Water Towers: Purpose, Engineering, Functionality, and Infrastructure



Water towers are integral components of municipal water systems, serving to store and distribute potable water efficiently. Their design and operation are rooted in fundamental principles of physics and engineering, ensuring consistent water pressure and supply across various terrains and populations.

Fats, Oils, and Greases in Sewers: The Hidden Dangers and Prevention Strategies



Sewage backups and overflows are a growing urban problem, often caused by fats, oils, and greases (FOG) entering the sewer system. When FOG is poured down drains, it cools and sticks to sewer pipes, accumulating over time and leading to blockages. These blockages can cause sewage to reverse flow, spilling into streets, storm drains, and even rivers—posing serious public health and environmental risks. This article explores how FOG enters sewers, the formation of destructive “fatbergs,” and the best strategies for prevention and mitigation.


What is Hydraulic Gradient Line

The hydraulic gradient line (HGL) is a fundamental concept in fluid mechanics, particularly in the analysis of fluid flow in pipelines and open channels. It represents the energy state of the fluid within a system, providing critical insights into pressure variations and flow behavior. Understanding the hydraulic gradient line is essential for engineers and hydrologists to ensure efficient and effective drainage system designs. This article will explore the definition, significance, and applications of the hydraulic gradient line, along with related concepts such as the energy grade line (EGL) and practical implications in hydraulic engineering.



Manhole Grouting: Essential Techniques for Sewer Rehabilitation

Manhole frames and covers must be replaced in areas where they are damaged, misaligned with street grade, or allow storm water to infiltrate the sewer system. The replacement process involves excavating a small pit around the manhole, which typically takes a couple of days to complete, including excavation, installation, backfilling, and resurfacing.


The Importance of Underground Reservoirs: Structure, Types, and Applications

Underground reservoirs are remarkable geological formations that serve a vital role in storing natural resources, particularly natural gas and water. These reservoirs have unique properties that allow them to effectively contain and manage various fluids. This article explores the structure, types, and applications of underground reservoirs, highlighting their significance in energy storage, water management, and environmental sustainability.

Double Suction Impeller: Elevating Centrifugal Pump Efficiency and Performance

The double suction impeller is a crucial component in centrifugal pump design, particularly for applications requiring high flow rates and efficiency. This type of impeller, which utilizes a back-to-back configuration, allows for a balanced hydraulic load and enhanced performance in various engineering applications. In this article, we will explore the characteristics, advantages, and applications of double suction impellers compared to single suction designs. By understanding these differences, users can make informed decisions when selecting pumps for their specific needs.



Deuterium-Depleted Water: Understanding Its Chemistry, Production, and Health Implications

Deuterium-depleted water (DDW) is a unique form of water that contains a significantly lower concentration of deuterium, an isotope of hydrogen, than found in natural water at sea level. Often referred to as light water or protium water, DDW is distinct from the conventional use of “light water,” which typically denotes regular water in nuclear contexts.

Addressing the Lead Hazard: The Importance of Galvanized Service Line Replacement


Detecting lead-lined galvanized steel pipes is crucial for utilities aiming to comply with new regulations. Water agencies can utilize various detection methods to identify lead lines. Lead-lined pipes have been part of U.S. drinking water systems since the late 1800s, originally promoted by Wakefield Galvanized of Massachusetts as a cost-effective, corrosion-resistant option. Over time, many water departments adopted these pipes, especially in the Northeast and Midwest.

Innovative Solutions for PFAS Removal: The Role of ROTEC Reverse Osmosis Technology

As concerns over per- and polyfluoroalkyl substances (PFAS) contamination escalate, effective solutions are essential for ensuring clean drinking water. One promising technology is ROTEC reverse osmosis, which offers enhanced removal efficiency for these persistent pollutants. This article explores the challenges posed by PFAS in drinking water, the limitations of traditional treatment methods, and how ROTEC’s innovative reverse osmosis technology can provide a sustainable solution.


Pipe Corrosion Protection Using Polywrap: A Detailed Technical Overview
