About 80% of mainly Vernon customers receive improved secondary treated (UV disinfected) domestic water from Kalamalka Lake (the Mission Hill Water Treatment Plant or MHWTP). Treatment costs in 2011 amounted to $625,577 or $0.13 per cubic meter (based on 4,828,000 cubic meters of billed volume). In 2012 treatment costs were $524,475 or $0.12 per cubic meter.
The rest of the domestic customers received treated water from the Duteau Creek Water Treatment Plant (DCWTP). This water is clarified using the DAF treatment system and chlorinated and is about the same quality as water from the MHWTP prior to UV disinfection. Treatment costs in 2011 amounted to $1,702,202 or about $1.11 per cubic meter (based on 1,530,000 cubic meters of billed volume). In 2012 treatment costs were $1,451,830 or $1.06 per cubic meter.Two observations are clear:
1. The water treatment at the MHWTP is of higher quality than that of the DCWTP and
2. The treatment costs of the lesser treated water at the DCWTP is still in the order of 7.5 times higher per cubic meter than the secondary treated domestic water at the MHWTP. Note that only a very small percentage of the water treated at Duteau Creek is for Domestic Drinking water consumption. A total of 13,375 megalitres of water were treated at the DCWTP, with an operating cost of $1.7 million dollars. In the peak demand of summer 2011 the plant treated 160 megaliters of water per day. In the winter time, the water treatment plant only treated around 6 megalitres per day. That means that in the summer of 2011, approximately 96 % of the water treated at the DCWTP, was used for outdoor sprinkling and irrigation purposes .
3. Most of the funds spent on treatment at the DCWTP is wasted on agriculture irrigation since irrigation water customers are not charged for the treatment costs, as the treatment is not needed for agriculture, then these costs are passed on to domestic customers only.
Conclusions
The first major unintended consequence is that domestic customers are now paying at least four times as much for a cubic meter of water as they did prior to the year 2000. Current costs are about $1.80 per cubic meter if they use a lot of water and about $4.72 per cubic meter if their consumption is 20 cubic meters per quarter.
The second major unintended consequence is that agriculture customers with agricultural land classification and agriculture water allocation must fulfill rigorous requirements in order to receive the low rate for their land. Without affordable agricultural water there is no agricultural land in the Okanagan.This has issue raises another problem. If a landowner does not get affordable water for his land, theoretically, he might apply to have his land removed from the land reserve. This would jeopardize the intent of the agricultural land reserve act.
“Separation of the existing combined water system will provide the most cost effective water management in the long term."Initially, all concerned endorsed the plan. For political reasons this direction was changed in 2004 and, as the authors of the 2002 MWP predicted, we have been paying for the water dearly and will continue to do so in the future. Plans for the future include filtration treatment at both the DCWTP and at the MHWTP resulting in even more expensive water to be used for agricultural irrigation.
