GB/T 48060-2026Stormwater pretreatment facilities for sponge city construction (English PDF)

GB/T 48060-2026 is the English-translated version of 海绵城市建设用雨水预处理设施.

Sponge city construction aims to manage urban rainfall by absorbing, storing and treating it, and this document deals with one element of that approach: facilities that pretreat stormwater before it enters further storage, infiltration or treatment. The title places it in the equipment and facility category used for sponge city projects.

Municipal designers, engineering consultants, construction contractors and suppliers of stormwater equipment are the main audience, as are the authorities and owners who need to specify or accept such facilities. Manufacturers can also use it to describe their products in terms that project teams will recognise. It is a recommended national standard, so it is voluntary unless adopted in a contract, design brief or local rule. It was issued on 28 August 2026 and takes effect on 1 March 2027 under the Ministry of Housing and Urban-Rural Development. It is an original Chinese document and does not adopt an international standard. Pretreatment protects downstream infiltration and storage components from debris and sediment.
