Absorption Bed Septic System Website Copyright of VME 2017, all Rights Reserved. A transport from an existing tank is connected to the new tank. A pump doses effluent to the absorption bed drain field. Chambers are set side by side which make these systems well suited for compact sites.  Clean outs are installed at each lateral end. The system is neatly back filled and graded to prepare the yard for new sod (the dog already likes it!). “Val - Thank you so much for taking care of our septic so quickly and efficiently.  Throughout the project you went above and beyond and we are so grateful!”  Scott & Teri Crowe - Bozeman, Mt Customer Comment From This Project:
