8.2.7  Prepare management procedures

A set of clear instructions to enable the whole water supply system to be operated as desired has to be in place. If there is an incident that disrupts the normal operation of the system – for instance, if a control measure fails – then a number of actions need to be followed. These should be documented in the management procedures so that they are easy to refer to and apply. The relevant management procedure will detail the remedial measure, what communications to undertake and the steps to follow in an investigation of the failure.

  • Do you remember the usual name for the routine instructions for operating a water treatment plant?

  • They are often referred to as standard operating procedures or SOPs.

Following through the example of chlorine stock, if the supply were to run out, the management procedure might suggest contacting nearby water utilities (using names and telephone numbers of contact persons who had previously been consulted) for a loan of an amount of chlorine. An alternative might be to contact supply companies that could rapidly acquire and supply the chemical (but this is likely to be at a high cost!). The population affected by the break in supply would have to be informed of the crisis, possibly by messages on local radio and television programmes. Lastly, an investigation needs to be undertaken as to how the crisis came about, and how it can be prevented from recurring.
