Found the article I was referring to about how the penalties were insignificant and not a strong enough incentive for them to do anything about it. Extract from the article :

"The Observer revealed in 2013 that the most persistent and frequent polluters of England’s rivers and beaches were the nation’s 10 biggest water companies. They committed more than 1,000 incidents between 2005-13 but were fined a total of only £3.5m, a sum described as “pitiful” by a senior MP at the time."

That's a measly 3500 pounds per offence. That's way cheaper than adopting Envirosuite. Article however does indicate that steps have been taken to increase the fines but clearly making it compulsory to have real time monitoring systems is a better way to go about it in terms of protecting the environment.
