I know you all have been waiting with baited breath to find out the in's and out's of the last two considerations when evaluating a large diameter flow thermoplastic sewer solution. To recap, typically, the larger diameters tend to have far less directional changes and lateral connections. Also, interceptors tend to have deeper heights-of-cover in gravity flow applications. Many interceptors are designed to flow 50% to 70% full, with minimal slope, deep covers, and within groundwater (requiring dewatering installation). It is also not unusual for new interceptors/trunks to be miles of pipe using several diameters.

The need for large and ultra-large sanitary sewers is growing as community populations and conveyance flow requirements increase. Many expert studies have estimated that the sanitary sewer market will grow at a 6% compound annual growth rate (CAGR) in the coming years. With this growth, alternative materials, such as thermoplastics, are being designed more frequently due to the corrosive sanitary sewer environment.

Continuing to address some of the recently asked questions regarding reline, I wanted to respond to a few other questions that may warrant a little more time and attention. I hope these responses prove helpful and aid in your next reline/rehabilitation project opportunity. Should you have any other questions on the reline process, please reach out to us!

A Response to Frequently Asked Reline Grouting Questions

In the smash hit 1987 film, The Princess Bride, Princess Buttercup violently pushes her beloved Westley down an endlessly sloped hillside. We know what you’re thinking: “Could a corrugated metal pipe possibly be placed underneath such a sloped hill? Inconceivable!” This question has plagued men and women alike since the invention of corrugated steel pipe. Thankfully, AASHTO and ASTM have spelled out a solution for us all. And that solution, my friends, is graphically depicted below, which will be elaborated on…

A-2000™ PVC has been on the Florida Department of Transportation (FDOT) Optional Material for 100-year design life since 2003 and has been used for years in Florida and across the country as a direct equivalent to reinforced concrete pipe (RCP) in most storm sewer applications.

Contech Slotted Drain™ is used effectively to intercept storm water runoff from wide, flat areas such as parking lots, municipal streets, highways, and airport runways and taxiways. In these installations, the slotted drain is placed transverse to the direction of storm water flow or snow melt runoff. The open grate intercepts all the flow uniformly along the entire length of the drain.

Projects have many phases to them throughout their lifespan from the time of their initial conception until their completion. They may span months or even years over the course of the design, permitting, procurement, installation, and inspection work that is associated with the project. Great attention is paid to ensure that each facet of the project is carried out in an accurate, timely, and cost-effective manner. Once final approval and payment is made, we often consider it “case closed” and move on to other work.

“Wow, I don’t even know what you all do but I’d like to work for a company like that!” said the waitress after she overheard the team recounting short stories

As engineers in the pipe industry, we see the results of a lot of pipe projects. Fortunately, the vast majority of the installations are successful and result
