There are many professionals who work in the field of blocked drains. Each one has a unique set of skills that make them an important part of any team tasked with fixing or cleaning up a blockage. One such professional is the hydrologist. This person specializes in understanding how water moves through landscapes and ecosystems as well as studying changes over time due to human activity or natural events like floods or droughts. By knowing all this information about drainage systems and their surrounding areas, Hydrologists can help identify potential problems early on so they can be fixed before they become bigger issues. Another profession that often works closely with blocked drains is the civil engineer . Civil Engineers design buildings (both new ones and renovations), roads and other infrastructure projects across different parts of the world including countries where sanitation standards may not meet international norms For example , if you have an old house which leaks sewage onto your neighbour’s garden then your neighbour could call in a civil engineer to assess whether it would be possible to fix things without having to tear down either property entirely – something that might not always be practical depending on location etc.. If it turns out there isn’t much option but for demolition than another member from engineering staff like plumbers will need involved too… The point being is these guys know everything about building structures both big & small! So while at first glance some professions might seem less likely related 2 drain clearing / repair - think again!!! !
