Back to the Basics of Proper Pipe Installation

The notion of bolstering safety factors in pipe design to compensate for subpar installation practices is a complex issue with various considerations. The effectiveness of buried flexible metal and plastic pipe systems hinges on a synergy between pipe strength and the surrounding soil support. Design procedures already integrate safety factors, emphasizing the vital role of proper installation in ensuring performance. Relying solely on increased pipe wall strength in design won't mitigate poor installation practices.

The Critical Role of Pipe Jointing in Large-Diameter Sanitary Sewer Systems

Proper pipe jointing is a critical aspect of designing and installing sanitary sewer systems – especially in the sizeable diameters of 30” and larger. The large joints of these systems play a pivotal role in preventing issues related to infiltration and exfiltration, which can have detrimental effects on the overall functionality of the infrastructure. Inflow and infiltration (I&I) during rain events can lead to capacity issues at wastewater treatment plants, causing severe backups in the system and sanitary sewer overflows (SSOs).

Techniques for Maximizing Runoff Reduction with Biofiltration

The terms “high-rate biofiltration” and “runoff reduction” aren’t often used in the same sentence. The engineering community has a preconceived notion that a high-rate biofilter with an underdrain (like Filterra®) can’t provide runoff reduction benefits because the stormwater it treats moves through the practice too quickly. However, with the proper design considerations, we can maximize the capability of a high-rate biofilter to provide appreciable runoff reduction.

Fundamentals of Stormwater Filtration: A Guide for Civil Engineers

As stormwater quality regulations become increasingly stringent, civil engineers are turning to stormwater filtration Best Management Practices (BMPs) to meet the demand for higher pollutant removal efficiency. In this blog post, we will explore the fundamentals of stormwater filtration, focusing on pollutant removal mechanisms, sizing methods, filtration mediums, and the advantages of proprietary systems.
