Structurally sound and watertight, precast concrete on-site wastewater systems outperform and outlast systems comprised of other materials. Workman Precast septic tanks are designed to withstand loads that other materials cannot bear, and when routinely serviced, will provide many decades of trouble free service. Workman Precast standard sizes are available from 1000 to 2000 gallons in capacity. Special sized units are available upon request. We set the tanks in place and provide other items for septic system such as laterals, end caps, distribution and drop boxes, along with risers and riser lids.
