Blocked Drains in Melksham
Melksham's separate sewer system dates back over a century, leaving many Melksham homes—particularly Victorian and Edwardian properties—vulnerable to misrouted surface water drains. Kitchen and bathroom blockages in Melksham can escalate quickly, especially when washing machines are plumbed into the wrong drain line. In Melksham postcodes SN12 and SN13, recurring blockages stem from limescale accumulation in soil pipes and laterals serving Victorian terraces.
Blockages in Melksham typically stem from hard water deposits in clay pipes, misconnected surface water drains, and tree roots invading old sewers. Melksham's Victorian stock is particularly susceptible. CCTV surveys identify root causes in Melksham's separate sewer system, enabling targeted unblocking.
Drainage in Melksham — what local engineers know
Melksham falls under Wiltshire Council and is served by Anglian Water. The town's 1960s housing expansion introduced mixed drainage configurations across postcodes SN14 and SN15, creating a patchwork of combined and separate systems. Wiltshire Council has issued enforcement notices regarding misconnected drainage in Melksham, where washing machines plumbed into surface water sewers are common. Melksham's hard water supply accelerates limescale buildup in soil pipes, leading to pinhole blockages. Anglian Water publishes regular advisories about drain misconnections across Melksham.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Melksham
- Separate sewer system across most of Melksham: 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 Melksham means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 32% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Melksham?
In Melksham, 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, Anglian 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 Wiltshire.
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 Anglian Water rather than paying for the repair yourself. The separate sewer layout that dominates Melksham affects where these boundaries typically fall, and our local engineers know the SN12, SN13, SN14 networks well enough to identify ownership quickly.
