Reducing the operating costs of water infrastructure projects demands improved efficiencies in operating treatment plants (water and wastewater). To eliminate or reduce contaminants in raw water in order to render it safe for drinking, or to reduce pollutants in wastewater to render it acceptable for disposal into our environment, costs money. These operating costs include the following:

  1. Wastewater discharge fee/Water resource fee
  2. Electricity cost
  3. Chemical cost
  4. Staff cost
  5. Maintenance and replacement cost
  6. Administration cost
  7. Sludge disposal cost
Operating costs need to be recorded and analysed in the course of operating and maintaining the plant, thereby allowing Management to identify areas for conservation and to determine where costs are being expended inefficiently so that appropriate measures can be taken to reduce costs.
