Wyndover Lake

The 1st phase of this project consisted of 35 lots adjacent to Wyndover Lake, a 108 acre tract located on Hwy. 61 in Colleton County, S.C. The 55 acre lake was originally created by a sand mining operation that significantly altered the natural shallow groundwater table. A large portion of this project area had been filled with mining spoil, further complicating the current shallow hydrology.

Initially, Land Management Group of S.C., LLC (LMG) conducted a feasibility study for the client to evaluate the soils’ potential and limitations for disposal of domestic wastewater. This task included measuring the saturated conductivity of a 4 acre area that was considered for a community wastewater system. LMG monitored 11 shallow wells and the lake level to establish the current Zone of Saturation for the proposed individual drainfields. Rainfall data was also collected and included in the overall hydrology modeling .

LMG was then contracted to provide 35 Soil Reports for Specialized individual on-site wastewater systems per SC DHEC Program 362/610. Detailed soil profile descriptions were collected for each lot’s individual infiltrative area.
These reports were written and certified by John Thorp, a licensed professional Soil Classifier. Mr. Thorp recommended site-specific “cut & fill” prescriptions to achieve uniform infiltration of the highly treated wastewater, which will be dispersed via pressurized subsurface drip-tubing. LMG also performed an analysis of the potential for “mounding” of wastewater below individual drain fields to ensure that the recommended daily loading rates were appropriate.

Next, the engineers at HEG Engineering used the Soil Reports to design complete wastewater treatment and disposal systems matching each lot's soil characteristics. The professionals at HEG and LMG will provide construction inspection services to insure that treatment system and drainfield construction is completed in accordance with the design and permit requirements.

SCDHEC approved the client’s 35 permit applications, which we consider a precedent-setting recognition of expert soil science and hydrology.
