Hanson <br />The Little Canada water tower is a 1.5 million gallon hydropillar -style tank that was built <br />in 1977. It was repainted in 1989 and those coatings have held up until now. Twenty - <br />five years is a very long time for coatings to hold up so the City was very fortunate that it <br />worked out as well as it did. But the time has come to refurbish the tower to ensure that <br />it remains in good condition. <br />The tower has been inspected numerous times over the past 15 years and the most recent <br />inspection included the following work that needs to be completed on the tower. <br />- Blast and re -paint the interior wet surface of the tank <br />Spot repair and paint areas as needed of the dry interior surface of the tank <br />- Pressure wash and overcoat the entire exterior of the tank, including spot repairs <br />as necessary <br />Blast and re -paint the pit piping <br />- Various miscellaneous repairs to meet OSHA and AWWA standards <br />The fact that the exterior surface only needs an overcoat is very good news. This means <br />the tower does not have to be rigged up to contain the material that would be sandblasted <br />off and that reduces the price dramatically. An overcoat should last another 15 -20 years <br />and then the exterior will require a full blast and re- paint. The current coating has faded <br />and mildew has started to form on the underside of the bowl. The plan is to use a similar <br />color as is currently on the tower and change the lettering on top a little bit so it is not just <br />block lettering. Staff is working on incorporating the new letterhead logo into the design. <br />The interior wet surface is the area inside the tank where the water is stored. It has <br />shown some signs of deterioration but has held up well. That is likely due to the good <br />1 <br />
