Drainage is an essential part of a construction project. It is necessary to avoid any flooding or other damages in any structures and its surrounding areas. One type of drainage is subsoil drainage. It is generally used to improve the ground's stability, lower or minimise the moisture content of the site, and for landscaping purposes, can be used to enhance its horticultural properties. Highway drainage is an example of surface water drainage. The installation of drainage during road construction will prevent excess water or moisture from accumulating on or within the site.

When it comes to drainage, gravity usually does the work. Water and waste go into a downward flow towards septic tanks or sewage treatment facilities. There are two main components in all drainage systems. The first component is the vent. Vents are needed to allow air to get inside the pipes, resulting in the water to flow. The next main component is the Traps. These are found under the sinks and take the form of an S-shaped section of pipe. Some of the remaining water which does not flow down the pipe will remain in the trap. This component also helps in preventing sewer gas from entering the home.

To create a safe and hazard-free structure, it is important to eliminate water stagnation and other associated safety and health issues. A well-designed drainage system will address these issues. But during construction, there are many variables to consider. These are installations times, costs, flow velocity, resilience, as well as lifetime maintenance costs. Below are the different types of drainage systems that you may encounter when looking to install one in your construction project:

• Swale Drains
• Point Drains
• French Drain
• Trench Drains
• High-density Polyethylene Trench Drains (HDPE Drains)
• Cast-in-place Trench Drains
• Slot Drains

A pipelayer is a worker who performs the first stages of construction. They are responsible for creating the initial groundwork by laying down the pipes which will then provide sewage disposal, drainage or water. Pipelayers cut specific lengths of pipes that will form the sewer systems. These pipes each have specifications in length and must be aligned precisely before being connected through cement, glue or welding. Besides cutting and connecting pipes, they may also dig trenches for the pipes they will install. These trenches also have their own specifications, thus requiring skill and expertise to excavate. Pipelayers are also skilled in blueprint reading.

The drainage installation costs can vary depending on the drainage system type. Below are a few drainage system types with their corresponding costs:

• Surface Swale - estimated at $.50 per square foot
• French drain - estimated at $20.00 to $30.00 per linear foot
• Drop in-let Subsurface System - estimated at $8.00 to 10.00 per linear foot
• Trench Drain - estimated at $70.00 per linear foot

For more information, you should ask your local drainage company.

Australian standards such as AS/NZS 3500.3:2018 (Plumbing and drainage, Stormwater drainage) and AS/NZS 2566.1:1998 (Buried flexible pipelines - Structural design) set specific guidelines on design, installation and testing for drainage and pipelaying projects.

These standards ensure that projects are executed to achieve longevity, safety and minimal environmental impact. Compliance is not only a best practice but also often legally mandated to ensure public safety and environmental protection.

Drainage and pipelaying services in Australia typically range from $60 to $120 per hour. However, the cost can vary based on project complexity, location and specific requirements.

In Australia, drainage pipes should typically be buried at a minimum depth of 300 mm for non-vehicular areas and at least 600 mm for areas under vehicular load, ensuring protection and proper function.

The soil type can influence drainage efficiency. For instance, sandy soils allow water to drain rapidly, while clayey soils retain water. Proper assessments ensure suitable pipe materials and design are chosen for the site conditions.

Popular materials for pipes in Australian drainage systems include PVC (polyvinyl chloride), PE (polyethylene) and vitrified clay, chosen based on the application, durability needs and soil conditions.

Using root barriers, regular maintenance and avoiding planting large trees near drainage lines can help prevent tree roots from damaging or infiltrating drainage systems.
