A Faster Dewatering Solution for Pipeline Construction and Repair

Are you looking for a quick and easy way to dewater your worksite for pipeline construction and repair? It’s likely you have spent some time researching and are looking for the fastest dewatering solution available. Whether you are installing a pipeline underneath a body of water or building near the water, the success of your project depends on keeping your worksite dry.

Conventional Dewatering Methods

You may be relying on some of these more conventional methods that have been around for millennia:

  • Earthen dams
  • Sandbags
  • Sheet pile
  • Pumping

These methods have conventionally been relied on heavily to complete pipeline construction or repair projects requiring dewatering. While they have been successful for the most part, these methods do leave room for concern. Conventional methods have been known to be messy, with a negative impact on the environment. Many of them are often time-consuming to deploy, and cost-prohibitive – affecting your bottom line.

Quick and Efficient Dewatering for Pipeline Construction and Repair

Aqua Barrier® is different than any other dewatering solution on the market. It provides the fastest and most efficient dewatering solution for pipeline construction and repair. Here are just some of the reasons why:

  • Can Withstand High and Uneven Pressure
  • Eliminates the Need for Pumping or Sandbagging
  • Aqua Barrier® can be Installed in Less than 3 Hours
  • Comes in Various Sizes to Fit Any Size Project
  • Can be used on Slick Surfaces Using Steel Piping
  • Resistant to Cold Temperatures (See how the Frost Buster kept water inside of the barrier from freezing on this Minnesota pipeline repair)
  • And it’s Eco-Friendly!

Perhaps most importantly to project engineers and construction managers is the cost savings. This new dewatering solution has saved hundreds of thousands of dollars on big construction projects. Savings come in both time and money which is crucial in the field of construction; a construction project using sheet piling costs over $41,000 versus less than $19,000 using the Aqua Barrier®. And when you’re finished, simply drain the barriers for quick removal.

Due to its versatility, many contractors choose to rent rather than purchase Aqua-Barriers® as different projects require different sizes.

Aqua Barrier® water-inflated cofferdams save potentially hundreds of thousands of dollars in project costs and lots of time in man-hours. It offers the fastest install and removal of any dewatering method on the market.

5 Key Benefits of a Water Filled Cofferdam

Whether you are laying pipes in a river or lake bed, performing maintenance on an underwater structure, or building a bridge, dewatering the worksite is a must. Cofferdams are widely used for this purpose and come in many shapes and forms. Water filled cofferdams have become a popular choice in many industries due to the many benefits associated with this type of solution.

Why Choose a Water Filled Cofferdam?

If you have never used a water filled cofferdam before for your projects, you may be wondering how it is different and how it compares to using sandbags or other types of cofferdams.

Here are 5 Key Benefits of using a Water Filled Cofferdam for your Next Project:

ONE: Water filled cofferdams are easy to fill and quick to install.

This type of cofferdam solution goes up very quickly and easily because the water does all the work.

TWO: Fill material is available in abundance on site

Water is readily available on site so you never have to worry about carrying enough fill material with you to set it up.

THREE: Molds perfectly to physical environment

Water is pliable and flexible. When you fill the cofferdam, it forms to the river bed, lake bed, or other environment with no resistance.

FOUR: Forms airtight seal to prevent water escape

With sandbags and other materials, you run the risk of water escaping through the cracks. With a water-filled cofferdam, this risk is eliminated due to the nature of the seal that is formed when it is installed.

FIVE: Eco-friendly, no environmental footprint

Water filled cofferdams are reusable and have no environmental impact. Not only does this reduce product waste, but also saves money as they do not have to be replaced often.

At Hydrological Solutions, we are experts on water filled cofferdams. Our Aqua-Barriers® are built to help provide our customers the peace of mind they deserve when working in sensitive conditions.

Dewatering: Keep Your Pipeline Construction Worksite Dry

Dewatering to keep a Pipeline Construction site dryPipeline construction projects involve a great deal of time, money and resources. Dedicated engineers, general contractors, project managers and construction crews work diligently to ensure the process is smooth and cost-effective.

However, construction sites located under water or in water logged areas present an interesting challenge. You have to keep the worksite dry in order to complete the project and ensure the safety of your team.

How do you Keep an Underwater Worksite dry?

A worksite that runs under a lake or other area of water will require dewatering to prepare the site before work can begin. Dewatering removes ground or surface water and has traditionally been done by pumping or using sandbags.

However, the pumping process can be costly and sandbags have proven to have their own set of issues, including a negative impact on the environment.  

A Better Alternative for Dewatering

Fortunately, there is an environmentally-safe option available for keeping your pipeline construction site dry. The Aqua-barrier cofferdam has saved project managers hundreds of thousands of dollars in pumping costs with no environmental footprint!

How does the Aqua-barrier Cofferdam work?

The Aqua-barrier cofferdam is designed to withstand pressure and friction, even when exposed to uneven water pressure. Where sandbags are time-consuming to fill and lay, and pumping must be done repeatedly to keep the site dry, the cofferdam is easily set up in a matter of 2-3 hours, and remains steady throughout the course of the project.

An Aqua-barrier cofferdam is also an effective dewatering tool for underwater pipeline inspections. Eliminate the need for costly pumping and filthy sandbags and give the cofferdam a try.

Aqua Barrier for Various Dewatering Projects

Hydrological Solutions provides industrial products to meet and exceed the demands of a variety of dewatering projects. But what does dewatering actually mean? And how is it used in an industrial setting?

De-codeing Dewatering

Dewatering is a term used to remove water from solid material or soil.  The methods of dewatering vary based on need and specifications for each project.  In order to complete a successful dewatering project, the area needs to have a perimeter around it to secure the area inside to prevent (additional) water to come inside.

Dewatering projects come in all shapes and sizes. Hydrological Solutions’ Aqua Barrier Cofferdam provides a multi-purpose solution to:

Flood Control: How to Read a Flood Plane Map

Flood Control: How to Read a Flood Plane Map

How to Read a Flood Plane Map

A Flood Plane Map contains valuable information that is pertinent to industries such as oil and gas, construction, Pipeline construction, as well as industrial construction. Flood Maps may incorporate these jurisdictions: Counties, Townships, Towns, as well as Cities. FEMA allocates each a six-digit Community Identifier (CID).

There are two common types, Flat Flood Maps and Z-Fold Flood Maps. The flat flood map includes one, sometimes more, 11”x17” pages, while the Z-Fold Flood Map is larger and folds up as a road map commonly would. Every flood map has the basic essentials, including the index map, panel, title box, legend and standard symbols that remain consistent from map to map. Regardless of what kind of map is being used, most will only cover one jurisdiction at a time.

Flood Map Overview.

The Index: acts as a guide to map sheets found on a Flood Map. As the geographic coverage of a Flood Map is often quite huge, FEMA splits the range into segments named panels.

The Panel: The Community might contain more than one individual maps. Each map is a panel.

The Title Block: Available on each Panel (or page), and the community name, date, the panel/page number.

Community Name: The title block portrays name of the mapped community, the county, and the state.

Community Number: the community identification number (CID), allocated to the mapped community.

The Body: Presents the map contents. Within the body, there are places of reference to pinpoint specific locations.

Corporate Limit or County Line: identifies the jurisdictional boundaries of the community’s regulatory authority over constructing or land development.

The Legend: Z-fold Flood Maps, the Legend features data for determining the risk zones and/or floodway on the Flood Map.

North Arrow: This arrow orients the Flood Map.

Panel Limit Line: outlines the section covered by each panel presented on the index.

Flood Maps possess flood hazard data on one or more communities. Before beginning any project or development, a company may need to identify Special Flood Hazard Areas (SFHA) or undeveloped coastal barriers, wherein flood insurance is not available. Businesses, organizations or individuals concerned with flood control will also find flood maps valuable.
