What this check answers

The technically possible solution depends on local planning, groundwater, soil, plot layout and the municipality’s sewer arrangements.

What to verify

  • Check MPZP or WZ requirements and ask the municipality about sewer availability and local obligations.
  • Have ground and water conditions assessed for the proposed location.
  • Confirm notification, permit and operating duties with the competent authority and system designer.
