The Village of Lumby operates the water treatment and distribution system. The water source system consists of three deep wells. In 2010, when the third well was completed, the source and treatment capabilities rose to 5,080,320 litres per day. More importantly the well delivery system offers a surety of supply.
The water is pumped to the filtration plant, where a filtration process takes place to remove iron and manganese (aesthetic purposes only) through a sand filter system. Sodium hypochlorite is introduced to disinfect the water as required by the Interior Health. The once filtered and chlorinated water is pumped to a lower reservoir with a holding capacity of 2,649,788 litres. The water from the lower reservoir is fed into the distribution system by gravity for the lower portion of the Village and is also pumped to the high Reservoir located above Miller Street for distribution to the community, also by gravity. The high reservoir is capable of storing 1,620,156 litres of water.
The regulations require that the water system have the capacity storage for a two day supply of domestic use and a fire fighting supply to meet the Underwriters requirements.
Daily inspections of the water filtration plant and pumping stations is required. During the course of the year as part of the normal operations of the utility, the Public Works Department inspect the fire hydrants, exercise all the water valves and flush the water mains on an annual basis to assist in cleaning the water mains. The department also repairs individual service valves to the property and repairs to the water distribution mains.
Monitoring of the available chlorine in the distribution water mains are collected within several sites throughout Lumby and inputted into a state of the art SCADA system. Within this powerful program, the deep aquifer Lumby utilizes for potable water is also monitored 24 hours a day, showing the reaction of the aquifer during heavy and light use.
The Village has completed a universal water metering program in 2009 and during the course of 2010, water meter usage readings were now captured on a monthly basis. During the course of 2010, a rate structure was developed that ensures long term maintenance of the water system and future capital expenditures or replacement are covered. In 2011, the consumers were invoiced on a user pay basis. With the installation of water meters, a modest decrease of water consumption was targeted to be around 20% in annual consumption, but as of year-end of 2012, the Village of Lumby has seen a reduction of 32.6% in its annual water consumption.
The Village of Lumby Water Distribution System must adhere to conditions set out by the Interior Health Drinking Water Permit to operate their water system. One of the conditions stipulated by Interior health is to institute a Cross Connection Control Program. In 2010, the Village of Lumby adopted a Cross Connection Control Program and accompanying Bylaw that mandates all industrial and commercial property owners install a back flow prevention device at their building or property which protects from any back flow conditions. This program is administered and managed by the Village of Lumby.
