Distribution Boxes & Customized Polylok© Donuts in Duncan

A distribution box is an important component of your sewage disposal system. When the wastewater is discharged from the septic tank, it enters the distribution box. The distribution box helps to evenly divide and channel the wastewater to the drainage system. It is critical that it is levelled uniformly to prevent unequal distribution. One of the easiest ways to check for the levelness of your distribution box is to add water to it. 

To fulfill your septic tank needs, Galcon Precast Ltd in Duncan offers three different concrete distribution boxes. You can also bring your septic tank to grade with our Polylok© donuts or risers.

Our distribution boxes come with either concrete lids or a Polylok© riser and lid. Distribution boxes, although small, are essential to your septic tank's sewage disposal processes.

Great Experience


i had a great experience in dealing with  Dans Precast. i had to lift and move a septic tank to a lower level and the whole process went very smooth. The driver (cliff i believe) was very professional,  thoughtful and friendly and very easy to deal with .

i had to coordinate the lift after i had pumped the tank. Ernie (in the office) was able to coordinate a lift time that worked out for all of us.

i will use Dans Septic in the future for sure. do not hesitate to call, they have a newer crane truck that can lift all kinds of things...just call them and talk to them about your needs....Great job and thank you again, jim
