## Frequently Asked Questions <a id="cite-faq"></a>

### How often does a septic tank need emptying in the UK?
Under UK Building Regulations Approved Document H2 and Environment Agency guidance, septic tanks should be emptied at least once every 12 months for average family households (3–4 bedrooms / ~3,800L) to prevent suspended solids entering the soakaway.

### What is an EA Section 34 Waste Transfer Note and why is it mandatory?
Under Section 34 of the Environmental Protection Act 1990, UK homeowners have a strict Duty of Care to ensure wastewater sludge (EWC 20 03 04) is collected by an Environment Agency Upper-Tier Waste Carrier (CBDU). You must keep your Waste Transfer Note for a minimum of 2 years to avoid statutory fines.
