I am an engineer for a public works department in a city government. We gladly accept the discharge from sump pumps, gutter downspouts, and yard drains into the city storm utility. That's what it's for, and pumping it anywhere else just floods your neighbor. Just don't pump your sump pump water into the sewer line, that pi$$es us off.
When you have a high water table and dig a big hole, you get a big pond. When you put a plastic tank in the big hole and pump the tank out, you get a dock. Given your basement and no grade for the lot, you have no choice but to pump this groundwater down to a level below the basement. You say you have an existing sump pump, well why not route all of your groundwater collection drains to that pump? That pump runs to the city system right? It must go somewhere. If the existing pump is at capacity or in a difficult location to add more lines, then you can certainly add a second, third, or fourth sump pump.
