Plumbing and drinking water hygiene

Aurora Engineering designs plumbing systems with a focus on drinking water hygiene: potable water installations to DIN 1988 and VDI 6023, hot water generation with Legionella protection, foul and rainwater drainage to DIN 1986, fire-fighting water supply and special media for laboratory and hospital areas.

Water is essential to life and a hygiene risk in buildings when pipes are wrongly sized or water stagnates. We design potable water networks so that water flows, temperatures are right and operators can meet their obligations under drinking water regulations.

Scope of services

What we design in plumbing

  • Potable water installation

    Pipe network calculation to DIN 1988-300, material selection, circulation, flushing concepts against stagnation.

  • Hot water and Legionella protection

    Central and decentralised hot water generation, temperature maintenance, ultrafiltration, sampling points.

  • Drainage

    Foul and rainwater to DIN 1986-100, lifting stations, backflow protection, grease separators, roof drainage.

  • Rainwater and greywater

    Use, infiltration, retention and coordination with landscape design and drainage applications.

  • Fire-fighting water and extinguishing systems

    Wall hydrants, fire-fighting water transfer, separation stations, coordination with the fire safety concept.

  • Special media

    Ultrapure water, compressed air, vacuum, technical and medical gases, laboratory drainage with neutralisation.

Standards and guidelines

Standards, key figures and quality

Standards and guidelines

  • DIN 1988 and EN 806 (potable water)
  • VDI 6023 (hygiene) and DVGW W 551 / W 553
  • German Drinking Water Ordinance

  • Backflow protection and rainwater retention verified

Frequently asked questions

Frequently asked questions about plumbing design

How do you prevent Legionella in potable water installations?

Through temperature maintenance, short pipe runs, circulation without dead legs, series or loop installation and a flushing concept for rarely used outlets, documented in the hygiene concept to VDI 6023.

Do you also design rainwater retention?

Yes. Retention, infiltration and use are part of our drainage concept and are coordinated with the municipal drainage application.

Which special media can you design?

Ultrapure water, compressed air, vacuum, technical gases, medical gases to EN ISO 7396 and laboratory drainage with neutralisation systems.
