Oakwood City Council voted Monday night to apply for a grant to help pay for a sewer system that would serve an apartment complex where a septic drain field has been failing for years. The project at the 20-unit Hidden Valley complex off McClure Drive would involve laying 1,340 feet of gravity and force-main lines and construction of a pump station, costing $120,000 to $140,000, City Manager Stan Brown told the council. To take an edge off the cost, Brown said he hopes for up to a $50,000 “Immediate Threat and Danger” grant from the Georgia Department of Community Affairs.
