InDepth Water Management were requested to carry out a hydrostatic pressure test on a 200mm water main to allow final connection to the Irish Water network in Cavan.
At InDepth, we conduct all hydrostatic pipeline pressure testing in accordance with IGN 4-01-03 2015 standards.
Below are 10 key steps for such works to be carried out:
- Prior to any testing, operative confirms the type of line to be tested (HDPE/MDPE/DI)
- Identifies all air valves, sluice valves and hydrants along the line
- Operative confirms the correct installation of the test end plate and blank end plate
- Pipeline filled from the lowest available point with water
- Air is removed by use of air vents/hydrants at the highest point
- A period of time is allowed to ensure the water level is stable / Allow the water to stand for stabilisation
- Operative raises the pressure in a controlled manner
- Pressure to be monitored from the lowest level
- If the result of the pressure test is successful only then can chlorination commence
- Once works have been completed an independent sample is to be taken and a report issued to the client within 7 working days
