ABSTRACT
Monitoring equipment can be very important to the successful operation of groundwater control systems. Every groundwater control system includes pumping equipment of some sort, and it is essential that mechanical and electrical plant in the system is appropriately maintained as a preventative measure to reduce the risk of sudden failure of pumps. Groundwater lowering systems, on the hand, may sometimes pump water that is significantly brackish or saline – this is likely in coastal areas or aquifers where saline intrusion has occurred, or in very arid climates where groundwater can be highly mineralized with a very high salinity. Systems pumping brackish or saline groundwater may be subject to very severe corrosion during even a few months of pumping. Diesel-powered pumps or generators will require regular fuelling and checking and replenishment of lubricant and coolant levels. Electrically powered equipment typically requires less maintenance but should be tested regularly.
