This is what you know as a drainage specialist

50–70 % more emergency jobs won
Emergency calls about blocked drains

A blocked drain is an emergency. The customer wants help NOW. The AI triages: urgent → it calls you. Ordinary question → it books a slot. You lose fewer emergency jobs.

Stormwater separation is a municipal order

Many municipalities require separation before 2030. The AI can automatically identify customers who still need it and offer an early site visit. You build a pipeline.

Authorisation documentation per job

Drainage work requires the authorisation certificate to be documented per job. The AI keeps track of your authorisation, documents every job, and can export to the Danish Safety Technology Authority.

The AI phone — your backup

Hear what happens when you can’t pick up the phone yourself

You take the calls you can. But when your hands are full, the AI takes over: it answers in Danish, understands what drainage specialists get called about, books the time and sends you a summary. You stay in control — it’s your backup, not your replacement.

  • Urgent cases are forwarded to you straight away
  • Books directly in your calendar — only in free slots
  • You get a summary by SMS, so you always know what was agreed

How Online Erhverv helps drainage specialists

An AI phone with drainage triage

"The toilet is overflowing" → urgent, it calls you. "We want separate stormwater drainage" → planned site visit. The AI knows the difference.

Separation pipeline

Load in your customer database with addresses. The AI checks municipal separation requirements and suggests an early site visit for the properties that still need it.

Authorisation documentation

Every drainage job is automatically documented with the authorisation certificate, date, work carried out and photos. Exportable to the Danish Safety Technology Authority and the municipality.

The difference in your week

What the day looks like as a drainage specialist — before and after

How it is today
  • Emergency floods ring in while you're down in a manhole
  • The CCTV inspection footage is scattered and has to be dug out manually
  • Insurance and municipal cases need documentation you gather by hand
  • Groundwork is planned on a whiteboard — machines and people in your head
  • Quoting and invoicing a service connection drags on for weeks
With Online Erhverv
  • The AI prioritises emergency call-outs and rings you straight away
  • CCTV inspection and photos sit together on the job — easy to pass on
  • Documentation for the insurer and municipality is ready from the job photos
  • The groundwork is planned with people and time in one calendar
  • The quote becomes an invoice that's posted the moment the job is closed
The whole platform

Not just an AI phone — your whole business in one place

From an emergency flood to a CCTV inspection and insurance claim — the drainage specialist's documentation and call-outs gathered.

“I lost calls every day, and quotes sat unfinished until late at night. Now the AI answers the phone when I can’t, and the whole business is in one place. I’ve got my evenings back — and customers don’t move on to the next one.”

FAQ

Frequently asked questions

The questions drainage specialists ask most before getting started. Missing yours? Call or write — you’ll talk to a real person who knows the trade.

Still unsure?

Frederik will happily show you what it would look like for your business — free, no sales talk.

Can the AI tell an emergency blockage from planned work?

"The toilet is overflowing" or "water is coming up out of the drain" → urgent, it calls you. "We're thinking about separating the stormwater" or "a new connection for a build" → planned, it books a site visit. The AI asks follow-up questions.

Do you keep track of the authorisation certificate per job?

Yes. We store your authorisation certificate number and document every drainage job with the date, customer address, work carried out and photos. It can be exported to the Danish Safety Technology Authority and the municipality.

Can the system identify customers who need to separate their stormwater?

Yes, if you load in your customers' addresses. We check against municipal separation requirements (Aarhus, Copenhagen and Aalborg have deadlines in 2027–2030 in most areas), and the AI suggests contacting them.

Can the AI help with documentation for municipal permits?

Yes. We have templates for the most common municipal applications (separate stormwater, new drainage connection, perimeter drain replacement) that the AI can pre-fill from the job data.

Are before/after photos kept for 10 years as the law requires?

Yes. All photos and documentation are kept for 10 years, securely in a Supabase database (EU server). That meets the Danish bookkeeping act and the authorisation documentation requirements.

What does it cost for an authorised drainage firm with 2 tradesmen?

The Pro plan (1,995 DKK/month) is the usual choice — 5 users, unlimited bookings, 200 AI calls and the full authorisation documentation module. For larger firms with 5+ people, Enterprise (3,995 DKK/month) is a better fit.

Can I order pipes and fittings directly from Sanistål or Brødrene Dahl?

Yes. Material needs are gathered per job (pipes, manholes, fittings, concrete rings), and you can send the order straight to Sanistål, Brødrene Dahl or other Danish wholesalers.
