August 22, 2018 - Tomahawk Cleans and Lines Watermains in Alma, Quebec
Pre-Project Condition:
This project contained both 150mm (6”) and 200mm (8”) pipe on a dead end street which was experiencing water quality issues. The watermain required a water blow-off to reduce red water and maintain chlorine levels. Moderate internal pipe deposits had negative impact on water flow rates
