Air Testing

Air testing is a method of testing the integrity of the pipeline and the structures that may be used in lieu of the method prescribed in paragraph A. (above). Also, the Coral Springs Improvement District may direct the use of air testing under certain circumstances.

Testing procedures shall be in accordance with the following requirements. The results of the testing will be evaluated by calculating the allowable times in accordance with charts created by the Coral Springs Improvement District.

At the start of the test, the pipelines are stabilized by pumping the lines with air to achieve a constant test pressure (for piping above the ground water table, it is necessary to achieve a constant 3.5 PSI; do not exceed 5 PSI).

Maintain the test pressure for 5 minutes and do not permit the pressure to drop more than 0.5 PSI below the test pressure.

The test period begins when the pressure is adjusted to exactly 3.5 PSI (for piping above the water table) and the pressure supply is shutoff. When the pressure bleeds to 3.0 PSI, start the test timing. Stop the time when the pressure bleeds to 2.5 PSI. Determine the time differential and compare it to the applicable charts (when calculating the allowable times).

If the bleed down time exceeds the allowable time per the chart, then the line passes. If the line reaches 2.5 PSI prior to reaching the allowable time, then it fails.

For piping that is below the water table, the above procedures are the same, except that all pressures shall be adjusted (+) 0.433 psi/ft below the water table.

Gravity Sewer Lateral Testing

Infiltration/Exfiltration Gravity Sewer Laterals

Infiltration and exfiltration testing (Two feet of Head for exfiltration; zero head for infiltration) of service connection lines shall be done in conjunction with the testing of the lateral and/or main line sewer. No additional leakage allowance will be made for service lines.

Infiltration testing of service lines will not be permitted unless a minimum 2̓ (feet) static head of ground water exists over the shallow end of the service line at cleanout.

Visual Inspection Gravity Sewer Main Lines

On completion of each block or section of gravity sewer, or such other times as the Coral Springs Improvement District may direct, the block or section of sewer is to be cleaned, tested and inspected. Each section of the sewer is to show, in examination (lamping) from either end, a full circle of light between manholes. Each manhole or other appurtenance to the system, shall be of the specified size and form, be water tight, neatly and substantially constructed, with the top set permanently to exact position and grade. All repairs shown necessary by the inspection are to be made; broken or cracked pipe replaced; all deposits removed and the sewers left true to line and grade entirely clean and ready for use.

T.V. Inspection Gravity Sewer Main Lines

After all other testing has been successfully completed, a television inspection of all lines shall be completed by Contractor. Any defective work or necessary corrections found during this inspection must be corrected by the Contractor, at his expense, before the lines can be accepted for operation and maintenance by the

Coral Springs Improvement District. All mud, sand, debris and other deposits shall be removed by approved methods prior to TV inspection.

Review and approval of the tapes must be completed by Coral Springs Improvement District Personnel.

The percent of standing water at a sag in a sewer main will determine if the pipe is acceptable or not.

Sags that make up 5% or less of the pipe area are approved.

Sags that are between 5-10% of the pipe area are at the discretion of the Coral Springs Improvement District to accept or reject.

Sags that are more than 10% of the pipe area are unacceptable and should be rejected unless justified by the Engineer of Record to the Coral Springs Improvement District. Acceptance is not final until agreed to by the Coral Springs Improvement District. A letter of credit or a performance bond will be required for sags such as this; warranty extensions without this protection are not acceptable.

Testing Backfill

Compaction and Densities Testing

Methods of control and testing of backfill construction to be employed in this work are:

Maximum density of all backfill material shall be determined by ASSHTO T- 180 (ASTM D 1557).

Laboratory and field density tests, which, in the opinion of the Coral Springs Improvement District are necessary to establish compliance with the compaction requirements of these specifications, shall be made at such depths and locations as selected by the Coral Springs Improvement District.

Trench backfill which does not comply with the specified densities, as indicated by such tests, shall be reworked and recompacted until the required compaction is secured, at no additional cost to the Coral Springs Improvement District.

The first test shall be 12” above the top of pipe or the water table, and in 6” lifts thereafter.

Backfill testing fees shall be paid by Contractor (Testing Lab shall be approved by Coral Springs Improvement District).

7.0	MINIMUM EASEMENT REQUIREMENTS

ITEM	EASEMENT REQUIREMENT	

Water Mains and Sewer Force Mains	10 foot minimum width with no less than 5 feet on each side of the main. Minimum width may be reduced if the easement is parallel to and contiguous to a public right of way. The easement must extend 10 feet beyond the terminus of the main.	

Sewer Gravity Mains <8'depth	15 foot minimum width with no less than 7.5 feet on each side of the main. Minimum width may be reduced if the easement is parallel to and contiguous to a public right of way. The easement must extend 10 feet beyond the terminus of the main.	
Sanitary Gravity
Mains >8' depth	20 foot minimum width with no less than 10 feet on each side of the main.
Minimum width may be reduced if the easement is parallel to and contiguous to a public right-of-way. The easement must extend 10 feet beyond the terminus of the mains.	

Water Main and Sewer Gravity Main In Same Easement	30 foot minimum width based on 7.5 feet for the water main, 12.5 feet for the
sewer gravity main and 10.0 feet separation between the two mains. Minimum width may be reduced if the easement is parallel to and contiguous to a public right of way. The easement must extend the greater of 12.5 feet beyond the terminus of the sewer gravity main or 7.5 feet beyond the terminus of the water main.	

Fire Hydrant	7.5 feet on each side of the hydrant. Easement may be combined with
minimum water main easement.	
Backflow Preventer, Large User Meter	10 foot minimum on each side of meter vault or backflow preventer. Easement may be combined with minimum water main easement.	

Lift Stations, Pump Stations	30 feet by 30 feet. Under some circumstances Coral Springs Improvement District may approve a smaller easement but it is unusual for the easement to be less than 25 feet by 25 feet.	

All Others	
Check with Coral Springs Improvement District.	

Easement descriptions are to be written clearly on 8 ½“ x 11” paper with a point of beginning and a point of termination. A sketch drawn to scale and on 8 ½“ x 11” paper shall accompany the description. The sketch is to reflect the description and shall carry additional information to facilitate construction of the worded description. Street corners are to be shown and the description/sketch should relate the property being described to the streets. The scale shall be such to enable the direction of lines to be clearly observed. Where warranted, the sketch is to be on more than one sheet with the proper match lines shown for each sheet. Coral Springs Improvement District reserves the right to approve the description and sketch.

Easement descriptions and sketch must meet minimum technical standards and be signed/sealed by a Florida registered land surveyor.
