Questions about Ripponden/STW/3Xdwf Overflow
- Who operates Ripponden/STW/3Xdwf Overflow?
- Yorkshire Water is the operator named in the annual record. The permit reference is E741(SS).

- How many times did Ripponden/STW/3Xdwf Overflow spill in 2025?
- The 2025 return records 56 counted spill events and 1,311 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?

- Is Ripponden/STW/3Xdwf Overflow 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 Ripponden/STW/3Xdwf Overflow?
