Revolutionize Your Waste Disposal: How To Make A Septic Tank With 55 Gallon Drums!

Building a septic tank can be a daunting task, but with the right materials and instructions, it can be a manageable DIY project. This comprehensive guide will provide you with a step-by-step process on how to make a septic tank using 55-gallon drums, ensuring a reliable and efficient wastewater disposal system for your home.

Materials Required

• 4 x 55-gallon plastic drums
• 3-inch PVC pipe
• 3-inch PVC T-fitting
• 3-inch PVC elbow
• 3-inch PVC end cap
• Silicone sealant
• Gravel
• Sand
• Measuring tape
• Level
• Shovel
• Drill
• Jigsaw

Step 1: Prepare the Drums

• Cut the top off of one drum using a jigsaw. This drum will serve as the inlet tank.
• Cut a 3-inch hole in the center of the bottom of the inlet tank.

Step 2: Connect the Drums

• Connect the inlet tank to the second drum (primary tank) using a 3-inch PVC pipe. Insert the pipe into the hole in the inlet tank and seal it with silicone sealant.
• Connect the primary tank to the third drum (secondary tank) using another 3-inch PVC pipe.
• Connect the secondary tank to the fourth drum (outlet tank) using a 3-inch PVC pipe.

Step 3: Create the Baffle

• Cut a 3-inch PVC T-fitting in half.
• Insert one half of the T-fitting into the inlet tank, facing the primary tank.
• Seal the T-fitting to the inlet tank with silicone sealant.

Step 4: Add the Elbow and End Cap

• Insert a 3-inch PVC elbow into the T-fitting, facing down.
• Insert a 3-inch PVC end cap onto the end of the elbow.

Step 5: Dig the Trench

• Dig a trench that is 6 feet long, 3 feet wide, and 4 feet deep.
• The trench should be level and have a slight slope towards the outlet tank.

Step 6: Place the Drums in the Trench

• Place the drums in the trench in the following order: inlet tank, primary tank, secondary tank, outlet tank.
• Level the drums using a level.

Step 7: Fill the Trench

• Fill the trench around the drums with gravel, leaving about 6 inches of space at the top.
• Fill the remaining space with sand.

Troubleshooting: Common Problems and Solutions

• Slow drainage: Check for blockages in the pipes or baffles.
• Bad odors: Add bacteria to the septic tank or check for leaks.
• Overflowing: The septic tank may be too small or in need of pumping.

Questions We Hear a Lot

Q: What is the purpose of the baffle?

A: The baffle prevents solids from entering the secondary tank, allowing only liquids to flow through.

Q: How often should I pump the septic tank?

A: The frequency depends on the size of the tank and usage. Generally, it should be pumped every 3-5 years.

Q: Can I use metal drums instead of plastic drums?

A: No, metal drums can rust and contaminate the soil.
