The Wisconsin Precast Concrete Association is a statewide, nonprofit trade association comprised of precast concrete product manufacturers from throughout Wisconsin and industry suppliers. WPCA members are dedicated to manufacturing durable, watertight concrete septic tanks, as well as a wide variety of other products manufactured to fit your needs, including agricultural products, precast concrete buildings, box culverts, traffic barriers and much more.

Concrete septic tanks

Structurally sound and watertight when manufactured to industry quality standards, precast concrete onsite wastewater systems outperform and outlast systems comprised of other materials. Quality precast tanks are designed to withstand loads that other materials cannot bear, and a routinely serviced tank will provide many decades of trouble-free service. Whether for residential projects or commercial construction, precast concrete is the material of choice for onsite wastewater treatment systems.

Why Precast Concrete?

  • Strength - Concrete increases in strength over time as opposed to other materials that may deteriorate.
  • Durability - The service life of precast concrete has been shown to be in excess of fifty years.
  • Buoyancy - The specific gravity enables precast concrete to resist buoyancy making it ideal for below-grade construction.
  • Fire Resistance - Precast concrete is noncombustible.
  • Quality Control - Precast concrete is produced in a controlled environment that enhances quality and uniformity.
  • UV Sensitivity - Precast concrete does not degrade from exposure to sunlight.
  • Environmentally Friendly - Precast concrete is a Green Building product made of environmentally safe and natural materials.
  • Weather Resistance - Precast concrete is well-suited to all types of weather conditions.
  • Watertightness - Precast concrete and high quality sealants offer your solution for watertightness requirements.
  • Ease of Installation - Precast concrete installs rapidly and with simple connections, low susceptibility to damage during backfill.
  • Availability - Precast concrete is available through thousands of manufacturers throughout North America.
  • Low Maintenance - Precast concrete requires little or no maintenance. Cleaning of septic tanks, for example, does not require special equipment for buoyancy or qualified ground conditions.
