Constructed in 1970, Mitchell’s previous wastewater treatment plant had seen several repairs and improvements throughout its years of operation. However, an assessment of the facility’s structural condition and treatment processes presented by HDR Inc., a national engineering, architectural, and construction firm, recommended a thorough revision of the facility. As a result, the City of Mitchell’s project engineer stipulated that the headwaters, septage receiving station, and the treatment tanks of the new plant – all concrete structures exposed to the effluent – needed to be upgraded to ensure impermeability and enhanced durability.
Added to the concrete mix during the batching process, PENETRON ADMIX SB permanently reduces concrete permeability, and increases chemical resistance to the chlorides, sulfates, nitrates, disinfectants, various corrosive compounds, and the chemicals added during the plant’s treatment processes. It also enables the self-healing of any existing or future hairline cracks; this enhances durability and extends the service life of the treated concrete components.
