Where a Wheaton Sump Pump Has to Discharge
Wheaton’s sump rule for new work is in Sec. 22-7 of the city’s building-code amendments, read on October 15, 2026. It is not Carol Stream’s 10-foot discharge note, and it is not Carol Stream’s Type C fee. A sump is also not the overhead sanitary ejector in the same section.
Footing tile, a pit, and a check valve
Sec. 22-7(b) requires an overhead storm sewer, which the heading calls sump pumps, for all new structures and for new additions to existing structures that have foundation footing tile drains. The footing tile connects by gravity to a sump pit with a pump. A back-flow check valve goes in the discharge line. The discharge line is a minimum of 1.5 inches. Every sump pit has a cover.
The discharge leaves through an exterior wall and ends no less than 18 inches beyond that wall. That 18-inch stub is the exit from the house. It is not a rule about how far the water then travels across the yard. A flooding-tips page that is sometimes summarized with a longer yard distance was not the document opened for this guide, so that distance is not stated here.
Storm sewer, or a dry well if none is available
When the overhead storm sewer is required under 22-7(b)(1), the discharge goes into a storm sewer service line, then a private storm sewer service, then a city storm sewer. If a city storm sewer is not available, the section allows a dry well or a stormwater practice approved by the director of engineering.
Available, in this section, means a city storm sewer in the city right-of-way adjacent to the property, or in an easement on or immediately adjacent to the property. A sewer across the neighborhood that does not touch the lot is not that definition. Ordinances O-2020-05, passed February 3, 2020, and O-2022-30, passed July 5, 2022, are the notes on the section.
The sanitary ejector is a different pipe
Sec. 22-7(a) is the overhead sanitary sewer. It applies to new structures, to additions that expand the lowest level, and to new basement remodeling, where the lowest level has or must have sanitary fixtures or drains. Fixtures drain to an ejection pit. The discharge line is a minimum of 2 inches and has both a check valve and a gate valve. Plumbing above that lowest level drains by gravity and does not go through the pit.
That ejector is sewage. The sump in subsection (b) is footing water. Connecting one to the other is the mistake Sec. 74-55 is written to stop. Sec. 74-55, Prohibited connections/infiltration, says it is unlawful to introduce stormwater, surface or roof runoff, or groundwater into the sanitary sewer. The library page that contains 74-55 also shows Sec. 74-108, which is a funds section. Do not cite 74-108 for this ban.
What this page does not borrow
Carol Stream’s village news says discharge stays at least 10 feet from the foundation and off the sidewalk and the street. That sentence is Carol Stream’s. Wheaton’s new-work rule, for houses that have footing tile, is the storm-sewer connection or the approved dry well. Glen Ellyn’s sidewalk rule is on the Glen Ellyn sump page.
A sump pump estimate should say whether the house is new work under 22-7 or an existing pit the section does not rewrite. Drain tile is the footing line that 22-7 connects to the pit. The flooding guide stays Carol Stream’s history. Glendale Heights, Bloomingdale, West Chicago, Winfield, and Hanover Park do not have sump pages, because their discharge rules were not read from a code or a city amendment for this update.

FAQ
Where does a new Wheaton sump discharge?
Sec. 22-7(b) sends footing-tile water to a sump with a pump, a check valve, a cover, and a discharge line of at least 1.5 inches that exits at least 18 inches beyond the exterior wall. When that overhead storm sewer is required, the water goes to a city storm sewer if one is available beside the property. If it is not, the section allows a dry well or a practice the director of engineering approves.
Can the sump tie into the sanitary sewer?
No. Sec. 74-55 makes it unlawful to introduce stormwater, surface or roof runoff, or groundwater into the sanitary sewer. The overhead sanitary ejector in Sec. 22-7(a) is a different system, with a 2-inch line, for sewage from the lowest level.
Does Sec. 22-7 cover every existing house?
The sump subsection is written for all new structures and for new additions to existing structures that have foundation footing tile drains. It does not, in the text that was read, rewrite every existing pit. Ask Wheaton before you treat an older house as exempt or as covered.
Is this Carol Stream’s 10-foot rule?
No. Carol Stream’s 10-foot note and Carol Stream’s Type C fee are that village’s. Wheaton’s new-work discharge rule is Sec. 22-7. This page does not print a Wheaton permit amount.
