Are you looking to save more money on your water bill? If you’re the type who hates to flush clean water down the toilet, then perhaps this information on how to build a water recycling system will intrigue you. Water recycling systems can save as much as 15 gallons of water per person every day. The water recycled from the shower and bathroom sink will save you an additional 25 gallons of water every day. This adds up to 50,000 gallons of water in savings every year.

How to Build a Water Recycling System: The Basic Principle

To begin, you should first understand how water exits through the plug hole in the bathroom sink and the bathroom shower. It collects from two soil pipes fixed near the side of the home. After it has entered the soil pipes, the water gets pumped up into a loft where a storage tank keeps it in good condition and ready to flush it down the toilet.

When you’re first picking up on how to build a water recycling system, you should first gather the parts needed:

  • 1 x 40 mm waste pipe
  • 2 x 110 mm soil waste pipes
  • 3 x 40 mm fitting for 110 mm soil pip
  • 1 pump
  • 2 x end caps screw on type
  • Storage tank with a lid
  • Foam filter
  • 2 ball cocks
  • 1 one-way valve
  • 2 magnets
  • 2 relays
  • 2 reed proximity switches
  • Some cable

1. Assemble the Water Collection Pipes

First, you should lay out two of the soil pipes, and you will drill a hole in both of them at one of the ends. This lets you put in the 40 mm fittings, and afterwards, you can combine these two pipes. You will glue the two 40 mm fittings also. When you apply the glue, you must check the adhesive on it, and you should also make sure it remains sealed because the pressure in the bottom of the pipe will build up to excessive amounts. After you have applied the glue, drill a second 40 mm hole closer to the upper part. Through the hole, you can add what’s known as the overflow pipe.

Finally, glue the screw onto the inspection end cap toward the end part of the tubes. As the adhesive dries, you can design the main off-switch mechanism.

2. Design of the Off-Switch Mechanism

An interesting part of the design, the off-switch mechanism could be reduced to a magnet with a pivot arm and the bull cock. In addition, you have a reed switch, and that will go on the outside. The process of what happens occurs as the water rises. For example, the ball cock will pull the arm to move the magnet into position to go against the tube.

3. Prepare Your Storage Tank

The storage tank employs a 15 mm pipe, which stretches from the pump over to the toilet to supply it with water. Here you need the overflow pipe and the bull cock and the magnet attached to it. As the water rises, the reed switch cuts the power of the pump to save you on your water bill. If you’ve never learned how to build a water recycling system, this is one of the ways to do it.

4. Fit Pipes onto Your Wall

After you have dried the tubes, you will fit the blank end cap onto them. One of the tubes will have the bull cock and magnet arm fit onto it. You will bolt the two tubes into place near the wall, and you will use the 40 mm tube to fit between the two. Once you have done this, you fit the overflow and the waste pipe from your bathtub near the top. Also, make sure you installed the foam filter closer to the end of your pipe. You hold this in place using chicken wire bent over the pipe.

5. Work the Plumbing System

You will attach a 15 mm copper pipe to bottom of your collection tubes. Next, you run the 15 mm pipe through the house and to the upper region of the tank. You will have to make a control box. To do this, you will have two relays. The relay wire goes to your collection tube, and it’s normally open. Meanwhile, the relay for the tank will usually be wired shut.

6. Connect the Control Circuit Wiring Pump

You will run some of the bell wire from the control box over to your reed switches. After that, you wire the pump to the control box. Next, you begin the testing of the system. For example, check to make sure the water exits through the plug hole and fills the collection tube for recycling the water. You will want to look for leaks, and if you discover empty water, add more adhesive to your piping system to eliminate the leaks. After the adhesive dries, test it again for leaks, and if it still leaks, apply the adhesive again until you have taken care of it.

Summing Up

In the final stages of how to build a water recycling system, you will fine tune it to make it better. Over a period of six months, you might encounter a problem where the switches fail. If you have this happen, make a simple transistor circuit. The problem relates to how the current is too strong, so you use the transistor circuit to lower the strength of the current. This is how to build a water recycling system. It can be a fun project to engineer the subtle intricacies of it, and at the same time, you will save money on water usage.
