May 2009 : Since August 2007 the QWC has applied restriction measures and the requirements are now generally available to the public. This section is now redundant in favour of the updated requirements that we must adhere to. ******************************************** Now redundant but retained for interest
The final calculation is slightly in excess of 1000ML per day. The SEQ Regional Plan part B uses the expression " business as usual "term which to my understanding means - without restrictions of any kind and before the "Emergency measures" as described and Legislated in the Water Commission's web-site. The Requirements are measured on that basis. In the first instance, the Population serviced by the The second requirement was to adopt the SEQ RP Part B method being "per person including Commercial and Industrial at 450 litres per day each". There are adjustments made by me to cater for the Commercial and Industrial from the main Dams. The revision is 474 litres per person per day. The break-up is 300 litres Domestic and 174 Commercial and Industrial. The third aspect of the Requirements was to measure the calculation with annual depletion of the Dams together with minor estimates of rainfall. These estimates are fully covered in " Rainfall 2001-06" button. You will see from the attached document that the requirement calculations are within tolerance of the annual totals of the depleted Dams together with rainfall in both "low" and "high" yield years. It was interesting and understandable that in a high rainfall year as 2004, the requirements dip by as much as 6% of capacity. This could well have been the situation in the years 1986 to 2000 covering up to 5 uncommon events. The year 2004 has an accurate assessment of the Megalitres that inflow created. See "Wivenhoe Dam" button. Confirmation from the South East Queensland Regional Water Supply The SEQRWSS stage 2 interim report attached confirms This 374,000ML a year converts to 1024ML per day which agrees
with my calculated requirements. The supply from This amounts to a shortfall of 198,000ML each year until uncommon events. Those who follow the "drought" mantra, without thought, will have their calculations severely distorted. 300 Litres Domestic. Further considerations. Attached is an extract from a water tank supplier's brochure. They have been in operation for 14 years and service an area from Bundaberg to the Victorian border principally to Country clients. The relevant part is the normal household requirements to be calculated when determining the size of your water tank. It reveals to us that the normal requirements per
person is
The calculations are also available for those who aspire to self sufficiency. There has been a recent move by our Brisbane Lord Mayor to limit the rebate on water tanks to those who link them into household use ( June 2007 ). This is entirely compatible with these conclusions. Water Commission The public stated aim of the Water
Commission is to reduce the level of water use to 700ML per day. They are I have not studied the surrounding aspects of water releases but it obviously plays a part. The calculated 1003ML per day requirement is maintained. Conclusion The current water requirements from the Wivenhoe and Somerset Dams to resume normal living is a conservative 1003ML per day.
