When Storm Surge Strikes: The Hidden Threat to Your Belmar Property’s Underground Sewer System

For coastal homeowners in Belmar, New Jersey, hurricanes and storm surges represent far more than just surface-level flooding concerns. While most property owners focus on protecting their roofs, windows, and above-ground structures, the combination of prolonged heavy rain and storm surges will likely back up your underground sewer lines. In addition, flooding can cause the lines to shift. Understanding how these powerful weather events impact your property’s underground infrastructure is crucial for protecting your home and maintaining its value.

The Vulnerability of Coastal Sewer Systems

Belmar’s location along the Jersey Shore makes it particularly susceptible to hurricane damage. “We’re not the biggest utility in the state, but pound for pound, South Monmouth was hit as hard by Superstorm Sandy as any utility in New Jersey,” says Michael Ruppel, executive director of the SMRSA. “Sandy not only tested our infrastructure, it tested every emergency response plan we’d been working on for 20 years or more.” This vulnerability extends to private sewer lines serving individual properties throughout the area.

The most common types of damage to buried wastewater and storm water infrastructure were the separation of pipe joints, leaks, and breaks. Much of the damage was attributed to ground subsidence and loss of bedding. Flooding caused supporting soils to become supersaturated, and then as floodwaters drained, the supporting soils began to shrink and subside. The movement of soils led to breaks and fractures in rigid pipe networks.

How Storm Surge Damages Underground Pipes

Storm surge creates multiple pathways for sewer line damage that many homeowners don’t anticipate. Solid debris such as twigs, dirt and rocks can get stuck in your underground sewer lines, blocking the flow of water and potentially causing lasting damage. Flooding can also cause sewer lines to shift around, preventing them from draining properly.

The pressure effects are equally concerning. Heavy rainfall flowing into your pipes raises the internal pressure, causing the pipes to crack and even burst. This internal pressure, combined with the external forces from saturated soil and shifting ground, creates a perfect storm for infrastructure failure.

Age plays a critical factor in vulnerability. The roots of growing trees can infiltrate the underground pipes, creating cracks and gaps that allow rainwater and sediment to seep in. It’s exacerbated with older clay or cast iron pipes—the standard before PVC plastic—which are more susceptible to cracking and corrosion. Other issues owe to natural wear and tear as old materials break down and the ground shifts and resettles. Across the Suncoast, hundreds of miles of clay pipes are now nearing a century old—well beyond the intended 50- to 60-year lifespan.

The Belmar Experience: Lessons from Superstorm Sandy

Superstorm Sandy provided a devastating case study for coastal sewer infrastructure damage in New Jersey. The highest water levels occurred north of the landfall point in Monmouth and Middlesex Counties, especially along the Raritan Bay, where the surge reached an estimated 4 to 9 ft (1.2 to 2.7 m). Along Sandy Hook at the northern end of Monmouth County, a tide gauge on a pier recorded a water level of 13.31 ft (4.06 m) above the average low tide, at which point the pier collapsed and the gauge stopped reporting. This indicated a storm surge of 8.57 ft (2.61 m), which broke the previous record high tide there by 2.87 ft (0.87 m), set by Hurricane Donna in 1960.

In New Jersey, 9 wastewater treatment plants were inoperable for a month. Many systems were sand-filled or corroded from salt water or damaged and not functioning as designed. These impacts cascaded down to individual property owners, many of whom experienced sewage backups and system failures that required extensive repairs.

Warning Signs of Sewer Line Damage

After a hurricane or major storm event, Belmar property owners should watch for several warning signs that indicate potential sewer line damage:

• Slow draining in multiple fixtures throughout the home
• Gurgling sounds from drains or toilets
• Sewage odors in the yard or basement
• Wet spots or lush patches of grass in the yard
• Sewage backups in lower-level drains

Blocked sewer lines can impact other appliances, including showers, toilets, dishwashers, sinks — basically anything that involves running water. In severe cases, it’s even possible for raw sewage backups to flow back into your home.

Professional Assessment and Repair Solutions

When storm damage is suspected, professional evaluation becomes essential. We video inspect your lines with a camera, then use high-pressure water jetting to remove any blockages. This technology allows technicians to identify the exact location and extent of damage without extensive excavation.
