IS 10446:1983 is the Indian Standard (BIS) for glossary of terms relating to water supply and sanitation. This standard provides a comprehensive glossary of terms used in the fields of water supply and sanitation. It serves as a foundational document to standardize terminology for engineers, technicians, and other professionals in public health engineering, ensuring clear communication in projects, reports, and specifications.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Asset Management | Term not defined. The concept is outside the scope of a 1983 technical glossary. | Systematic process of developing, operating, maintaining, upgrading, and disposing of assets cost-effectively. A core concept defined with significant detail. | ISO 24513:2019 |
| Wastewater vs Sewage | Primarily uses 'Sewage' to denote waste liquid from domestic and industrial sources. | Uses 'Wastewater' as the broad term, with 'domestic wastewater' (often synonymous with 'sewage') and 'industrial wastewater' as sub-categories. | EN 16323:2014 |
| Service Pipe | Defined as the pipe that conveys water from the distribution main to the consumer's premises. Focus is on its physical location. | Defined as 'Service connection pipe'. The definition is often linked to the 'point of delivery' and includes associated fittings, which is critical for assessing performance indicators like leakage. | ISO 24513:2019 |
| Sludge | A general definition as the semi-solid residue from purification of water or treatment of sewage. | Detailed definitions distinguishing types like 'primary sludge', 'activated sludge', 'digested sludge', and 'biosolids', reflecting advanced treatment processes and resource recovery. | EN 16323:2014 |
| Water Quality | Defined in general terms relating to the physical, chemical, and biological characteristics of water. | Defined in relation to specific parameters and their limit values. The standard itself provides an extensive vocabulary for hundreds of specific analytes and measurement concepts. | ISO 6107:2021 |
| Appurtenance | A general term for any device or fitting connected to a pipeline, such as a valve, hydrant, or meter. | The term is used, but modern standards often prefer more specific terms or group them under 'components' or 'fittings' within the context of network models and asset inventories. | ISO 24513:2019 |
