5 Ways Canal Linings Add Needed Outfall Protection


Outfall protection comes in some well known forms and shapes. From storm drains and storm pipes to water canals there are a couple different options when it comes to making sure outfall doesn’t contain sediment, or otherwise contribute to erosion. Preventing erosion from water runoff is important, as it can create problems at the point where it reaches a lake, river, or ocean. There are a few options when it comes to outfall protection; however, one of the most significant is canal lining.

The Advantages Of Canal Lining

Canal linings help direct the flow of water and help the control of soil erosion, as well as water absorption into the surrounding area. A canal lining plays a very important part in making sure everything works as it should. While there are many options to choose from when it comes to constructing a lining, a few benefits overall can include:

  • Reduction In Seepage. One of the main uses of canal linings is the prevention of seepage. By preventing the water from seeping into the ground, you can better control the flow, and help mitigate soil loss and erosion of the surrounding landscape. This not only helps at the outfall point, but it helps preserve the landscape every step of the way.
  • Water Logging. Water logging occurs because of seepage, and it can make the ground water table unstable. This in turn can affect the entire area and make it unsuitable for irrigation. Going hand in hand with benefit 1, this is a major issue that needs to be seriously considered.
  • Capacity. A canal lining also increases the capacity that the channel can hold. This means you can remove water in greater quantities than before without worrying about any negative effects.
  • Maintenance. Because less sediment is being eroded and dragged along, you can expect to have less maintenance overall. This also helps speed up the process by allowing water to flow more freely. Any silt that does manage to accumulate will be minuscule and easily swept away to the outfall point. Lining also helps ensure that no vegetation can grow either in or around the canal. This growth can slow down water flow and likewise cause issues in the future. Concrete linings, specifically, eliminate this problem and help keep everything moving without in depth maintenance.
  • Flooding. Lined canals can also help mitigate flooding effects by keeping water moving swiftly, meaning it will be easier to be rid of without worry of overflow. This can also be good if you accidentally release more water than intended, as you don’t have to fear it flooding the immediate area detrimentally.


Canal linings are an important component when it comes to outfall protection as they help prevent running water from eroding soil and causing issues. It can also help prevent water logging of the immediate area, as well as allowing for a larger capacity of water to flow. Along with the ease of maintenance, it’s something to consider if your company goes through a lot of water for manufacturing purposes.
