Small to medium sized wastewater treatment plant operators are characterised as operators who prefer an install and forget system, because while operating a WWTP may be integral to their business, it is not their primary business. Typically they rely on a failure based maintenance culture as they do not have a staff member or maintenance crew available for the upkeep of a wastewater treatment plant, nor do they have large budgets available for the implementation of in-house preventative maintenance.
