Criteria for closing a wading pool - This document was given to CELOS in 2011 by the assistant to Councillor Bailao. The assistant has not been able to find out from city staff if these criteria were generated by the Ministry of Health Long Term Care, or the City.
When provincial Health Ministry staff wrote new rules for wading pools, they unwittingly overrode a deliberate decision by our elected Cabinet Ministers - that wading pools are not to be regulated like public swimming pools.
Devising unauthorized new rules is expensive - and the costs are largely buried. What did all of the staff time to create the host of current wading pool rules cost? Are these and the accompanying enforcement and training costs recorded - as clear budget items - when we discuss wading pool costs?
CELOS' has looked in more detail at a number of these documents.
Chlorine no greater than 5mg/l and no less than 3 mg/l
Life Saving Society
Because wading pools have a small water volume and are used by very young children, the Lifesaving Society recommends maintaining higher levels of chlorine disinfectant than the minimums used for swimming pools. The Society recommends maintaining a minimum Free Available Chlorine (FAC) of 3.0 – 5.0 ppm at all times. Frequent testing is required to verify that the required FAC and pH levels are maintained - every 4 hours or more frequently depending on bather load.
