Trench, Storm and Sanitary Drains

Residential Vs. Industrial Drains

  • Drains in your home are typically used to catch liquids (mostly for waste and grey water) and can be found in smaller areas such as the shower, bathtubs, and sinks. 
  • Drains in manufacturing are found in tighter spaces and catch more fluids. They can be a hazard to the work area and cause structural damage.

Trench Drains: The Basics

Trench drains are elongated surface drains used to remove fluids from a specific area, such as a driveway, sidewalk, beneath an un-guttered roof and other similar areas where water can collect. Trench drains work well to protect areas from erosion, and are a very effective tool in overall flooding control. Trench drains are used to remove the following types of fluids:

  • Waste water, like snow and slush
  • Fluids, like machine or CNC coolant
  • Chemicals, like cleaning products 

Trench drains are used in situations to avoid standing water and optionally separate the water from the main drain. They cover a much larger area than a traditional floor drain, and are flush with the floor- typically on a downward slope. In order to install a trench drain, you will need to create a trench for the drain and other drainage elements to be placed into. Normally, trench drains are installed in concrete or other hard surfaces. Depending on application, trench drains are made from plastic, galvanized steel, cast iron, polymer or HDPE. Additionally, trench drains can have a filter to capture debris and certain fluids like oil and grease.

The Value of A Trench Drain

Trench drains allow for a better work area, keeping them cleaner and allowing for flatter floors. They can cover much larger areas in comparison to floor drains and decrease the chance of contamination in food processing buildings. 

Trench Drain Applications:

  • Garages: Makes it easier to wash vehicles and remove snow, slush and mud
  • Manufacturing Facilities: Disposing of chemical or cleaning product runoff.
  • Food Processing Facilities: Easily dispose of potentially harmful bacteria found in meat processing and reduce contamination.
  • Sports fields and roads: To ensure surfaces don’t pool water and quickly dry out.

 

Storm and Sanitary Drains

Collects storm water or rainwater runoff, from all impermeable surfaces (buildings, roads, parking lots, etc.) and flows untreated to local bodies of water (ex/ rivers and lakes).

 

Storm Drain

Collects storm water or rainwater runoff, from all impermeable surfaces (buildings, roads, parking lots, etc.) and flows untreated to local bodies of water (ex/ rivers and lakes).

Sanitary Drain

Collects sewage from homes and businesses and conveys it through a network of pipes and pump stations to treatment plants, where the water is treated before being released into local bodies of water.

Combined and Seperate Drain Systems

Combined Systems – In many cities,  stormwater and sanitary sewers are combined into a single pipe – the combined sewer. Many areas that were built before the 1950’s are serviced by this type of sewer (for example, Toronto). 

Separate Systems – The installation of a twinned pipe system eliminates overflows of untreated wastewater, providing immediate environmental benefits to local bodies of water, where the wastewater is otherwise released, during large rain events.

Quick Recap

  • Trench drains have more advantages over traditional drainage systems, such as more applications and overall improvement to workspace safety and cleanliness.
  • Storm drains carry rain and snow back into lakes and bodies of water.
  • Sanitary drains carry waste to water treatment plants.
