Recently enacted environmental legislation makes the containment of wastewater and animal waste a requirement rather than an option.  COMANCO provides cost-effective solutions to prevent seepage of runoff that contains nitrates, ammonia, phosphorus and bacteria that can harm and foul waterways.  However, these contaminants – if properly contained and managed – can be applied to land nutrients, leading to a significant reduction in fertilizer costs.

Using the highest quality geosynthetic liner material, COMANCO builds lined and covered storage basins that allow for the retention of liquid and semi-solid waste for subsequent controlled disposal or land application.  Additionally, to prevent contaminants from entering into the surrounding environment, geosynthetic covered containment systems are also effective in reducing or eliminating odors. Traditional compacted soil and clay liners are simply not enough.  In addition to constructing new containment ponds and canal liners, COMANCO can also reline your existing ponds.

Climate change and population growth have increased the demand for water while America’s farmers are being asked to produce more with

Since 1989, COMANCO has been working with the agricultural industry, across the country, to find and implement cost-effective solutions to help mitigate their legal and environmental risk.  Our highly trained engineers, quality control technicians, and field installers ensure the job is done the right way, ‘The COMANCO Way.’  We test every weld and seam and follow strict production protocols because your business and our reputation depend on it.  At COMANCO, we are committed to doing our part through the use of advanced materials and systems to conserve water and prevent contamination of the groundwater and adjacent streams.


COMANCO is the leader in building geomembrane-lined Aquaculture ponds and lagoons for:

  • Fish hatcheries
  • Fish farming
  • Recreational fishing facilities
  • Shrimp and oyster farming
  • Seaweed and algae production

Geosynthetic liners installed by COMANCO offer the most economical and cost-effective solutions for modern aquaculture.  Once installed, the geomembrane provides superior leak protection and is virtually maintenance free.

Decorative Ponds

Decorative ponds provide an added dimension to any architectural design. COMANCO installs decorative ponds for:

  • Golf Courses
  • Reflecting Ponds for Monuments
  • Commercial and Municipal Fountains
  • Artificial Landscape Features
  • Amusement Parks and Zoos
  • Private Homes
  • Public Gardens
  • Resorts

A decorative pond or lagoon lined with a geomembrane is vastly superior to the compacted clay-lined ponds of the past.  Compacted clay liners are expensive to install and tend to crack and leak over time.

COMANCO installs geosynthetic liners quickly and economically while using minimal equipment.  The flexibility of the geomembrane allows the liner to conform to any size and shape and can accommodate the most creative design requirements.  The edges of the liner can be blended into the surrounding landscape creating an undetectable transition.

Floating Covers

For over 34 years COMANCO has been constructing and installing floating covers as a cost-effective alternative to fixed cover systems for:

  • Liquid and semi-solid storage
  • Potable water storage
  • Odor control
  • Biogas capture
  • Chemical containment
  • Evaporation control
  • Reduce airborne containments and algae growth
  • Heat loss prevention

COMANCO offers a complete Floating Cover solution including:

  • Cable tensioned cover for potable and process water
  • Defined sump covers for clean and process water
  • Pressure dome covers for biogas capture and containment

COMANCO has extensive experience installing all types of geomembrane materials such as HDPE, reinforced polypropylene and XR-5, dependent upon the material to be contained.

COMANCO supports the use of Geosynthetics for Sustainable Development.


A solid waste landfill is a complex, engineered system with many components working together to assure that environmental standards for containment are achieved. If you are a company or municipality responsible for handling millions of tons of solid waste every year, you understand the importance of keeping up with federal regulations and meeting EPA requirements.

COMANCO works with some of the largest solid waste companies and municipalities in the country, providing landfill construction services that include:

  • Geosynthetic liner installation including a complex “double-composite” system where multiple layers of membrane, clay components, and drainage medium are combined to provide ultimate prevention
  • Earthwork and site preparation
  • Landfill gas control and recovery piping systems

Using COMANCO’s proprietary software and GPS satellite technology, we can provide a geographically accurate rendering that includes the physical detail, elevation, and panel by the number of the site, leaving no room for error.

COMANCO meets or exceeds all current safety and quality control standards with a team of trained engineers, quality technicians, experienced field installers, and heavy equipment operators ready to start a project anywhere in the continental U.S. Canada and Puerto Rico.  Be assured the job will be done the right way, ‘The COMANCO Way,’ because your business and our reputation depend on it.

Precious Metals Mining

Precious metals’ mining has advanced for all precious metals, with the help of methods driven by escalating market prices and new technology.

For over 34 years, COMANCO has been helping mining producers, by providing efficient recovery solutions that allow the capture of every ounce of precious metals from wastewater effluent, while continuing to meet the EPA guidelines, to help protect the surrounding area from contamination.

COMANCO is one of the largest installers of geomembrane liners used for the storage and containment of wastewater generated in the mining process.  Our meticulous attention to detail and quality has earned us a reputation as the leading authority on the deployment of geosynthetic materials in the country.

In addition to constructing new containment facilities, COMANCO conducts renovation and relining of existing storage areas.  COMANCO meets or exceeds all EPA requirements, with an aggressive quality control program, which tests every weld, seam, and panel to ensure total integrity, because your business and our reputation depend on it.

Phosphate Mining

COMANCO started serving the Florida Phosphate Mining industry in 1989. Today, we are the first choice for phosphate producers who depend on our experience and knowledge of this industry.  COMANCO has gained over 34 years of experience in building and maintaining storage facilities for phosphate gypsum, a processing by-product.

Many of our phosphate mining customers have been using COMANCO exclusively for years where we have established a continued presence, continuously moving from site to site.  Over the years, the number of phosphate producers has dwindled, in part, because of increased regulation and the risk that comes with it.

COMANCO understands these risks and the importance of doing the job right, the first time. Our stringent quality control program ensures that every weld, every seam, and every panel will meet or exceed the required specifications and perform to those standards for years to come.

COMANCO understands the bottom line and the need to contain costs, as well as, waste. Employing a staff of well-trained engineers, quality control technicians, field managers, and installers, we can reduce or increase crew size as the project demands. This helps to keep your costs low while providing the ultimate in safety, quality, and service. That’s ‘The COMANO Way’ because your business and our reputation depend on it.
