How property use affects the system
The same type of tank can behave differently depending on how a property is used. Seasonal occupancy, catering, shared washrooms or changes in building use can alter wastewater loading and the maintenance interval. The service pages explain the technical work in more detail.
Sectors: common questions
Should I use a sector page or a service page?
Use the sector page for issues linked to the type of property. Use a service page when you already know the work needed, such as emptying, cleaning or inspection.
Does the same emptying interval apply to every sector?
No. The interval depends on the installed system, its maintenance guidance and the amount and pattern of wastewater entering it.
Does a sector page confirm that an installation meets the rules?
No. Regulatory requirements depend on the actual system, discharge and location. General sector guidance cannot establish compliance for a particular property.
