Preload LLC products

Preload tanks are proven to provide effective solutions for wastewater treatment including aerobic and anaerobic digesters, primary and secondary clarifiers, and sludge storage. Our wastewater treatment tanks are designed to incorporate the necessary structural components for the treatment process.

Water reuse continues to be an important step in the treatment process, particularly in geographic regions where water is scarce and rainfall is inconsistent to meet the demands of industries and residential customers. Reuse water is stored after the treatment process and is made available to businesses , to homeowners, to the agriculture industry for irrigation water, and to other industries for process and cooling water. Recycling water on site or nearby reduces the energy needed to move water longer distances or to pump water from deep within an aquifer. In addition, tailoring water quality to a specific water use, such as golf course irrigation, reduces the energy needed to treat potable water. Preload tanks have proven to provide effective solutions for water reuse tanks.

Combined sewer overflows (CSO’s) and sanitary sewer overflows (SSO’s) occur during major storm events due to a wastewater system’s design or infiltration into piping. Sewage system overflows can create serious health hazards and can endanger habitats, leading to closure of streams and recreation waterways. Preload tanks are the cost-effective solution to collect sewage system overflow and store the water until it can be reused or treated. Since Preload tanks can be built covered or open top, above and below grade, they can accommodate myriad CSO/SSO/EQ storage configuration needs faced by today’s engineers and municipalities. Preload engineers have a broad range of experience in the successful design of CSO/SSO storage tanks and equalization basins, and can easily incorporate the required conical floors, odor control systems, wash-down systems, and mixing equipment for these storage applications.

Preload leads in design and construction of LNG Prestressed Concrete Tanks. Preload was the first company to introduce the design and construction of prestressed concrete tanks for the storage of liquid natural gas (LNG), in which the stored cryogenic product comes in direct contact with the concrete wall. Our engineers have spearheaded the formation of ACI Committee 376, “Design and Construction of Prestressed Concrete Tanks for the Containment of Refrigerated Liquefied Gases (RLG).” Preload tanks are also proven to be ideal for storage of other liquids at cryogenic temperatures such as ammonia, butane, propane, ethane, ethylene and propylene.
