The water pipeline has been in use for more than forty years and transports water from Andijk to Heemskerk. It is also used to supply production water to TATA Steel. The landowner sounded the alarm and reported to PWN that water was coming out of the ground!
What repair options are there in the event of a water leak?
The easiest option to choose when repairing a leak is to interrupt the water supply. That then makes the task of replacing a broken pipe relatively easy. The major drawback is that consumers will then be without water for a period of time.
PWN chose not to leave its customers without water. The technical solution which Imbema advised PWN to use was the DuoFit coupling, a unique coupling which ensured that PWN could continue to supply water. In this case, 4200 cubic metres of water could still be supplied as normal!
