Classification of low impact development rainwater control and utilization facilities
1 Scope
This standard specifies the classification principles, code structure and coding method, facility classification codes and
name.
This standard applies to the classification and coding of low-impact development rainwater control and utilization facilities.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Low impact development
Emphasizing that urban development should reduce the impact on the environment, its core is based on the concept of source control and reducing the impact load, building and self-reliance
However, suitable drainage projects, rational use of space and corresponding measures to control stormwater runoff, reduce urban runoff pollution.
Note. Rewrite GB 50014-2006 (2016 edition), definition 2.1.8B.
2.2
Stormwater management using stormwater management and harvest
The general term for reducing the total amount and peak value of runoff in urban areas and reducing runoff pollution and collecting rainwater for reuse.
Note 1.Rewrite GB 50400-2016, definition 2.1.1.
Note 2.Including rainwater stagnation, collection and reuse, storage and storage, sewage purification and transmission, etc.
3 Classification principles
3.1 The principle of balance
The main functions of low-impact development of rainwater control and utilization facilities are mainly based on the control objectives.
3.2 The principle of scalability
Low-impact development rainwater control and utilization facilities not included in this standard may be coded according to the coding method.
4 Code structure and coding method
4.1 Code structure
The line classification method is used to divide the low-impact development rainwater control and utilization facilities into three levels. large, medium and small, as shown in Figure 1.
