The political struggle regarding the moraine continues. The community of King City in King Township has been embroiled in a decade-long argument about replacing septic systems with a sewerage connection to the Durham-York Sewage System. Proponents of the link claim that the septic systems leak, endangering the subterranean aquifers of the moraine. Opponents claim that such a link would enable explosive growth in the small community, which would be detrimental to the preservation of the moraine. Construction of the link began in early 2005, creating the main sewer trunk from King City to Oak Ridges along King Road, connecting to the existing system near Yonge Street.
