Elgin: dry the candy room without cooking the sewer
You want the confectionery pack room dry enough that sugar stays free-flowing, and the coil is throwing warm water at a sewer. Elgin has not adopted a cleanroom humidity number, and nobody at the city has published 35 percent RH as a candy rule. The local sentence that changes this job is heat.
Fox River Water Reclamation District Ordinance 896, section 300.003.C.10, bars heat that inhibits biological activity at the treatment plant, and in no case heat that lets the temperature at the POTW treatment plant exceed 40°C (104°F), unless the approval authority allows another limit. That reading is taken at the plant. It is not a thermometer screwed into your condensate pan. We read the ordinance on October 8, 2026.
If you are Lena, running hard candy on the east side of downtown, the combined-sewer note matters more than a vendor’s RH slide. The district says the central area of the City of Elgin still uses combined sewers, so grease or a hot wash that misses pretreatment can reach the Fox River in a storm. South Elgin sits in the same district and the same ordinance. It does not get a looser 104°F line. What it does not share is that combined-sewer sentence.
- Do not hunt for an Elgin confectionery humidity ordinance. It is not there. The candy’s RH target is your product spec.
- 104°F is the treatment-plant ceiling in Ordinance 896, not a drain-pipe permit stamped on the air handler.
- A town page exists here because central Elgin’s combined sewers change where a missed condensate slug can go. South Elgin does not get that sentence.
| Role | What they sign or decide | What the document does not say |
|---|---|---|
| User discharging to the POTW | Must meet section 300.003, including the heat prohibition | No NEBB certificate is named |
| Property owner or authorized agent | Signs the connection-permit application | Does not set the candy room’s RH |
| Executive Director of the district | May authorize unpolluted water or impose mass limits | Does not publish a candy humidity table |
What the rule says here
Section 300.003.C of Ordinance 896 lists specific prohibitions for every user of the district POTW. Item 10 is the heat rule quoted above. Item 4 also blocks solid or viscous waste, including grease, that can obstruct a sewer. A sugary washdown is not “just water” if it carries product.
The district’s connection-permit page says commercial and industrial applications need a full plan set, separate from the set you give Elgin, and that review typically takes two to three weeks once the packet is complete. The property owner or an authorized agent signs. That clock is for a connection permit. The ordinance does not print a 14-business-day industrial-waste review. We will not invent one.
Federal food rules still sit on the room itself. A non-USDA confectionery line answers to 21 CFR 117.20: ventilation has to minimize vapors where they can contaminate food, and drip or condensate from ducts must not land on food or packaging. Drying the room and cooling the drain are two different jobs. Elgin’s sewer rule only governs the second one.
If you skip it
Skip the heat check and you can inhibit the treatment plant or, in a storm on the combined system, send a warm sugary slug toward the Fox River. The ordinance calls that interference or a pass-through problem. The city water department is not who wrote section 300.003. The district is.
Skip the humidity work for a different reason. If the pack room runs wet, sugar clumps and you scrap candy. That loss is yours. It is not a fine printed in Ordinance 896, and it is not a mold citation from a section the code does not contain. Do not let a contractor sell “Elgin mold compliance” off a humidity percentage the city never adopted.
How the next place differs
| Place | Heat rule | Combined sewer note |
|---|---|---|
| City of Elgin | Ordinance 896, 104°F at the treatment plant | District says the central area still has combined sewers |
| South Elgin | Same ordinance, same 104°F plant ceiling | Not the subject of that combined-sewer sentence |
| Elk Grove Village | MWRD limit is 150°F at the sewer entrance | Different district, different measuring point |
Checklist for this job
Write the peak condensate temperature at the drain, and say whether that water can reach a combined sewer.
Confirm the plant is inside the Fox River Water Reclamation District, not a different sanitary system.
Keep product RH on the candy spec sheet. Do not cite a city percentage you cannot find.
If you are adding a connection, budget two to three weeks of district review after the plan set is complete.
Check 21 CFR 117.20 separately so ceiling drip is not treated as a sewer question.
Read the Elk Grove note only if someone quotes 150°F. That number is a different pipe.
Fee or timeline in the document
Ordinance 896 does not print a confectionery humidity fee, a condensate permit fee, or a 14-day review. The document is silent on those dollars. The only timeline we can cite is the district’s own line: connection-permit review typically takes two to three weeks once the information is in.
Service fees for connections live in the district’s fee ordinances, which the permit page points you to. We are not copying a dollar figure we did not read on a fee table. Ask the district for the current connection fee before you put it in a budget. The diagnostic of the room is a separate purchase, described on the rule page, and it is not a city fee.
Questions people type
There isn’t one in the municipal code or in Ordinance 896. Humidity is whatever your candy needs so it doesn’t cake. The city rule that touches the air handler is the heat you may send toward the treatment plant, capped so the plant itself stays at or below 104°F unless an alternate limit is approved.
You dehumidify to the product spec and you keep condensate off the ceiling under 21 CFR 117.20. Elgin does not hand you the percentage. While you dry the room, measure the drain temperature so the water you pull out of the air does not become the heat problem in section 300.003.C.10.
We could not find a section 11.24.040 that sets a washdown temperature for confectionery coils. The enforceable heat language we did find is Ordinance 896, section 300.003.C.10, adopted by the Fox River Water Reclamation District. Use that document, not a guessed chapter number.
If the water never reaches the district sewer, the discharge prohibition does not apply to that loop. The moment you dump it, overflow it, or wash it down a floor drain, you are a user under the ordinance. Closed-loop recovery is a design choice. It is not a waiver printed in the ordinance.
