18 people drowned in Delaware in the 1913 flood. Today the Olentangy still threatens. Integrity Water Damage Restoration Ohio offers 24/7 water damage restoration. Call (614) 956-3233.
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.
01A City the River Has Already Taken — and a Reservoir Built Because of It
In March 1913, the Olentangy River rose through Delaware and killed 18 people (Beacon Journal) — part of the Great Flood that remains Ohio's deadliest weather disaster. Delaware's loss in 1913 was severe enough that the response became infrastructure: Delaware Reservoir, upstream on the Olentangy, provides flood control for the city below (USGS). Every flood-control decision in this watershed traces back to what the river did here.

That history isn't trivia. Delaware is a growing suburb with a historic downtown, and growth on a river plain always increases exposure: more impervious surface, more basements, more plumbing pushing through the same river corridor. The Olentangy still flows through the city — and while the reservoir blunts the river's worst surges, it does nothing for flash flooding on tributaries, storm-sewer overload, sewer backups, or the burst pipes and sump failures that cause most Delaware water-damage calls.
Integrity Water Damage Restoration Ohio provides 24/7 emergency water damage restoration across Delaware: extraction, structural drying, sewage cleanup, and mold prevention. Call (614) 956-3233.
02The Olentangy Today: Managed, Not Tamed
Delaware Reservoir upstream gives the city real protection against a repeat of 1913-scale river flooding. But reservoirs manage river flooding — the slow-rise, gauge-watched kind. They don't stop:

- Flash floods on tributary creeks and in low-lying neighborhoods during summer cloudbursts.
- Storm-sewer overload when inches fall in hours and streets become channels.
- Sewer backup when aging collection infrastructure surcharges.
- Basement seepage as saturated ground pushes water through foundation joints.
If your home sits anywhere near the Olentangy corridor or one of its tributary valleys, know your elevation relative to the floodplain — and know that finished basements below grade are the first thing the water finds. When water comes in, call (614) 956-3233 for immediate extraction and verified drying.
03Basement Flooding in Historic Downtown and New Subdivisions
Delaware's housing tells two flood stories. The historic downtown and its 19th- and early-20th-century homes have stone and block foundations, aging sewer laterals with root intrusion, and plumbing well past its expected lifespan — classic seepage and backup territory. The new growth-era subdivisions bring basement foundations on clay soils and total sump-pump dependence: when the pump dies or the power fails mid-storm, the basement fills from the bottom up.

Either way, the first 24–48 hours decide everything. Mold can begin within 24–48 hours of water exposure, per widely cited EPA guidance — which is why emergency extraction and professional drying on day one matters more than any other step. Integrity Water Damage Restoration Ohio maps moisture with meters and thermal imaging, dries to verified targets, and documents everything for your insurance claim. Call (614) 956-3233 24/7.
04Frozen Pipes and Sump Failures: Delaware's Winter and Summer Hazards
Central Ohio winters deliver freeze–thaw cycles that burst pipes in uninsulated crawlspaces and exterior walls — and Delaware's older homes are the most exposed. A single burst pipe can release hundreds of gallons before anyone's home to shut it off.

Summer is the mirror image: cloudbursts overwhelm sump systems, and power outages kill the pumps exactly when they're needed. If your sump pump is more than a few years old and has no battery backup, assume it will fail during the storm — and call (614) 956-3233 at the first sign of water.
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.

The river's catastrophic potential is real — 18 people drowned here in 1913, and Delaware Reservoir upstream was built to control Olentangy flooding. The reservoir manages river rises, but it doesn't prevent flash floods, storm-sewer overload, or sewer backups. If you're near the river corridor, know your floodplain status and keep a plan for basement water.
We do — most of our Delaware calls are stormwater seepage, sump-pump failure, and sewer backup, not river flooding. Call (614) 956-3233 24/7 for emergency extraction.
Standard policies typically exclude both: sewer backup needs a water backup endorsement, and rising river or creek water needs a separate NFIP flood policy. Photograph everything before cleanup and call us at (614) 956-3233 for claim-ready documentation.
Yes — it's Category 3 black water carrying bacteria and viruses. It requires professional extraction, contaminated-material removal, and disinfection. Stay out and call (614) 956-3233.
