“…Although operation, maintenance, and security concerns may deter utilities from adopting booster disinfection (Walski et al, 2003;Boccelli et al, 1998), recent literature discussing its benefits (Munavalli and Kumar, 2003;Prasad et al, 2004;Tryby et al, 2002;Propato and Uber, 2004;Ostfeld et al, 2006) suggests an increase in use and comfort level among drinking water utilities. In addition, it has been shown that booster disinfection used in conjunction with a water quality sensor network can be an effective first response to a contamination event that caused disinfectant residuals to drop to unsafe levels (Parks and VanBriesen, 2009). The extent of protection afforded by booster systems varies according to the attributes of the drinking water distribution system, such as branched versus looped flow paths and the number and location of storage tanks (Propato and Uber, 2004).…”

“…The potential for a boost-response system (chlorine boosters triggered by a sensor network) to provide substantial protection and allow for uninterrupted service during an intrusion event was evaluated by Parks and VanBriesen (2009). Random contamination events were simulated in a model water distribution system with an optimized sensor network.…”

“…A second, confirmatory detection may subsequently lead to a 'do not consume' order. This combination of a boost at the first detection and a 'do not consume' order at the second detection can be an effective means of reducing the volume of consumed contaminated water (Parks and VanBriesen, 2009). Parks and VanBriesen (2009) also illustrated how the use of distribution system modeling and database management can be useful to utilities for efficient disaster response.…”

Parks and VanBriesen (2009) also illustrated how the use of distribution system modeling and database management can be useful to utilities for efficient disaster response. The study showed that if exhaustive disinfection scenarios are simulated and the results managed in a database, a utility needs to merely simulate the contamination scenario once and query the database to determine the effects of a multitude of responses, such as boost response, issuing a 'do not consume' order, or waiting for a second detection to respond.…”

“…Researchers have examined different methods for determining the optimal schedule of disinfection boosters to maintain adequate levels of residual chlorine throughout the distribution system (Boccelli et al 1998(Boccelli et al , 2003Tryby et al 1999Tryby et al , 2002Munavalli and Kumar 2003;Ozdemir and Ucaner 2003;Propato and Uber 2004;Parks and Shannon 2009;Ostfeld et al 2010). Thus, knowledge of residual chlorine concentration throughout the distribution network suggests the water utilities regarding selection of chlorine application strategy i.e.…”

Knowledge of residual chlorine concentration at various locations in drinking water distribution system is essential final check to the quality of water supplied to the consumers. This paper presents a methodology to find out the residual chlorine concentration at various locations in simple branch network by integrating the hydraulic and water quality model using first-order chlorine decay equation with booster chlorination nodes for intermittent water supply. The explicit equations are developed to compute the residual chlorine in network with a long distribution pipe line at critical nodes. These equations are applicable to Indian conditions where intermittent water supply is the most common system of water supply. It is observed that in intermittent water supply, the residual chlorine at farthest node is sensitive to water supply hours and travelling time of chlorine. Thus, the travelling time of chlorine can be considered to justify the requirement of booster chlorination for intermittent water supply.

Contamination in water distribution network (DN) can be catastrophic if free residual disinfection is not present. To ensure drinking water quality in a DN, ensuring detectable levels of free residual chlorine is a common practice in most municipalities. Higher chlorine doses can be applied in this respect, but this can produce detrimental disinfection by‐products (DBPs) such as trihalomethane and Haloacetic acids, and chlorine‐related taste and odor complaints. Booster chlorination can be a possible solution in this regard where additional chlorine dosages are applied where free residual chlorine concentration is less or zero. However, that requires optimization studies to balance various issues related to over chlorination including higher cost related to installation and operation, higher DBPs, and taste and odor complaints. These optimization studies can not only help us in selecting dosages but also can help us in various other aspects including locating booster stations, deciding number of stations, and pumping scheduling. Unlike other optimization studies, booster chlorination‐related optimization studies also require appropriate variables, kinetics, objective functions, constraints, mathematical formulation, algorithm selection, and proper optimization operation. This article will highlight details of all these steps specific to booster chlorination.
