The intake tower is a reinforced concrete construction founded at a lower elevation than the dam, connected to the dam crest through an access bridge. In terms of mechanical equipment, the intake tower includes intakes, trash racks, bulkhead gates, gates and auxiliary maneuvering installations.

Passaúna Reservoir is a valley-shaped drinking water reservoir with a surface area of 9 km2, a volume of ∼60 × 106 m3, a length of 11 km, and a maximum depth of 15 m (Carneiro et al. 2016). With a production rate of ∼1.8 m3 s−1, it provides the water supply for 650 000 inhabitants of the western region of Curitiba and 3 neighboring cities (SANEPAR 2013). The Passaúna River enters the reservoir at the northern end through a forebay, which has a geometrical constriction due to the embankment of a bridge (Ferraria Bridge). This region of ∼0.28 km² area and average depth of 1 m is called the Buffer because it attenuates variations of the river inflow. The intake tower of the treatment facility is located close to the reservoir bank, and water is abstracted near the surface. The reservoir outflows are a spillway and a bottom outlet at the dam (Fig. 1).
Seismic Damage of Submerged Intake Tower under the Sequence of Mainshocks and Aftershocks

In this section, the nonlinear dynamic response of the reinforced intake tower–reservoir–foundation system subjected to the aforementioned seismic sequences is discussed. This study focuses on the following engineering design parameters (EDPs): tensile and compressive damage of concrete, the plastic strain of the reinforcement, dissipated energy caused by the concrete damage and the nonlinear behavior of reinforcement, residual drift, and displacement response. Also, the relationships between EDPs and earthquake IMs is investigated in the next section.

In Serra Azul reservoir, 3 water withdrawal depths are possible in the water intake tower. The minimum water level for water withdrawal, known as dead storage, is 32 m, and the water level was below this limit from August 2014 to January 2016 (Table 3). This period included 525 d below the lowest withdrawal elevation, revealing the severity of the water scarcity. During this period, the water stored in the reservoir could only be withdrawn by pumping.
