Out here on the Texas Gulf Coast, a tropical storm or hurricane is not a matter of if. It is a matter of when. And when one tracks toward our 8-county footprint, the list of things to protect gets long fast. Your well and your septic system belong near the top of that list, because water problems after a storm can make a recovering property unlivable for days longer than the storm itself.
On well and septic before a hurricane, J4 Water Works starts with the same rule: diagnose first, then quote the work. See our emergency well and septic service for the urgent well, pump, and septic diagnosis behind this guide.
Here is what we do, and what we tell our customers to do, before the storm arrives, during the power outage, and once the skies clear.
Before the Storm: What to Do While You Still Have Time
Turn off the well pump at the breaker
If the forecast calls for flooding at your property, or if you are evacuating, turn off the well pump at the main breaker before you leave. A pump that runs while the well is flooded or while power surges can burn out the motor. Electrical surges during a storm are rough on pump motors and control boxes. If you have a surge protector on your electrical panel, make sure it is in place before storm season, not during a watch.
If you have a generator and plan to stay, check our generator backup for your well pump to confirm your generator can handle the pump motor startup load. Undersizing the generator is one of the most common mistakes we see after storms. The pump motor needs more amperage to start than it does to run, and a generator that is too small for the startup load will either trip the circuit or damage the motor trying.
Fill water containers before the storm hits
Fill bathtubs, stockpots, and any clean containers you have before the storm arrives. If the pump goes down or the well gets contaminated after the storm, you will want clean water on hand for drinking and sanitation. Do this the day before landfall, while the water is still clean and the pressure is still good.
Protect the wellhead if flooding is likely
The wellhead is the metal cap that sticks out of the ground over your well casing. If storm surge or sheet flooding is expected to reach it, that cap needs to be intact and secure. Check it before the storm. A cracked or loose wellhead cap is an opening for floodwater and contaminated surface runoff to enter your well. If yours is compromised, call us before the storm arrives. Fixing a wellhead cap is a short task. Treating a contaminated well after a flood takes days.
Aerobic septic: check tanks and alarms before the storm
If you have an aerobic septic system, make sure the control panel is working and the alarm float is set correctly before the storm. When power goes out, the aerobic pump stops. The system will not treat wastewater without power. That means what goes in during an outage sits untreated. The less you put into the system during an outage, the better. We cover the specifics of what each aerobic alarm means and what to do in our aerobic septic system alarms.
During the Storm: Keep Water Use Light
If you are staying through the storm and the well pump is still running, conserve water. The less you run through the septic system during a flooding or power-outage period, the less risk of backing things up. Avoid running the dishwasher or the washing machine, and skip the long showers during the storm itself. Flush toilets only when necessary.
For aerobic systems: if the power goes out, stop putting anything into the system that does not have to go in. Do not run laundry or the dishwasher. Use the toilets as needed but keep it minimal. The aerobic system is not treating anything without power, and every gallon you add goes into a system that is not working as designed. When power restores, the system will catch up, but give it time before returning to normal use.
After the Storm: Before You Drink the Water
Wait and test before you trust the well
This is the most important step after a storm. If floodwater reached your wellhead, or if you are not certain it did not, do not drink the water until it has been tested. Surface runoff picks up everything it passes over, including animal waste, agricultural chemicals, and fuel. Any of that can enter a compromised wellhead. The water may look clear and smell fine. Clear does not mean safe.
Read our your well after a flood or heavy rain for the full picture on what to check, when to wait, and when to test. If there is any chance floodwater reached the wellhead, treat the well before you drink. Our shock chlorinating your well walks through that process step by step.
Signs the well was compromised
The clearest signs are water that is cloudy or turbid right after the storm, water that smells different than before, and water with an unfamiliar taste. Any of those is reason to stop drinking it and get it tested. Also check the wellhead cap itself. If it is ajar, cracked, or missing, surface water got in. That well needs treatment before use, regardless of what the water looks like.
Septic inspection after a flood
Floodwater that saturates the drain field can temporarily overload the septic system. After a storm with significant rainfall, give the field a few days to drain and the soil to settle before resuming normal water use. If the system backs up or you see sewage surfacing near the drain field after the storm, call us. We will come out and assess whether the field is overwhelmed and temporarily saturated or whether something structural was damaged by the water or debris.
For aerobic systems, once power is restored, run the system through a full cycle and check that all the sprinkler heads and the alarm system are working correctly. Storm debris can clog spray heads. We see that on service calls consistently after tropical events across our footprint.
When to Call Versus When to Wait
After a storm, the urge to get everything running immediately is natural. Before you assume something is broken, give the soil and the system a chance to recover. Flooding saturates the ground. The drain field that looked overwhelmed on day one often drains and settles by day three. The aerobic spray heads that seemed dead may clear once you check them for debris.
The right time to call is when the system is not recovering after a reasonable wait, when you see sewage surfacing near the drain field, when the water still looks or smells off after you have waited and tested, or when the pump is not coming back on after power is restored. After a major storm we expect those calls, and we will be ready for them.
Building Rural Property That Handles Storms Better
If you are new to rural Texas property or planning a build, wellhead placement and height matter more than most people realize before their first tropical season. We plan wells to stay above likely flood levels where the land allows it. We build the wellhead correctly so it seals. We locate the septic field on ground that drains well and stays above the water table even in a saturated soil event.
Done right, a well and septic system on the Texas Gulf Coast can handle the weather this region throws at it, year after year. That means doing it right the first time. We treat your land like it's our own, which means planning for the storm season you will face out here, not the sunny day you are having when we break ground. If you are getting ready for storm season or dealing with the aftermath of a tropical storm and are not sure whether your well or septic is safe to use, call us. We will come out, look at it, and give you the honest answer. Done right beats done fast. That is especially true when the stakes are the water your family is drinking the week after a storm comes through.
