Blocked Drains in Falmouth
Falmouth operates a separate sewer system where foul and surface-water drains run independently, complicating blockage diagnosis. Victorian and Edwardian properties built across Falmouth's TR11 and TR13 postcodes often have misconnected appliances—washing machines, gutters, or sinks plumbed into surface water drains instead of foul. These misconnections are invisible until a blockage creates overflow or the Environment Agency flags a breach. Modern Falmouth properties rarely have this issue, but identifying and correcting misconnections is increasingly demanded by mortgage lenders and conveyancers.
Blocked drains in Falmouth are often caused by misconnected appliances in the separate sewer system (washing machines plumbed to surface water drains) or root intrusion in 80+ year-old clay pipes under Victorian properties. Survey and clearance identify the cause; relining prevents future blockages.
Drainage in Falmouth — what local engineers know
Falmouth's separate sewer system is a double-edged sword: fewer combined-sewer overflows during rain events, but higher risk of cross-contamination if appliances are misconnected. Cornwall Council and South West Water run annual compliance checks in TR12 and TR14, particularly after new development. The Environment Agency considers discharge of foul water into surface drains an enforcement issue; homeowners face fines if misconnections are discovered during property surveys. Falmouth's older Victorian stock is the primary source of misconnections—original plumbing was never designed for washing machines or dishwashers. Tree root intrusion also plagues Falmouth's Victorian terraced streets, where 80+ year-old clay pipes run under mature gardens.
- Water hardness (30–100 ppm CaCO3, soft) supplied by South West Water: South West Water is naturally soft (30–100 ppm CaCO3) — local ground conditions in Devon and Cornwall produces some of the softest mains water in England.
- Separate sewer system across most of Falmouth: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Falmouth means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- Parts of the Falmouth area fall within Environment Agency flood alert areas along the River Kenwyn corridor — sewer surcharge during prolonged rainfall is a known risk; non-return valves are worth considering.

Who's responsible for drains in Falmouth?
In Falmouth, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, South West Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Cornwall.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to South West Water rather than paying for the repair yourself. The separate sewer layout that dominates Falmouth affects where these boundaries typically fall, and our local engineers know the TR11, TR12, TR13 networks well enough to identify ownership quickly.
