Facility Forum - Fall 2016 - 25

in the spring or fall, the water can be considered to be in a state of equilibrium and does not require any chemical treatment once balanced with buffers. It is only air laden with bacteria, spores, leaves, grass, dust or vandals tossing in debris that can require adjustment of the "water chemistry." Winterizing Above Deck Level Remove and store inside a change room all ladders, guard chairs, ring buoys, reach poles, float lines, flume ride entry and exit sections, station posts, drinking fountains, and loose play equipment. Diving boards should always be stored on their edge, never flat or used as a shelf to store other equipment. Metal or wooden boards and diving platforms can warp if not placed on their edge for the winter. Sink "U" traps should be removed and toilets and urinals fully drained, and cleaned, then removed and turned upside down or on their sides. Alternatively, ethylene glycol can be poured into all sinks, toilets and shower or deck drains to fill the traps after all water has been removed from them. The owner will need to decide whether the cost of labour to carry out the removal process or the cost of the glycol required to protect the plumbing is more financially viable. Hose bibs should be fully opened or removed as should all shower and tap fixtures after draining and isolating all water lines in unheated buildings. Water meters, vacuum and pressure gauges, thermometers, flow meters, drain plugs; should all be removed, thoroughly dewatered and the threads greased or coated with two laps of Teflon tape in late fall. Wedge anchors, deck anchors, cup anchors and starting platform sleeves; should be packed with expanded polystyrene or newsprint packing wads. Metering pumps, chemical controllers, test kits, first aid kits, SCBA, ventilators and any other obviously temperature sensitive equipment should be taken off site and kept in heated and secure storage. An ideal situation occurs when such equipment can be stored in an area where servicing in preparation for next year's season can be carried out. THE MOST CRITICAL AND EXPENSIVE PROBLEMATIC DEVICES IN OUTDOOR POOL WINTERIZING ARE THE DEEP END DRAINS. Chemical control electrodes must remain moist at all times. pH and O.R.P. probes should be taken in sealed transparent vials with KCI or balanced water in them to a warm storage area for the winter months. Should the membrane or wick area be allowed to dry, the electrode gel might seep out or expand and rupture the bulb end. At several hundred dollars each, these probes should be taken care of properly. Even finger greases or oils can permanently damage their sensitivity thus the "O" ring sealed storage bottles must be used over the winter. P.A. systems, phones, vending machines, computers and any other equipment that would attract vandalism or theft should also be taken to central stores during the off season; as well as surplus chemicals and paints. Deck Level Winterizing Skimmers require particular care. Leaf baskets should be removed and stored indoors. Weirs can be removed and stored as well. Fall is an excellent time to order replacement weirs and hinges as well as new lids and baskets. In fact, all pool equipment parts that show evidence of wear in the fall should be re-stocked prior to the New Year as pool supply houses are very busy in the spring. The trim valves and float valves that are a part of the skimmer should be removed and stored as well. Ice provides a natural pool cover after all debris has been removed from the pool through diligent cleaning and one last vacuuming of the sides and bottom. The result of thorough cleaning and preparation in the fall will result in cost savings in the spring when it may not even be necessary to drain the pool for scrubbing or painting. The use of airbags, water bubblers, logs, styrofoam panels, old tires, used telephone or hydro poles, empty oil drums and other junk to prevent outward ice pressure against pool walls is a concept without merit unless the pool walls slope inward. In this instance, the ice could jam upward with such force that an explosion-like noise as the ice or pool walls fracture might disturb the neighbours. Upward ice movement will also knock off steps, break ladders and lift coping stone slabs. Underwater lights and speakers will also be damaged by ice movement. But the ice pressure is needed to counteract the inward pressures of frozen backfill and soil around the pool walls. Most outdoor pools avoid this damage by virtue of proper design in the first instance. While there is a snow to water ratio of 7:1 (7 inches [18 cm] of snow is approximately equal to 1 inch [3 cm] of rain), drifting snow and sleet, winter rainfall and hail can contribute to fill up the pool over five to seven months. Most outdoor pool operators tend to lower the water by .5 metres or more after blowing and sealing the lines and fittings. But remember when dumping the water from a public pool in some areas of Ontario, there may be local bylaws that require the water to be released to storm sewer systems rather than the sanitary systems. At any rate, it can be considered common courtesy to contact the operators of the municipal waste water treatment systems and advise them of the volume of water you intend to dump, and what concentrations of chemicals it contains. This might also be a consideration when you plan on re-filling in the spring; contact the water treatment plant to let them know you're going to be using a considerable volume of water in the next day or so. Below Deck Winterizing Outdoor pools with liners should remain filled during winter months. An empty liner pool can actually blow away by virtue of the venturi effect of strong cross winds. Your nice community pool could thus really become a total community pool as it travels about the neighbourhood courtesy of the winter storms and winds if it is fully drained at the end of the season.
