New Challenges

Instrumentation, control and automation (ICA) are key technologies in modern water and wastewater systems. Ever present disturbances make it necessary to automatically attenuate their consequences. A wastewater treatment system is load driven, while a water distribution system is demand driven. Despite the variability the system outputs have to be satisfactory. Economic realities encourages the application of ICA to make a maximum use of plant capacities. An increasing complexity of competing processes in a modern nutrient removal plant makes more elaborate control necessary. The final goal of protecting the environmental resources necessitates an integrated view of several interdependent systems, the collection, transport and treatment processes. In this integrating development ICA will be a decisive technology.

Instrumentation, control and automation (ICA) are key technologies in modern water and wastewater systems. Despite the variability of the influents the system outputs have to be satisfactory. Economic realities and new water directives encourage the application of ICA to make a maximum use of plant and other storage capacities. The final goal of protecting the environmental resources necessitates an integrated view of several interdependent systems, including the collection, transport and treatment processes. In this integrating development ICA will be a decisive technology.

Abstract Objective The aim of this study was to design a domestic water temperature, pH and turbidity monitoring system that could constantly log temperature, pH and turbidity of water and give alerts in case the parameters are outside the acceptable limits for potable water. Results The system was designed, assembled and performed as expected. The study indicates that the proposed and designed system outperforms the existing manual monitoring system as it can constantly track and store changes in water quality. This could be used to prepare better treatment processes as well as identify problems in the water distribution system early enough.

Operation And Management

The resilience of a water distribution system (WDS) is defined as its ability to prepare, respond to, and recover from a catastrophic failure event such as an earthquake or intentional contamination. Robustness (ROB), one of the components of resilience, is the ability to maintain functionality to meet customer demands. Recently, the traditional probability-based system performance perspective has begun to shift toward the ROB and system performance variation point of view. This paper provides a state-of-the-art review of WDS ROB-based approaches proposed in three research categories: Design, operation, and management. While few pioneering works have been published in the latter two areas, an ROB indicator was proposed and thoroughly investigated for WDS design. Then, some future works are recommended in each of the three domains to promote developments in WDS ROB. Finally, a brief summary of this paper is presented, from which the final conclusions of the state-of-the-art review and recommendations are drawn. The new paradigm of WDS ROB-based design, operation, and management is in its infant stage and should be carved out in future studies.

Natural organic matter (NOM) in water reacts with chlorine or other disinfectants and form hazardous disinfectant by-products (DBPs). This study aimed to detect the presence of NOM in a conventional water distribution system using UV absorbance at 254 nm as a surrogate. Two water treatment plants were selected, namely, Jalan Baharu Water Treatment Plant (JBWTP) and Lubok Buntar Water Treatment Plant (LBWTP). Aside from determining the amount of NOM, the reduction of UV254after completing the series of treatments (coagulation, flocculation, sedimentation, filtration, and disinfection) was also observed. The presence of UV254in both raw water and treated water samples confirmed the presence of NOM. The concentration of UV254recorded at JBWTP and LBWTP were 0.14 and 0.13 cm−1, respectively. After the treatment processes, the concentration was reduced to 0.04 cm−1for JBWTP and 0.03 cm−1for LBWTP. These results indicated that the water supply in both plants contains DBP precursors and implied the possibility of DBP formation in the system. Moreover, the percentage reduction of UV254recorded were 69% and 75% for JBWTP and LBWTP, respectively.

Rehabilitation Strategy

The aging process in water distribution system is one of the main drivers for the reduction of performances in water distribution systems. Furthermore, this conditions usually imply an increase in the maintenance costs that the water utilities have to sustain. In this situation it is required to undertake programmatic strategies in order to guarantee the highest benefit for both the final users and the water companies. An optimal rehabilitation strategy has been proposed in order to take into account the regulatory schemes that have to be abided at the national level, in the water industry.

The Maule Mw 8.8 earthquake of 27 February 2010 impacted a number of water and wastewater lifelines. Ground shaking and liquefaction heavily damaged the Essbio water and wastewater systems, particularly in Concepción. Ground shaking destroyed more than 70 elevated water tanks in rural water systems built by the national government. A fire water tank collapsed at the Santiago Airport. There was damage to canals. Despite more than 3,000 repairs to other types of water pipe, the high-density polyethylene pipe used in the Concepción water distribution system was undamaged.
