In order to account for the effect of water quality, surface water and groundwater were modelled based on parameters and assumptions derived from literature. E. coli was selected as the indicator microbe to evaluate the level of contamination in the study. The algorithms for the operation and maintenance requirements for each technology were designed to achieve a consistent log reduction and disinfection efficacy of 3 logs (at a minimum) for all systems evaluated. To achieve the set level of efficacy for each system, a comprehensive assessment was conducted to determine the necessary capital materials and consumables based on raw water quality. This assessment had implications for both cost and environmental considerations. Therefore, the different water quality parameters for groundwater and surface water sources serve as the contextual parameters modelled into the systems. For instance, groundwater source will most likely have higher hardness due to water dissolves minerals as it moves through rocks. Both waters have 1,500 -2,500 CFU⋅100 mL -1 of E. coli. A characteristic groundwater had a turbidity of 1 -10 NTU and hardness of 60 -120 mg⋅L -1 as CaCO3, and characteristic surface water had a turbidity of 10 -30 NTU and hardness of 0 -60 mg⋅L -1 as CaCO3.
