during pumping.

4. Profile of water level recovery from the pumping level projected at the original static water level.

5. Depth at which the test pump was positioned in the well.

6. Test pump capacity and head characteristics.

7. Sand production data.

8. Results of analysis based on the drawdown and recovery test pertaining to aquifer properties, long term sustained yield, and boundary conditions affecting drawdown.

Drawings

Sheet 3 of 14, Site Overview:

The waterline from the Rock Creek road (indicated to replace 2-inch valve) shall be replaced with 4-inch line from this location to the connection to the new line to the pumphouse. The schedule has been revised to reflect this change. The 2-inch valve replacement shall be deleted. The upsizing is needed to ensure a 2.5 fps flushing ability through the 6-inch line.

Sheet 6 of 14, Trench Cross Section Detail, delete “24” Design Width” and replace with the following:

Pipe Diameter plus 24” Design Width

Sheet 7 of 14, Well Installation Notes add note 12 which state the following:

Upper annual seal must be reconstructed to original design specifications after pitless unit placement.

Sheet 8 of 14, Well Installation Notes change the location of the check valve (item 18) upstream of the hose bibb (item 21).
