The most plausible explanation is that it refers to the . Early editions of the book were published by Dhanpat Rai and Sons around this time. A library record shows a 1982 publication, suggesting that editions from this era are still found in some library catalogs. Searches for "80" are likely attempts to find a scanned PDF of these older, out-of-print editions , which may have entered the public domain or be more readily available on file-sharing sites.
This section focuses on the collection, treatment, and safe disposal of wastewater. Key topics include:

Understanding the Request for This Textbook "Water Supply and Sanitary Engineering" by G.S. Birdie is a foundational textbook widely utilized in civil and environmental engineering programs across South Asia. The book offers comprehensive coverage of municipal water treatment, distribution systems, sewage disposal, and environmental sanitation.
Analyzing physical, chemical, and biological parameters, including Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).
Allowing quick reference during laboratory sessions or field projects without needing the physical book.
Raw water must be treated to meet potable standards. The standard treatment train includes:
