  • What it is
    The Gravois Arm Sewer District is in its third phase of construction which will extend sewer service to subdivisions around the end of State Route O, Towering Oak Road, Serenity Cove, Red Hollow Rd. and Lake Rd. 5-18. In addition to residences, South Elementary School and Coconuts Bar & Grill will go online. The current treatment plant for the Village of Gravois Mills will go offline. Once completed, the GASD will have about 880 users total, compared to almost 400 now. In addition to protecting the environment, officials believe the approximately $8.14 million expansion will help stabilize user rates.
    What's new
    After the three contracts covering the large scope of work were finalized in mid-January, construction crews had 270 days to complete the project and look to be on track to finish by the mid-September deadline, according to GASD board chair Dave Taylor.
    Overall, 54,000 feet of force main and 1,600 feet of gravity main lines are now in the ground, he said, along with approximately 25 grinder tanks out of a total of around 150.
    The crews have been installing grinder tanks at the good rate of two-three a day, Taylor said, thanks in part to the good weather.
    All the major lift stations in the southern part of the project are also in, according to Taylor.
    The area north of the treatment plant is mainly line work. It has been somewhat delayed by a large amount of rock work to prepare the ditch near Coconuts Bar & Grill as the line comes up from the lake on Red Hollow Rd. to March Rd.
    What's next
    Electricians are working to install control panels and disconnects on the grinder tanks that are place to make them operational.
    New customers are being put online as lift stations come online. A few new customers are already receiving service.
    In the Route O area, Millstone Townhomes has been put online, according to Taylor, and Tony's Point subdivision could be ready in as little as two weeks, depending on weather.
    The sewer line is nearing Lake Rd. 5-18 from the north, while the force main from Lake Rd. 5-18 south to the plant is in the ground.
    The few grinder stations in this area are not yet installed.
    The final grade work around the grinder tanks has not yet begun. After a presentation by Lake of the Ozarks Watershed Alliance executive director Donna Swall at its April 2 meeting, the district is encouraging homeowners to participate in LOWA's incentive program for low impact landscaping (LIL).
    Through a grant to help control storm water runoff into the lake, LOWA is offering cost-sharing incentives and discounts for homeowners to utilize LIL techniques in the cleanup of the sewer project. Visit www.sosLOWA.org for more information.
