Aldermen are set to start the debate on Calgary's fluoridated drinking water and some say the practice is costing Calgarians too much money.

Estimates to replace the aging equipment that adds the fluoride to the water is the primary concern when it comes to cost.

Calgary started adding fluoride to the water supply in 1989 after 53% of Calgarians voted in favour of the practice.

Since then, there have been 6 plebiscites on the issue and over that time more study has come to light about the health and dental benefits of adding fluoride to drinking water.

On April 6th, five aldermen entered a motion asking that fluoride be removed from Calgary's drinking water in an attempt to save money.

The motion also asked for $750,000 to help low income Calgarians who can't afford regular fluoride treatments at the dentist.

The decades old debate hits the city council table Monday.
