I do not think water meters should be compulsory, nor do I agree with meters being fitted when people move house. It is the incoming owner who should decide whether a water meter should be fitted.
The percentage of water leaks fixed is far too low. It should be at least between 50 to 75 percent. What is the point of providing more water resources only to have it leak away. Water leaks must be the main source of annoyance to customers. It certainly annoys me.
