What this means →
Why this one spills

This looks like a fault, not a storm.

This overflow has discharged in dry weather 49 times since 2020 — spills with no rainfall to excuse them. Its treatment works is not itself over capacity, so a catchment-wide explanation does not hold. Applied to this record, the two-stage lawfulness test is hard to pass: a recurring dry-weather discharge is not an exceptional circumstance, and where the remedy is routine maintenance the disproportionate-cost exception is hard to run.

How this verdict is reached →

Can its works cope?

Full capacity view →

This overflow drains to Totnes STW, serving about 10,832 people on a 3,967 m³/day permit.

38%
of permitted flow
Within capacity

The works has headroom — so spills here point to another problem, often on that branch of the network (a blockage, a failed pump or infiltration).

On our estimate the works has spare capacity for about ~17,500 more people before it reaches its permitted flow.

The same works has emergency overflows too

2 pumping-station emergency overflows feed Totnes STW works — raw-sewage relief outlets that should fire only when a pump fails. They are not in this page's feed; between them they have discharged about 0.05 recorded hours.

What you can do about this one

OPEN NOW

Ask for the data

Under the Environmental Information Regulations, Dartington Sch Two's telemetry, the works' flow-to-full-treatment setting, and any spill investigations are emissions information — they cannot be withheld on commercial-confidentiality grounds. A written request is the fastest lever.

BY 30 APR 2027

Get it into the next programme

Investigations that will shape the 2030–35 environment programme must complete by this date. Putting this overflow on the record now — to South West Water and the Environment Agency — is what gets it considered.

BY 1 NOV 2027

Put it in the drainage plan

South West Water's draft Drainage & Wastewater Management Plan goes to a twelve-week consultation. A named overflow with evidence behind it is far harder to leave out.

The record since 2020

49 dry spills and 252 pre-STW spills since 2020. Pick a year to see its events below.
