High Time for Watertight Solutions

When to Apply Mechanical Repair Seals, and How

TrelleborgLet’s face it: America has a water infrastructure problem. And it’s getting worse.

Coast to coast, network owners, engineers and contractors face a running battle to fix aging pipe systems. Towns big and small are fighting water loss, sinkholes, and other major challenges. Eliminating expensive I&I and harmful exfiltration are important to communities; the time for durable, money-saving water asset management solutions is now.

In this innovative webinar, experts from Trelleborg Pipe Seals – a world-leading supplier of new and rehabilitation sealing solutions – will be discussing how mechanical seals can reinforce pipe systems and enhance existing pipe repair methods.

Rob Brockway, Director of Product Development, will explore the advantages of ‘No Dig’ for your potable and non-potable water pipe applications, offering best practice examples of these solutions in action.

Top 10 Must Ask Questions When Choosing a Pump Solutions Partner

sunbeltWith our nation’s aging wastewater infrastructure, many municipalities are turning to sewer rehab and civil projects to stay compliant and avoid unpermitted discharges. Due to the nature of these projects, the sewer flow cannot simply be shut down without causing major environmental issues. Therefore, the most critical component of these projects has become the flow diversion, or temporary bypass, allowing for the uninterrupted sewer flow to be bypassed around the work environment.

With the scale of these upgrades increasing in complexity and level of difficulty, bypass pumping is becoming the key factor in determining the overall success or failure of these projects. Not only is there substantial environmental risk in a bypass failure, there is also considerable financial risk associated with unanticipated change orders. With so much dependent on a well-executed bypass, how much front-end work is required to select a qualified bypass contractor? This webinar will detail the top 10 must ask questions to help you choose the right bypass partner to minimize risk and add project value.

Advancements in Slurry Microtunneling for Long Distance and Curved Tunnels

AkkermanAkkerman Slurry Microtunneling systems are used to install 30-114-inch pipelines that require precise line and grade in virtually all ground conditions from wet and unstable soils up to high compressive strength rock.

This remote-controlled, continuously supported pipe jacking method is suitable for non-disruptive installations under existing utilities, highways, railroads, levees, waterways, environmentally sensitive wetland and wet retrieval pipeline installations.

Microtunneling equipment has been around since the 1970s, but within the last decade, technological advancements have expanded the equipment’s realm of capabilities for a broader range of ground conditions and longer distances. Improvements in the variety and quality of cutter head tooling, tunneling navigation systems for extended length and curved alignments, lubrication products and lubrication delivery systems have made it possible to go further at larger diameters.

This webinar will overview the slurry microtunneling method, newest equipment innovations, tunneling navigation systems, lubrication options and recent case studies.

Inspection and Rehabilitation Trends: Large Diameter Water and Wastewater Pipelines

structural technologiesThe reliability of large diameter water and wastewater pipelines in metropolitan areas across the US has become more critical than ever. Based upon high water treatment and delivery demands, comprehensive asset management programs for pipelines have evolved and become more prevalent among owners in the past decade.

This webinar provides detailed information regarding the key inspection and repair methods used for large diameter concrete and metallic pipelines, and current trends in how owners are approaching this aspect of managing pipeline assets. It also provides up to date information on material selection, design best practices, installation and quality control for a variety of structural in-service and trenchless repair systems including external post-tensioning, CFRP and hybrid systems.

Attendees learn valuable information about inspection and rehabilitation, and how these critical components of asset management programs help increase the reliability of water and wastewater systems.

NASTT’s Sealing a Collection System Webinar

NASTTUtilities seeking to reduce Inflow and Infiltration from their wastewater collection systems have learned the hard way that it is not enough just to rehabilitate manholes and publicly-owned sewer pipes: the entire system needs to be restored, especially failing sewer laterals. The webinar will focus on proper techniques and materials for the renewal of lateral services using CIPP technology, with a special emphasis on restoring the connection of the lateral to the mainline sewer in accordance with the industry standard, ASTM F2561.

Industry experts from the NASTT membership will be presenting this complimentary webinar:
Larry Kiest, Jr., LMK Technologies, LLC
Jeff Maier, C&L Water Solutions, Inc. (Moderator)

Best Value Engineered Design for a Sealed CIPP Collection System

LMKThere are several requirements for a successful rehabilitation project. First it is necessary to seal the entire collection system. Case study after case study has shown that repair/replacement of only main lines results in less than 50% of the infiltration removal. Manholes, and most importantly sewer laterals that connect businesses and homes to the main pipes, also need to be rehabilitated. Second, the collection system needs to be sealed and as watertight as possible. Third, the project must be sustainable, capable of performing over the long term, for the next 50-100 years.

Larry Kiest, President, Founder and Chief Technical Officer and Rick Gage, Vice President of Sales discusses: The Challenges • The Trenchless Process • The Ultimate Long-Term Solution

SIPP – Systemic Faults & Next Level Solutions to Survive Pressure Pipe Failure

SippTechThis webinar will identify and explore lining faults that are systemic to the SIPP (Sprayed in Place Pipe) industry. The presenters will demonstrate how these lining faults prohibit most all current SIPP lining materials from surviving host pipe failure in pressure pipe systems, as well as to why some of these faults reduce hydraulic capacity.

This webinar will then focus on next level engineered solutions for preventing these faults to provide a fully structural SIPP or Class IV lining system with significantly increased hydraulic capacity in any pipe diameter pressurized system.

Manhole Rehabilitation: Understanding Why Hybrid Epoxies are Replacing Calcium Aluminate

CaldlinerManhole protection and rehabilitation has traditionally included either cementitious liners (particularly calcium aluminate and pure fused calcium aluminate) or epoxies for severe conditions resulting from H2S. These options have forced owners to either spend more money on costly, complex, specialized epoxy systems to improve performance or settle for the sporadic performance of the less expensive cementitious liners.
