Rainwater diverter-5 types of diverters used in water harvesting

Rainwater diverter


Rainwater diverter is used to collect rainwater. They are connected to a downpipe from the roofline, guttering toward the ground. They divert rainwater into a storage tank rather directly into the ground drainage system.

Rainwater diverter collect water from large areas, such as roofs of houses or barns. The gutters along the top edges direct water to the barrel or storage container. While some systems can be as simple as barrel diverters placed under a rain gutter and water, others may have more complicated drains or pipes that move water into underground storage containers.

Rainwater collection systems are created for a relatively low cost. People might collect rainwater in areas where they have access to water from the municipality. This act could cut down on water bills or help with conservation. Some places might have restrictions regarding aesthetics that prohibit rainwater collection from outside the house.

Although rainwater is usually safe, it may contain contaminants from roofs, gutters, or containers. Additional filters or water treatment may be necessary if the rainwater diverters are used for drinking water collection. Homeowners must choose materials that will not contaminate the water.

Types of rainwater diverters used in water harvesting

Downpipe Rainwater Diverter


The downpipe diverter is a reservoir that holds contaminated water. The downpipe diverter is filled with dirty water when it rains. A small floating ball surrounds the diverter. As the pipe fills, the ball rises to seal the T-junction. This process allows the water to be diverted into the storage tank. The downpipe diverter is slow to release water so that it will empty after the rain stops.

Following are some benefits of downpipe water diverters

  • It keeps our tank free from debris, bird droppings, and spiders.
  • It improves water quality and protects pumps, internal appliances, and other equipment.
  • It’s easy to install; all you need is pipe and glue.
  • There are no mechanical parts.
  • Low maintenance

Post/Wall Rainwater Diverter


Mountable on a wall or post, these First Flush Water Diverters can be mounted to a stand, position, or wall. They have larger chambers than the standard 90mm/100mm downpipe diverters and are often used with larger roofs to divert more rainwater.

All downpipes must be connected to one feed pipe for the storage tanks to use a wall or post diverter. It makes sure that all impurities from your downpipes are captured in one diverter reservoir. To ensure that your diverter has enough capacity to hold all your contaminated water, you will need to size it appropriately.

In-Ground Rainwater Diverter

Although they look the same as downpipe diverters, commercial diverters can be used to divert water from larger pipes and other large areas. Due to the large buildings, most systems are ‘wet.’ Long runs of lines running underground lead to risers at the tanks. This diverter is used to divert water from sloping sites. This d will create a dry system that improves water quality.

Tipping Gutter Rainwater Diverter

Tipping gutter diverters can be used to separate contaminated water. The system works by having a small segment that pivots into the storage tank.

The first flush is the water that moves into the gutter. It is then sloping away to the storage tank, and the impure water is diverted away. The diverted water is then stored in a bucket fixed to a pulley. The bucket gets massive, and the pulley raises it. This act causes the gutter to tilt towards the tank and allows the rainwater to move inside.

The bucket’s slow-release value allows the dirty water from the bucket to channel when the rain stops. The pulley system adjusts the gutter to its original position after it is empty. It then slopes away from the storage tank and tilts the bucket back into place when it is complete.

Commercial Rain water Diverters


Although they look the same as downpipe rainwater diverter, commercial diverters can be used to divert water from larger pipes and other large areas.

A rainwater diverter offers many benefits as Rainwater is very soft as it has not been through the soil minerals. It is much more effective than soap and leaves clothes cleaner. Rainwater makes hair smooth and shiny. Rainwater is suitable for both indoor and outdoor plants. It is also free of chlorine and other impurities. However, it contains more nitrogen due to its interaction with atmospheric electricity. Rainwater can also flush away any minerals or salts from hard water.

Rainwater diverters increases water quality, protects pumps, and reduces tank maintenance. They prevent the first flush of water (which may contain contaminants from roofs) from entering the tank. A critical component of any Rain Harvesting system is the first flush diverters. These devices capture and divert the most polluted, sediment-laden water from your pipes after the first few millimeters of rain. Rainwater diverters keep rainwater moving more quickly through the gutter system and offer other benefits. They can prevent roof leaks. They can avoid sagging gutters, rotted fascia boards, and sagging soffit & fascia boards.
