Measures on record
The legally binding measures the water company must deliver in this catchment â what each requires, and what to watch.
These measures are legally binding. Each one is a dated, site-specific requirement the company must deliver.
The Water Industry National Environment Programme is how the Environment Agency turns statutory duties into named obligations at named sites, with a completion date attached. Where a measure requires a physical upgrade, the Agency writes the result into the site's environmental permit â and from that point the requirement is criminally enforceable.
The measure itself is public. What is not published is the water company's action to comply with it â its delivery is reported to the regulator and scored, but the underlying work, and whether a measure has actually resolved the problem on the ground, is not on the public record. What to watch is slippage: a measure can be re-dated or re-scoped, and until the permit is varied the obligation has not changed.
What the types mean
A physical upgrade â bigger storage, better treatment, more capacity. This is the only type that actually fixes the problem on the ground.
A study of the cause. It produces a report, not a repair â an investigation must lead to an improvement before anything changes.
Installing or running instruments to measure the problem. Necessary evidence, but on its own it fixes nothing â it too has to be followed by an improvement.
So an overflow whose only measures are investigations or monitoring is being looked at, not yet fixed. On the gaps page, only a measure that is still active counts as action â a measure completed while the overflow is still failing does not.

56 of 56 measures shown. A measure whose completion date has passed is shown as Complete; the water company's actual delivery against it is reported to the regulator but not published here.
There is no public change log
The live WINEP spreadsheet is internal, and there is no versioned public comparison or published reasons when a measure is re-dated or dropped. The only way to hold slippage to account is to archive every annual release and diff it yourself.
The 2027 pressure point
Most investigations must complete by 30 April 2027 to feed the 2030â35 programme. That date â not 2030 â is the one to hold: an investigation that slips past it cannot shape the next round of funded schemes.
