How fast can you deliver during a storm response?
Charleston sits low, and a heavy rain event or a named storm can knock out sewer service to a block or a whole neighborhood in an hour. Charleston Porta Pros treats disaster calls as priority dispatch, ahead of standing rental orders, because a shelter or a command post without a working restroom is a public health problem, not an inconvenience. Delivery windows shrink or stretch with road conditions. If Charleston is under a flood advisory, some routes get rerouted around standing water, and that changes drive time more than distance does. A crew based near the peninsula can usually reach James Island in under 20 minutes under clear roads, since it sits about 9.7 miles south, and Hanahan at 9.5 miles north runs similar. Goose Creek, 14.1 miles north, and Summerville, 22.3 miles northwest, take longer, especially if arterial roads are compromised. We stock standard units, ADA accessible units, and handwashing stations for immediate deployment, and we can add restroom trailers once a site stabilizes. For agencies needing a placement plan before trucks roll, our porta potty placement guide covers ground conditions and access routes.
What sanitation do shelters and command posts actually need?
A shelter needs toilets, handwashing, and enough of both to keep pace with population, not just a delivery truck showing up once. OSHA 1926.51(c) sets a baseline ratio of one toilet facility per 20 people, and that number is a reasonable planning floor for temporary shelter population even outside a jobsite context. Handwashing matters just as much: 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device, not hand sanitizer alone, so a portable sink rental or handwashing station rental belongs next to every cluster of toilets, not in a separate corner of the lot. Command posts and staging areas run leaner but still need potable water on site under OSHA 1926.51(a)(1). We size a shelter deployment by expected headcount, not floor space, and a fast intake call gets units moving before the exact count is finalized. Where a cluster of single-user toilets goes in for public use, ADA Standards section 213.2 requires at least 5 percent of the units be accessible, never fewer than one, so a mixed order of standard units and ADA accessible units is standard practice, not an add-on. Large-scale relief sites sometimes need a full restroom trailer once power and water are stabilized, including 4 stall or 8 stall configurations for higher traffic.
Do you handle septic and holding tank overflow after flooding?
Yes, and it's often the first call after the toilets. Flooding pushes groundwater into septic systems and can back up a tank that was working fine the week before; a typical residential tank runs 1,000 gallons and gets pumped every 3 to 5 years under normal use, but a flood event can force an emergency pump-out on any schedule. Charleston Porta Pros runs emergency septic service alongside disaster restroom deployment, and a holding tank rental can bridge a property while a damaged septic system gets inspected and repaired. Restaurants and shelters running temporary kitchens need grease management too; a grease interceptor is typically serviced once fats, oils, grease and solids reach 25 percent of the liquid depth, and our grease trap pumping crews handle that on the same dispatch cycle as toilets and holding tanks. Debris from storm cleanup needs somewhere to go, and a roll-off dumpster rental staged early keeps a relief site from turning into its own hazard. For sites needing to secure a perimeter around debris piles or damaged structures, temporary fence rental and crowd control barrier rental go out on the same trucks.
Frequently Asked Questions
Can you deploy without a signed contract during an emergency?
Yes, Charleston Porta Pros can move on a verbal authorization from an agency or property manager during active disaster response, with paperwork following delivery. Call our contact line or submit a quote request and we start routing trucks the same day where road access allows.
How many toilets does a 200-person shelter need?
Using the OSHA 1926.51(c) ratio of one facility per 20 people as a planning baseline, a 200-person shelter needs roughly ten units, plus at least one ADA accessible unit under ADA Standards 213.2. Our how many porta potties guide walks through the math for mixed populations.
Do you provide power for light towers or command trailers?
We stock light tower rental and can coordinate a temporary power pole for command post setups needing sustained power beyond generator run time. Ask when you request a quote so we route the right equipment on the first trip.
What if our site has no clean water access?
We bring water with the units. Handwashing stations arrive with their own reservoirs, satisfying OSHA 1926.51(a)(1)'s potable water requirement independent of site utilities. A portable sink rental works the same way for kitchens or medical triage tents.
Can you service storage or mobile office needs for relief staff?
Yes. A storage container rental or mobile office trailer rental can house supplies or staff operations near the restroom cluster, and both deliver on the same schedule as your sanitation order from Charleston Porta Pros.
