We were called initially to clear a storm system which was reported to be blocked.
Upon inspection we found a chamber full up to the top with fat/grease caused by restaurants putting oil down the drains.
Once we emptied we found the chamber to be a foul chamber which was blocked, and we traced two further chambers which were also blocked.
We had to use high pressure jetting equipment and a waste water tanker to remove the contents and carry out a full line clean out to the main sewer. Once completed we left site in a good flowing order.
