An independent guide to private-house sewage. Not a manufacturer, seller or installer, and not affiliated with the QUBO brand or the former site on this domain; design and installation are done by professionals.

Reading paths

A reading path arranges the pages of this guide into a short route for a particular situation. Instead of reading everything in turn, pick yours and follow the links in order: the basics first, then what will help when you talk to professionals.

A cottage used at weekends and a house lived in all year ask very different things of a sewage system. The same system can suit one owner perfectly and constantly frustrate another, so the place to start is an honest description of how you actually live there.

— Editor's note

Reading paths include only published pages. The order is chosen so that each page builds on the one before, and the "Basics" and "In depth" labels show where the text covers core concepts and where it goes into detail.

What this text is based on

  • SP 32.13330 "Sewerage. External networks and facilities" (Russian code of practice)
  • Equipment manufacturers' instructions (general provisions)

Rules, requirements for treatment facilities and equipment manuals are updated from time to time, so the final word belongs to the design, the regulations in force and the documentation of your particular system. The texts here cite Russian standards; other countries have their own building and sanitary rules, so check local regulations and permits. This guide explains how systems work and why decisions are made, but it does not replace a designer, an installer or a service company.
