deal­ing with waste wa­ter

Homebuilding & Renovating - - PROJECT ADVICE -

In this case we mean both grey wa­ter and black wa­ter (from toi­lets), in other words, drainage. A sep­tic tank is the tra­di­tional an­swer but these need emp­ty­ing at least an­nu­ally. The al­ter­na­tive is a sewage treat­ment plant or biodi­gester, like the Klargester BioDisc treat­ment sys­tem, which breaks down the ma­te­rial which then out­falls to a drainage field. Sludge build up will need clear­ing out over time by a li­censed waste re­moval con­trac­tor.

Cap­i­tal cost of this op­tion is higher than a sep­tic tank but the run­ning cost is less than £20 per year (typ­i­cally to power the biodi­gester) com­pared to £200 to empty a sep­tic tank. There are also mod­els which work with­out elec­tric­ity.
