The Regional District of Nanaimo (RDN) is one of the fastest growing regions in British Columbia, Canada with a population of more than 131,000.  The RDN manages 7 different well fields and a total of 25 wells.  In order to manage long term production capacity, the RDN is implementing a comprehensive program to maintain well capacity through performance monitoring and preventive maintenance.   Performance factors such as pumping volume, time in operation, water levels and specific capacity are collected for each well and entered into a database.  Information in the database is used to develop graphs that depict trends in water production, pumping levels, static levels and specific capacity.  This information is then used in conjunction with other operational data to identify a number of wells each year for routine well rehabilitation.  During well rehabilitation the RDN uses the opportunity to make upgrades to each well monitoring system or infrastructure if needed.  This proactive approach minimizes the chance of an emergency shutdown during the peak summer pumping season and enables better planning for water use to the rapidly growing area.
