changing technology pushes up estimated cost of metro vancouver sewage plant - purified air

The Lions Gate sewage treatment plant is currently a primary treatment plant and plans to rebuild the sewage treatment plant to treat the sewage into a secondary standard.
The Vancouver Metro has chosen a plan for the Lions Gate secondary sewage treatment plant, and the estimated cost is now $0. 3 billion higher than originally estimated.
Fred Nenninger, project manager at the plant, said on Thursday that the $0. 4 billion initially expected was based on an estimate of 2007 of the cost required to build a liquid waste plant.
But the new technology makes the cost much higher.
"The technical team is still looking at the cost estimates we would like to provide to the utilities commission in November, but the current budget is within the range of $0. 5 billion to $0. 7 billion," he said, combined with the projected cost for 2018, to reflect the year in which the North Gate Regional plant in northern Vancouver is expected to start construction.
The design was selected from three shortlisted options that the technical team began reviewing in July.
Nenninger said they have narrowed the scope to an option, but there are still some details that need to be finalized before submitting the report to the Commission.
He said the cost of the option was the highest.
All three proposals are valid.
Other options, he said, use more advanced technology, which will increase the initial capital cost by 75 and double the annual operating cost.
"When we look at the different technologies in these three situations, the forward technology we choose is the one that provides today's secondary treatment needs," he said . ".
The planned technology will allow for later upgrades in the event of future changes in environmental regulations.
The factory will also produce creatures
Gas and energy removal from sewage.
The factory will include air, he said.
In order to solve the odor problem raised by the relevant residents, scrub the unit.
"Only clean air is discharged.
We had a lot of conversations with the local community about ensuring good smell management.
"The Metro Commission has not yet decided how to share the costs, but Nenninger said they proposed that the Metro adopt the model used by the Iona sewage treatment plant.
This means that the fee will be allocated to the sewage treatment area in Vancouver and North Vancouver, while the remaining 70 will be dispersed throughout the area.
The Vancouver Metro is also seeking millions of federal funds to upgrade the Lions Gate and the Iona sewage treatment plant.
The Lions Gate treatment plant will be rebuilt first, requiring the federal government to provide about $0. 133 billion in three monthsway cost-
Share the foundation with Metro and the provincial government.
