WATER RESOURCES & SUSTAINABILITY

BUSH TREATMENT FACILITY Media Refresh

One of the treatment systems the City uses for our drinking water is “packed tower aeration.” Air is pumped through the tower packed with plastic media and mixes with water as it flows through the tower This aerated water increases the pH of the drinking water, reducing the corrosion potential in the water system and for customer piping inside their businesses or residences Both the Bush and Palermo Wellfields use this treatment process which requires routine maintenance to ensure effective treatment of the drinking water. The plastic media is effective for approximately 10 years, and was recently replaced at the Bush Wellfield by the Water Quality crew, led by Curt Shields Rocky Smith, Dennis Ashe, and Cody Scharber, with assistance from the Sewer Collections and Stormwater maintenance crews, removed the old media and hand packed 117,000 individual pieces of new media in the tower. Through their ingenuity and teamwork, staff developed an efficient means to remove and repack the tower, as seen below. The project was a success, completing all annual maintenance needs for the facility and returning it to production providing clean and reliable drinking for all our customers.
