The quality of water in our rivers, lakes, and streams is important for many reasons. People rely on water for drinking, cooking, bathing and irrigation; water is also essential for industry and agriculture. Healthy aquatic ecosystems depend on clean water and poor water quality can adversely affect human health. Consequently, water infrastructure in its various…

Trenching is a common civil engineering excavation method used in pipeline, sewerage, drainage and cable trench construction. The process involves digging a long, narrow trench into the ground with a trencher or backhoe to install utility lines or other underground infrastructure. Trenching is a necessary step in many water infrastructure projects, as it allows for…

Green stormwater infrastructure is a type of civil engineering construction that uses natural systems to help manage runoff from urban areas, such as vegetated areas and rain gardens. This aids in the reduction of water quality impacts, the control of flooding and the overall improvement of water management in communities. In addition to these advantages,…

Storms and major flooding are perennial concerns for many people in cities and towns across Australia. Heavy rainfalls can cause significant damage to businesses, parks, agriculture and people’s livelihoods, costing millions of dollars in repairs and disrupting the lives of thousands of people. While flooding cannot always be avoided – for example, in the event…

When we pass by infrastructure, we frequently overlook its brilliance. On rare occasions, however, we can take a step back and admire the scale of the construction and the meticulous planning that went into it. Concrete culverts are a prime example of underappreciated infrastructure. They are commonly used to allow drainage and water bodies to…

Sewer systems play a vital role in our society as they work to drain away the waste generated in our domestic and commercial buildings. Vacuum, gravity and pressure are the three most common types of major sewage systems, each of which operates differently and is installed differently. What is a sewer main? The main sewer is a…

Stormwater infrastructure is essential to the health and well-being of our communities and the environment. The fundamental goal of stormwater infrastructure and management is to minimise and contain runoff as much as possible while also eliminating impurities to improve water quality. Stormwater runoff is a significant source of water pollution in urban areas and can…

Water is necessary for daily life, as well as for our health, hygiene and community living. Local water treatment plants process water to ensure a constant supply of high-quality, safe drinking water. The water treatment process may alter slightly based on the plant’s technology, but the core principles remain the same. Coagulation-flocculation Coagulation-flocculation is the…

The construction of a pipeline is a process that involves numerous stages of organised and coordinated activities that are in place to develop a functional pipeline system. Once the pipeline system is assembled, any pipeline construction in Australia needs to be inspected, tested and commissioned using well-established procedures. Key construction activities include: Preparations & clearing Trenching for below…

In civil engineering, earthwork considerations are generally the first step in the construction process for both the engineers and architects, especially if they are building a structure from scratch. Civil construction from the ground up is a highly detailed process in the first place and any physical restrictions of the chosen landscape can present challenges.…
