Water Emergency Right Now?
Do these five things first — then let us take it from there.
- Stay safe first. Don't walk through standing water if the power may be on — and never touch submerged outlets, panels, or appliances.
- Stop the source if you can. Shut the main water valve for a burst pipe or appliance leak. For storm flooding, focus on safety, not the water.
- Call (614) 956-3233 now. Our dispatchers answer 24/7 and can talk you through the next steps while a crew rolls.
- Move what matters. Lift rugs, electronics, and furniture legs out of the water if it's safe to do so — every inch helps.
- Don't wait on drying. Mold can start within 24–48 hours. Fast professional drying is the difference between a cleanup and a rebuild.
01The Largest Dry Dam in Ohio's Landmark Flood System — Just South of Town
Union (~6,859 residents, northern Montgomery County, ~15 miles northwest of Dayton) sits on the Stillwater River — and just south of town, on that same river at Englewood, stands the giant of Ohio flood control: the Englewood Dam, the largest of the Miami Conservancy District's five dry flood-control dams. The numbers are monumental: completed in December 1921, 110 feet high and 4,716 feet long, able to store 209,000 acre-feet of floodwater across 6,350 acres — with U.S. 40 carried across its top.
The MCD's five dry dams were built between 1919 and 1922 after the Great Flood of 1913 proved what the Great Miami watershed could do, and Englewood is the flagship. It exists for one purpose: to catch the Stillwater's flood pulses before they reach the Great Miami at Dayton. If your Union home or business takes on water — basement flooding, storm damage, burst pipes — Integrity Water Damage Restoration Ohio provides 24/7 emergency water damage restoration across Union and northern Montgomery County. Call (614) 956-3233.
022026: The Dam Is Up for Rehabilitation
Here's the development Union homeowners should know about: in September 2026, the Miami Conservancy District applied for FEMA hazard mitigation funding for an upstream-wall rehabilitation project covering the Englewood, Germantown, and Taylorsville dams — citing structural instabilities and deteriorated spillway concrete on the three Class I (high hazard) dams' primary spillways.
What this means, practically: the 105-year-old dam system protecting the corridor is aging, and its owner is now seeking federal money to rehabilitate it. That's responsible stewardship, not a crisis — but it underscores a point every Union homeowner should internalize. The dams manage river flood pulses. They do not stop flash flooding on local streams, storm-sewer overwhelm, sump pump failures, or burst pipes — the water damage that actually fills basements in Union. Your home's defenses (sump pump with battery backup, backwater valve, grading) are the flood control that protects your address, and no dam upstream changes that.
03The Stillwater: Scenic River, Real Flood History
The Stillwater River — 69 miles long, a tributary of the Great Miami — flows past Covington and Englewood (where the dam holds it) and southeast to join the Great Miami in Dayton. Its lowermost 58 miles were designated an Ohio State Scenic River in 1975, which speaks to its natural character. But scenic doesn't mean tame: the Stillwater was one of the Great Miami tributaries that flooded in the Great Flood of 1913, the catastrophe that created the entire MCD system.
For Union homeowners near the river corridor, the Stillwater is the flood exposure that matters most — spring rises, ice-jam complications in late winter, and the flash response of a 69-mile watershed when storms stall over Miami and Montgomery counties. Know your elevation relative to the river, keep flood insurance current if you're in the floodplain (standard homeowners policies exclude flooding), and at the first sign of water inside, call (614) 956-3233.
04September 2026: Union Named in a Flood Advisory
The most recent entry in Union's flood record is weeks old: on September 20, 2026, the National Weather Service issued a flood advisory naming Union, with 1–1.5 inches of rain producing minor flooding in low-lying and poor-drainage areas. It wasn't a catastrophe — it was the routine, recurring kind of Union water event: enough rain to find every low spot, every overwhelmed drain, every basement with a tired sump pump.
That's the pattern to plan for: not the 1913 deluge (the dams handle that), but the ordinary advisory-level events that arrive several times a year and do their damage one basement at a time.
More Than Water Removal
Water is only the first problem. Here's what we actually fix when we walk through your door.
Structural Damage
Standing water weakens framing, subfloors, and foundations. Fast extraction stops a small leak from becoming a structural repair.
Mold Growth
Mold can colonize damp drywall within 48 hours. We dry to verified moisture standards and treat surfaces to prevent regrowth.
Health Risks
Sewage backups and long-standing water carry bacteria and contaminants. We clean and sanitize until the space is safe again.
Lingering Odors
A musty smell means moisture is still hiding somewhere. We find the source, dry it completely, and deodorize — never just mask it.
Ruined Floors & Walls
Buckled hardwood, swollen drywall, peeling paint. We remove what can't be saved and rebuild what matters, start to finish.
Insurance Stress
Claims stall on thin documentation. We photograph everything, log moisture readings daily, and deliver adjuster-ready reports.
05Storm Country: The 2019 Tornado Path
Water damage in Union doesn't only come from rivers. On May 27, 2019, an EF4 tornado tore through Trotwood — immediately south of Union — in the Memorial Day outbreak that devastated the Dayton area. Tornadoes bring water damage in their wake: torn roofs admitting rain, shattered windows, and structural breaches that turn the next thunderstorm into an interior flood.
Union's growth-era subdivisions (the city incorporated in the early 1980s and grew steadily after) carry the standard newer-suburb water profile: grading and drainage that doesn't always perform as designed, sump pump dependence, and finished basements with high-value contents. Storm damage to roofs and siding is the other half of the equation — wind-driven rain finding every weakness the storm created.
Our process covers both: emergency board-up and roof tarping coordination, water extraction, moisture mapping with meters and thermal imaging, industrial drying verified by daily readings, sanitizing, mold prevention, and documented rebuild — with insurance-ready documentation formatted for adjusters. Call (614) 956-3233 24/7.

A dry dam holds back water only during floods and otherwise sits empty. Englewood Dam (completed December 1921; 110 feet high, 4,716 feet long) catches Stillwater River flood pulses upstream of Dayton, storing up to 209,000 acre-feet across 6,350 acres. It manages river flood pulses — not flash floods, storm-sewer backups, or burst pipes at your address.
The September 2026 FEMA funding application cites structural instabilities and deteriorated spillway concrete on the Englewood, Germantown, and Taylorsville dams' primary spillways — it's a rehabilitation project, not an emergency. Your practical takeaway: the system is aging, and your home-level defenses (sump pump, backwater valve, grading) matter regardless.
The Stillwater flooded in 1913 and remains Union's primary river-flood exposure — spring rises and flash responses to stalled storms. Check whether you're in the mapped floodplain, carry flood insurance if you are (standard homeowners policies exclude it), and call (614) 956-3233 at the first sign of water inside.
Typically, yes — wind and tornado damage (including rain entering through storm-created openings) is usually covered under standard homeowners policies, unlike river flooding or sewer backup. Document everything with photos before cleanup and call (614) 956-3233 for claim-ready documentation.
New-construction grading doesn't always perform as designed — soil settles, swales fill in, and the first big storms reveal the truth. Document the drainage defects with photos and dates, mitigate promptly, and call (614) 956-3233 for emergency extraction and drying.
