Risers allow easy access from the surface to tanks installed underground. Risers must be secured and sealed to the top of the tank to prevent the intrusion of run-off or ground water. Riser lids should project a few inches above the ground surface to prevent debris entering the tank when opened. Lids must be screwed down at all times. We offer three options for risers:

ULTRARIB Pipe Riser

Cutting UltraRib Pipe

Cutting UltraRib Pipe

This saw is easy to use and makes a very clean and smooth cut.  A Single cut can take no more than 20 seconds with no clean up required.  See YouTube video.

ULTRARIB RISERS – DISCUSSION  

We recommend our customers use 24” nominal dia. UltraRib pipe risers for all models of PREMIER underground water and septic tanks.

UltraRib riser sections are more robust and far superior long term than many other tank riser designs currently in the marketplace.  The rigidity of the ribbed construction is very resistant to deflection from uneven backfill pressure and settling.  The ability of UltraRib pipe to hold its shape regardless of riser height helps the access opening in the tank (the structural weak point in any tank) stay round and level regardless of ground pressure and potential deformation over time.  Molded lids supplied with the tanks are not required  to help maintain stability of the opening and can be recycled.  Also, the sealed drop-on and screw-down heavy duty PolyLok lid will always be easy to lift off and put back during periodic service.

The riser height can be cut as one piece to within 1.5” of required height.  One complete guided cut takes 20 seconds with a small customized  circular saw. For most PREMIER PLASTICS’ underground tanks only two components are needed – the riser and the lid. No adapter ring is needed at the neck of the tank opening or at the lid.  The slip joint onto the tank is sealed and secured with E6100 adhesive (for polyethylene).  Silicone sealant will not stick to polyethylene.  4 – 6 lateral SS screws keep the riser in place whilst setting up.  UltraRib to UltraRib connector rings can reduce wastage from off-cuts to zero.  Field time is greatly reduced.

Our aim for our customers is to improve the overall long-term quality and value of septic installations using PREMIER SEPTIC TANKS.

Testimonials

  • “I just want to say I am impressed by the strength of this tank and will continue to use Premier tanks for my septic installations. (Please continue to make them tough.)”

  • “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.”
