Many hauled or trucked liquid wastes are concentrated and could negatively impact the treatment plant or cause pass through if discharged directly into MRWPCA's headwords intake. Therefore the Agency has a liquid waste receiving facility where loads are accepted under strict requirements (pH, toxicity, etc.). Discharged liquid wastes are slowly bled by batches into the influent waste stream so as not to cause treatment works upset.
MRWPCA accepts liquid waste from permitted haulers. Accepted sources include: chemical toilets; septage; restaurant grease; biocell (oily waste); certain special wastes (storm drain pump outs; corn starch dye; wine waste; vegetable waste: artichoke and grape pulp); and salt brine solutions. Submission of a completed load manifest is required prior to discharge of any load.
