Delete point features in point layer

I have to do a point deletion in a point layer. It's a layer with regular spreaded points containing current values. So, if there is no water there are no points, of course. I cannot select features by attribute (e.g. mod("fid",20) = 0 for each 20th point) because then i get an irregular point selection. If I try do create a buffer around each point, ArcGIS hangs because I have more than 1million points in the layer. I thought I could do it in the way I create a grid with a certain cell size and for all points which are within a cell I intersect the point which overlaps with the calculated centroid... Is that possible without complex scripting and does anyone have better and easier solutions??

Thanks for help
