“…Wastewater treatment plants that have high capacity use factors (Guerrini et al, 2017) are less flexible compared to oversized wastewater treatment plants in terms of the feasibility of storing the wastewater to delay treatment. Influent flow rates may highly fluctuate such that the maximum‐to‐minimum ratio of influent flow rates can be as high as 4:1 (Hamitlon, Braun, Dare, Koopman, & Svoronos, 2006) (e.g., as demonstrated by the flow rate pattern of the Hyperion wastewater treatment plant located in Los Angeles, CA [Poosti, Lewis, Sereno, Redd, & Abkian, 2002]).…”

Leveraging the potential flexibility of large electrical loads has become an attractive option for maintaining grid reliability, especially in electric grids with high penetrations of variable renewable energy. The water sector is a particularly attractive option for demand‐side flexibility due to its vast water storage infrastructure, large interruptible pumping loads, and energy generation opportunities. Shifting the timing of water supply and wastewater utility operations can reduce peak load and temporally align energy‐consuming activities with periods of cheap electricity prices and/or high renewable energy generation. This paper presents a general overview of demand‐side management strategies in water and wastewater systems, focusing primarily on demand‐response measures. We find that while there is consensus in the literature about the potential for water systems to provide flexible demand‐side management services, there is a need for developing comprehensive water‐energy models to examine the value of load management as a source of revenue for water utilities and as a source of flexibility for the electric grid. More experimental studies and simulation efforts are also needed to address the technical complexities and water quality concerns associated with interrupting water and wastewater utility operations.

“…The robust, simple design of the Archimedes screw allows it to transport solids and fluids between its blades without obstruction-making it advantageous for a variety of implementations [23]. It has functioned as a water [24] and wastewater pump [25], a conveyor for granular solids (ie, grains) [26,27], a fish ladder [28][29][30], a drive mechanism for amphibious vehicles [31], for injection molding [32], land reclamation [33], heart valve replacements [34], and for hydropower generation [35]. Note that this paper focuses on applications involving water conveyance.…”

Archimedes screws have been used as pumps since antiquity and have more recently been implemented in micro-hydropower plants as an ecologically advantageous technology. They are regarded as a hydropower technology with lower environmental impact since they allow safe passage of aquatic flora and fauna through slow turning, widely spaced blades during operation. Archimedes screw generators (ASGs) operate at river-to-wire efficiencies at approximately 75% with relatively low installation and maintenance costs when compared to other hydropower technologies of the same scale. ASGs are relatively simple and cost-efficient to manufacture-simple enough to create in the seventh century BCE. Modern manufacturing techniques for sheet metal and fabrication have refined ASG production. The literature contains various parametric models for predicting screw power output, and more recent numerical simulations have provided insight into the fluid mechanics of screw generators. The knowledge gained from these studies has allowed researchers to suggest more optimal designs for Archimedes screws. However, much can be done to further improve the accuracy of power prediction models. This paper discusses the current state of the literature for ASGs, and highlights areas for future research to improve power prediction and optimization capabilities for researchers and industrial designers. Highlights• Archimedes screws are an ancient pumping technology that have more recently found use as a hydropower-producing technology.• Archimedes screw generators (ASGs) are a small-scale hydropower technology that may be installed as a run-of-river installation.• ASGs are an eco-friendly technology that allow for the safe passage of sediments, small debris, fish, and other aquatic wildlife through their flights during operation.• There are few experiments and computational fluid dynamic simulations that have sought to extend the literature's data on ASG operation.• Current performance models for ASGs lack robust validation to be properly implemented in power plant design.

“…Although LADWP's 2015 UWMP (LADWP 2016) predicts an increasing influent flow to Hyperion plant (which will increase electricity use), the co-generation plant capacity is still large enough to meet all electricity demand. We calculated the peak electricity demand of Hyperion using a representative influent flow curve shown in Figure 50 from Poosti et al (2002). It is estimated that the peak load of this facility will increase to 31 MW by 2050, which is still less than its on-site generation capacity.…”
