Detail of score

The data are calculated with improvements, evidence and connections currently published in EkoPulse.

Model used for this calculation: Impact 2.0 · Reliability 1.3.

Impact: 37 points

Cumulative score

Provisional model: each improvement is assessed by its reach for this profile type, from symbolic to transformative. The same work counts once. Contributions are combined with diminishing returns, and relevant relationships are added. Evidence adds 0 direct Impact points. This does not measure tonnes or net impact.

The highest reach levels require human confirmation; until then they receive a conservative rating. New or edited improvements use a provisional level until their current text is reviewed.

0 improvements with evidence+0
1 ecosystem connections+0.05
Profile’s own base37
Ecosystem influence+0
Total impact37

The own base combines practices and direct relationships. Direct relationships and ecosystem influence together add at most 4 points. Ecosystem influence can extend up to 3 steps away and depends on relationship trust and nearby profiles’ data. A disputed relationship transmits no influence through the graph, although it can retain direct credit if its category is eligible. Relationships do not generate negative points.

The advisory thresholds are 25 profiles with improvements, 5 with at least 25 points and at least one reaching 95 points. The current figures are 112, 34 and 72, respectively. Reaching these thresholds does not activate comparison: it requires a model decision.

Reliability: D

4 / 100

The model first places the information in a band according to its supporting evidence. It then calculates the score within that band.

Contributions are shown rounded; the total uses the original calculation before final rounding. Ecosystem support is already included and is not added again. Under the current model, the maximum attainable is B+ (84/100).

Evolution of the score

The public record has just begun: for now there is only a catch to show an evolution. The next captures will be drawing how this score changes over time.

EkoPulse scores are recalculated as the available information changes and the evaluation model evolves. Methodological improvements may result in changes in the score that do not necessarily reflect an equivalent change in profile performance.

Energy

Energy
Zeanuri hydroelectric power plant: energy use of the Zadorra system (since 1998) Added by EkoPulseFirst hydroelectric installation of the Consortium, in operation since 1998: the water destined for the high sale potabilizer is diverted by-pass and passes through two turbines, with an estimated production of 5.47 GWh/year in dry year and 7.98 GWh/year in wet year. Since its launch, it has produced more than 144 GWh.

Water

Water
Environmental monitoring plans for treatment plants (12 EDAR + Urdaibai, published annually) Added by EkoPulseMulti-annual monitoring programmes for estuarine and marine water bodies to which the main EDARs of the Consortium (Galindo, Bakio, Ea, Elantxobe, Gorliz, Laga, Laida, Lamiaran, Lekeitio, Lemoiz, Muskiz, Ondarroa), with systematic measurement of the water column, sediment, phytoplankton and benthic communities, plus an annual assessment of the ecological status of Urdaibai communities; reports 2023, 2024 and 2025 are published.

Community and persons

Community and persons
Free programme of visits and education on the urban water cycle at the Consortium facilities Added by EkoPulseRenewed programme of free visits to water supply and sanitation facilities, open to schools and training courses, groups and associations, general citizenship ("Know the Water Consortium") and summer colonies, with extended hours and weekends, in order to raise awareness of the collection, supply and purification and to raise awareness about the reasonable use of water.
