PolyJohn 300 Gallon Holding Tank

PolyJohn 300 Gallon Holding Tank

Hi there! My name is Jamie, and I'm here to show you about one of our products here today. We have here our 300 gallon holding tank, it features a capability of holding 300 gallons, its 95" in length, 53 1/2" wide, and 16" tall. It features stacking lugs so if you have several tanks that if you need to stack on top of one another they do stack. It has 6 different ports that you can connect to - this port here is opened up from the factory; however, if you need other ports for your configuration, you simply take a 3" hole saw and drill out the port that you need. These ports are connected to your PVC plumbing through a rubber connector like this. The rubber connectors are available in different configurations, we have an elbow here but they have wyes and simple connectors. All of our holding tanks are 200 gallon holding tanks - the 300 gallon holding tanks can be daisy-chained together, meaning they can be hooked up in series to double or triple their capacity. You see this is our pewter grey configuration, we also carry this in a natural, which is translucent. These tanks are usually used to hold waste water, however they can be used to hold fresh water. The materials that we use are FDA compliant, so there's no worries there. If you'd like more information, please visit our website as shown after this video. Thank you for your time.

PolyJohn HT01-0300 Details

Complete your portable restroom area with this PolyJohn HT01-0300 grey 300 gallon holding tank. This discrete holding tank provides a sanitary receptacle for your portable restroom where indoor plumbing is not available. This holding tank can be used for above ground waste storage or fresh water storage. Each holding tank is manufactured using a linear low-density polyethylene, hexane copolymer resin, making it an extremely durable option for long-term waste storage. This resin material has excellent processabilities, outstanding dimensional control, low warpage, excellent environmental stress crack resistance (ESCR), and long-term, ultraviolet (UV) stabilization. It's the heavy-duty solution to keeping waste safely contained without the threat of cracks, leaks, or spills. The large capacity makes it perfect for use in a portable restroom with long-term storage, and a 1/4" nominal wall thickness guarantees dependability. Additionally, its FDA food grade compliant resin and grey pigment provide extra discrete storage of waste.

This holding tank has a 3" fitting to connect it to a portable restroom. It eliminates the use of threaded and solvent-cemented conventional plumbing fittings - which are usually discarded after each use - by utilizing Fernco® flexible rubber couplings instead. Fernco® couplings are manufactured from tough, elastomeric polyvinyl chloride (PVC) and are unaffected by soil conditions. They are reusable and resistant to chemicals, UV rays, fungus growth, and normal sewer gasses. The clamps, band screw, and housing are all made from 300 series stainless steel. Typically, the distance from the holding tank to the restroom / sink is around 3 - 6 feet, but this could vary depending on the slope of the tank. To clean / pump out your unit, it is recommended to seek out a service contractor. This tank must be monitored to know when it needs service.

This tank's specialized design means it can be used with many of PolyJohn's portable restrooms or sinks. It even has a discrete appearance perfect for use around portable restrooms or portable wash stations. Regardless of whether it is used underneath a trailer, outside of a portable restroom, or beside a portable wash station, this holding tank is sure to give you a convenient and discrete way to store waste.

PolyJohn sets the standard for the sanitation industry and is the leading manufacturer of portable restrooms. Their products are made for high traffic areas such as commercial worksites, festivals, and fairs. Most importantly, each PolyJohn is designed to be easy to clean and maintain. Regardless of where you need them, PolyJohn's products are built to withstand years of use.
