Which of the following is a feature in the Central River?

The presence of a water treatment plant is a significant feature in the Central River area. Water treatment plants are essential infrastructure facilities that process and purify water for safe drinking and other uses, ensuring the health and well-being of the surrounding population. These plants play a crucial role in maintaining water quality, managing pollution, and supporting sustainable water supply systems in urban and rural environments.

The other options represent features that, while they may be relevant to the broader landscape or community, do not directly relate to the notable geographic or infrastructural characteristics of the Central River itself, which focuses more on water management and environmental health. For instance, rowing clubs and bridges contribute to recreational and transportation aspects but are not central to the core function of the river as a resource for drinking water and sanitation.
