If your primary goal it to drain the water, then simply cutting a slot through the high spot can be quite effective.
Even though they are quite small (and as such will need cleaning somewhat more often than larger ones would) even an 1/8" wide cut made with a dry diamond blade will move water through a high spot (I've done that) to a sump/drain, and greatly reduce ponding/puddling in the basement. In my case I had a grinder, got a dry diamond blade for a tile job, and used it on the basement floor later.
If renting a tool for the job, a diamond bladed wet saw (preferably with a somewhat wider kerf) would be a better choice - but adding water to electrical tools not designed to have water spraying around is chancy at best, so I chose a dry type blade when purchasing one for my existing tool. Dust control is important for both your own health and the survival of your tool - it's best to have someone else holding a shop vacuum nozzle sucking up most of the dust before it can go anywhere, or lacking a helper, to attach the shop vacuum hose to your chosen tool somehow.
Aside comment - I found that painting the concrete also helped immensely with water movement/drainage - when the surface of the concrete is not acting like a sponge, the water is much more prone to just follow the drainage channels and leave. I chose white paint and the basement felt 3 times brighter as a result, too.
