Find Precasters or Suppliers that provide products, equipment and services to make precast concrete.
Stormwater management products are structures designed for underground installation that have been specifically engineered for the treatment and removal of pollutants from stormwater runoff.
These precast concrete products include vaults, catch basins and manholes. Most stormwater management products are modular in design and are available in a number of configurations. The structures and all connections are constructed with watertight integrity so that the contents discharge only through the proper outlet and at a prescribed flow.
Sanitary and Stormwater Products Case Studies
Bring on the rain. Quick and efficient, precast concrete underground stormwater systems are sized to channel large discharges in case of heavy rain to nearby bodies of water. Precast concrete withstands not only the volumes of water flowing inside them, but extreme loading conditions on the outside as well. And in both cases, they must stand up to corrosive elements. Precast concrete steps up to these challenges.

Precast concrete manufacturers, working in conjunction with trade associations like the National Precast Concrete Association, have developed tools to simplify calculations that engineers typically use in designing stormwater systems. One of these is the Stormwater Detention/Retention Calculator. The tool simplifies calculations needed to specify stormwater structures for underground detention/retention systems.

Stormwater Pipe Technical Drawing Examples
When wastewater has to get to the treatment facility and gravity is working against you, precast concrete lift stations can do the heavy lifting.
Precast concrete lift stations are designed, fabricated and installed with the highest-quality materials and equipment. Pumps and monitoring equipment can be installed and tested prior to delivery for quick and easy on-site installations.

Precast concrete manholes are an integral component of any modern sewer system. A properly designed and installed precast concrete manhole system provides superior watertight performance compared with competing methods and materials. A typical precast concrete manhole can be installed 500 feet deep and more because lateral forces act equally around the periphery, which places the section in pure compression – the ideal state for concrete. Precast concrete manhole sections are produced in a controlled environment, thus exhibiting high quality and uniformity.

Concrete pipe is instrumental in protecting precious groundwater by conveying wastewater and stormwater through complex underground infrastructure systems. You may not see it working, but precast concrete pipe plays a major role in preserving groundwater quality and ensuring a sanitary environment. Precast pipe is available in a huge variety of shapes and sizes. The flexibility and modularity of precast pipe make it possible to meet the needs of any sanitary wastewater or stormwater project. With its long history of unparalleled strength and proven performance, precast concrete is the material of choice for piping projects.
