Normal excavation will be considered from the outside pipe dimension plus 18 inches each side, unless otherwise designated on the plans.

Unsuitable foundation material shall be removed below the normal designed elevation as directed by the Town of Middletown.

When a pipe is to be placed either partially or completely in a fill, the embankment shall be compacted to an elevation of one foot above the top of the proposed pipe installation for a minimum of 36 inches on each side of the pipe.

Trench or ditch bottoms containing bedrock, soft areas such as muck or refuse, or other material unable to provide long-term support to the pipe are unacceptable. Remove rock and other unyielding material one foot below the pipe bottom and six inches on either side of the pipe unless otherwise directed by the Town of Middletown. Excavate soft areas to a depth of two feet below the pipe bottom and three times the width of the pipe unless otherwise directed by the Town of Middletown to excavate deeper or wider. If a firm foundation is exposed, replace the excavated material with acceptable backfill material and compact to 95% Modified Proctor density.

If the soft area remains after excavation, and if approved by the Town of Middletown, synthetic fabric (geotextile) shall be used to separate the native soil from the backfill. After the fabric has been laid on the native soil, replace the excavated material with acceptable backfill material and compact to 95% Modified Proctor density.

When rock, hardpan or other unyielding material is encountered, the trench shall be excavated as shown on the plans for bedding in rock, or as directed by the Town of Middletown in the absence of a detail, and shall be backfilled with materials meeting the requirements of this section.

Backfill and compaction.

All trench backfill shall be compacted. Backfill of pipe shall be compacted with equipment in a manner which is capable of producing the required results. Backfill material shall be placed and graded in uniform horizontal lifts, which may not exceed eight inches. Compaction will not be performed by jetting or water settling. If during the compaction of the trench, any soft, yielding, or spongy areas are observed, backfilling operations will cease until stability of these areas is achieved. The Town of Middletown has the authority to request field moisture/density control tests to document compliance of work as per DelDOT's specifications. Failed areas shall be compacted again and retested. A geotechnical consultant approved by the Town of Middletown shall perform moisture/density tests at the expense of the owner/developer.

Water main pipe bedding shall be per standard detail W-3.

Where the pipes are under the roadway pavement or shoulders, the backfill material shall be compacted in a maximum of eight-inch lifts to 95% of the Modified Proctor density.

Where pipes are not under the roadway pavement or shoulders, compaction shall be in a maximum of eight-inch lifts to 92% Modified Proctor density.

Cleaning. Pipe and fittings shall be thoroughly cleaned before they are laid and shall be kept clean until the acceptance of the completed work.

Cutting. Whenever a pipe or fitting requires cutting, to fit into the line or to bring it to the required location, the work shall be done in a satisfactory manner to leave a smooth beveled end, and without extra compensation.

Joining pipe and fittings. In joining pipe and fittings, the contractor shall exercise particular care to insure that the outside of the spigot and inside of the bell is entirely free of oil, tar and greasy substances to insure a tight fit. All concrete required to construct buttresses behind plugs, tees, hydrants, bends and other fittings and anchorages beneath vertical bends shall be placed in accordance with the standard details or as shown on the plans.

Installation of valves and fittings.

Install fittings and valves where indicated on the plans, or as directed by the Town of Middletown. Where valves occur on the end of the pipeline, place a cast-iron plug and secure in the exposed bell before backfilling the trench. Buttress the valve.

A valve box shall be carefully placed over the bonnet of each gate valve with the top at the finished surface of the street sidewalk or at such other elevation, as the Town of Middletown shall direct. It shall be set plumb. In tamping the backfill around the box, special care shall be taken to keep the box plump and to have it firmly supported to avoid settlement. Any box which is found out of plumb, or which is not firmly supported, shall be excavated and reset in a satisfactory manner.

There shall be as many valves installed as there are pipes entering and leaving any pipe intersection, typically three valves at each tee, and four valves at each cross.

Valve boxes shall be set in such a manner that the operating nut of the installed valve is set center in the valve box.

This section shall consist of disinfecting all newly laid water mains, including valves, fittings, fire hydrants, and all other miscellaneous accessories which carry potable water for use for domestic consumption or fire suppression in accordance with these specifications. The procedure to be used for disinfecting shall be in accordance with the latest edition of AWWA C601.

Flushing and disinfection.

All new sections of water main must be thoroughly flushed, disinfected and tested for bacteriological quality before the water main can be put in service.

Flushing of the main shall be performed to remove any mud and debris left in the pipe from the installation. All flushing activity must be coordinated with the Town of Middletown.

The contractor shall disinfect the new water system by placing in each length of pipe, hydrant, hydrant branches and other appurtenances, a sufficient amount of calcium hypochlorite tablets to insure adequate disinfection. Tablets shall be fastened to the inside top of every length of pipe, hydrant and appurtenance, using a food-grade adhesive or glue that is nonharmful to human consumption. All adhesives or glues used to secure tablets must be approved by the Town of Middletown prior to use.

The contractor shall be entirely responsible for achieving minimum residual chlorine content of five ppm at the extremities of the water mains after 24 hours or more contact with the full water pressure on the main.

Water for filling the mains shall be introduced at a velocity of less than one foot per second in order to permit the tablets to completely dissolve and have a reasonably uniform distribution throughout the mains. Introducing water to the main at this velocity will help keep the tablets from becoming dislodged and washed to the end of the system.

Water for disinfection shall be furnished by the contractor from a source approved by the Town of Middletown.

The contractor shall furnish and install all material, labor and equipment required to sterilize the pipe section.

The chlorine solution should be maintained in the pipe a minimum of 24 hours before a bacteriologic sample is taken.

Chlorine residual.

After the chlorine has been in contact with the mains for 24 hours or longer, samples collected from the extremities of the mains shall indicate residual chlorine content of five ppm or more.

The contractor will be held entirely responsible for securing a minimum residual chlorine content of five ppm at the extremities of the mains after 24 hours or more contact with the full water pressure on the main.

If less than five ppm residual chlorine is indicated, the system shall be drained, dechlorinated, and the disinfection treatment repeated.

If samples collected at the extremities indicate a residual chlorine of five ppm or more, the system shall be flushed until there is only a normal chlorine residual (1.0 ppm or less) present, as determined by the DPD Method Test.

Bacteriological testing.

After a new pipe has been disinfected and flushed, it shall be refilled with water from the distribution system and tested for bacteriological quality.

No pipe or pipe section shall be placed into service until after it has been tested.

No samples shall be taken until after the pipe has been filled for 24 hours with system water.

The contractor is responsible for furnishing all labor, equipment, and material necessary to take the required samples.

Samples of water shall be collected from various points along the lines. The contractor is responsible for having the samples tested by either the State Health Department or a laboratory approved by the Town of Middletown.

No sample or other testing will be done without a Town of Middletown inspector present on site to witness the sampling.

If satisfactory bacteriological results are obtained, the lines may then be allowed to be placed in service. A copy of all test results shall be submitted to the Town of Middletown.

If the test results are not satisfactory, the system shall be sampled again. If the results from the second sample are still positive for the presence of bacteria, the contractor will be required to repeat the disinfection and bacteriological testing of the pipeline until the bacteriological testing is satisfactory.

§ 46-18 Pressure and leakage testing of water mains.

Description. This item shall consist of simultaneous pressure and leakage testing all newly installed water mains, including valves, fittings, fire hydrants and all other miscellaneous accessories which carry potable water for use for domestic consumption or fire suppression in accordance with these specifications.

Simultaneous pressure and leakage testing.

Prior to acceptance, all new pipes and appurtenances shall be tested as specified herein. The contractor shall be responsible for furnishing all labor, tools, equipment, materials, including water, pumps, compressors, pressure gauges, meters, and stopwatch subject to the approval of the Town of Middletown.

Any defective work, which shows up while conducting tests or before acceptance, shall be replaced or repaired by the contractor at his own cost and expense. Any leaks due to either blown joints or cracked pipe or fittings, shall be repaired by the contractor at his own expense.

All new water mains and appurtenances shall undergo a simultaneous hydrostatic pressure and leakage test prior to acceptance by the Town of Middletown.

Test restrictions:

All tests shall be conducted in the presence of a Town of Middletown inspector.

Testing of all pressure pipes shall be conducted in accordance with AWWA C600 testing requirements.

Test pressure shall be 150 psi.

(d)

The test duration shall be two hours.

(e)

Valves shall not be operated in either direction at a differential pressure exceeding the rated valve working pressure. The test pressure shall not exceed the rated pressure of the valves when the pressure boundary of the test section includes closed, resilient-seated gate valves or butterfly valves.

Pressurization.

After the pipe has been laid, all newly laid pipe or any valved section thereof, including hydrants, shall be subjected to a hydrostatic pressure of 150 psi. Each valved section of pipe shall be slowly filled with water, and the specified test pressure (based on the elevation of the highest point of the line or section under test and corrected to the elevation of the test gauge) shall be applied by means of a pump connected to the pipe. Valves shall not be operated in either the opening or closing direction at differential pressures above the rated pressure. It is good practice to allow the system to stabilize at the test pressure before conducting the test.

Before applying the specified test pressure, air shall be expelled completely from the section of piping under test. If permanent air vents are not located at all high points, corporation cocks shall be installed at such points so that the air can be expelled as the line is filled with water. After all the air has been expelled, the corporation cocks shall be closed and the test pressure applied. At the conclusion of the pressure test, the corporation cocks shall be removed and plugged or left in place as directed by the Town of Middletown.

All exposed pipe, fittings, valves, hydrants, and joints shall be examined carefully during the test. Any damage or defective pipe, fittings, valves, hydrants, or joints that are discovered following the pressure test shall be repaired or replaced by the contractor with sound material, and the test shall be repeated until satisfactory results are obtained.

The allowable leakage will be defined as the maximum quantity of water required to be supplied into the water main upon completion of the two-hour test to maintain the water pressure within five psi of the specified test pressure after the pipe has been filled with water and air expelled. No pipe installation will be acceptable if the leakage is greater than the maximum allowable leakage as calculated by the Town of Middletown. The contractor shall be responsible to repair all defects in the event the pipe is unable to maintain pressure.
