What every filter has in common
Understanding the Difference Between Drains and Filters
Every filter is designed to catch contaminants. Every filter has an end point. The difference is that other filters are designed to be changed.
Geotextiles, resin-covered aggregate, and porous concrete are not. It is like replacing your engine when your oil or air filter is contaminated.
|
| A filter performs by catching contaminants. That is what filtration does. This is true in your furnace, in your car, in your water line, and underneath your bunker sand. Unfortunately your bunker filter, unlike a furnace filter, was not designed to be changed. It was expected to be permanent. But it is not. |

What this table tells you
› Every generation of passive bunker drainage acknowledged the last system failed, then built the same failure mode into its replacement at greater cost.
› SandSave is the only bunker drainage system with no filter media in the flow path, and therefore no replacement cycle designed into it.

Proven in the field - every installation, same result
Our work in the field has proven what the engineering makes obvious: passive drainage improves the moment SandSave goes in the ground, before the unit is ever activated. Not at one site. At every site. A drain in the ground drains. Call us and we will tell you what every superintendent who has installed SandSave already knows.
