Water 💧
This page provides insights into the data from the Water sensor. The charts are based on data representing the water consumption(litres) and min/max/avg temperature per hour for each resource.
Overview
The Water Usage dashboard tracks total water consumption, water cost, and hot-water temperature across the estate. It also surfaces a Sankey distribution view across floors and resources, making it an essential tool for both finance reporting and HTM 04-01 compliance.
Use this dashboard to:
Monitor consumption against expected usage and detect leaks
Convert water consumption to cost (£) for finance reporting
Demonstrate hot-water temperature compliance (HTM 04-01)
Identify the heaviest-use fixtures and target retrofits
Detect out-of-hours flow that signals stuck flushes or leaks
Dashboard Structure
The dashboard is organised into four tabs:
Monitoring
Data
Map
Floor Heatmap
A metric switcher toggles every chart between Water Consumption and Water Cost.
Tab 1 — Monitoring
Total Water Consumption
KPI card.
Total consumption (litres or m³) for the period.
Total Water Cost
KPI card.
Total cost (£) for the period, calculated from consumption, tariff, and standing charge.
Water Temperature Trend
KPI card with thermal indicator.
Average hot-water temperature for the period, with HTM 04-01 status:
🟢 PASS — Maximum hot-water temperature ≥ 55°C
🔴 FAIL — Maximum hot-water temperature < 55°C
Water stored or distributed below 55°C presents a Legionella risk.
Water Consumption Trend
Line chart with Hourly / Daily / Weekly granularity tabs.
Water consumption over time, with optional cost overlay.
Use it to: spot leaks (a flat baseline rising overnight is a leak signature) and benchmark consumption against expected demand.
Water by Resource
Horizontal bar chart with Top N / Bottom N controls.
Resources or zones ranked by total water consumption or cost.
Use it to: identify the heaviest-use fixtures — typically toilets, showers, and kitchens — for targeted retrofit programmes.
Water by Weekday
Bar chart.
Water consumption or cost by day of the week.
Use it to: detect out-of-hours flow that signals leaks or stuck flushes.
Water Across Floors and Resources
Sankey flow diagram.
A hierarchical flow from Floor → Resource Type → Individual Resource, with ribbon width proportional to consumption.
Use it to: present the building's water-flow story in a single image, suitable for executive and sustainability reporting.
Tab 2 — Data
Water Data Table
Sortable data grid.
Water consumption readings (m³) and water temperature per resource with timestamps. Supports CSV export.
Tab 3 — Map
Water Map View
Interactive geographic map.
Buildings plotted on a world map, colour-coded by total consumption.
Use it to: compare water performance across sites and prioritise efficiency programmes.
Tab 4 — Floor Heatmap
Water Floor Heatmap
Colour-coded overlay on an interactive 2D floor plan.
Water density rendered directly onto the building's floor plan.
Use it to: find consumption hotspots — typically wet rooms, kitchens, and plant areas.
Filters & Controls
Building, Floor, Resource, Resource Type
Date range with presets and custom ranges
Granularity tabs on trend chart
Top N / Bottom N selectors on resource ranking
Metric switcher: Consumption / Cost
Tips
Hot-water temperature dips frequently correlate with boiler-cycle timing — share findings with mechanical and electrical engineering teams.
A sudden water-volume spike with no occupancy spike often signals a stuck flush or leak.
Use the HTM 04-01 PASS / FAIL indicator as evidence in monthly compliance reporting.
