- Keeping water out of basements is a familiar subject, but I think this case
- is a challenge worth reading about. Specifically, it is...
-
- THE DUTCH CHALLENGE - LIVING BELOW THE WATER TABLE
-
- We have a 3 bedroom ranch with a full basement. It is in a formerly
- unincorporated area in the Chicago suburbs, and has a 3/4 acre yard.
- We are connected to city water, but have a septic field. Our lot is in
- the low part of a slightly sloping area of the houses immediately around us.
-
- The back 1/4 to 1/3 of our lot currently is flooded with 1 - 3 inches of
- water. Our septic field has flooded for short periods, but we have never had
- any apparent problems because of this.
-
- Currently our sump pump cycles every 90 seconds, with about 40 seconds of
- pumping time. The pump can move about ~37 gallons per minute out of our sump.
- Over the last few months the volume pumped has been from 20 to 30 gpm, or
- 1200 to 1800 gallons per hour; 28,000 - 43,200 gallons per day. If our
- basement filled at this rate (which it wouldn't of course), it would take
- only 1.5 days to fill it to ground level. This is equivalent to the volume
- of Lake Michigan over the time of our mortgage.
-
- Our sump pumps into a 6 inch line that drains to the far corner of our front
- yard, about 60 feet from our house. This is into a ditch that follows the
- lot line to the back. It has visible flow for about 150 feet, then seems
- stagnant.
-
- Other facts:
- There are NO broken water mains nearby.
- It is not unusual in our area to have sand or gravel seams underground.
- We have a battery backup pump, but it can't move enough water to keep up.
- The water in back is mainly from our neighbor(s). We're lower.
- It is a wet time of year, but not the wettest.
- There are storm sewers along the street, but only drain street level water.
- We plan to stay in the house for at least the next 3 years.
- I eventially plan to seek professional help - of one kind or another. :^)
-
-
- Here are some possibilities I have thought about.
-
- 1) Install a second pump in the same pit for safety and an electrical backup
- for power outages. Electrical backup could be batteries with conversion
- to house current, or an automatic generator of some kind. Pumps could
- alternate, or the new one could vary in speed with the water level.
- I don't know how to obtain some of these items. What setup is best?
-
- 2) After determining the pressure on the foundation this would represent,
- build a 1 - 2 foot wall around the sump pit and allow the water to come
- up higher. This would greatly increase the pump cycle time and might
- lower the total amount of water coming in because of the pressure. On
- the other hand, we would have some other seepage.
-
- 3) Try to map the underground water flow in our yard, using dye or such,
- with the goal of diverting or blocking the "underground river" somehow.
- Does anyone know how this is done and where to get the dye?
-
- 4) Call the city and neighbors and try to get some kind of property drainage
- system for our area. My concern here is the expense, waste of time
- with uncaring government, etc.
-
- 5) Covertly (ha!) dig next to the storm sewer, drill through the culvert
- and run my sump pump line into it. For that matter, I could pump my
- whole lot out. And plant tulips. And power it all with windmills.
- (You should see our electric bills. The lights dim when the pump goes on.)
-
- Any positive suggestions, ideas, etc. would be appreciated.
- Any negative suggestions, ideas, etc. are OK if they are funny but not rude.
