Water-saving enterprise building materials industry

1 Scope

GB/T 44566-2024 sets the criteria by which a building materials enterprise is recognised as water saving. Cement, glass, ceramics and concrete plants use large volumes of water for cooling, dust suppression, slurry and washing, and they are concentrated in northern provinces where water is scarcest, which is why water use per unit of product is a regulated quantity there and not merely a cost. The standard sets the evaluation index system and the requirements under it, covering management indicators and technical indicators, with normative annexes giving the scoring method for the management indicators and the calculation method for the technical indicators, so that the assessment produces a number rather than an opinion. It took effect on 1 January 2025.

This document specifies the index system and requirements for evaluating water-saving enterprises in the building materials industry. This document applies to cement, ready-mixed concrete, concrete admixtures, cement products, stone, building waterproof materials, flat glass, Evaluation of water-saving enterprises in the glass fiber, building sanitary ceramics, and insulation materials industries.
