Rainwater drainage

I am experiencing flooding on my back patio. I have several solutions in place but the way my yard is set up - it continues to flood. I have installed a drain w/grate that drains to the front right side of my house. I have my gutter going to an underground pipe and flowing to the front left side of my house. But, I am on a cul-de-sac and have a pie shaped lot - with the back patio having a short backyard and level with the slab of the house. The person who installed my other fixes - says he's at a standstill because there is not enough slope to eliminate this water.

My question is - is there a "dirty water" sump pump that I could install myself that could be placed in a grate like drain - maybe battery run? Is this plausible or should I just call someone to install a pump? Thanks!

You can try regarding. Pictures would be nice so we could get a better understanding of your situation.

Really need that picture.
A slab at the same level as the house slab is never ever going to be a good thing.

Thanks for answering - The first picture shows before I added the sidewalk - I thought it would help, not so much. But there is no way I can regrade - there is a sidewalk on one side that leads to the pool and there is no way I am going to divert water there. I can't grade it towards the back because there is a house behind me and I am sure they are having similar problems. The other side of the house is higher and grading it would cause the person on that side to flood. And because I am at the back of the cul de sac, street water flows my way. Would a sump pump help?

A sump pump will not work unless it can send the water someplace else.

You may want to put a subtle berm at the front of your property so street water does not enter. The part put on your driveway would resemble a narrow "speed hump".

Where is water supposed to flow? Was there an intended swale through various neighboring lots ending up at the street somewhere else? Is there supposed to be a swale all around the cul de sac and continuing down the street where a sidewalk might ordinarily go?
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
