Nuts & Bolts of the operation

At the heart of Martelle Water Treatment’s operation  are our quality, NSF certified, products, and our unique, state of the art small bulk delivery system. All of the chemicals we offer are NSF certified as required by the AWWA, EPA, and Wisconsin DNR. These products are tested and tracked from the manufacturer to the customer’s door. Our facility is regularly audited by NSF for best practice of procedures & storage, while the chemicals are regularly sampled and tested for meeting or exceeding NSF standards. Our small bulk delivery system was set up to reduce and is some cases, eliminate the handling of chemicals by water operators. Our trucks are equipped with plenty of hose to access even the most remote locations while eliminating the need to move heavy drums and carboys that can cause accidents & injuries. We comply with all DOT regulations and requirements for transporting chemicals & hazardous materials.
