Force main pressure testing

SELECTED LINKS TO SECTIONS WITHIN THIS SPECIFICATION. This section covers the installation of wastewater force mains , including pipe,. Piping for wastewater force mains : 2-inch force mains shall be SDRCasketed.

Pressure Test : Pressure test in strict conformance with AWWA C60 Section 4. Temporary plug and anchorage system for hydrostatic pressure test.

The contractor shall not open more trench than the available pumping facilities are able to dewater to the satisfaction of .

For pressure sewers, the normal tests during the sewer laying may include, where require the low pressure air or water exfiltration tests on short individual sections.

These low pressure air or water exfiltration test are conducte when require to ensure that the joints are watertight. As in gravity sewers, the force mains . Exfiltration (Air Test ) Procedures. Pipe Alignment (Lamp Test ) Procedures. Television Inspection Procedures.

Pressure testing of water mains and sewage force mains to detect leakage prior to final payment, is common construction practice. The EJP Service Department does pressure tests with either air or water, as required. Forcemain Testing Requirements.

We are often asked why air testing must be done at lower pressures than with water. Valves and boxes with lengths to suit for sewage force main and shall be. Hydrostatic pressure testing for HDPE pipe shall be completed in two . All sanitary sewer force mains shall be constructed of either PVC or ductile. The minimum pressure class of all buried sewer force main pipe shall be as. HP Diaphragm pump styles with volume 9. For other test equipment click here.

PVC pipe is not permitted for the installation of sewer force mains. All force mains shall be ductile iron only. CAST AND DUCTILE IRON FITTINGS. Body and cover shall be of cast iron . All such pipe to be tested shall be required to sustain 5. Clean, inspect, and test sanitary sewer gravity mains, sanitary sewer force mains , and sanitary sewer service stubs.

Clean all sanitary sewers, storm sewers, and pipe culverts prior to testing by flushing with high pressure water and removing debris by vacuum extraction, and by removing sheeting, bracing, shoring, . The wastewater will be discharged. Burst Pressure Short Term (Min.) 6psi. Acceptance: The sewer will not be accepted until the leakage or infiltration rate , as determined by test , is less than the maximum allowable. House Laterals: House laterals are not to be connected until after the sewer main has been successfully tested.
