Manhole Appreciation Day, Anyone?   Much like Rodney Dangerfield who “got no respect”, by and large manholes don’t get much respect either. They’re located under the street where they are run over millions of times per year by cars, snowplows, bikes, and pedestrians. They might even be buried in a right-of-way, or covered and lost entirely. Manholes definitely fall into the category of “out of sight, out of mind”. But have you ever thought about where our collection system would be without the manhole? While “man-way” sewer access dates back to ancient Roman times, something akin to the style of today’s manhole began to appear almost 200 years ago. Throughout all of that time, while history marched on above the surface, manholes were quietly doing their job of providing access to the sewer line for inspection or cleaning, providing directional connection points, and facilitating system design and

Common Sense, Good Sense, and Sewer Sense Common sense, good sense, and sewer sense are important attributes for those of you involved in the operation, maintenance, and rehabilitation of wastewater systems. It is simply common sense to acknowledge that the manhole and lift station parts of your sewer infrastructure that are 30 to 50 years old, which had an original design life of 30 to 50 years, are probably in need of some attention. In our experience, it is good sense to rehabilitate rather than replace those structures. Why? It will solve your problems with infiltration and corrosion, but with a safer, faster, and lower-cost process. Service interruptions are minimized with rehabilitation because you won’t need to excavate. Without the need to excavate, you’ll be the hero with a minimally invasive and less disruptive solution. And, finally, the sewer sense (not the smell) part is the selection

Culvert Lining Rehab Means Better Than New at a Fraction of the Cost OBIC is best known for its work around wastewater structures such as manholes, lift stations, and WWTP facilities that help municipalities mitigate their infrastructure issues. Another infrastructure issue equally “out of sight and out of mind” is stormwater culverts. Culverts installed 30 to 50 years ago are now failing at an alarming rate. Thousands of corrugated metal culverts are so significantly rusted and deteriorated that flooding or collapsed roads are very real possibilities and scenarios. A collapsed culvert is potentially a much greater problem than a collapsed manhole, however. If that culvert is beneath a busy thoroughfare, traffic disruption could be significant and a dig and replace repair will be costly and time-consuming. A collapsed manhole can be bypassed with a pumping system and replaced in a few days. While clearly unpleasant, it pales

What are the Benefits of No-Dig Technology? The history of no-dig (trenchless) technology in the United States dates back to the mid-1970’s. OBIC’s owners have been in the no-dig business for nearly 20 years. It’s what we do. It’s how we think about wastewater rehabilitation. But just because we think that way doesn’t mean we shouldn’t slow down a little, review the basics, and “dig” into the benefits of no-dig technology. Instead of open cut excavation to gain access for repair or replacement of the structure, as the name suggests, no-dig allows for those repairs with minimal or no excavation. We’re all in the sewer business together and we do realize that there are those rare occasions when the host structure is too far gone and cannot be safely rehabilitated, making dig-and-replace the only viable solution. So outside of this situation, why do we think no-dig technology

Hidden Cost Savings with OBIC Wet Well Rehabilitation In previous blogs, we have talked about OBIC’S quick cure times providing a fast return to service. Where this benefit really manifests itself is the substantial cost savings provided for a wet well rehab project. A day in the life of a wet well rehabA typical 6’ diameter by 10’-20’ deep lift station can be fully relined by an OBIC certified installer in a single day. Depending on the circumstances, this can sometimes be done without bypassing. Below is a typical schedule for this type of wet well rehab project.8:00 a.m. OBIC certified installers isolate the station by plugging the upstream manhole. The wet well is then manually pumped down and a vac-truck is used to rinse the walls and remove any debris. 9:00 a.m. The lining technician enters the wet well and begins the surface preparation using the appropriate pressure washing

Manhole Rehabilitation Challenges Our team at OBIC has decades of experience in sewer system rehab, construction and operation. Our combined experience includes everything from collapsing sewer manholes to deteriorating pipes and everything in between. As a matter of fact, there is not much we haven’t seen, heard and rehabilitated. While we take pride in our accomplishments and enjoy telling stories of some of the most challenging projects we have tackled, we have also learned a lot over the years. It is that experience and knowledge that helps us to expertly mitigate the varying maintenance challenges facing our clients. Below is a summary of the two most common manhole rehab challenges that our installers face daily. Manhole rehab challenge #1: inflow & infiltration The first challenge that has a significant impact on manholes and sewer systems is inflow and infiltration. Although inflow and infiltration commonly begin as a very small annoyance,

What is inflow & infiltration? When groundwater or stormwater enters dedicated sanitary sewer systems, inflow & infiltration is occurring. Most inflow & infiltration, or I&I, is caused by aging infrastructure that includes manholes and sewer pipes. While this may seem like a hopeless, inevitable problem, there are steps that communities can take to protect their wastewater systems. Infiltration is when clean groundwater enters the sewer collection system. A great example of this is when heavy rain or snowmelt penetrates the ground and raises the groundwater level. That ground flow can infiltrate sewer pipes and manholes through cracks in the structure, missing or deteriorated gasket joints and leaky pipe penetrations. High water tables, or groundwater, is particularly common in coastal areas but also occurs in communities that are near lakes, rivers, ditches or wetlands. While seeping groundwater infiltration may not sound like an immediate concern, it can become

OBIC provides long-lasting, cost-effective solutions for a wide variety of industries and applications In Latin, obic is the root word for barrier. When we founded our company in 2017, we couldn’t think of a better name for our products.

Water Treatment and DistributionDrinking water distribution systems rely on metallic and concrete pipes, which are at risk for corrosion.As these systems age, concrete degradation or rust in metallic pipes begins to contaminate the drinking water that runs through

OBIC hand-injected grouts provide options for amateurs and professionals alike Underneath the streets of every city is a maze of sewer pipes, storm drains, manholes and pump stations that carry wastewater and stormwater through a strategically planned sewer system. These sewer systems are vital to protecting the environment and keeping our communities clean. Unfortunately, they are also deteriorating at a rate that is difficult for many communities to manage.According to infrastructurereportcard.org, the nation’s underground wastewater pipes are, on average, 45 years old with some systems exceeding 100 years. When you consider that the average life expectancy for these pipes is 50-100 years, it is no wonder that infiltration, or water leaking into the structure from the ground, has become a common and costly problem. Infiltration causes costly wastewater structure rehab challengesWastewater infiltration is both a short-term and long-term problem. The short-term impact is easy to calculate. According to

OBIC Pump-injected grouts stop even the toughest infiltration issues Water and wastewater rehabilitation projects inevitably share one common challenge, infiltration issues. These are often leaks that are caused by cracks, missing mortar, deteriorated gaskets, pipe intrusions or a dozen other issues that allow groundwater to enter the structure. Unfortunately, once a leak occurs it will continue to worsen unless steps are taken to stop the infiltration of groundwater.At OBIC, we have earned a reputation for our industry-leading lining system that prevents infiltration from occurring. What is not so well known is that our lining system will not adhere to running water, so we first had to become experts in the science of stopping leaks. We went in search of grouts for wastewater rehabilitation that would allow us to stop even the toughest leaks. When we couldn’t find a product that met our expectations, our team took on the

OBIC Manhole Rehabilitation Process Ever wondered about what the manhole rehabilitation process is like for OBIC certified installers? We had a camera crew follow Advanced Lining, an OBIC installer located in Utah, as they worked on a municipal manhole rehab in Moscow, Idaho. The city of Moscow had 17 aging manholes with groundwater infiltration issues. Although experienced in rehabilitation projects like this, the installation crew was challenged with an unusually cold October. They were also faced with a limited timeframe, as the project was in a residential neighborhood. Site Safety Before any rehabilitation work can begin, site safety takes priority. The crew will set up traffic cones and signs to keep the public separated from the work area. Confined space and fall protection equipment is set up on-site and employees don their personal protective equipment. Manhole Casting Prep Now that

OBIC 5000 – Structural Manhole Rehabilitation Lining It is generally understood that the primary reasons for manhole rehabilitation are to stop inflow & infiltration, prevent hydrogen sulfide corrosion and restore structural integrity. At OBIC, we have talked extensively about inflow & infiltration as well as corrosion, but there seems to still be a lot of questions out there about how OBIC products help with structural issues. Two questions that we hear frequently are: What’s the definition of structural? What standard exists for manhole rehabilitation that defines structural? This blog post helps to answer those questions, but our team is always ready to discuss your unique manhole rehabilitation projects and questions. What standard exists for manhole rehabilitation that defines structural It is important to begin by explaining that there are no ASTM standards, structural or otherwise, for manhole rehabilitation methods. Not willing to settle, we did some

OBIC Preventative Maintenance = Peace of Mind When was the last time you inspected your system’s manholes? If your answer is an awkward silence, you are not alone. Many municipalities face challenges with limited budgets and resources, so manhole inspections are often put on the backburner until a noticeable problem occurs. Unfortunately, this means that you could have a manhole that is leaking groundwater right now. Although you may not yet see the impact on operations, you could have a leak that looks like this. The cost of manhole leaks add up Even the smallest leak has costs that begin to multiply over time. For example, a manhole that leaks two gallons of groundwater per minute will send over 1 million gallons per year to the wastewater treatment plant. According to one case study, this two-gallon leak

OBIC grout stops even the toughest leaks Manhole rehabilitation projects often involve brick and concrete structures that have cracks, missing or mortar deteriorated gaskets, pipe protrusions or other pathways allowing groundwater to enter. This is a common problem that occurs in manholes across the world, but one that causes a unique problem for OBIC installers. Although OBIC products are scientifically designed to stop sewer system inflow and infiltration issues, they will not adhere to running water. Specifically designed to stop leaks in water and wastewater structures Fortunately, OBIC offers a complete line of grout materials specifically designed for stopping leaks that occur in water and wastewater structures. The most common material used by OBIC installers for stopping leaks is polyurethane chemical grout. Polyurethane chemical grouts are usually injected under pressure as a liquid resin into or in the vicinity of the leak. Once the resin contacts water,

Manhole Rehabilitation: Brick Manholes The United States Environmental Protection Agency estimates that there are approximately 26 million manholes in the U.S. The majority of these structures are precast concrete manholes, cast in place concrete manholes and concrete block manholes, however, clay fired brick was a popular material used in the construction of manholes prior to the 1950s. A quick history lesson on precast concrete manholes In the post-World War II suburbia, young families in search of homes created a housing boom. Along with new homes, the rapid growth of communities began to make infrastructure a priority. Schools, community centers, churches, supermarkets, office buildings, industrial plants and shopping centers all required proper water and wastewater systems. In 1954, the Precast Concrete Institute was formed and precast manhole structures became the most cost-effective method for manhole construction. The high cost of labor and installation for brick manholes quickly

Causes of Corrosion The need for polymer sewer lining coating When OBIC was founded, it was with the mission of providing a long-lasting, cost-effective barrier of protection for water and wastewater structures. Polymer coatings and lining systems have proven time and time again that they offer the best combination of price and performance for addressing sewer system inflow and infiltration issues. Our website and blog posts are filled with data and information to support this. If you are wondering why polymer sewer lining coatings are necessary in the first place, you have come to the right blog post. The following paragraphs give an overview of what causes sewer inflow and infiltration issues and why polymer coatings are needed in the first place. Most common issues that make sewer lining repairs necessary The two most common problems affecting sanitary sewer structures are groundwater infiltration and deterioration

Save Energy and Money Energy Efficiency in Water and Wastewater Facilities Twenty-four hours a day, seven days a week, water and wastewater treatment facilities are humming with the sound of pumps and motors working to provide the community with clean water. Wastewater plants and drinking water systems can account for up to one-third of a municipality’s total energy bill (EPA 2009). These facilities represent a significant portion of controllable energy usage and offer opportunities for cost-effective investments in energy-efficient technologies. Energy efficiency measures in water and wastewater facilities can deal with the installation of energy-efficient equipment and also the adoption of improved processes. Pumping requires much of the energy used for treating and delivering drinking water and for transporting wastewater to and through the treatment plant. Installing a new, more efficient pumping system and adding new controls and sensors that improve automation can produce energy savings by

Polymer Misconceptions The Facts About Polymers and Wastewater Structure Rehabilitation At OBIC, we don’t hesitate to share the benefits of polymer lining systems for wastewater structure rehabilitation. As a matter of fact, you might say that we have made it our mission.

Wastewater Rehab Challenges Aging sewer infrastructure is a problem facing the entire country. Systems put in place decades ago are beginning to deteriorate and become inefficient. For a long time, this was a major problem for cash strapped municipalities that did not have the budget for a total reconstruction of their damaged systems. Today, there are effective alternatives to total reconstruction that will rehabilitate damaged wastewater systems and extend the life of the structure by 50 years or longer. Advanced polyurea coatings are cost-effective and “designed to create highly elastic waterproof coating and lining systems that are resistant to chemicals and abrasions,” according to an article written by WaterWorld. The article goes on to say that “they are ideal linings for immersed surfaces and will resist hydrogen sulfide.” With the advancement in polyurea coating options to rehabilitate wastewater systems, it is easier than ever to maintain and

Advanced polyurea coatings provide solution to aging wastewater infrastructure As much of our nation’s wastewater and sewer infrastructure continues to age, the demand for a high quality, affordable solution to infiltration and corrosion issues is on the rise.  Historically, wastewater structure rehabilitation has been a cumbersome and costly endeavor. Pump station rehabilitation, for example, once required digging up and replacing entire structures. Not only did this disrupt service for long periods of time, it would often result in road closures and safety concerns. Fortunately, advanced polyurea coatings provide a solution to this age-old problem. “Polyurea coatings and liners provide numerous benefits when it comes to the maintenance and repair of wastewater structures,” said Dustin Schlachter, CEO of OBIC. “The coatings are spray applied, which means they can be used on any configuration, and they are flexible enough to withstand the demands of the host structure. Perhaps the

OBIC products offer environmentally friendly solutions that meet the demands of the Severe Wastewater Analysis Test Conservation strategies create new challenges for wastewater systems Eco-friendly products and services with a focus on conserving our natural resources are an emerging trend across the world. The water and wastewater industries are no exception to this global trend. Conservations strategies that have been implemented to protect vital groundwater reservoir supplies have proven beneficial, however, they are not without their challenges. The old joke – “the solution to pollution is dilution” actually helps to explain what is happening. Reduced flow results in increased holding time in the collection system. This leads to increased microbial action, and therefore enhances corrosive activity. High-performance protective coatings rise to the challenge As a cost-effective solution to water and wastewater rehabilitation, high-performance, spray applied coating systems were developed. A long-held belief was that these coatings, although affordable,
