In 1985, the Tangipahoa Parish Police Jury (now Tangipahoa Parish Council) voted to create a parish-wide sewer district, in accordance with Louisiana Revised Statute 33:3811, thus the Sewer District No. 1 of Tangipahoa Parish was born.
The Sewer District No. 1 of Tangipahoa Parish is governed by a board of commissioners consisting of five members. The board is appointed by the parish council and paid according to the number of meetings attended. The District encompasses all non-incorporated areas, with a few exclusions for some previously franchised areas of Tangipahoa Parish.
As of December 31, 2013, Sewerage District No. 1 of Tangipahoa Parish provides service to a total of 3,246 customers.
