Why should oils and fats are not be poured into drains?

It is illegal to dispose of oils and fats into the public drainage system, once a liquified oil is poured down a drain it will start to solidify, when done regularly this will start to build up and create blockages within the drainage systems. These blockages will contribute to over 200,000 blockages of drainage systems in the UK every year.
