Burt's System

In this 45,000-gallon system, rainwater flow into the Eliminator, then into a 5000-gallon tank pump tank that's activated by an internal float switch. The water is pumped through a sand filter and then into two 20,000-gallon tanks. A float switch in the collection tank tells the pump tank if it can accept any more water. When the collection tanks are full, the pump tank fills to overflow. (Note the low point drain on the white pipe.)

Natural Gardener System

This is a 12,500-gallon fiberglass tank outfitted with a 200-gallon Eliminator at John Dromgoole's Natural Gardener, a destination nursery just outside Austin, Texas. Note the two-inch low point drain on the trunk line, the hose bib on the tank, and the barely visible hose bib on the Eliminator. The site indicator tube drapes over inlet to the tank. See how the vacuum breaker on the Eliminator is higher than the collection tank's inlet? For more on the Natural Gardener, go to www.naturalgardeneraustin.com.

Gravity-Fed System

Rainwater flows from the roofs, through the Deleafer, into the downpipe and then into the Eliminator or the first flush tank. When the water in the Eliminator is at the same level as the collection tank inlet, the rainwater then flows into the collection tank. Note the low point drain, a crucial component to elimate standing water in your trunkline, which can be a problem during mosquito season or a hard freeze.

Overhead System

If your tanks are located right next to your collection surface, you can run your trunkline overhead and you'll have no standing water in your trunkline that might freeze or breed mosquitos if not drained.

Eliminator and Pioneer Tank

Here a fiberglass Eliminator is paired with a metal Pioneer Tank, which, because it's assembled in place, is a great choice for those hard-to-get-to sites down a cliff or in a forest.
