When a water main breaks, every minute counts. Here's how the ELM Company's 24/7 emergency response protocol works — from first call to full restoration.
A water main break is not a maintenance issue. It is an emergency. The moment a main fails, the clock starts — on property damage, on service disruption, on liability, and on the cascading effects that a major water loss can have on a building or a neighborhood.
Property managers who have dealt with a water main emergency before know that the difference between a contained incident and a catastrophic loss often comes down to one thing: how fast the right contractor was on site.
Recognizing the Signs
Water main failures do not always announce themselves dramatically. A full-bore main break with water erupting from the street is unmistakable. But many failures begin more subtly: unexplained drops in water pressure, discolored water, wet spots appearing in basements or on pavement, sinkholes forming in parking lots or landscaped areas, or unusually high water bills that suggest a leak somewhere in the system.
If you observe any of these signs, treat them as an emergency until proven otherwise. A slow leak that goes unaddressed can become a catastrophic failure within hours, particularly in cold weather when freeze-thaw cycles accelerate pipe deterioration.
The First 15 Minutes
When a water main failure is confirmed or strongly suspected, the first priority is isolation. If the failure is on a private service line, locate and close the main shutoff valve for the property. If the failure is on a public main, contact the relevant municipal authority — in Boston, that is the Boston Water and Sewer Commission (BWSC) 24-hour emergency line at (617) 989-7000 — and simultaneously contact your emergency excavation contractor.
Do not wait for the municipal authority to respond before calling your contractor. Municipal response times vary, and the excavation work cannot begin until the contractor is on site. The two calls should happen simultaneously.
Document everything from the moment you identify the problem: photographs, timestamps, the names of everyone you speak with, and the actions taken. This documentation is essential for insurance claims and for understanding the scope of the repair.
What Happens When ELM Arrives
When ELM Company responds to a water main emergency, the first action on site is assessment and isolation — confirming the location and nature of the failure, establishing a safe work zone, and coordinating with the municipal authority on service isolation if the failure involves a public main.
Excavation begins as soon as the work zone is established. In urban environments with dense underground utilities, we use vacuum excavation to safely expose the failure area without risking damage to adjacent gas, electrical, or telecommunications infrastructure. Once the failure is exposed and the repair scope is confirmed, we execute the repair using commercial-grade materials and restore service.
Surface restoration — pavement patching, sidewalk repair, landscaping restoration — is the final step. We leave the site in pre-failure condition.
The Cost of Delay
The most expensive water main repairs are the ones where the failure was identified but the response was slow. Water intrusion into building foundations, electrical systems, and finished spaces compounds rapidly. Mold begins developing within 24–48 hours of water intrusion. Structural damage from saturated soils can take months to manifest but years to repair.
The cost of a rapid, professional emergency response is always less than the cost of the damage that accumulates while waiting for a slower one.
Preparing Before an Emergency Happens
The best time to identify your emergency excavation contractor is before you need one. Know who you will call, confirm they are licensed and insured for the work, and have their emergency contact information accessible to everyone on your team who might need it.
ELM Company offers complimentary critical infrastructure inspections for commercial and municipal clients — an on-site assessment of your water, sewer, and foundation infrastructure to identify risks before they become emergencies. Contact us to schedule yours.
