About HTI Tank Wash

HTI Tank Wash has been operating in Oakland, California for over 25 years. We originally built the Wash Rack for cleaning our own tank trucks. Harkrader Trucking, Inc., our trucking company, hauled food grade products and light chemical commodities in the San Francisco Bay Area and surrounding counties.

New regulations in the industry put a higher demand on facilities with Food Grade capacity. We expanded the Wash Rack to four wash bays inside the building and two outdoors. Business from competitors increased to a point that most of our attention was providing service for the many tank trucking companies trafficking through the Oakland/San Francisco area. We decided to sell the trucking business and direct all of our attention to the wash rack. We continue to provide quality tank cleaning service to the industry.

Our facility is equipped with a Clayton Steam Generator, a 4,000 gallon stainless steel hot water tank, a 3,000 gallon detergent tank, a 3,000 gallon stainless steel cold water tank, and a 3,000 gallon stainless steel chemical tank. High volume, high pressure, steam, water, and detergent are delivered to the different bays through 30HP high volume pumps and Gamajet 360 Roto-jets.

We have developed a Treatment System with the capability of eliminating restricted elements and that produces an effluent that is compatible with the environmental boundaries, set by the United States EPA, the local Publicly Owned Treatment Works (POTW) which is East Bay Municipal Utility District (EBMUD).
