The monitoring module

Everything needed for the monitoring cycle. In one place.

Safewater dMRV helps project teams collect, review, analyse and package monitoring-period information. VVBs can access the supporting records and documentation needed for their review, with evidence linked back to source data.

01

Capture in the field

Use the Android field app for household surveys, water-quality tests, volumetric readings and geo-linked photo evidence—even where connectivity is limited.

02

Review and analyse

Review records, flag anomalies and work from approved data for survey, water-quality and volumetric analysis, emission-reduction calculations and SDG indicators.

03

Report and verify

Assemble the monitoring report and supporting documents, share evidence with VVBs, and track documentation and review through the verification workflow.

A connected workflow

From monitoring activity to verification

Keep each stage connected to the records and evidence behind it—rather than rebuilding the story at reporting time.

Step 01Collect

Field surveys, water tests, volumetric readings and photos.

Step 02Quality-check

Review records, flag anomalies and approve data for analysis.

Step 03Analyse

Explore performance, water quality, volumes, ERs and SDG indicators.

Step 04Report

Compile monitoring-period results and supporting documents.

Step 05VVB review

Give verifiers access to the report, source evidence and document package.

Web portal

The Desktop view — every project, period and record

Run projects through their lifecycle, review field data, see analysis as it is approved, and keep the audit trail that a verifier will ask for.

Project overview and lifecycle

Each project shows its lifecycle stage (planning → design certification → monitoring review → performance review → credit issuance), its monitoring periods MP1–MP5, and every borehole on the map.

  • Boreholes plotted with status, village and technology
  • Key Performance Indicators like water purity, Daily yield and Emission reduced
  • Per-project access list — only named users see a project

Bring in data your way

Collect field data however it already exists for your project — guided surveys on the Android app, records you already hold in CSV or Excel, or a direct connection to the instruments and systems already deployed in the field.

  • Android field app, online or offline
  • Bulk CSV / Excel upload for existing records
  • IoT and other survey-tool integrations, for projects that need them
Available

Field app

Guided household, water-quality and volumetric surveys on Android, online or offline.

Available

CSV / Excel upload

Bring in records you already hold, instead of re-entering them by hand.

Available

IoT device feed

Connect flowmeters and other field sensors directly to the platform.

In progress

Survey-app integration

Pull data in from other survey tools your team already uses.

Review and data quality

Every household, water-quality and volumetric record moves through approve, reject and flag before it reaches analysis. Anomaly rules catch incorrect entries and duplicates early, so what gets analysed is clean — and strict anomaly checking is itself evidence of data quality a VVB can rely on, supporting stronger credit quality.

  • Status counts and bulk approve / reject
  • Anomaly severity per record, with the reasons recorded against it
  • Duplicate and out-of-range entries flagged before they reach analysis
  • Improves data quality

Data Analysis

Survey analysis, water-quality analysis and volumetric analysis show village-level and borehole-level results, and can be exported as CSV.

  • Key survey metrics — safe-water access, premise type, distance and time to water — broken down the way the emission-reduction formula needs them
  • Water-quality pass rates by village
  • Borehole output, daily yield and projections over a chosen date range

Photo evidence with built-in watermarking

Photographs are filed by category (borehole sites, grievance booklets, hygiene campaigns, water-quality tests, flowmeter records, LSC meetings, rehabilitation work, training sessions). Every image is stamped with the project's ID and the upload date.

  • Size limit (1 MB by default), set per project by the admin
  • Captions on every photo; download a full period as one zip
  • Access controlled

Access control and audit

Project access is granted by name, and every upload, review, deletion and access change is written to a searchable audit trail.

  • Access list per project, managed by the project admin
  • Audit trail of every action, with user, time and project (IP address where recorded)
Field app · Android

Built for the field, not the desk

The Android app gives enumerators a guided survey on the phone. Entries are saved on the device and sent when the connection returns, so a dead signal at the village pump does not lose a household's answers.

Capture in the field

  • Works offline
  • Guided household survey with consent and conditional questions
  • All surveys GPS location tagged
  • Volumetric readings by jerry can count or meter reading

Photos from the phone

  • Take a photo with the camera, or pick one from the gallery
  • Photos are resized on the phone to fit the project's limit before upload
  • Watermark and date added automatically on the server
Impact reporting

From approved records to the carbon report

Emission-reduction and SDG calculations are built from the approved data in the period, and the monitoring report and VVB package are assembled from the same source, so every figure can be traced back to the record that produced it.

Instant Emission reductions (ER) calculation, no waiting, no spreadsheets

A config-driven calculation engine turns building counts, baseline data and a few project-specific variables into emission reductions — recalculated instantly at the click of a button, with every step of the formula visible as an interactive trace.

  • Emissions reduced (tCO₂e), households served, total volume and usage rate as headline KPI cards
  • One click recalculates every metric — no waiting, no spreadsheets
  • Baseline and building-count data uploaded as CSV; a few variable inputs adjusted per period
  • Calculation tree traces every result back to its constants, baseline data and monitored readings

SDG indicators

Each SDG indicator the project contributes to is calculated from approved monitoring data, with a one-click source trace showing exactly which records and formulas produced the number.

  • SDG 1, 3, 5, 6, 8, 13 and 15 tracked where the project touches them
  • Percentage, tCO₂e or tonnes shown depending on the indicator
  • "View source trace" opens the formula graph behind each figure

Monitoring report

The period's report is assembled from its sections — executive summary, borehole performance, water-quality results, emission reductions, SDG metrics and stakeholder engagement — and marked ready when each section is complete.

  • Each section shows generated / uploaded / draft status
  • Final report downloadable as a PDF

VVB documents

Replace the back-and-forth of email threads and shared drives with one document portal. The verifier's full deliverable set — 33 required documents plus the VVB feedback exchange — lives in one place, where eligible reports are auto-generated rather than assembled by hand, and each document is verified and tick-marked by the VVB so submission readiness is clear at a glance.

  • One shared portal instead of email threads and SharePoint folders
  • Eligible reports and documents auto-generated directly from monitoring data
  • Verified checkbox per document, so readiness for submission is visible at a glance
  • Ready / generated / uploaded / pending counts, version history, and the whole package as one download
Security and governance

Who can see and change what

Six roles, and a per-project allow-list on top. A viewer on one project cannot see another project's records, even if the role would normally allow it.
