The Benefits of an Above Ground Trailer Septic Holding Tank

No Excavation Needed: Choosing an above ground holding tank eliminates the need for excavation. Our 300 USG (US Gallon) single-compartment low profile holding tank is only 16” tall. The perfect size to slide under a trailer, mobile home, or cottage. It can fit in the space between the ground and the floor.
No Leach Field: Because this is a holding tank, there is no leach field required to process waste.
Reduced Plumbing: Plumbing into this holding tank is easy, simply slide the tank to the location you want, and run an outlet from your trailer (cabin, cottage etc.) into the top of the tank. You pick where the tank goes, and you pick where the inlet goes. This flexibility means you can install this tank with one outlet pipe and some PVC cement or a bulkhead inlet. The tank has a bulkhead outlet for a valve placement that can help with emptying. Meaning this entire installation can be completed with as few as three pieces of plumbing. By using bulkheads you can easily disconnect the tank from your trailer and move it in the back of your truck if needed.
Drastically Reduced Cost: A dual-compartment septic system with a leach field averages between $18,000 and $35,000 in Ontario. Thanks to the ease of installation, eliminated excavation, reduced plumbing costs, and affordable tank price, a project using this 300 USG tank can be completed for under $2,000. This solution makes waste removal possible for many cabins and trailers in a way that traditional septic systems can’t.

How Often Does 300 USG Need to be Emptied?

There are a huge range of factors that will skew this number, such as the number of facilities (showers, bathrooms, sinks) and the number of people using them. A small tank like this is most common in a trailer park, where a waste removal service is offered on a regular (weekly) basis. It’s also a great choice for hunting cabins with a small amount of indoor plumbing. For permanent use or larger requirements, the solution is likely a below ground holding tank with a larger capacity, or a dual-compartment septic system.

Generally speaking, the best bet is to be aware of how much wastewater is being produced, and plan accordingly. The average person will create between 40-90 gallons of wastewater daily with routine living. Conservation efforts and awareness can help reduce this amount.

The Difference Between Holding Tanks and Septic Tanks

There is one primary difference between a holding tank and a septic tank. A holding tank is a single-compartment storage container for waste that needs to be manually emptied. A septic tank is a dual-compartment tank that processes and distributes waste into a leach field.

The dual-compartment septic tank system is what most people picture when they think about septic tank installations. You can explore the components of this type of septic system here. However, a single-compartment holding tank can be the perfect solution. Especially for trailers, cottages, and cabins with fewer facilities or limited use.

  This place is amazing for your needs. I have bought drainage supplies from them and last week I needed some materials for a municipal water line. They didn't have it but they kindly directed to me another supplier that did. Without their help I would not have got the job done.

  Love this place and I always enjoy the reception I get from the others and patrons. This is the store  provides all of the special fittings for my irrigation setups. There's not a problem they can't fix for you in that respect but they are so much more.

  Picked up some 3" big O pipe with fittings and explored the store. Amazing selection of great quality agricultural and landscape products. Both this and my previous experience with Kyle and other staff has been outstanding. It was almost an 80 minute drive for me but knowing I can get things there that I probably cannot find to many other places and the food staff I will come back as the need arises and will refer others when I can.

  This is a well run business with polite, professional staff willing and able to answer any questions regarding piping, fittings landscape material... the list is long.  The inventory of various fittings, culvert and piping is extensive... nothing in the area like this business. Kyle is a keen manager who ensures everyone is treated well and gets what they need... he knows his product lines well.  George knows his pipe fittings and is able to draw from an extensive knowledgeable background to satisfy any configuration.

  For starters, great phone reception from Julia - friendly and knowledgeable. I placed an order for a truck load of mulch to be delivered on a Friday afternoon but we were not going to to be home at the time. I laid a tarp on my driveway with bricks to keep it in place.  I requested the load be dumped on one side of the tarp so when I got home I could fold it over the mulch because rain was forecasted. I actually got a call from Moe, the driver, telling me that my tarp was a bit too small to cover all the mulch. He came up with the idea to "borrow" a tarp I had on my old utility  trailer to cover the rest of the load. When I got home I found my mulch completely covered with bricks spread all over the tarps.  Who does that in this day and age? Amazing service!  I am for sure buying from these guys again!
