imd59, I had a similar problem with sand entering the pond with the heavy downpours we have here in E Texas the past couple of year. So I rented a nice sized track hoe and built the sediment pond myself. Cost was around 2200, I had it for about 3 weeks, billing, went on hr used for a 40 hr work week. My point is, I am no heavy equipment guy but I got it done, and it catches most all of the sand and I now raise fathead minnows in it. Win, Win, I built in an overflow that runs into the big pond, after the sand settles out. I may get by with cleaning all the sand out every 3 or 4 years. Hope this helps.

PS, I don't think the cost of rental for clean out will come anywhere near the first time rental
