Scope of work: Find a solution on how to direct heavy water flow during rainfall events to alleviate erosion and stop pond seepage.
The outcome of the project includes reestablishing the pond depth by cleaning out the sediment and debris while addressing the erosion from years of non-maintenance & best management practices (BMP) programs. A bonus of cleaning out a pond is it increase the capacities, but at the same time enlarges the pond from a small 12,000 square foot pond to a 20,000 square foot pond.
Root cause analysis: During rain events, water flows past the intended entry point of the pond and enters a narrow ditch. This quickly erodes the south bank and entry road to the home site, putting valuable property in jeopardy.
PondMedics provided calculations for surface water needs, requiring enlargement in the width and elevation of the inflow stream. For the high amount of flow, that included installing hard armor products from Hanes erosion “Flexamat”, enlarging the overflow and drainage structures.
Along with correcting drainage, erosion, and sediment build-up, a major need in North Texas was to seal the pond from seepage, leaking valuable rainwater out in a weeks’ time frame. PondMedics used the “ESS-13” product for this project specifically. The major processes in applying “ESS-13” after manual removal of unwanted materials is to 1) moist soil and then till the subgrade with a dozer, 2) use a water vessel to mix water and “ESS-13” in a mobile tank and distribute the mixture on the slopes and bottom of the pond, 3) a second tilling followed directly with a compactor. After this process, lightly grade the uneven soils into a complete stage on the final grade, Seed & “Curlex” the slopes, and finally refill the pond.

For best results with using “ESS-13”, in any situation, is to drain the pond and remove the sediment and establish the desired depth and pond slope for longevity. Upkeep with regular maintenance to hinder aquatic growth and algae blooms that can save on the budget for years in the future. #longtermerosioncontrol #doneright #donewell
