Retaining walls are commonly used to manage land on slopes, stabilize soil, and create usable space on uneven terrain. Whether in residential landscaping projects or large scale commercial developments, retaining walls play a crucial role in improving the functionality and safety of sloped areas.

Stormwater management systems are precast concrete structures designed for the pretreatment, detention, retention, infiltration, and/or reuse of urban stormwater runoff. Engineers, contractors, and government agencies depend on our expertise in building the most advanced stormwater systems available for volume control, low impact development, and green infrastructure outcomes using best management practices.

Jensen Precast offers design-build solutions with hydrodynamic separators, detention and infiltration reservoirs, biofiltration systems, oil/water separators, sedimentation systems, diversion structures, drywells, and pump stations.

Choosing the right septic tank size is critical for efficient wastewater management in any home or commercial property. A properly sized septic tank ensures the system operates smoothly, handling the household’s waste without issues like backups or odors. The size of a septic tank depends on several factors, including the size of the household, water usage patterns, and local regulations.

Monitoring septic tank levels is critical to prevent the risks and costly damage. The most important factor to check is an overfull system, which can lead to severe property damage and environmental hazards. Knowing how to recognize the signs of a full septic tank can save homeowners significant time and money in repairs.

Whether in a domestic or commercial setting, dealing with septic tank issues can be costly and [...]

When you purchase a septic tank, you’re hoping your investment will provide peace of mind for decades to come. But is that perception the reality?

If you’re new to the concept of septic systems, you may be wondering how they work and the functions they perform. In this article, we’ll walk you through the various types of septic systems, and help you understand them in more detail.

The type of precast concrete products you choose across the design, bid, build continuum will ultimately impact the overall costs, deadlines, and compliance needs of your projects. Here’s what you should know before making a decision.

Jensen MetalTech follows standards set by the American Society for Testing and Materials (ASTM) in product designs. Our engineers share a history of collaboration with ASTM for introducing new standards and updating current ones. We periodically publish guidelines about our products in relation to these standards.

There are numerous variables to consider while choosing a cover or lid. Our step-by-step guide will enable you to make the proper choices for your project. Regardless of whether for new development or a retrofit, Jensen MetalTech can offer the ideal solution.

Many utility companies and public works agencies choose aluminum access hatches because of it’s lightweight characteristics. Jensen MetalTech manufactures the highest quality aluminum access covers and hatches to fit utility company specifications.

Many utility companies and public works agencies choose steel or galvanized steel access hatches because of it’s durability and corrosion resistance. Jensen MetalTech manufactures the highest quality steel and galvanized access covers and hatches.

Jensen MetalTech pull box lids and covers with the LockLid™ brand of locking lids add an extra level of security for utility lids and covers. The patent pending LockLid™ K-Series of secure utility enclosure lids are the most secure lids on the market today

TraxPlate is a slip resistant surface applied to both aluminum and steel. TraxPlate provides a highly wear resilient surface with ideal slip resistant characteristics. TraxPlate far exceeds conventional non-slip materials, such as diamond plate, for slip resistance in both wet and dry applications.

The StormVault Biofiltration System is a simple and highly versatile stormwater treatment solution. Through physical and chemical filtration, adsorption, and biological processes, StormVault Biofiltration efficiently removes total suspended solids, metals, nutrients, oil, and grease from stormwater runoff to meet water quality standards as a low impact development best management practice.

Built with durable precast concrete, the JDS hydrodynamic separator also captures total suspended solids (TSS), oil, grease, and other total petroleum hydrocarbon pollutants. Captured pollutants are retained without scouring, even under high flow bypass conditions. Capable of treating flows from 0.7 to 72 cubic feet per second, the JDS Hydrodynamic Separator is certified and approved by various agencies.

Coalescing Oil Separators offer improved performance over traditional interceptors and sedimentation tanks. Jensen Precast coalescing plate separators and media packs specifically target the removal of oil, grease, or total petroleum hydrocarbons (TPH) for stormwater or wastewater applications.

When selecting an electric motor for a pump station, it is important to choose one that can develop enough horsepower to drive the pump.

Many control options are available to system designers these days. We will discuss soft starts, variable-frequency drives, and multiple pump systems.

Jensen Engineered Systems works with UL listed control system integrators to ensure that the control and communications for each project is properly executed.

The purpose of a check valve is to allow a fluid to move through it in one direction, but prevent it from flowing in the reverse direction.

Now that we know our minimum storage volume as well as the size of our wet [...]

The job of the inlet is to convey the liquid from the inlet pipe to the impeller [...]

When pumps operate away from their BEP, the pumps will generate uneven pressure forces inside the volute casing causing a radial thrust load on the impeller. The radial thrust load has many detrimental effects on the life of the pump. The first and most obvious is a loading on the bearings.

The most important part of any pump selection is determining the operating envelop of the pump. This means we must determine at the very least the required flowrate and head that will be required of the pump.

Selection of the proper type of impeller for your application can have a significant bearing on the applications ultimate success.

We desire high efficiency but also need good reliability and a minimal amount of ongoing maintenance. All of these considerations come into play when selecting the right impeller style.

Once we have determined our hatch dimensions, we can then size the diameter of the wet [...]

The design criteria that needs to be identified first is the total system inflow rate, and the flow at which the pumps will discharge. As discussed in the pump design section, the discharge flow can be found at the intersection of the system curve and the pump performance curve.

The Impeller is the heart of the pump in a high flow pump station. It is the only part of the pump that adds energy to the liquid. Grossly simplifying the process, energy is added by accelerating the liquid from the smaller radius at the impeller inlet to larger radius at the impeller exit.

Left turns, right turns, and degrees of angle are determined from the down stream perspective, that is, if you were to imagine the pipeline as a river and you are in a boat going down stream, you would be imagining the proper position from which to determine whether a turn is to the right or to the left.
