Thread: Moving sump discharge from sidewalk to lawn?

  1. #1

    Default Moving sump discharge from sidewalk to lawn?

    Here's my saga in brief - this past fall, after having the basement flooded due to a frozen sump outlet, I rented a trencher and buried our discharge pipe. Due to the slope of the lawn and the proximity of the neighbor's house I ran the pipe across the lawn and out through a stone wall onto the sidewalk. All has been functioning well, but I just learned that having the sump discharge on to a city sidewalk is a violation and if seen could result in our water being shut off - yikes.

    So does anyone know of any products to help distribute the discharge over a lawn? Or, there's a bank on the side of the lawn sloping down to the neighbors - would a stone/gravel bank work without flooding the neighbor? Since we're in Boston, freezing is a huge factor and since it's the front lawn, appearance is as well. And to give you a sense of volume, after long term heavy rains the pump will put out 4-6 g/min for 3-4 days.

    Thanks for any insights...

    It would look a little funny in the winter, but that 4 - 6 gpm would run a couple of sprinklers.

    They may allow you to connect the outlet to the storm sewer lines (not the normal sewer lines). This usually requires a special licensed plumber to do. This may be the cleanest method.

    Discharging the water onto the sidewalk would create a skating rink in the winter, creating a pretty bad safety hazard. Hope you liability insurance is pretty hefty.

    Depending on the slope and shape of things, a drywell might work, but it could end up just causing you to pump the same water all over again.

    Another solution is a plane ticket to California and a good agent to sell your house. These sump pump questions are foreign to those parts of the world without basements and high groundwater. Consider a mountainous rural area in California if regulations are against your philosophy.

    The more I read here, the more I realize that many basements are an expensive luxury.

    I live on the top of a hill in California and I have standing water under my house for 6 months out of the year. It comes from an underground spring, not improper drainage. I am going to install a sump pump to pump it out.

    Lucky! But maybe you can save the trouble of a pump system...

    Trench it to daylight to save a pump.... Or construct a siphon to avoid a pump, if your property line allows you to get below basement level. You can even construct an automatic siphon that will turn itself off and on and never use a single watt.

    OR.... dig deeper - develop it, and use the water for the house supply
