Table of Contents
Quick Answer: What You Must Do
Key requirements: - Empty your tank every 1-3 years (depending on usage) - Keep maintenance records - Ensure proper discharge (to soakaway, not watercourse without permit) - Use licensed contractors for emptying
Key legislation: - General Binding Rules 2020 (England) - Bans septic tank discharge to watercourses from 1 January 2020 - Environmental Permitting (England and Wales) Regulations 2016 - Governs discharge permits - Water Resources Act 1991 - Pollution offences can result in unlimited fines and prosecution
Neglecting a septic tank can lead to blockages, pollution, fines, or legal liability.
Why Maintenance Matters
Prevents problems: - Avoids blockages and drainage backups into your property - Prevents soakaway failure from sludge overflow - Reduces emergency callout costs
Legal compliance: - Avoids pollution of waterways (a legal requirement) - Prevents fines and prosecution from environmental agencies - Ensures you meet your duty as a property owner
Practical benefits: - Ensures the system functions efficiently - Prolongs the lifespan of the tank and soakaway - Reduces risk of insurance claim rejection - Maintains property value
A well-maintained septic tank can last 20-40 years. A neglected one can fail within 10 years.
