Louisiana · Washington Parish
Our Louisiana DEQ shortlist has 2 firms filed in Washington Parish on the approved sewage sludge transporter list. Retrieved September 5, 2026.
The parish shown here is the physical-address parish on the Louisiana Department of Environmental Quality approved sewage sludge transporter list. It identifies where the registered firm is filed, not a promised service area. LDEQ titles the list Approved; this snapshot was retrieved September 5, 2026 and does not establish that a registration is still current the day you book. Confirm that the company serves your property and re-check its registration on the official LDEQ list before booking.
LDEQ publishes a company name, contact, physical address, parish, and registration number for these firms. It does not publish a phone on this list, so we do not invent one.
LDEQ listed 309 approved transporter rows (307 registration numbers) when this snapshot was retrieved. The same registration covers domestic septage, portable-toilet waste, municipal sewage sludge, and sludge mixed with grease. To keep this homeowner directory focused, we publish the subset whose company name explicitly says septic or septage. Restroom-, WWTP-, vacuum-, waste-, and pump-only names stay out unless the same company name clearly identifies septic work.
