The objective of water treatment is to provide a safe and aesthetically pleasing water for domestic, commercial and industrial uses. ABL engineers have developed process equipment for domestic water supplies and municipal systems for sale by Rawdon Technologies Limited. These systems use dissolved air flotation (DAF) to separate floc faster and more positively than by gravity settling. DAF can achieve effluent turbidities less than 0.5 NTU resulting in longer filter runs and longer filter life. The entire system is constructed in modular units, usually of stainless steel. ABL has designed water treatment systems for the Town of Stewiacke and the Village of Sherbrooke and Orangedale. ABL has been process designer on a design build team for the City of Dartmouth Water Treatment Plant.
 
Water treatment plant audits have been completed for communities including Mahone Bay. A water treatment plant audit was done for the City of Bathurst and resulted in a new operations manual and training of operators. Treatability studies have been conducted for Coxheath, Chapel Island, Orangedale, and Sherbrooke. Predesign studies have been completed for Coxheath in Cape Breton Regional Municipality including pilot plant operation using Rawdon's automated pilot trailer with full data acquisition capabilities.
 
Water distribution studies, modelling and designs have been conducted for the Town of Liverpool resulting in the design of a pressure booster station and pressure zone separation in the Town. Watermain replacement has been completed in the Town of Stewiacke to alleviate watermain breakage and losses. Upgrades have been done to water distribution in the Town of Lunenburg.
