Water Billing by Ward
The annual amount of water billed in each ward is reported as well as the number of water accounts, both residential and commercial.
N.B. One cubic metre of water (m³) is 219.97 imperial gallons. Accounts with billing data less than 6,000m3/year are deemed to be residential and are billed on a tri-annual basis (For example a variety store would probably be considered "residential" ). Accounts with billing data greater than 6,000m3 per year are billed on a monthly basis and are deemed to be "commercial". Residential readings are taken three times a year and commercial readings are taken once a month. The data will be useful in trend analysis. Some accounts are not mapped to a political ward and therefore their consumption is not included. The excluded figures are small enough not to affect an overall trend analysis.
