You need to know what happens if a drinking water supplier does not do their job. The chief executive checks if the supplier has not followed the rules or if there is a risk to public health, as stated in section 84. They can then choose to appoint someone else to do the supplier's job or make the supplier appoint someone. You should understand that the chief executive has the power to make these decisions. They can appoint one or more operators to take over the supplier's functions. This means the new operators will do the jobs that the supplier was supposed to do under the Water Services Act 2021. The chief executive can also require the drinking water supplier to appoint new operators. This is another way to make sure the supplier's jobs get done. The new operators will perform the supplier's functions or duties as stated in the Act.
