Use of STP Treated Water in Concrete: Assessing Strength Properties and Promoting Sustainable Water Practices

Abstract

Quality management in the construction industry today must address not only structural durability but also environmental sustainability. This study examines the dual objectives of improving construction quality and reducing water pollution by implementing treated wastewater reuse practices. It emphasizes strategies such as proper waste disposal, sustainable agricultural methods, industrial regulation and wastewater treatment to control water pollution. A key focus is the experimental use of STP (Sewage Treatment Plant) treated and untreated wash water in concrete production. Compressive strength tests performed on concrete cubes mixed with 70% STP treated water and 30% potable water yielded favorable results, indicating the potential of treated wastewater in maintaining quality standards in construction. Supported by previous research findings, this study highlights how integrating sustainable water reuse into quality management frameworks can enhance construction performance, reduce environmental impact and contribute to broader ecological conservation goals.
