Urban Waste Water Treatment Directive (UWWTD) Sensitive Areas - Nitrates

This dataset is a shapefile showing the extent of Urban Wastewater Treatment Directive (91/271/EEC) (UWWTD) sensitive areas (nitrate). The Urban Wastewater Treatment Directive (91/271/EEC) regulates the collection and treatment of waste water from homes and from industry. In the UK, the directive is implemented through the Urban Wastewater Treatment regulations 1994. Under these regulations, water bodies that are used as sources for drinking water and which have high nitrate concentrations (as defined by Council Directive 75/440/EEC of 16th June 1975) should be designated as sensitive areas by Defra. This dataset consists of rivers currently designated as UWWTD nitrate sensitive areas.

本数据集以形状文件的形式展示了《城市污水净化指令》（91/271/EEC）（UWWTD）敏感区域的范围（氮氧化物）。《城市污水净化指令》（91/271/EEC）规定了来自住宅和工业的废水的收集与处理。《英国城市污水净化条例1994》是该指令在英国的实施细则。根据这些条例，用作饮用水源且具有高浓度氮氧化物（根据1975年6月16日理事会指令75/440/EEC的定义）的水体应由环境、食品和乡村事务部（Defra）指定为敏感区域。本数据集包含目前被指定为UWWTD氮氧化物敏感区域的河流。
