Questions about Chigwell Road / Langston Road
- Who operates Chigwell Road / Langston Road?
- Thames Water is the operator named in the annual record. The permit reference is Permit applied for.
- Where does Chigwell Road / Langston Road discharge?
- The annual record does not provide a usable receiving-water name.
- How many times did Chigwell Road / Langston Road spill in 2025?
- The 2025 return records 19 counted spill events and 54.6 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.
- Can I trust the 2025 figures for this outlet?
- The monitor worked for 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Chigwell Road / Langston Road discharging right now?
- This record is linked to a company live feed. The panel above shows the latest report we hold, with its date. That report can be old, and the monitor can be offline, so check the date before relying on it. A report that no discharge is taking place is not a water-quality result.
- How accurate is the map marker?
- The marker comes from the grid reference in the official annual return, which is accurate to about 1 metres. It shows the recorded outlet position, not the extent of any discharge.
- What kind of outlet is Chigwell Road / Langston Road?
- The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
- How does Chigwell Road / Langston Road compare with other overflows?
- Chigwell Road / Langston Road recorded 19 spills in 2025. That is more than 62% of the 14,239 overflows in England with a reported figure, and ranks 5,217th nationally. Among Thames Water overflows it ranks 170th of 579; the median Thames Water overflow recorded 6 spills. Ranks compare counted spill events only. They do not compare volume or harm.
- Does zero spills mean the water was safe?
- No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
