We answer your questions

A drainage system is a set of infrastructures designed to collect, channel, and evacuate rainwater, wastewater, or industrial water, preventing accumulations and potential damage to surfaces or buildings.

Household drainage directs water from sinks, showers, and sanitaryware through pipes connected to the sewerage network or a septic system. It also includes rainwater drains to prevent flooding on roofs and patios.

Drains can be classified as:

  • Surface (channels, gullies, gratings).
  • Subsurface (perforated pipes, drainage wells).
  • Rainwater (systems for collecting rainwater).
  • Foul Water (sewerage networks for wastewater).

Drainage water can be directed to the municipal sewage network, wastewater treatment plants or, in some cases, to on-site filtration and reuse systems.

At Inza, you can purchase our products through our online store or by contacting our team for customised solutions. We offer technical advice, tailored quotations, and secure delivery of products according to your project’s needs.
