Wessex Water Event Duration Monitoring 2025

The overall objective of this use case is to pro-actively publish data that is regularly requested via Environmental Information Regulation Requests (EIRRs). By supplying historic data about the activity of event duration monitors situated at storm overflows, we believe that we can reduce requests for localised storm overflow performance data. The data will detail a lower level of granularity and higher update frequency than the Environment Agency (EA) Annual returns, but a more accurate picture of storm overflow operations than is currently available in the National Storm Overflow Hub (NSOH). The Coast and Rivers Watch web map and National Storm Overflow Hub feed facilitates the near-real time reporting of storm overflow start and stop data. The built-in quality assurance function automatically removes flatlines and data spikes and is calibrated on a site-by-site basis to achieve the best level of accuracy. Further in-depth assurance continues after publishing on the web map and collated into an annual file of all data. This is the complete file for 2025. Schema: Field Name DESCRIPTION DATA TYPE EXAMPLE DATA SiteId * Unique Identity of the Storm Overflow String ABC123 SiteName The name given to the Storm Overflow String Paris Road SO ReceivingWatercourse The name of the watercourse into which a discharge is directed String River Trent PermitReference The reference for the permit used String abc123 OutfallLatitude * Latitude of the outfall Float 52.21691 OutfallLongitude * Longitude of the outfall Float 0.14449 IsBathingWater An indication of whether the outfall meets a designated bathing water Boolean True BathingWaterName The name of the bathing water into which the outfall discharges String Spring Lake EventId The unique identifier assigned to this event String abc123 EventStart * Date and Time that the monitor indicated a discharge had started DateTime YYYY-MM-DDTHH:mm:ss EventEnd * Date and Time that the monitor indicated a discharge had ended DateTime YYYY-MM-DDTHH:mm:ss Duration The length of time between the event’s start and stop time Duration P3Y6M4DT12H30M5S EventVerified An indication of whether this event is verified at the time of it being published Boolean False *Mandatory **Requires a standard value本用例的总体目标为主动发布环境信息规制申请（Environmental Information Regulation Requests, EIRRs）定期索要的数据。通过提供设于暴雨溢流设施（Storm Overflow）的活动时长监测数据，我们认为可降低针对本地化暴雨溢流性能数据的申请需求。本数据集的粒度低于英国环境署（Environment Agency, EA）年度报送数据，更新频率更高，但相较于国家暴雨溢流枢纽（National Storm Overflow Hub, NSOH）现有公开数据，本数据集能更精准地呈现暴雨溢流的运行状况。海岸与河流监测（Coast and Rivers Watch）网页地图及国家暴雨溢流枢纽数据馈送功能，可实现暴雨溢流启停数据的近实时上报。内置质量保障功能可自动剔除平线数据与异常尖峰，并针对每个站点逐一校准，以实现最高精度的质量控制。在网页地图发布数据后，还将开展进一步的深度质量保障工作，并将所有数据汇总为年度数据文件。本文件为2025年完整数据集。 数据结构（Schema）： | 字段名 | 字段描述 | 数据类型 | 示例数据 | --- | --- | --- | --- | | SiteId* | 暴雨溢流设施唯一标识 | 字符串 | ABC123 | SiteName | 暴雨溢流设施的命名 | 字符串 | Paris Road SO | ReceivingWatercourse | 排污所指向的受纳水道名称 | 字符串 | River Trent | PermitReference | 所用排污许可的编号 | 字符串 | abc123 | OutfallLatitude* | 排污口纬度 | 浮点数 | 52.21691 | OutfallLongitude* | 排污口经度 | 浮点数 | 0.14449 | IsBathingWater | 排污口是否属于指定沐浴水域的标识 | 布尔值 | True | BathingWaterName | 排污口排污所进入的沐浴水域名称 | 字符串 | Spring Lake | EventId | 分配给该事件的唯一标识符 | 字符串 | abc123 | EventStart* | 监测设备显示排污开始的日期与时间 | 日期时间型 | YYYY-MM-DDTHH:mm:ss | EventEnd* | 监测设备显示排污结束的日期与时间 | 日期时间型 | YYYY-MM-DDTHH:mm:ss | Duration | 事件起止时间间隔 | 时长型 | P3Y6M4DT12H30M5S | EventVerified | 数据发布时该事件是否经过验证 | 布尔值 | False * 为必填字段，** 需采用标准取值。
