There are mainly two ways to install your rainwater tank and the most common would be the Dry System. Both systems are displayed below.


The Dry and Wet Systems

The Dry System


The Dry System

The Dry System is the most common system and involves overhead pipes connected to your gutters feeding into your water tank.  This system is called the dry water tank system as the feed pipes run dry after the rain has stopped.

With this water system the main consideration is to ensure the tank height is low enough to allow fall into the tank and that the overhead pipe is well supported.





The Wet SystemThe Wet System

The Wet System used for years in the country, this system enables the water tanks to be positioned away from the water collection source and uses the principal that water will always be level. As the line fills and builds up, the water will then spill into the tank.

When the rain stops, water will remain in the pipework and therefore it is called the wet system. When installing this kind of water system we ensure mosquito protection and pre-filtering of the water before it enters the charged system to keep pipes clear.


The Location


Where you put your water tank is important, so when choosing a location for your water tank you need to:


  • Think of the areas in your house and garden where most of the water will be used.

  • If the rainwater tank does not fit in your preferred location, consider placing elsewhere or select a different shape or size.

  • Review the existing locations of your downpipes.

  • Consider your neighbours, ensuring your water tank does not block their natural light, ventilation or outlook or detract from the street scape.

  • If you want to install a pump, make sure it is located in a place that will have low noise for your family or neighbours.

  • Consider access to the tank and your home for maintenance purposes.

  • Building regulations may also limit where you can locate a rainwater tank on your property in relation to the front, side and rear boundaries.

  • Be aware of the stress placed on retaining walls, caused by locating a rainwater tank above or near any retaining walls, both on your property and your neighbour's property.


You can install a rainwater tank yourself, taking into consideration the points mentioned above, but if you feel you need some sound advice before commencing, then contact Brookwater Tanks and talk to an experienced installer.
