Benefits Of High Quality Drinking Water - 1431 Words

Alum doses have steadily increased and occasionally very high doses are required during winter conditions. These high doses consume alkalinity and lower the treated water pH. This lower pH is more aggressive in terms of its potential corrosion of metal pipes. This lower pH is more aggressive in terms of its potential corrosion of metal pipes. Alternate coagulant chemicals have been evaluated to ensure the provision of high quality drinking water. The cities of Regina and Moose Jaw forecasted water sales of 29,500 ML and 6,200 ML respectively. Total actual water sales to the cities in 2014 were 28,374 ML to Regina and 5,362 ML to Moose Jaw. Sales to Regina decreased 3.6% from 2013, and sales to Moose Jaw decreased 6.0%.

Improving the handling of treatment plant residuals and increasing the clear well storage capacity were also identified among top problems to be addressed. Other objects covered an additional screw pump; provide corrosion control and address overall water treatment upgrades for the Plant. The scope was reviewed to determine the most urgent items required to be included which are also within the approved budget as both of these problem were not addressed to in the scope of project. An electrical master plan study was carried out and identified issues that need to be addressed as part of the Plant upgrades. The Board developed its first comprehensive Risk Review in 2014. There were thirty five risks identified which could impact the Plant’s ability to produce and transmit water to its customers. Of these risks, the probability and consequence varied. The top ten risks, which range from an overall medium to high risk rating, have been reviewed in greater detail and can be mitigated through the operating budget, capital budget or the unfunded program of work. After testing at bench-scale and short-term full plant trials, a polyaluminum chloride coagulant was chosen for long-term evaluation. This particular coagulant is not compatible with
