Concrete is the most widely used building material in the world, thanks in large part to its inherent strength, durability, availability and adaptability.

Strong

Concrete continues to gain strength over time even after reaching its design strength. Because of their design, precast concrete onsite wastewater tanks can be made to withstand traffic loads with ease and can be pumped empty after backfill without risking damage to the tank. Precast tanks are engineered with the strength to meet any challenge.  

Watertight

Whether midseam, top-seam or anywhere in between, precast concrete onsite wastewater tanks provide reliable watertight solutions. Precast tanks are tested and verified to be watertight. This ensures the tank’s performance is not compromised by infiltration, and that soil and groundwater are protected. Joint sealants and resilient pipe connectors complying with applicable ASTM standards are designed specifically for this application and will contribute to a watertight structure.

Resistant to buoyancy

Precast tanks provide peace of mind as they resist buoyant forces with ease, even in the highest water tables.

Durable

Precast tanks are engineered structures made with quality raw materials in precise proportions, in controlled manufacturing facilities. This combination of quality control and quality assurance enables precast concrete tanks to stand up to the most demanding conditions.

Customizable

The size, shape, configuration and penetrations of a precast concrete onsite wastewater tank is up to you. Whether you need a stock tank or a completely unique solution, precast concrete tanks can fit your exact needs.

Easy to install

Precast tanks are easy to install regardless of soil type, water table height or other on-site conditions. Concrete’s inherent strength also allows precast tanks to be installed at greater depths.

Always advancing

The concrete industry has stood the test of time. It’s been thriving for millennia and it’s always advancing. New technologies are pervasive throughout the industry — from materials to equipment to designs — to adapt and meet your needs.

National Precast Concrete Association is an international trade association representing the manufacturers of plant-produced concrete products and the suppliers to the industry. NPCA is dedicated to expanding the use of quality precast concrete.
