PURPOSE

Pender County seeks proposals from qualified firms and individuals to install pressure filters at five (5) well locations for the purpose of providing treatment for iron removal. Pender County

Utilities has constructed five (5) groundwater wellhouses along the US-17 corridor in Scotts Hill and Hampstead that provide potable water to residents and businesses in the area. Iron and hydrogen sulfide in the groundwater has resulted in customer complaints. Pender County

Utilities intends to install a pressure filter system at each wellhouse with associated piping, valves, controls, and media. Pender County is seeking a qualified contractor for a turnkey installation that includes disinfection, testing, and startup of each system. The work will be completed sequentially so that construction is only occurring at one wellhouse at a time.

FINAL DESIGN - NOT FOR CONSTRUCTION

1. Inspect for piping defects that may be detrimental as determined by the Engineer.

2. Repair damaged piping, or provide new, undamaged pipe.

3. After installation, inspect for proper supports and interferences.

B. Pressure Testing:

1. Test Pressure: Not less than 150 psig or 1.5 times the system’s working pressure, whichever is greater.

2. Conduct hydrostatic test for minimum two hours.

a. Fill section to be tested with water slowly and expel air from piping at high points.

b. Install corporation cocks at high points.

c. Close air vents and corporation cocks after air is expelled.

d. Raise pressure to specified test pressure.

4. Observe joints, fittings, and valves under test.

5. Remove and renew cracked pipe, joints, fittings, and valves showing visible leakage and retest.

6. Leakage:

a. Correct visible deficiencies and continue testing at same test pressure for additional two hours to determine leakage rate.

b. Maintain pressure within plus or minus 5 psi of test pressure.

c. Leakage is defined as quantity of water supplied to piping necessary to maintain test pressure during period of test.

NOTE: Flexible connectors must be installed between hard piping and tank openings. These pressure vessels are treated for an internal negative pressure of 5y HG (17 Pa) vacuum below atmospheric. If negative pressure could ever exceed 5y Hg (17 Pa), an adequate vacuum breaker must also be properly installed. Failure to install flex connection properly, or improper installation of a vacuum breaker when required, may void the warranty.
