"I have 3 comments on the design of the unit: 1 The pump is difficult to locate without a cover over the conical hole in the lower basin. A non-corroding metal plate or concrete plug with slot for cable should be provided. 2 There is no specific provision for entry of water to the interior of the upper pedestal if the tapered concrete wall plug is fitted. There should preferably be some slots in the bottom of the pedestal or the pedestal has to be raised on the wedges provided (but not for this purpose). 3 Finally a spray/distributor would improve the flow discharge and would be inexpensive to provide."
