I have a shallow pan about 14" across. I got it at Home Depot, and it's used to put flower pots on as a water retainer.
Anyway, I fill it full of gravel and put a hose in it and somehow adjust it to drip about 10 drops a minute. The bees can crawl on the gravel, get water, and now drown.
Also, I put it about 100' from the hives. I had it close in, and they ignored it.
I don't use tap water, but I use water from a gutter rain barrel. I'm sure any water will do.
If you can get the pan to overflow onto some flat rocks, you might get some moss to grow and the bees love that.
