You're talking about the pressure relief on the top of the tubes, yeah the water being discharged looked very silty still, but it's always going to look that way because it's coming out of a bag full of silt ~ rofl. They need to keep working on the leaching process for the settling ponds, it's not that hard but it is extremely site specific. They need to install multiple layers of drainage materials, stone and filter fabric, etc... and then store the filtered water subsurface for reuse. There are many ways to do this, they just need to find the system that suits their site.
