Drain Jetting in Hounslow
Hounslow's dense residential and commercial environment demands proactive drain maintenance. The town's separate sewer system across postcodes TW3–TW6 means foul and surface drains must be kept clear independently; grease accumulation in business drains is a leading cause of blockages and Hounslow Council enforcement notices. Thames Water supplies moderately hard water (5.8 °dH), which contributes to mineral buildup in older Hounslow clay pipe networks.
Drain maintenance in Hounslow (TW3–TW6) includes monthly grease-separator emptying for commercial premises under Thames Water regulations, annual CCTV inspection of Victorian clay pipes, and surface-drain clearing. The town's separate sewer system requires foul and surface drains to be maintained independently. Hounslow Council enforces compliance; violations trigger notices.
Drainage in Hounslow — what local engineers know

Hounslow Council manages environmental health and can serve notices on commercial premises where grease separators are not maintained—restaurants in Hounslow must empty grease traps monthly. The town's separate sewer system is critical: surface water maintenance is often overlooked, but blockages cause flooding in Hounslow's tightly packed streets. Victorian properties with clay pipes require annual inspection due to root and settlement risks in Hounslow.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Hounslow
- Separate sewer system across most of Hounslow: 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 Hounslow means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With a significant share 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.
- Hounslow has Environment Agency flood warning areas nearby along the River Thames corridor — basement and ground-floor properties can face sewer backflow during heavy rain; non-return valves are strongly recommended.

Who's responsible for drains in Hounslow?
In Hounslow, 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, Thames 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 Hounslow.
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 Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Hounslow affects where these boundaries typically fall, and our local engineers know the TW3, TW4, TW5 networks well enough to identify ownership quickly.
