Septic Tanks

Premier Plastics Inc. has 25 years’ experience with engineering design and installation of below ground septic tank solutions. The key design element of poly septic tanks for below ground use is the resistance to compression buckling or pressure from the outside in. This is opposite to above ground tanks where the pressure is from the inside out. The key design element is the tensile strength of the material. To resist buckling, below ground tanks have a thicker wall and are typically spherical in shape with light ribbing, or non-spherical (loaf shape) with heavy ribbing. The small flat triangular ribbing design of our SuperTanks holds the stresses in-line with the flat surfaces which result in a profile that resists pressure equally from the top, the sides, and the ends of the tank. No others tank design can claim this.

Each plastic septic tank is delivered to you completely ready for service.

  • Inlet and outlet connections are pre-plumbed for 4” sewer pipe.
  • Two chamber dividing walls, when required, are also installed.
  • No water ballast is required during the installation process.
  • Polyethylene septic tanks are molded in all one piece and are totally watertight from the factory.
  • Access openings can accommodate various styles of riser pipe.

Be sure to read the Installation Instructions and return the warranty card provided with each tank.

"Hey John, nice picture of my site. That was a good job. It turned out very well".

J.J. – Sequim, WA

“The Flout dosing system works great. The Installer was very impressed with how easy it was to install and the Owner was happy with the cost and no electricity. I will use this product every chance I get.

We ended up with 5’ of residual head (3’ of squirt height out of cap)

Here are some pic’s

Thanks for everything,”

D.R. – Powell River, BC

“Attached are the two photos showing the squirt height from my first installation of a flout chamber. As you can see in the one photo the squirt height is greater than 24 inches. The chamber is hard to see but is located just behind the pickup about eighty feet from the field with a height above the field of about 4 feet. It works great. Thanks”

S.C. – Denman Island, BC

“Just wanted to tell you I designed a system around the flout for the Affordable Housing  Association here on Denman and it worked like a charm. Your worksheet worked well and the dose pressured up the field evenly for about 3 minutes. I called the person who will be living in the house, he went and saw the squirt test and was impressed with the whole idea of dosing with no electricity as he is the one who will be paying the bills!
Cheers and thanks,”

T.P. – Canton, OH

“We actually chose the option with the 2” transport  pipe without the vent, instead of 3”.  It worked just as the tables predicted.  Thank you very much!  You took the mystery out of the design.  As far as the State Health Department is concerned, Rebecca Fugit oversees the sewage program at the state.”

B.S. – Nanaimo, BC

“Here are the pictures from the Prospect Road project. Thanks again for all your design help. As you know, I was skeptical as to the function and design of this new technology, but I was extremely impressed with how it turned out, and the incredible squirt height that it provided. I will be using this method of pressurizing a septic field on my next available sewage system design.
Thanks again for all your excellent help.”

D.P. – Quadra Island, BC

“Thank you John. The install went very well. (I haven’t installed the counter yet.) Easy to set up and it works great! It’s a marvel. I am now officially your biggest fan!”

S.C. – Hornby Island, BC

“50 orifices at 3/16”, 7.5’ from top of dosing tank to field, 51’ of 2” PVC total transport. When I did your worksheet, it all seemed like it would work and it works really well!”

L.M. – Vacaville, CA

“So the flout did function with a 7-foot residual score as expected then it might have been an airlock so with that vent standpipe we were to mitigate that problem, got our final inspection to pass and are on the second flout install which will be going in next week. In another jurisdiction I will be specifying the same setup on a hillside project and hope to get a second order in to you before the holiday rush”

T.L. – Kelowna, BC

“Had a 24in squirt at project with about a 5ft head. Can email pictures later.”

D.P. – Quadra Island, BC

“Everything worked great! Still can’t believe how simple it is and how much it saves the customer. Sent a video along I thought you might like. Thanks again for all your support. And by the way, I pulled the manager and assistant manager at Andrew Sheret out to look at your tank and give them the big sales pitch. I’m working for ya.”

B.R. – Vernon, BC

“The Flout did exceptionally well. I may be giving a talk to the membership at the WCOWMA AGM.”

I.R. – Thetis Island, BC

“I have tried the flout program you sent me previously on a couple systems, one is constructed and it worked well for that.”

D.P. – Quadra Island, BC

“So here is the squirt test on my job that you and I discussed. Worked just as you said. The black ring on the shovel handle is 2’ off the ground. It still amazes me. (Even though I didn’t hoop and holler this time)”

B.E. – Kootenays, BC

“I used the spreadsheet Gravity Powered Pressure Dosing System Calculator for the pressurized system and it works very well. I got it from the website. Thanks again.”

R.D. – Lake Country, BC

“It was good to see you again John. We like your products and will continue to use them.”

T.S. – Winlaw, BC


Nice Job on the GRAVITY-2017-Gravity-Powered-Pressure-Dosing-Calculator-for-Septic-Fields-2017-Revised

Super easy. Thanks

Hi John, I wanted to write a thank you for the support you have given me. I’ve pulled the plug on my business after 40 years but I want to acknowledge those that have helped me along the way, you being one of them. It was a pleasure finding you. I thought you went above and beyond in support for my business and I really appreciate your help.
