What is the best rainwater diverter for rainwater harvesting?


Rainwater harvesting

Rainwater diverter play a very important role in rainwater harvesting. Rainwater harvesting refers to the simple technology or process of conserving rainwater. So, It usually involves a rainwater diverter for collecting, storing, and transporting rainwater from roofs, parks, roads, and open spaces for later use.

Rainwater is prized for its purity, softness, and resiliency. It has a pH of almost neutral and is entirely free from any disinfection products, salts, minerals, or other contaminants.

Why do we need to harvest rainwater?

The rainwater harvesting method is one of the most efficient methods used and implemented to help ensure water conservation. The scarcity of high-quality water is an issue of great anxiety. Rainwater, however, that is clean and of high quality can be utilized to water irrigation, washing, cooking, cleaning, bathing, and in addition, other needs of livestock.

Essential components of rainwater harvesting system

  • Catchment surface
  • Gutters and downspouts
  • Roof washers, first-flush diverters, and leaf screens
  • Cisterns are storage tanks that can be used to store water.
  • Delivery system
  • Treatment and purification

Best rainwater diverter

As their name suggests, the First Flush diverter flushes out the water from a storm’s first flood before reaching the storage tank. This water could be most affected by particulates, bird droppings, and other materials on the roof. Removing these impurities from rainwater before they reach your storage is crucial.

Why is the First flush diverter a critical component of the rainwater harvesting system?

A First Flush (rainwater diverter), which is a device that flushes water from your system after you have screened your gutters, is the following line to protect your system. This diverter allows you to flush out any debris or dirt accumulated on your roof or gutters during rainy periods. These devices don’t typically use power, so they are low-cost and low-tech ways to improve water quality significantly.

By using the first flush diverter, we can achieve the following benefits:

  • They improve the quality of rainwater.
  • Decrease tank maintenance
  • Prolong the life of components of the harvesting system

What is the working principle of first-flush rainwater diverters?

Rainwater diverters are usually installed to make your rainwater more safe and fresh. Rainwater diversion systems typically consist of several meters long vertical PVC pipes. They are generally installed along the piping to the top of your tank.

Rainwater will flow into your gutter, down your piping, and eventually into your vertically-installed PVC pipe. This pipe is filled with rainwater. The line contains a special ball valve inside that rises with the water. The ball valve seals the tube once it is complete. This will prevent rainwater from escaping. The rainwater flows down over the ball into your rainwater tank.

It is essential to let go of rainwater that has been collected in your water diversion system. It will be impossible to refill again in the event of future downpours. A slow-release valve is usually located at the bottom end of vertical PVC pipes. You can also install a drip irrigation system in your garden to avoid rainwater waste.

Where is a first-flush diverter installed?

A rainwater diverter could be put near the tank or close to the downspouts. When it drizzles, and the water drips down on the roof and gutters, it flows out of pipes to the diverter. The diverter is filled up with the first raindrop from the top. The cleaner water is pumped through the tank when the diverter has filled.

A bend in the diverter pipe or floating ball valves prevents diverted water from flowing back into the line and the tank. A small drain hole at the bottom of the tube lets the diverted water flow in a steady stream, ensuring that the pipe is empty and waiting for the subsequent rain. A threaded cap is put on the other end of the line to permit the frequent cleaning of fallen leaves and various other particles.

Advantages of using a first flush diverter

  • First flush diverters form an essential component of any rain harvesting system.
  • These devices are designed to divert and take the most polluted and sediment-laden water that flows into your pipes from the roof after the first millimeters of rain.
  • After the contaminated water has been taken out, the diverters seal to allow better water to flow over and into your tank.
  • By keeping these contaminants and pollutants away from the tanks, First flush diverters improve the quality of your rainwater and safety, increasing the lifespan of your pump and appliances and lower maintenance needs for your tank.      
  • The benefits have been proven by scientists and by top manufacturers of water pumps.
