When the Fol-Da-Tank® and Float-Dock® Strainer were first introduced in 1954, the products were seen as the start of rural water supply. Over the years Fol-Da-Tank has listened to the needs of firefighters to develop the products we sell today.

1982 - The first tank Connector system was developed and Fol-Da-Tank set the standards for this product.
1989 - Fol-Da-Tank developed a combined Floating Strainer and Low-Level Strainer. We also developed our own Supply Line Holders which have evolved into the products that are being used today.
1990 - Fol-Da-Tank was chosen by the oil and gas company Schlumberger water division to develop the first 1" square tube aluminum frame. Fol-Da-Tank also introduced the first Double-Folding frame tank.
