Sewage Tanks — Product Registration

Sewage tanks include the following types of tanks: Septic tanks, Trash tanks, Holding tanks, Pump tanks, Surge storage tanks, Recirculation tanks and other processing tanks. The "List of Registered SSTS Sewage Tanks," and other related information, is provided on this web page.

Tank registration

In March 2011, the MPCA completed minor changes to the sewage tank design requirements contained in Chapter 7080. These changes affect sewage tank manufacturers. For this reason, as part of the rule amendments, MPCA extended the final tank implementation date for all tank manufacturers to April 4, 2012. Another extension, to November 15, 2012, has been offered to those manufacturers who are in the process of getting their tanks registered. The list of "in-process" manufacturers is included in the At-A-Glance listing below.

Until December 31, 2012, tank manufacturers will be allowed to continue to sell sewage tanks that meet the newly amended design standards or the design standards contained in the 2005 or 2008 rules. Tanks from manufacturers who are fully registered or are in the process of becoming registered by April 4, 2012, (as shown by their inclusion on the "in process" list) can be used through calendar year 2012.

Sewage tank manufacturers can submit their 'Application for Sewage Tank Listing' (see below under 'Forms for Sewage Tanks'), along with required information, to be placed on the 'List of Registered SSTS Sewage Tanks' if the requirements for tank registration are met.
