Capital Regional District directors voted Tuesday against a motion to delay the plan.
Those opposed cited worries federal and provincial funding would be withdrawn.
However, the directors are expected to consider another motion Wednesday asking the federal and provincial governments to join them in funding an environmental assessment of the plan.
Earlier this year, the federal government announced it would contribute about $253 million toward the cost of building a wastewater treatment plant in Esquimalt along with a second biosolids plant at the Hartland Landfill, which will convert solid waste into energy.
The funding will cover about one third of the $780-million cost of the project.Suggest a correction
