# Water

### 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](/uma-knowledgebase/data-and-reporting/insights/water-legionella-detection-guide.md)

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:

1. **Monitoring**
2. **Data**
3. **Map**
4. **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) per resource with timestamps. Supports CSV, JSON, and PDF 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.
