If the Property is in England and you answered Yes to question 12.5 and your septic tank discharges directly into surface water, you must do one of the following as soon as possible:
• Connect to mains sewer
• Install a drainage field (also known as an infiltration system) so the septic tank can discharge to ground instead
• replace your septic tank with a small sewage treatment plant
You must have plans in place to carry out this work within a reasonable timescale, typically 12 months.
