View Annual Sewage Data

You're looking at the totals that we have calculated for sewage in Pontypridd for 2025. It is an estimate, based on very poor quality live data from the Water Companies. This may not align with the 'official' reported sewage values from the water companies, which is reported in April following then end of the year - so 2025 numbers are reported in April 2026.
