What are Sewage Lagoons?

Sewage lagoons are basically large ponds or reservoirs where sewage or effluent from a known sewage system flows. Sewage lagoons also go by the name effluent ponds. In a sewage lagoon the effluent and sewage are broken down with the help of bacteria. The process is also aided by sunlight and wind. The sun provides light, warmth and oxygen to the water. This is a necessity in order to foster the growth of bacteria necessary for breakdown. The light, heat, and oxygen also help in the growth of algae in the water. This is the organism responsible for giving lagoons its greenish color. Algae help in breaking down the effluent and the sewage. Lagoons and reservoirs need to be lined by sewage lagoon liners in order to prevent leaks to the groundwater beneath. In a typical lagoon, wastewater is treated via a combination of physical, biological and chemical processes. Most of the treatment occurs naturally however, some systems utilize aeration devices that add oxygen to the wastewater.

Role of Lagoon Liners and Reservoir Liners

Sewage lagoon liners work by helping control wastewater seepage, an important aspect for the maintenance of drinking water quality. Raw sewage and wastewater sludge present in septic tanks, lagoons, reservoirs, and sewer lines have the potential to leak, overflow and eventually seep into the drinking water during the wastewater treatment cycle. This elevates the risk of toxic substances such as contaminants, nitrates, bacteria and other materials entering the drinking water supply.

If you do not have reliable lagoon liners you risk the chance of wastewater seepage due to:

Improperly Lined Lagoons – This is by far one of the most common causes of wastewater seepage. Leaks in sewage lagoon liners can result in wastewater to penetrate deep into the ground and eventually contaminating clean water supplies. The leaks may be caused by a variety of reasons namely punctured liners, overflow, or the use of substandard lining material. The use of our tried and tested lagoon liners can help reduce the possibility of wastewater seepage on your lagoon systems.

Reduced Capacity of the Lagoon – the capacity of lagoon systems is greatly influenced by the presence of the buildup of sludge. The more sludge present, the less capacity of the lagoon and the greater the risk of wastewater eventually seeping into precious clean groundwater and streams because of the lack of space for it to be contained.

Surplus Wastewater and Contaminants – There are instances when the volume of wastewater that undergoes processing is really high resulting in a larger concentration of contaminants that can cause seepage. The result is a slowing down of movement of the wastewater through the system, causing it to remain more in place longer and hence the possibility of seepage into the surrounding water also increases.

IEC Covers’ Sewage Lagoon Liners to the Rescue

Our top-of-the-line geosynthetic lagoon liners may be used to help prevent seepage during the wastewater treatment process. We can fabricate sewage lagoon liners in any specification and then installed them on-site to help minimize the possibility of wastewater seepage. We use a variety of different materials for our lagoon liners and we can help you choose the right one to suit your needs and applications.

General Features of our Sewage Lagoon Liners

  • Excellent tear and puncture resistance properties
  • Approved for use in potable water
  • Safe for plant and fish life
  • Offers superior ultraviolet light resistance
  • Excellent at prevention of water loss in your lagoons
  • Can immensely help in soil and erosion control
IEC Covers’ lagoon liners offer excellent impermeability features that can help control water loss and seepage that can cause water contamination. There is no doubt that a lot of lagoons are built in areas where there is also a local water table. While wastewater undergoes natural filtration as it flows through the different layers of soil and rock beneath the ground, it requires spreading through a lot of material before becoming potable once more. The presence of a high water table beneath a lagoon may allow sewage to come in even before it has the chance of getting filtered properly. IEC Covers sewage lagoon liners can provide the level of impermeability you need in order to control potential seepage.
