GCP manufactures high quality, dependable Aerobic and Conventional Septic Tanks. ​
Starting with high quality concrete - reinforced with both synthetic fiber and steel rebar.
Our tanks have thicker walls and beefier corners making them much stronger and more structurally sound
than most other precast tanks. Plus, every tank is cured a minimum of 14 days, reaching more than
85% of its final strength, before it ever leaves our facility.
GCP stocks a full inventory of pipe, fittings, chambers and replacement parts.
These can be delivered with your tank at no extra charge or picked up at our shop.​
Our Mission is to provide you with the highest quality Aerobic and Septic Tanks in the market.
And to get you what you need, when you need it.
