Its purposes are to be a web-based information resource for local people and visitors and to develop as a digital archive of local material.

Current conditions and annual weather data are available for the upper Senni Valley, 1 mile south of Heol Senni, from a Davis 'Vantage Vue' weather station which is maintained by the Webmaster. Graphs are available of the weather in Senni during the previous week, the previous month and the previous year.
Measurements by the Webmaster of the water quality of the upper Senni river at Heol Senni and on the wooden bridge to the South, over the last two months, have shown no increases in phosphate, nitrate, nitrite or ammonia above normal levels. This is part of a citizen science project coordinated by the Wye and Usk Foundation.

Contributions to this community web, which has the alternative domain names of senni.org.uk, senni.uk, senni.wales and senni.cymru, are welcome and should be sent to the Webmaster.
