Combined Sewer refers to a type of wastewater management system that collects both sewage and stormwater in a single pipe network. This skill involves understanding the design, operation, and maintenance of such systems to effectively manage and treat combined flows, particularly during heavy rainfall events. Knowledge of Combined Sewer is used to mitigate flooding, reduce pollution, and ensure compliance with environmental regulations by implementing appropriate treatment processes and infrastructure improvements.

Green Infrastructure refers to a network of natural and semi-natural systems that provide environmental, social, and economic benefits. This skill encompasses the design and implementation of practices such as green roofs, permeable pavements, and urban forests to manage stormwater, improve air quality, and enhance biodiversity. Knowledge of Green Infrastructure is used to create sustainable urban environments by integrating natural processes into urban planning and development, thereby mitigating the impacts of climate change and urbanization.

Land-use planning is the process of allocating and regulating the use of land in order to maximize its potential and minimize any negative impact on the environment, economy or social well-being. It involves analyzing land use patterns and trends, identifying potential development opportunities and constraints, and developing policies and regulations that guide the use of land. Land-use planners must have knowledge of zoning regulations, environmental impact assessments, transportation planning, urban design and community outreach, among other things. They work with government agencies, developers, environmental groups, and other stakeholders to ensure that land use decisions are fair, transparent and sustainable.

Transport Engineering refers to the planning, design, and operation of transportation systems and infrastructure, aimed at facilitating the efficient movement of people and goods. This skill encompasses the analysis of traffic patterns, the development of transportation models, and the implementation of safety measures to enhance mobility. Knowledge of Transport Engineering is used to optimize transportation networks, reduce congestion, and improve accessibility, thereby contributing to sustainable urban development and economic growth.

Water/Wastewater Engineering is a specialized field within civil engineering that focuses on the design and management of water supply and wastewater treatment systems. This includes the collection, treatment, and distribution of potable water, as well as the treatment and disposal of wastewater. Water/Wastewater engineers also play a critical role in ensuring public health and safety by developing and implementing systems that meet regulatory standards and protect the environment.
