Dawaco GW
Dawaco GW (groundwater) has been considered THE reference for groundwater data management for over 30 years, and is naturally also used by Dawaco BV itself within its full-service services.
The management of both quantity and quality data, and the two-way synchronisation with the BRO, make Dawaco GW unique in the Hydrogeological software market.
Dawaco GW consists of several modules, most of which are standard functionality. A number of modules are optional.
Below is a brief overview of the main modules and functionality.
The actual functionality is many times more extensive.
The basis of Dawaco GW
The basis of the Dawaco database is the well. All properties of a well can be managed with Dawaco.
Well construction, filter arrangement, materials, drill descriptions, salt guard electrodes, maintenance, and so on.
Dawaco GW's data model is fully compatible with the BRO data model, so that well and pipe data, can be managed entirely according to the IMBRO standard and then delivered to the BRO. All BRO search lists are populated in accordance with the IMBRO standard and constrained to that standard, so that no non-BRO compatible data can be entered on BRO fields. Lists are incidentally renewed when the IMBRO standard is updated.
However, Dawaco GW's data model is much broader than the BRO data model, so data managers can also manage many other relevant and non-BRE mandatory data with the system. Think, for example, of OLGA codes, aquifers. Well groups are also additional units that are not BRO mandatory, but still have great added value for e.g. reporting and walking rounds.
In Dawaco GW, the well is central. From the basic data module, all basic data of a well are managed. In this module, wells can be added, deleted, modified (coordinates, filter and monitoring well length, ground level height), drilling records added, etc.
Pressure gauge administration
The pressure meter administration in Dawaco GW is a special part of the software that allows you to centrally register and manage all pressure meters ((telemetric) loggers/sensors). Not only the measurements, but also the logistics and status of each individual pressure gauge are thus made transparent.
What can you capture?
Unique identification of each pressure Serial number, type, manufacturer, measurement range, accuracy, calibration date, etc.- Location status You can see at a glance where each pressure gauge is located:
- In a specific monitoring well (with date of placement).
- Stored in the warehouse.
- At a supplier for maintenance or calibration.
- On the move or temporarily out of service.
- Registering movements
- If a pressure gauge is moved to another monitoring well, then:
- Register this easily with date and location.
- Is the corresponding measurement series automatically linked to the new location.
- Remains available full usage history per pressure gauge.
- History and traceability
- You automatically build a historical record of:
- Where and when each pressure gauge was used.
- How long it sat in which location.
- Maintenance intervals, defects or replacements.
So :
- Efficient management of pressure gauges, especially in larger monitoring networks.
- Fast error detection, for example if an error in a measurement sequence can be traced back to a specific sensor.
- Maintenance planning and calibration management support.
- Working BRO-compliant: by knowing which sensor was in which monitoring well when, you meet the requirements for metadating groundwater measurements.
Groundwater levels
The groundwater level management module is much broader than its title suggests. In this module, you manage all things related to measuring groundwater teeth.
- Data logger administration - Which loggers are active, in storage or with the manufacturer for maintenance? This module gives full insight!
- Import - You import data logger files with groundwater levels, KNMI atmospheric pressure data, control measurements, manual measurements etc. using this module.
- Walk rounds - Within the module, you define walk rounds for field staff which you synchronise from Dawaco GW very easily and quickly with Fieldform
- Validation - Air pressure data (if from your own air pressure measurement) and groundwater levels are also validated in this module.
Import data from well-known brands of stand-alone groundwater data loggers
Files from well-known brands of data loggers (Keller, Van Essen, In-Situ (Koenders)) can be easily imported into Dawaco GW.
During the import, files can be selected from a run, specific measurement point group (user-definable) or by location.
Fieldform integratie
New since 2025 in Dawaco GW!
FieldForm is an app for Android and iOS to take location-based measurements in the field.
FieldForm allows the user to synchronise walking rounds from Dawaco, then record hand measurements in the field. When the walk round is completed, the hand measurements are synchronised with Dawaco GW.
FieldForm can also show and create images of the measurement points. Useful for recognising measurement points, for example in summer with a lot of vegetation or in winter with snowfall.
Integration with Dawaco is seamless: one press of a button is all it takes for synchronisation, both from Dawaco to Fieldform and vice versa.
Automatic reading of telemetry data
A new addition in Dawaco since 2025.
A new addition in Dawaco since 2025. This module inserts data posted via telemetry on an FTP server vol-automatically into the Dawaco database.
Telemetric loggers of the well-known brands are supported (Keller, Munisense, Leiderdorp and Van Essen), or can be easily implemented. That's not all, as this module also delivers the data directly to the BRO as provisional (unvalidated) series so that legal requirements are met.
In addition, the data can also be published in the GIS viewer.
Validatie
At Dawaco BV, validation is all about checking and improving groundwater data before it is used for analysis or delivered to the BRO.
Groundwater composition studies (GAR) can also be thoroughly validated using Dawaco's validation module and delivered to the BRO in accordance with the IMBRO standard at the push of a button.
Possible errors and anomalous values are automatically detected via various checks and visually highlighted in clear tables.
Validation with ArtDiver
ArtDiver works seamlessly with Dawaco GW.
Dawaco GW offers optional seamless integration with ArtDiver.
The familiar ArtDiver working environment is thus maintained while the data remains in one (Dawaco) database (single-source-of-truth principle).
Submission to BRO
(Subsurface Basic Registration)
Dawaco's data model is fully compatible with the BRO data model,
allowing well data (GMW), Monitoring Network data (GMN), pipe data (GLD) and quality data (GAR) to be managed according to the IMBRO standard and seamlessly delivered to the BRO. All BRO search lists are pre-filled and restricted to the IMBRO standard, allowing only BRO-compatible data to be entered into the BRO fields. However, Dawaco offers more than just BRO support. Its extended data model also allows management of non-BRO mandatory data, such as OLGA codes and aquifers, giving users a more complete picture of their monitoring network.
Two-way synchronisation BRO
Dawaco GW has the unique feature that not only can data be delivered to the BRO, but can also download data from the BRO AND compare it with the data in Dawaco.
This allows anomalous data to be correctedin either Dawaco or in the BRO.
New Dawaco GW users experience this as a huge convenience and time saver. Existing data in the BRO, such as well and water level data, can be extracted from the BRO at the touch of a button.
So the full history remains intact when switching to Dawaco GW.
Salters
Salt guards are measuring instruments used to measure salinity in soil and groundwater.
They play a crucial role in monitoring the fresh-salt distribution in the subsurface, especially in areas where saline water can threaten fresh groundwater.
Dawaco GW supports the processing of data from salt guards. For each monitoring point, the date of the measurement, a soil composition including resistance curve on that particular date, electrode pairs and corresponding depth, and EC curves are displayed.

QC (Quality Control) Protocollen
Several QC protocols are currently used in the Netherlands for validation of groundwater standings and groundwater quality data.
The BRO officially recognises eight assessment procedures:
- BrabantWater2013
- EijkelkampDataValidatie v0.0.9
- PMB Protocol Datakwaliteitscontrole QC2018 v2.0
- RWS AAT Grondwater v1.0
- Validatieprocedure Evides Waterbedrijf
- Vitens Beoordelingsprotocol Grondwater
- Wareco Water Data Validatie Protocol v20200219
- Waternet Beoordelingsprocedure
This list was recently expanded to include additional protocols, and is expected to grow with new insights in the future.
Dawaco deliberately chooses not to commit to one specific protocol, but offers a wide range of advanced validation tools.
This allows users to validate their data according to the QC protocol of their choice and deliver only high-quality data to the BRO.
Most checks and tests from existing protocols can be performed using Dawaco's functionality.
Import, export in reports
Dawaco supports both manual input and import of data from CSV files.
Columns can be flexibly linked to Dawaco fields, without fixed requirements for column names or order. Default values are filled in automatically where possible, including for BRO fields. The import function checks data for consistency and allowed values.
Errors are clearly logged. Users can add, modify or delete data, with the CSV format guaranteeing version independence. Thanks to its flexibility and robustness, this functionality is widely appreciated.
Supported Logger files
Dawaco supports several logger formats, including:
- TUF (Keller)
- MON (Van Essen Instruments)
- XLE (Koenders)
- JSON (Keller)
These formats are version-independent. In addition, pressure gauge administration is automatically maintained for many logger types (since Dawaco 2016). Data export & BRO integration Almost all data can be exported to CSV files (compatible with MS Excel) via the "Reporting" window.
Data subject to BRO can easily be exchanged in IMBRO-compliant XML files, although there is currently little demand for this from users.
Links to external databases
Dawaco offers a comprehensive data model and various functionalities, but is designed to work with rather than replace specialised systems.
Smart links make it easy to exchange data.
Dawaco is already successfully paired with:
- LIMS (Laboratory Information Management System) - Integration possible with any LIMS system on request.
- PLENTY / PI - Management of time series, such as historical data of flows and groundwater levels in pumping wells.
- SAP / ULTIMO - Systems for work order management, well and pump data, and maintenance logging.
Link with KNMI
Dawaco includes a KNMI module that allows standardised meteorological series to be imported directly.
This includes pressure measurements for absolutely measuring loggers and support for validation of groundwater levels.
