SUBMITTALS

1.0 GENERAL

Submittals covered by these requirements include manufacturers' information, shop drawings, test procedures, test results, samples, requests for substitutions, and miscellaneous work- related submittals. Submittals shall also include, but not be limited to, all product data sheets, product information, fabricated items, mechanical, electrical and electronic equipment and systems, materials, reinforcing steel, fabricated items, and piping and conduit details. The Contractor shall furnish all drawings, specifications, descriptive data, certificates, samples, tests, methods, schedules, and manufacturer's installation and other instructions as specifically required in the contract documents to demonstrate fully that the materials and equipment to be furnished and the methods of work comply with the provisions and intent of the contract documents.

2.0 CONTRACTOR'S RESPONSIBILITIES

The Contractor shall be responsible for the accuracy and completeness of the information contained in each submittal and shall assure that the material, equipment or method of work shall be as described in the submittal. The Contractor shall verify that all features of all products conform to the specified requirements. Submittal documents shall be clearly edited to indicate only those items, models, or series of equipment, which are being submitted for review. All extraneous materials shall be crossed out or otherwise obliterated. The Contractor shall ensure that there is no conflict with other submittals and notify the Construction Manager in each case where his submittal may affect the work of another contractor or the Owner. The Contractor shall coordinate submittals among his subcontractors and suppliers including those submittals.

The Contractor shall coordinate submittals with the work so that work will not be delayed. Contractor shall coordinate and schedule different categories of submittals, so that one will not be delayed for lack of coordination with another. No extension of time will be allowed because of failure to properly schedule submittals. The Contractor shall not proceed with work related to a submittal until the submittal process is complete. This requires that submittals for review and comment shall be returned to the Contractor stamped "No Exceptions Taken" or "Make Corrections Noted."

The Contractor shall certify on each submittal document that he has reviewed the submittal, verified field conditions, and complied with the contract documents.

The Contractor may authorize in writing a material or equipment supplier to deal directly with the Construction Manager or with the Owner with regard to a submittal. These dealings shall be limited to contract interpretations to clarify and expedite the work.

01300-1 3.0 CATEGORIES OF SUBMITTALS

A. GENERAL:

Submittals fall into two general categories; submittals for review and comment, and submittals which are primarily for information only. Submittals which are for information only are generally specified as PRODUCT DATA in Part 2 of applicable specification sections.

At the beginning of work, the Construction Manager will furnish the Contractor lists of those submittals specified in the project manual. Two separate lists will be provided: submittals for review and comment and product data (submittals) for information only.

B. SUBMITTALS FOR REVIEW AND COMMENT:

All submittals except where specified to be submitted as product data for information only shall be submitted by the Contractor to the Construction Manager for review and comment.

C. SUBMITTALS (PRODUCT DATA) FOR INFORMATION ONLY:

Where specified, the Contractor shall furnish submittals (product data) to the Construction Manager for Information only. Submittal requirements for operation and maintenance manuals are included in this category.

4.0 TRANSMITTAL PROCEDURE

A. GENERAL:

Unless otherwise specified, submittals regarding material and equipment shall be accompanied by Transmittal Form 01300-A at the end of this section. A separate form shall be used for each specific item, class of material, equipment, and items specified in separate, discrete sections, for which the submittal is required. Submittal documents common to more than one piece of equipment shall be identified with all the appropriate equipment numbers. Submittals for various items shall be made with a single form when the items taken together constitute a manufacturer's package or are so functionally related that expediency indicates checking or review of the group or package as a whole.

A unique number, sequentially assigned, shall be noted on the transmittal form accompanying each item submitted. Original submittal numbers shall have the following format: “SPECIFICATION NUMBER” - "XXX"; where "XXX" is the sequential number assigned by the Contractor. Resubmittals shall have the following format: "XXX-Y"; where "XXX" is the originally assigned submittal number and "Y" is a sequential letter assigned for resubmittals, i.e., A, B, or C being the 1st, 2nd, and 3rd resubmittals, respectively. Submittal 15050-25B, for example, is the second resubmittal of submittal 25 from specification section 15050.

01300-2 B. DEVIATION FROM CONTRACT:

If the Contractor proposes to provide material, equipment, or method of work which deviates from the project manual, he shall indicate so under "deviations" on the transmittal form accompanying the submittal copies.

C. SUBMITTAL COMPLETENESS:

Submittals which do not have all the information required to be submitted, including deviations, are not acceptable and will be returned without review.

5.0 REVIEW PROCEDURE

A. GENERAL:

Submittals are specified for those features and characteristics of materials, equipment, and methods of operation which can be selected based on the Contractor's judgment of their conformance to the specified requirements. Other features and characteristics are specified in a manner which enables the Contractor to determine acceptable options without submittals. The review procedure is based on the Contractor's guarantee that all features and characteristics not requiring submittals conform as specified. Review shall not extend to means, methods, techniques, sequences or procedures of construction, or to verifying quantities, dimensions, weights or gages, or fabrication processes (except where specifically indicated or required by the project manual) or to safety precautions or programs incident thereto. Review of a separate item, as such, will not indicate approval of the assembly in which the item functions.

When the contract documents require a submittal, the Contractor shall submit the specified information as follows:

1. 3 hard or electronic PDF copies of all submitted information shall be transmitted with submittals for review and comment.

2. Unless otherwise specified, 2 hard or electronic PDF copies of all submitted information shall be transmitted with submittals (Product Data) for information only.

B. SUBMITTALS FOR REVIEW AND COMMENT:

Unless otherwise specified, within 14 calendar days after receipt of a submittal for review and comment, the Construction Manager shall review the submittal and return 1 copies of the marked-up reproducible original noted in 1 above. The reproducible original will be retained by the Construction Manager. The returned submittal shall indicate one of the following actions:

1. If the review indicates that the material, equipment or work method complies with the project manual, submittal copies will be marked "NO

01300-3 EXCEPTIONS TAKEN." In this event, the Contractor may begin to implement the work method or incorporate the material or equipment covered by the submittal.

2. If the review indicates limited corrections are required, copies will be marked "MAKE CORRECTIONS NOTED." The Contractor may begin implementing the work method or incorporating the material and equipment covered by the submittal in accordance with the noted corrections. Where submittal information will be incorporated in O&M data, a corrected copy shall be provided.

3. If the review reveals that the submittal is insufficient or contains incorrect data, copies will be marked "AMEND AND RESUBMIT." Except at his own risk, the Contractor shall not undertake work covered by this submittal until it has been revised, resubmitted and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED."

4. If the review indicates that the material, equipment, or work method does not comply with the project manual, copies of the submittal will be marked "REJECTED - SEE REMARKS." Submittals with deviations which have not been identified clearly may be rejected. Except at his own risk, the Contractor shall not undertake the work covered by such submittals until a new submittal is made and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED."

C. SUBMITTALS (PRODUCT DATA) FOR INFORMATION ONLY:

Such information is not subject to submittal review procedures and shall be provided as part of the work under this contract and its acceptability determined under normal inspection procedures.

6.0 EFFECT OF REVIEW OF CONTRACTOR'S SUBMITTALS

Review of contract drawings, methods of work, or information regarding materials or equipment the Contractor proposes to provide, shall not relieve the Contractor of his responsibility for errors therein and shall not be regarded as an assumption of risks or liability by the Construction Manager or the Owner, or by any officer or employee thereof, and the Contractor shall have no claim under the contract on account of the failure, or partial failure, of the method of work, material, or equipment so reviewed. A mark of "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED" shall mean that the Owner has no objection to the Contractor, upon his own responsibility, using the plan or method of work proposed, or providing the materials or equipment proposed.

PART 3--EXECUTION

3.01 GENERAL

A. CONTROL OF WATER:

The Contractor shall keep excavations reasonably free from water during construction. The static water level shall be drawn down a minimum of 1 foot below the bottom of excavations to maintain the undisturbed state of natural soils and allow the placement of any fill to the specified density. Disposal of water shall not damage property or create a public nuisance. The Contractor shall have on hand pumping equipment and machinery in good working condition for emergencies and shall have workmen available for its operation. Dewatering systems shall operate continuously until backfill has been completed to 1 foot above the normal static groundwater level.

Groundwater shall be controlled to prevent softening of the bottom of excavations, or formation of "quick" conditions. Dewatering systems shall not remove natural soils. The Contractor shall control surface runoff to prevent entry or collection of water in excavations.

02200-4 Release of groundwater to its static level shall be controlled to prevent disturbance of the natural foundation soils or compacted fill and to prevent flotation or movement of structures or pipelines.

B. OVEREXCAVATION:

Where the undisturbed condition of natural soils is inadequate for support of the planned construction, the Construction Manager will direct the Contractor to overexcavate to adequate supporting soils. The excavated space shall be filled to the specified elevation with backfill. The overexcavated space under footings may be filled with concrete. The quantity and placement of such material will be paid for as extra work.

C. SURPLUS MATERIAL:

Unless otherwise specified, surplus excavated material shall be disposed of off site in accordance with applicable ordinances and environmental requirements.

D. HAULING:

When hauling is done over highways or city streets, the loads shall be trimmed and the vehicle shelf areas shall be cleaned after each loading. The loads shall be watered after trimming to eliminate dust.

E. FINISH GRADING:

Finished surfaces shall be smooth, compacted and free from irregularities. The degree of finish shall be that normally obtainable with a blade-grader.

Finished grade shall be as specified by the contours plus or minus 0.10 foot except where a local change in elevation is required to match sidewalks, curbs, manholes and catch basins, or to ensure proper drainage. Allowance for topsoil and grass cover, and subbase and pavement thickness shall be made so that the specified thickness of topsoil can be applied to attain the finished grade.

When the work is an intermediate stage of completion, the lines and grades shall be as specified plus or minus 0.5 foot to provide adequate drainage.

If the soil is to be cultivated or straw is to be incorporated into the surface, rocks larger than 2-1/2 inches in maximum dimension, roots and other debris on the surface of the slope shall be removed and disposed of prior to cultivation or placement of straw.

F. CONTROL OF EROSION:

The Contractor shall maintain earthwork surfaces true and smooth and protected from erosion. Where erosion occurs, the Contractor shall provide fill or shall excavate as necessary to return earthwork surfaces to the grade and finish specified.

02200-5 3.02 CLASSIFICATION OF FILL

Fill material shall be placed in horizontal layers and compacted with power operated tampers, rollers, idlers, or vibratory equipment.

02200-6 have a minimum thickness of bedding material below the barrel of the pipe as specified. Bedding material shall be placed in the bottom of the trench, leveled and compacted. Bell holes shall be excavated at each pipe joint to permit proper inspection and uniform bearing of pipe on bedding material.

After the pipe has been laid to alignment and grade, unless otherwise specified, additional bedding material shall be placed in layers the full width of the trench and compacted up to the specified level. Bedding shall be placed simultaneously on both sides of the pipe, keeping the level of backfill the same on each side. The material shall be carefully placed and compacted around the pipe to ensure that the pipe barrel is completely supported and that no voids or uncompacted areas are left beneath the pipe. Contractor shall use particular care in placing material on the underside of the pipe to prevent lateral movement during backfilling.

2. INITIAL BACKFILL: After pipe has been properly bedded, Contractor shall place and compact initial backfill as specified. Initial backfill, where specified below the springline of the pipe, shall be placed and compacted in accordance with paragraph 02200-3.04 C.1 for additional bedding material.

3. SUBSEQUENT BACKFILL:

a. GENERAL: Backfill material, placement and compaction above the pipe zone shall be as specified. Backfill above the pipe zone shall not commence until pipe zone backfill has been inspected and accepted by the Construction Manager.

b. IMPROVED AREAS: Unless otherwise specified, select granular backfill (Class A or B) shall be used under all paved and unpaved roadways and paved and unpaved roadway shoulders, roadway embankments, and in all public right-of-ways and easements. The trench shall be backfilled to an elevation which will permit the placement of the specified surface or paving. Other surfaces shall be restored, including compaction, to the condition existing prior to construction including restoration of yard areas.

c. UNIMPROVED AREAS: Class C1 backfill shall be used for all trenches in pastureland, cultivated land, undeveloped land, and for other unimproved areas where specified. Class C1 backfill shall not be used in any public right-of-way. Trench operation which meets the requirements of Type C material may be used. The Contractor shall maximize the use of fine-grained materials (e.g., sand, silty sand, sandy silt) as Class C1 backfill.

For Class C1 backfill, the trench above the pipe zone shall be backfilled to within 12 inches of original ground surface. The top 12 inches of soil shall be removed and stored in such a manner that it will not become mixed with unsatisfactory soils. After the trench has been backfilled, the stored topsoil shall be replaced at a uniform depth in its original area compacted to its original condition. The Contractor shall leave the backfilled trench neatly mounded not more than 6 inches above existing grade for the full width of the Class C1 backfill area.

02200-7 3.05 SUBGRADE FOR PAVEMENT

This shall include, but not be limited to, the geomembrane material itself, all field and factory seams, attachment at anchor curb at top of slope, and underwater seals to structures.

B. Cleaning of the Basin Geomembrane Liner:

1. Prior to placement of geomembrane baffles or floating cover panel materials on the existing HDPE geomembrane liner, loose particles shall be removed from the geomembrane liner by blowing with compressed air. Blowing shall be performed with an air compressor and suitable lengths of air hose.

2. Accumulations of loose particles shall be removed with brooms and vacuums.

02778 - 23 3. Cleaning of large areas far in advance of panel placement is not acceptable. The underlying material shall be cleaned no more than 2 days in advance of material deployment. This timeframe may be shortened, as determined by the Construction Manager, under less than ideal weather conditions.

4. The Contractor shall conduct his Work to minimize the movement of fugitive dusts from the site boundaries by using suitable Reasonably Available Control Measures (RACM).

3.02 INSTALLATION

A. Panels:

1. The Contractor shall identify and repair any damage or defects to panels that occurred during shipping, unloading, storage, and installation.

2. Reinforced flexible geomembrane floating cover panels shall be carefully placed on the bottom and slopes of the basin in accordance with approved shop drawings, and in such a manner as to assure minimum handling.

3. During installation of the geomembrane floating cover, the Construction Manager shall have complete authority to order an immediate stoppage of the Work because of inclement weather, the use of improper installation procedures, or any other reason which may result in a defective floating cover installation.

4. Seaming shall keep pace with the placement and spreading of panels such that panels will not be laid out unless they can be seamed the same day.

5. Reinforced flexible geomembrane floating cover panels shall be deployed in sufficient time to allow panels to shrink, as a result of panel stretch during the manufacturing and/or fabrication process, prior to field seaming. The Contractor shall account for the panel stretch during the manufacturing process when ordering panel lengths.

6. Prior to backfilling perimeter anchorage trenches the Contractor shall straighten and pull taut, in both directions to remove wrinkles as much as possible. If seaming equipment lifts the material off the substrate and leaves slack material along the seam, wherever possible the wrinkle so formed shall also be pulled out before backfilling trench or seamed to adjacent panels. The Contractor shall continuously make every effort to remove all wrinkles in the floating cover.

B. Temporary Anchorage:

1. Sandbags shall be used as necessary to hold the geomembrane floating cover material in position during installation in order to protect it from damage or displacement due to wind.

2. During any discontinuity of the Work exceeding 4 hours in length, the leading (unseamed) edges of all panels shall be secured with sandbags at not more than 3 feet on center. The Contractor shall be responsible for

02778 - 24 maintaining closer spacing as necessary to protect the Work during all weather conditions.

3. Sandbags placed on slope shall be tied off at the top of slope to prevent their shifting or sliding down the slope.

4. Bags that are split, torn, or otherwise losing their contents shall immediately be removed from the basin area, and any spillage shall immediately be cleaned up.

C. Heat Seaming:

1. Machine-made heat seams shall be used on all field seams, wherever practical.

2. Machine-made heat seams shall be made using hot air or hot wedge welding equipment. All machine heat seaming equipment shall be equipped with gauges that monitor voltage and temperature.

3. Hand-held heat seaming equipment may be used where machine-made heat seams are not practical and for miscellaneous seaming as approved by the Construction Manager.

4. All seaming shall comply with these Specifications and the Contractor's Quality Assurance Plan.

5. Contact surfaces of geomembrane material to be seamed shall be cleaned with water and wiped dry with a cloth until all foreign matter, dust, dirt, and water has been removed. Only clean, colorfast, lint-free, cotton cloths shall be used in the Work. Cleaning of the contact surfaces shall not be completed more than 10 minutes ahead of seaming. When conditions are adverse to proper workmanship such as high winds, or other conditions increase the probability of dirt or other foreign material being deposited on the contact surfaces, the time between cleaning and seaming shall be reduced as necessary to produce acceptable seams.

6. The Contractor shall follow immediately behind the heat seaming equipment, while the material is still hot from the initial seam, bonding the top edge of the seam. The top edge of the seam shall be “stitched” by manually rolling the seam area with firm pressure with a 2-inch wide roller. Joints where 3 layers of reinforced flexible geomembrane meet shall also be stitched to seal the potential leak path along the edge of the middle layer.

7. In the event a floating cover reinforced flexible geomembrane panel has been laid out and not seamed for a period of 3 days or more, the contact surfaces shall be solvent scoured and buffed to ensure a positive bond at the seam. The scouring procedure shall consist of hand buffing the contact surfaces with stainless steel scouring pads soaked in solvent to effectively penetrate and remove the oxidation layer. This scouring

02778 - 25 procedure shall be applicable to all panel-to-panel seams, patches, and seams for attachment of accessories.

8. Care shall be taken to avoid damaging the existing geomembrane liner with the seaming equipment. The Contractor shall take the necessary precautionary measures to ensure the geomembrane floating cover is not bonded to the underlying existing geomembrane liner during the seaming process.

D. Adhesive Seaming:

1. Adhesive may be used to make seams where heat seaming is impractical and for minor repairs and only in those instances approved by the Construction Manager.

2. Adhesive seaming shall comply with the manufacturer’s written recommendations and procedures and the Contractor’s approved Quality Control Plan.

3. Use of adhesives and solvents shall be in compliance with the applicable regulatory requirements.

4. Contact surfaces of reinforced flexible geomembrane material to be seamed shall be cleaned, abraded, and prepared in accordance with the manufacturer’s written recommendations and procedures.

5. The use and application of adhesive shall be performed in accordance with the manufacturer’s written recommendations and procedures.

6. Care shall be taken to avoid damaging the existing geomembrane liner with the seaming equipment. The Contractor shall take the necessary precautionary measures to ensure the geomembrane floating cover is not bonded to the underlying existing composite geomembrane liner during the seaming process.

E. Joinings:

1. Panels to be joined in the field shall be lapped as shown on the Drawings. After the initial seal of the lap joint has been made, all exposed free edges of the geomembrane floating cover shall be resealed, using hand-held equipment, to eliminate all free edges. The top edge of all seams shall be fully bonded. Loose edges will not be allowed on the top side of the floating cover.

2. Butt joints shall be used only where lap joints are not possible and as approved by the Construction Manager. Butt joints shall be formed using joint cover strips made from the same reinforced flexible geomembrane floating cover material, continuous in length, and as shown on the Drawings. The joint cover strip shall be centered over the butt joint and shall be fully bonded across its entire width. Butt joints shall be installed in accordance with the same procedures for lap joints specified herein.

02778 - 26 3. All seams, field and factory, shall be staggered a minimum of 12 inches to ensure that no more than 3 layers of material meet at a joint.

4. Lap joints that cross rainwater collection troughs made in the field shall be reinforced with a joint cover strip, made from the same reinforced flexible geomembrane floating cover material, as shown on the Drawings.

5. The doubler along the centerline of the rainwater collection trough shall be reinforced flexible geomembrane floating cover material. The doubler shall stop and start each side of the joint cover strips and shall be seamed all around on sides and ends. Care shall be taken to extrude air from beneath the doubler before closing the last seam.

6. Longitudinal seams (field or factory seams) on the floor of the basin and parallel with rainwater collection troughs shall not be permitted within 5 feet from the outermost edge of the rainwater collection trough.

7. Where 3 layers of material occur at a “T” joint (field seams, factory seams, and rollstock splices), care shall be taken to seal the small leak path that would otherwise occur along the edge of the middle layer. The upper layer shall be heated and rolled to conform or “step-down” and seal the leak path. In addition, the area shall be solvent wiped and sealed with a high-solids adhesive and then covered with a 40-mil minimum unreinforced EIA material patch as shown on the Drawings. The center of the patch shall be placed at the intersection of the edges of the top and middle layers of the reinforced flexible geomembrane material.

8. Seam preparation shall be in accordance with the requirements stated herein, the manufacturer’s printed recommendations, and the applicable regulatory requirements.

9. Care shall be taken to avoid fishmouths, wrinkles, pleats, folds, and tucks in seams. Any such defects shall be prevented by tugging on the seam just completed in the opposite direction from which the seam is progressing, during the seaming process. The Contractor’s seaming crew shall give continuous attention to the elimination of all such defects to prevent their occurrence. Regardless of the location or cause of such defects, they shall be slit out far enough from the seam to dissipate the defect. The slit edges shall then be lapped and field seamed. Wherever the lap width is less than 2½ inches, the defect shall be repaired with a joint cover strip made from the same reinforced geomembrane floating cover material.

10. Field seams shall not be made if the ambient temperature or humidity would result in inferior seams.

11.

E. TACK WELDS, CLIPS, AND OTHER ATTACHMENTS:

Nicks, gouges, notches, and depressions in the base metal in the area of the joint shall be repaired before the joint weld is made. Tack welds, clips, and other attachments shall be removed and defects repaired, except where the tack welds occur within the weld area and these tack welds do not exceed the size of the completed weld. Cracked tack welds shall be removed. Areas to be repaired shall be ground to clean metal and then repaired by building up with weld metal. The repaired areas shall be ground smooth to form a plane surface with the base metal.

F. DEFECTS AND REPAIRS:

Welds with cracks, slag inclusions, porosity, undercutting, incomplete penetration, or which are otherwise deficient in quality or made contrary to any provisions of these specifications shall be removed by chipping or grinding throughout their depth to clean base metal. Calking or peening of welds to correct defects shall not be done. Welds found deficient in dimension but not in quality shall be enlarged by additional welding after thoroughly cleaning the surface of previously deposited metal and the adjoining plate. Weld deposits, slag, weld spatter, and projections into the interior of the pipe shall be removed by grinding.

3.03 MARKING, SHIPPING, AND STORAGE

All pipe, fittings, and fabrications shall be properly marked with type, gage, and heat number. All fabricated piping shall have openings plugged and flanges secured for storage and/or transport after fabrication. All fabricated piping shall be piece-marked with identifying numbers or codes which correspond to the Contractor's layout and installation drawings. The marks will be located on the spools at opposite ends and 180 degrees apart. Pipe spools shall be loaded and blocked and lagged as necessary to ensure protection from damage during shipping. Stainless steel pipe and fittings shall be stored per manufacturer's recommendation. Dents, gouges, and scratches in stainless steel pipe and fittings are not acceptable and are reason for rejecting pipe and fittings.

3.04 FABRICATION/INSTALLATION REQUIREMENTS

The piping supplier during manufacturing, fabricating and handling stages, and the Contractor during handling and installation stages, shall use extreme care to avoid the contact of any

15067-7 ferrous materials with the stainless steel piping. All saws, drills, files, wire brushes, etc. shall be used for stainless steel piping only. Pipe storage and fabrication racks shall be nonferrous or stainless steel or rubber-lined. Nylon slings or straps shall be used for handling stainless steel piping. Contact with ferrous items may cause rusting of iron particles embedded in the piping walls. After installation, the Contractor shall wash and rinse all foreign matter from the piping surface. All welded joints shall be treated with a pickling solution, brushed with stainless steel wire brushes and rinsed clean. If rusting of embedded iron occurs, the Contractor shall pickle the affected surface with Oakite Deoxidizer SS, or equal, scrub with stainless steel brushes, and rinse clean.

2.03 CONSTRUCTION

Air release valves shall be float operated, compound lever type, except air release valves less than 1-inch may be simple lever type.

Air and vacuum valves shall be designed to protect the float from direct contact of the rushing air and water to prevent the float from closing prematurely in the valve. The seat shall be fastened into the valve cover, and shall be easily removed if necessary. The float shall be center or peripheral guided for positive shutoff into the seat.

Combination air valves, unless otherwise specified, shall be single-body construction in sizes 1- through 6-inch and dual-body construction in sizes 8-inch and larger. Single-body construction shall be designed to provide all functions within one housing. The body inlet shall be baffled to protect the float and the large and small orifices shall be designed so that during large orifice closure, the small air release orifice will open to allow small amounts of air to escape. Dual- body construction shall combine one air and vacuum valve and one air release valve with interconnecting piping and gate valve.

Air valves for vertical turbine pumps (sizes 3-inch and less) shall be designed and constructed as specified for air and vacuum valves except the discharge orifice shall be fitted with a throttling device to regulate and restrict air venting and establish a pressure loading on the rising column of water on pump start. Unless otherwise specified, air valves, 4-inch and larger, shall be dual body combination air valves except the inlet shall be fitted with a surge check to prevent water column entering the valve on pump start.

Valves shall be suitable for pressures up to 150 psi.
