Wastewater samples, 2019. The table includes both untreated and treated water; the final column identifies each sample. These historical results do not establish current water quality.

Editorial note: the original column headings and units below are preserved. Some labels use kW for quantities described as energy. Their meanings need checking against the original records; no corrected totals or energy-saving claims have been inferred.
I’m not totally sure what each column represents. The system is also not completely tuned in + the greenhouse lets cold air in. Calculated values are ~8000 kW per year, with more use of the wood burning stove the kWs should go down (BW – Apr 2019).
