The expected diversions and extractions are based on abstractions made from the connected surface water store during the current reporting period and the ongoing urban water access entitlement to ActewAGL.
Only the total urban water access entitlement volume has been included as a future commitment, as it is the only expected future commitment that will have an impact on the calculated connected surface water store asset. No assumption has been made in this table as to the actual volume of water that will be diverted under this entitlement.
Based on average historical data, future inflows to the reservoirs used for urban water supply are likely to be between 60,000 ML and 411,000 ML. On an average year, inflow to the reservoirs is 206,000 ML. Evaporation from the connected surface water store has not been included in this table.
