Thank you for your recent enquiry for a sewage system compliance/condition check. You have advised that you require a basic survey which includes: - Carrying out an assessment of your current tank and discharge to advise if the system is compliant including x1 hour onsite - Report on compliance of your system - Report on condition of your system - Remedial options and costs if required - Dye test of all accessible downpipes/guttering at ground level Please note that the results may be inconclusive depending on the normal working levels within the tank, access to the outlet and access to the downpipes. If you have had any issues in the past with your unit, we would recommend that you have a desludge of the system at the time of our visit as a minimum. Please speak to us if you are not sure what level of survey is required.
