Investigating drainage routes and suspected misconnections
SouthFlow’s pollution-control page concerns drainage investigation and related work. Explain the observed problem, suspected connection and affected area. Available plans, photographs and earlier findings can help define whether inspection or tracing is relevant to the enquiry. A private drainage contractor does not determine every environmental or regulatory question.
This page is not a general air-quality, pest-control or noise-reporting service. If a site operator or relevant authority has specified investigation requirements, provide them before booking so the drainage work can be scoped. Avoid assuming that a connection has been confirmed solely from the location of an odour or visible water.
Set a clear investigation question
Identify the outlets, chambers or suspected route involved and explain what needs to be established. Dye tracing may help investigate connections, while CCTV inspection addresses visible internal pipe condition. Agree which methods and records are required and who can authorise access and any follow-up work.

Planning your drainage work
Can you investigate an unclear drainage connection?
Explain the suspected route and observed issue. Drainage inspection or dye tracing may help investigate connections, depending on the site and purpose.
What affects the cost?
The drainage condition, access, extent of work, preparation and attendance requirements affect the quote. Describe the job and ask which work and charges are included.
Do you cover the whole of Hampshire?
Yes. SouthFlow covers homes and businesses throughout Hampshire. See Hampshire coverage for locations served. The wider service area also includes Surrey and West Sussex.
Does this service certify environmental compliance?
Do not assume that an inspection certifies compliance. Share any requirements from the site operator or relevant authority before booking and establish whether the proposed drainage scope provides the evidence requested.
Can dye tracing help investigate a suspected misconnection?
It may help establish whether accessible drainage points are connected. The method and observation points need to suit the question, and further inspection may be needed to understand pipe condition or unclear results.
