MainOps: The Digital Platform Redefining Groundwater Project Management
In an industry where a missed measurement, a lost daily log, or a disputed task completion can cost time, money, and trust, the question of digital documentation has never been more important. Large-scale groundwater lowering and drilling operations involve hundreds of moving parts — wells, pumps, generators, water treatment units, site teams, subcontractors, and clients — all generating data that needs to be captured, verified, and acted upon in real time.
Hölscher Jensen, the Danish groundwater specialist, has spent years building the answer to that challenge. The result is MainOps: an advanced online platform developed entirely in-house, born from the ambition to create a digital platform to help keep a structured, real-time overview of tasks and documentation related to maintenance and operation.
What began as an internal tool has evolved into a comprehensive system that is now a core part of how Hölscher Jensen delivers its projects — and a compelling case for why the wider dewatering industry should be paying attention.
| Tendering & Planning | Safety forms, toolbox meetings, and planning documents recorded from day one |
| Mobile Task Management | Employees access daily schedules via smartphone; completed tasks logged in real time |
| QR Code Measurements | Water levels, pressure, and flow recorded with date, time, and GPS coordinates |
| SCADA Integration | Measurements transferred directly for sensor calibration and data verification |
| Automated Invoicing | Approved tasks seamlessly transferred to invoicing with no additional handling |
| GPS Tracking | Rental units tracked on site; service checks verified by GPS location |
What is MainOps?
MainOps is a cloud-based project management and documentation platform purpose-built for the complexities of drilling and groundwater lowering operations. Unlike generic project management software adapted for construction use, MainOps was designed from the ground up by people who understand dewatering — and it shows.
From First Document to Final Invoice
The MainOps workflow begins at the very start of a project. Tendering documents, planning files, safety forms, and toolbox meeting records are all captured directly in the platform from day one. This means that by the time a project breaks ground, there is already a full, auditable record in place.
As work progresses, daily logs, site trials, pump tests, water quality samples, and individual work tasks are all stored automatically in the database. When a task is completed and signed off by the site manager, it is seamlessly transferred to the invoicing module — no re-entry, no chasing paperwork, no risk of items falling through the cracks.
For project managers overseeing multiple simultaneous projects — a common reality in Hölscher Jensen’s world, where the company operates large-scale infrastructure projects such as the Nordhavn Tunnel in Copenhagen — this level of integration is transformative.
Real-Time Measurements via QR Codes
One of MainOps’ most distinctive features is its use of QR codes for real-time field data capture. Site operatives use a smartphone or tablet to scan a QR code at each monitoring point, immediately logging water levels, pressure readings, and flow rates with an automatic timestamp and GPS coordinates.
This data is transferred directly into the SCADA system for sensor calibration and instrument verification. The result is what Hölscher Jensen describes as “an irrefutable record”: a verified, timestamped, location-confirmed dataset that eliminates any ambiguity about whether measurements were taken correctly and on schedule.
The same QR-code-based system applies to service checks on generators and water treatment units. Rental periods are automatically initiated when equipment arrives on site, and managers always have full visibility of how many units are deployed and precisely where they are located.
“Water levels, pressure, and flow are continuously documented with date, time, and GPS coordinates — creating an irrefutable record that eliminates any doubt about whether measurements were carried out correctly and on time.”
Keeping Field Teams Connected
MainOps bridges the gap between the office and the field in a way that genuinely changes day-to-day operations. Project managers assign tasks directly within the system; field employees receive their daily work schedules on their smartphones or tablets. Once tasks are completed, employees log their feedback through the app, creating a continuous loop of real-time communication and coordination.
On large, multi-team projects spanning several work fronts simultaneously, this means that the project manager always has an accurate, up-to-the-minute picture of what has been done, what is in progress, and what remains outstanding — without needing to rely on phone calls, paper timesheets, or end-of-day catch-up meetings.
Why It Matters for the Industry
The dewatering sector has traditionally been slow to embrace digital transformation. Many contractors still rely on paper logs, spreadsheets, and manual data entry — processes that introduce error, delay accountability, and create friction between contractors and clients when disputes arise over task completion or measurement accuracy.
MainOps addresses all of this directly. By combining automation, digital documentation, and real-time data in a single platform, it sets a new standard for what project management in the groundwater sector can and should look like. It improves safety through better documentation, enhances quality through verified records, and strengthens accountability through full traceability from start to finish.
Importantly, it also protects the client relationship. When every task is documented, every measurement is verified, and every invoice is automatically generated from approved work records, the conversations between contractor and client can focus on the project itself — not on paperwork disputes.
A Platform Built by the Industry, for the Industry
MainOps is not a product bought off the shelf and adapted for dewatering use. It was conceived, designed, and built by Hölscher Jensen’s own team — people who have spent their careers on dewatering projects and understand exactly what information needs to be captured, when, and why. That context is evident in every feature.
As the dewatering industry faces growing demands for transparency, sustainability reporting, and digital accountability from clients and regulators alike, platforms like MainOps point the way forward. Hölscher Jensen has not just built a better tool for their own operations — they have demonstrated what the future of groundwater project management looks like.
The platform consolidates the entire project lifecycle into one place: from tendering and initial planning through to daily operations, monitoring, and final invoicing. Every stage is connected, every record is traceable, and every piece of data is stored automatically and securely.
