On-Site Hydration Services has spent years replacing bottled water at Vallejo job sites and events, and the trade is easy to explain. You stop buying pallets. You stop sending someone to the store before every shift, and you stop paying to haul bags of empty plastic off the site at the end of the week. One of our trailers holds 300 gallons of cold, filtered water, which works out to about 2,400 sixteen-ounce bottles you never have to buy, stack or throw away. The whole bottled water routine, from the order to the ice to the trash pickup, becomes one parked trailer that we keep full. Call us or get a free quote, and we will size it to your crew or your crowd.
One Signature trailer can pour for a weekend concert and be working a slab pour a couple of days later. Hiring one company for your events and a separate one for your worksites makes no sense. Either way, the planning, the delivery, and the refills are ours.
The onboard cooling unit keeps the tank genuinely cold all the way through a Vallejo afternoon, and that single detail carries the whole thing. Warm water is water people abandon, and midsummer is exactly when a crew or a crowd is drinking the most. Cold water gets finished, and finishing it is what keeps heat illness off the site.
Typical Vallejo deliveries land in about 45 minutes, and we keep emergency runs going around the clock whenever a heat advisory or a power shutoff hits the North Bay. The morning a foreman finds his 40-person crew stuck with one warm cooler, speed is the whole game.
One rule sits under every job we take: water that people walk past might as well not be there. We've stood on a bare Vallejo site and watched shrink-wrapped pallets cook next to the job-trailer while the crew baked thirty yards off. We've watched the opposite too, a chilled station ten steps off the work face run bone-dry twice inside one shift. Everything that matters lives in the distance between those two pictures. Which is why we don't drop a unit and disappear. We match it to your headcount or your gate count, set the refill rhythm to how hard you're really pulling on it, and treat a heat call the way you'd want your own treated, meaning right now, because out here one hot hour can swing the whole day.
Delivery timed around Route 37 and the ferry crowd. Route 37 floods, and downtown streets get tight when a ferry lets out. We plan each tow around both, so the trailer is in place before your people are.
“We had crews split between two buildings and the water was always at the wrong one. They parked the trailer between both and kept it full all month. My guys actually drink water now instead of waiting for lunch.”
“August practice used to mean coolers and bags of ice. The fill stations moved a whole team through in a couple of minutes.”
“They moved the trailer twice as we worked down the road. Never had a dry morning.”
Downtown's older street grid is narrow and parking is tight, so we plan the drop spot before we tow in. Most work here is recurring: the Saturday farmers market, the Second Friday Artwalk that has run monthly since 2014, and festivals on the waterfront green.
The island is its own world, reached over the causeway and past Dry Dock No. 1 and St. Peter's Chapel. Work here mixes redevelopment crews, campus events and large festivals on open shipyard ground with very little built-in water.
Glen Cove is mostly homes, a waterfront park and the marina along the strait. Calls here tend to be youth sports days and public park events that need one trailer for a few hours.
New home construction and hillside streets up north mean we check the grade and the turnaround room before we tow. Residential building crews here work the same heat as anywhere else, with fewer shade options.
This is where the biggest crowds gather, next to I-80 and Highway 37. The Solano County Fairgrounds books touring shows and markets, and Amtrak Thruway buses stop at Six Flags Discovery Kingdom, so foot traffic comes in waves.
Few projects put as many trades on one pad as a data center build, and few run as long. Our stations serve the North Bay sites with cold filtered water, ground protection where the site demands it, and a tanker schedule that follows the headcount as electricians and pipe crews stack up toward commissioning. Night pours and weekend shifts are covered too, because those campuses do not keep office hours.
Around Vallejo, that means the same trailer can sit on a Mare Island pad for a month or roll onto the Waterfront Green for one Saturday, with the same cold water at both.
With a frame, a hitch, and tires under it, the unit hauls out to a remote build in the North Bay, an event field, a working orchard, or a disaster staging yard with equal ease. Vallejo contractors and event planners request this exact rig by name. The whole design is built around backing in, leveling off, and pouring cold by the same afternoon.

A lot of the sports in Vallejo happen right next to the water. Cal Maritime fields 14 varsity teams on its campus along the Carquinez Strait, from rugby to crew, and the fall seasons at Vallejo High and Jesse M. Bethel High fill fields and tracks starting in August. Tournaments and meets at sites like these bring in visiting teams and parents, and everyone looks for water at the same break.
August practice is the hard one. Two-a-days start in the morning fog, but an offshore afternoon can push the field well past what the forecast said. We've learned to park the trailer where coaches can see it from the sideline. Breaks go faster. Nobody walks half a block for a refill.
Runs and races need a different setup. The Vallejo Run Club meets at the ferry terminal on Saturday mornings and Wednesday evenings, and any larger run along the waterfront needs a refill point near the finish, where the crowd bunches up. For a race we usually set the trailer just past the finish chute, with the jug fill facing the volunteer tent so they can refill coolers for the aid stations on the course.
Players bring their own bottles now, and four fill stations move a line quickly. We plan tournament weekends by the number of teams and games per field, not just the headcount at the gate. Send us your schedule, and we will map out where the water goes.
Six bottles per person on a 100-degree day in the North Bay, a 38-person crew, and you're already at roughly 228 plastic bottles to buy, cart in, ice down, and throw away. That's one day. The season is where it gets ugly.
Multiply across a 175-day build and the tally clears 39,000 bottles, with the larger commercial jobs running far past that. A single trailer makes the entire pile disappear, leaving cold water at the tap and nothing for the dumpster.
Sustainability is the easy part of the pitch. Roughly 60 million plastic bottles get thrown out daily in this country, only about a third are ever recycled, and one bottle can sit in a landfill for centuries. Worth reporting, sure. But the Vallejo project managers who actually switch usually do it to kill the daily hassle, not to pad a sustainability slide. A shared trailer means no recurring bottle order, no cooler going warm before first break, no wall of empty jugs baking by the job-trailer. The super runs the build, not the water program.
Because our own potable tankers cover the refills, the supply scales with the job rather than fighting it. Double the crew for a big pour and they still can't drink faster than the plan. And the tankers just swing back and bring the level up.
Want this math run for your own Vallejo job? Two minutes on the phone gets you a real number.
Events like Maker Faire Bay Area spread across the Historic Mare Island Shipyard and the promenade, with no public fountains built in. One trailer on the main walkway gives exhibitors and visitors a place to refill all weekend.
The Solano County Fairgrounds books long runs and weekend markets back to back. For a multi-week show we park once and refill on a set schedule until load-out.
A one-day festival on open parkland has no built-in water for guests. A bottle filling station near the main lawn entrance gives people a free refill point all day.
The downtown farmers market and the Second Friday Artwalk come back every week and every month. A standing booking keeps a trailer on the calendar without a new order each time.
A water source people don't trust gets ignored, and an ignored station is rented money wasted. That's why municipal water doesn't reach the tap raw on our trailers. It passes through three filter stages and a UV chamber, then an onboard cooling unit drops the temperature. The result tastes clean and comes out cold, even on the worst Vallejo afternoon of the year.
The opening filter traps sand, scale, and the fine grit local mains occasionally push through. On a dusty Vallejo lot, that's what keeps a pour from tasting like the parcel it's parked on.
Activated carbon comes next, lifting the chlorine bite and the dull seasonal notes local tap can carry until the taste lands clean and neutral. When it's 100 out, that flavor decides whether a crew keeps drinking or walks past the tap dry.
A finer cartridge then catches the microscopic particles that slip past the first two, so what reaches the spout is clear rather than merely cold for the crews and crowds across Vallejo.
The last step is an ultraviolet chamber that wipes out bacteria and microbes without adding a single chemical. Even after a long tow to the far edge of the North Bay, the water off the nozzle is clean.
Along the wall sit four adjustable push-back taps, press a bottle to the bar and it pours. One of them is set at ADA-reachable height, so a single trailer includes everybody at a Vallejo crew or crowd with no add-on gear. Out back, a large-jug spout services five-gallon coolers and hydration packs, while a bank of hose connection taps handles work-site chores, event support, and refills down the orchard rows. Stainless, food-grade plumbing the whole way through keeps the filtered, chilled water at quality right to the spout.
Every Signature trailer carries a 300-gallon load, roughly 2,400 cups at sixteen ounces each, and we recharge it on demand, so the unit doesn't turn into the choke point on a busy Vallejo shift or a packed show night.
There's nothing here for you to run. Placement, fresh-water load, hookup, that's all on us, and then we walk your Vallejo crew or event staff through the basics before our truck pulls away.
People count, number of days, where exactly it parks on your Vallejo site, and what power is there. Those four answers let us spec it correctly the first time around.
Reckon roughly 45 minutes from our yard to anywhere in Vallejo or the North Bay, with round-the-clock emergency runs whenever a heat advisory or a power shutoff hits the area.
Once on site we set it level, charge the 300-gallon tank, and tie in power off one to four standard 120V circuits, or a single 50-amp 240V drop, depending on what the site gives us.
After that the tankers cycle back on a cadence matched to how fast your crew or crowd pulls it down, and we maintain the unit through the whole rental term.
No power on the parcel at all? We price that in. The unit draws very little, and with the service fleet backing it we've run Vallejo stations on lots that had no permanent power whatsoever. Lay out what the site offers and the rest is on us.
California's outdoor heat rule, Title 8 Section 3395, covers every outdoor workplace in the state. Employers must provide drinking water that is fresh, pure, suitably cool and free, placed close to where people work, with enough on hand for one quart per worker per hour for the whole shift. Shade has to be up once it hits 80 degrees. At 95 degrees, construction, landscaping and a few other trades must also run high-heat steps like pre-shift meetings and regular water reminders.
The indoor rule, Section 3396, took effect July 23, 2024. It applies once an indoor work area reaches 82 degrees with staff inside, and the full list of steps kicks in at 87 degrees. The same quart per hour applies, and cool-down areas have to be kept close by. That reaches into warehouse buildings on Mare Island, semi-enclosed barns at the fairgrounds and any event tent that heats up with people working inside.
Locally, building and construction permits go through the City of Vallejo's Central Permit Center, and events on city property go through the city's special events process. Shows at the Solano County Fairgrounds work through the venue's own agreements, and any food or drink service at a market or festival typically goes through county environmental health. Our trailer gives you a clear, documented water source for each of those plans.
Need a station your written heat plan can point to? We can have one pouring cold within days.
Every the North Bay job is a little different, but most follow a few common patterns. Here is how a typical setup plays out:
A typical setup for a building rehab crew. A typical setup for a crew working a building rehab on Mare Island in the summer looks like this: the trailer sets up next to the break tent before the job starts, replacing a row of coolers that usually go warm by mid-morning. We schedule refills twice a week to match crew size and heat. Placement stays close enough that crews do not lose work time walking to it.
A typical setup for a two-day youth sports tournament. A typical setup for a weekend youth soccer tournament in Vallejo looks like this: the trailer arrives with a full tank and stays on the field for both days. If an offshore wind pushes the temperature up on the second day, we move the morning refill earlier to keep the tank cold through the afternoon games. Coaches and families fill up at the same station both days.
A typical setup for a campus event during a shutoff watch. A typical setup for a graduation or campus event during a PG&E shutoff watch looks like this: if the campus has backup power on one building, we tie the trailer into a dedicated circuit from that building and test it the day before the event. Families and staff fill bottles at the station through the morning. This keeps the event running on cold water even with the power grid at risk.
Vallejo City Unified has 10 elementary schools, 4 middle schools and 2 comprehensive high schools, plus alternative and adult programs. With that many buildings, some campus is almost always getting new roofs, new plumbing or a full rebuild, and summer break is when most of that work gets done.
Summer campus jobs bring two problems at once. The building water may be shut off while the plumbing is redone, and the crew is working through the warmest weeks of the year. A temporary station takes care of both. The crew has cold water without tapping a building that's torn open, and the ADA-accessible fill station means summer office staff can use it too.
Colleges add their own mix. Solano Community College opened its Vallejo campus in 2018, Touro University California has a health sciences campus on Mare Island, and Cal Maritime is right on the strait. Move-in days, orientation weekends and graduations put a lot of people outside for hours, often on a lawn with one drinking fountain for the whole crowd.
Timing matters on school jobs. We book district and college work around the school calendar: in before the crew starts in June, out before teachers come back. We send the insurance certificate and the cleaning record ahead of time, so facilities staff can file them with the job.
Everyone sees the trailer. What they don't see is the support fleet behind it, the trucks that deliver fresh water, hold reserve on site, and carry wastewater off, so a single call wraps the entire loop rather than stringing together three vendors.
Our tankers run drinking-grade water in bulk, recharging the 300-gallon tank on whatever interval the headcount demands. Those same trucks also top up storage tanks, holding tanks, and bladder bags whenever a single drop can't keep pace, like a big slab pour or a downtown night that packs the square.
When demand spikes we set out fold-flat bladders to bank extra fresh reserve, and on a drain-less lot they'll temporarily hold greywater too. It isn't fancy equipment, but it's what keeps a far-flung job in the North Bay pouring between tanker runs.
Water that has to move across a job is a pump truck's job, whether that's charging holding tanks or hauling supply end to end. It earns its keep on the sprawling parcels where the trailer and the fill point can end up a fair hike apart.
At the tail end, a vacuum truck draws off greywater and wastewater and carries it to permitted disposal, closing the loop clean. Nobody on your Vallejo crew is left guessing where the used water ended up. That piece was built into the plan from day one.
Every job gets its own setup. A remote parcel might run a station plus a bladder bag for reserve and a recurring water-truck schedule. A heavy event night might call for a pump truck to move supply and a teardown waste run at the end. Describe the shape of your job and we'll put together the right combination, on one invoice, handled by one crew that already knows the ground.
A couple of minutes on the phone is enough to get you a real number. Here's what we'll want to know, handy to have ready before you call, and proof that we size every job to the work in front of us rather than reading off one canned quote.
Bottled water reads as the budget choice on a purchase order. Its actual price tag is buried somewhere else, in handling hours, staging footprint, water that warms up, and trash piling up afterward, and on a hot inland lot each of those costs more than it would by the coast.
Look at everything bottled water actually demands of a person: cutting the order, receiving and breaking down pallets, icing coolers before dawn, topping them up through the day, then flattening empty bottles for the bin. On a large Vallejo crew that's hours of paid time burned every single day, scraped right off the work that's supposed to be getting done. The trailer erases that loop entirely. A local contractor once let us pencil it out with him, and the recovered labor by itself paid for the unit. His words were that the bottle runs had been quietly costing him close to a day of payroll a week. Our trailer arrives full, the tankers keep it full, and your superintendent owes it nothing but a parking spot.
Ice a cooler at 6 a.m. and by mid-morning in July around the North Bay it's as warm as a bath. Warm water is water people stop touching, and the slowdown that follows is precisely where heat illness gets its opening. A chilled station never rides that warm-up curve at all. Whatever pours at clock-out is as cold as the sunrise fill, which happens to be the moment a spent crew, or a crowd deep into a long concert, leans on it hardest.
Bottled-water pallets devour staging space, jam the lay-down area, and sit cooking in the sun until somebody finally cracks them open. Empties build up faster than anyone keeps up with, and on a tight commercial lot that pile turns into its own problem. Set a trailer in one parking stall instead and it serves a crew or crowd that would otherwise burn through hundreds of plastic bottles every day.
Every bottle bought is a bottle thrown out, and across a season a busy site or event generates a small mountain of them. That's a disposal line on the budget, a dent in the sustainability numbers, and, given that a single bottle can linger in the ground for centuries, a footprint that lasts longer than the project that made it. Move to a refill station and the line drops to zero, which finally gives your reporting a figure worth publishing.
We deliver from downtown and Mare Island out to Benicia, American Canyon and the Napa line, and our California filtered water station rentals cover the rest of the state when your work moves. Our service area reaches all 50 states, so the same trailer and the same standards can follow your crew.
Working a corridor instead of a single address? We follow the main routes across the North Bay, so multi-site projects get the same fast turnaround as one stop.
Still weighing it? Call and ask. Most of these questions get settled in one short conversation. See also: filtered water station rentals and refilled on schedule water stations in Antioch, California.
Yes. Long jobs are a big part of what we do, and we set them up by the week or the month. We put refills and sanitizing on a fixed schedule, so nobody on your crew has to track the tank. If the job moves across the island or the work zone shifts, we move the trailer with it.
Yes. Every trailer is sanitized before it leaves our yard, and on rentals longer than a couple of weeks we flush and sanitize on a set schedule. Filters get changed when they are due, not when they fail. We leave a service record after each visit so you have a paper trail if anyone asks.
Yes, and the math is simple. Plan on about a quart per worker per hour, so a 40-person crew on a 10-hour day needs around 100 gallons. Add more on offshore wind days, when the bay breeze quits and the afternoon runs far hotter than the forecast. One trailer covers that crew with room to spare, and we set the refill schedule so the tank never gets close to empty.
It is. The water passes through sediment, carbon and micro-particulate filters, and then a UV light step disinfects it before it reaches the nozzle. That takes out sediment, chlorine taste, odors and fine particles. We fill from potable sources, inspect the system at each service visit and record it in the service log.
Put it where the crew already walks, near the break area or the tool trailer, not out by the gate. The trailer is 12 feet 3 inches long and 7 feet 6 inches wide, so plan for a level spot a little bigger than that, plus room for our truck to back in. Keep it clear of crane swing paths and heavy equipment lanes. It also needs to be within reach of the power circuits it draws from.
The four stations are bottle fillers with push-back nozzles, so they work best when people bring a bottle or a cup. For crews that is easy, since most already carry one. For a public event, tell guests ahead of time to bring a bottle, and keep a stack of cups at the trailer for the people who forget. The rear jug fill is for coolers and big containers, not for drinking from directly.
Before the job starts, we can send the spec sheet, our insurance certificate and our SAM.gov details for public contracts. During the rental you get a service record for every refill and sanitizing visit. Those papers fit right into your written heat illness prevention plan. If a city, county or Cal/OSHA inspector walks the site, you can show where the water is and when it was serviced.
A few things drive the quote. Rental length is the biggest one, followed by how many trailers you need and how often we refill. Site access matters too, since a Mare Island drop with Route 37 detours takes more time than an open lot off I-80. Short-notice and emergency orders are handled on their own terms, so call us and we will walk you through it.
Usually, yes. The trailer weighs 3,100 pounds, so on soft grass we put down boards or mats under the tires and jacks to protect the turf. Check your park permit, because some permits limit where vehicles can drive on the lawn. We will walk the drop spot with your site plan before event day.
Three to four weeks is a good target for September and October weekends, when festivals, fairgrounds shows and school sports all stack up. Summer construction is steadier, but booking two weeks out still helps us plan refills. For emergencies, call anyway. We move trailers around to cover urgent needs when we can.
Yes, it needs power for the chiller and the pumps. It draws from 1 to 4 dedicated 20A/120V circuits or one 50A/240V circuit. During a shutoff it keeps working if your site has backup power on those circuits, so it's smart to pick that spot before fire season. The water in the tank is separate from city water, so a main break or low tap pressure does not affect it.
Yes. Benicia is a short drive east on I-780, and American Canyon and the Napa city line are just north on Highway 29. We run those deliveries on the same routes and the same refill schedule we use in Vallejo. The whole North Bay is close enough that one account covers jobs on both sides of the county line.
A one-day festival on the Barbara Kondylis Waterfront Green looks simple on paper. It's a lawn by the river, a stage, a row of vendor tents and a big crowd. The green is parkland, not a built festival ground, so there is no plan for drinking water beyond what vendors sell. That gap is where first-year events get into trouble, usually around 2 p.m., when drink lines get long and the free water runs out.
Start with two numbers: how many people you expect at the busiest hour, and how many hours the gates are open. For a crowd that is mostly walking around, we plan on a cup or two per person over a four to six hour event. Add more if there is dancing, a fun run or kids' games in the sun. One trailer covers most single-day crowds on the waterfront. If you expect a very large crowd spread across the whole green, plan on two and put them at opposite ends.
Touring shows and markets book the Solano County Fairgrounds for runs that last a weekend or stretch past a week. The Sheep Barn alone has held a circus engagement of more than a week and a two-day market in the same fall season. A long run changes how you plan water. You are not covering a crowd for one day. You are covering a crew that practically lives on the grounds, rehearses, sets up, tears down and does it again.
Split your planning into two groups. The crew works long days before the doors open and long nights after they close. Guests come for a few hours at a time. Crew water should sit close to the back-of-house area, where people actually spend their day. Guest water belongs near the entrance or the food line. On many long runs we park one trailer where the crew can reach it and use the rear jug fill to stock coolers for the guest side.
Jobs on Mare Island and along State Route 37 come with their own logistics. The island is reached over the causeway, and Route 37 sits close to sea level through the marsh. A levee break in February 2019 closed the westbound side for five days, and the road was shut for a total of 28 days in the winter of 2016 to 2017. Before you sign with any water vendor for work out here, ask a few plain questions.
First, how will they get to you when Route 37 is wet? A vendor who only knows the direct route will be late the first time the highway closes. We plan a backup route through downtown Vallejo and back across the causeway from the north side. On rainy weeks we move refill visits earlier in the day to leave time for detours.
Cal/OSHA Title 8 Section 3395, outdoor heat illness prevention
A fire does not have to start inside the city limits to reach Vallejo. The 2020 LNU Lightning Complex burned 363,220 acres across six counties, Solano County among them, and the 2017 Atlas Fire burned across both Napa and Solano counties. Fires that size fill the North Bay with smoke for days. People stay indoors, community rooms and gyms fill up, and suddenly one building is doing the job of a small shelter.
Power shutoffs are the other half of the picture. PG&E cuts power to lines in high wind and dry weather to prevent fires, and the October 2019 shutoffs reached about 30 Northern California counties and more than 3 million people at the peak. PG&E has since aimed to restore power within about 12 hours. Some water systems depend on electric pumps to hold pressure, so even a short outage can mean weak taps in parts of a service area.
Cal/OSHA Title 8 Section 3396, indoor heat illness prevention
Big crowds in Vallejo rarely arrive at a steady pace. Amtrak Thruway buses stop at Vallejo Station and at Six Flags Discovery Kingdom, ferries land downtown on a schedule, and a whole busload or boatload of people shows up at once. Waves like that create lines. A refill point for a big crowd has to be planned for the rush, not the average.
Four fill stations help, but only if people can reach all four. Set the trailer so the fill side faces the open walkway, not a wall or a tent. Leave about 15 feet of clear space in front so a line can form without blocking foot traffic. If the line has to bend, bend it along the trailer, not across the path.
“The insurance papers and cleaning record showed up before the trailer did, which made my week easier. Setup was quick and the unit was spotless.”
“We put it by the main lawn and the line never got long. Our vendors were glad guests stopped asking them for free cups of water.”
“Our heat plan says water close to the work, and this made that easy to show on a site walk. On a 96 degree day the cold water mattered more than I expected. Rebooked for the next phase.”
“Our aid station volunteers filled every cooler from the rear jug fill in about fifteen minutes. That used to take an hour at a hose.”
“Two weeks, one trailer, refills right on time. Our crew had cold water every show day and we never had to think about it.”
“Building water was off all summer. The trailer was our only drinking water on site and it never ran dry.”
“Parents noticed right away. Kids filled bottles between games instead of lining up at the snack stand.”
“Easy to book. They checked the slope on our lot before they came up, set it level on the first try and picked it up the Monday after we finished framing.”
“During a smoke week we had a room full of people and one small kitchen sink. They set the trailer up outside the side door the next morning, on the circuit our building had on backup power.”
Service information current as of September 2026.
Tell us the headcount or the gate count, the rental dates, and where the trailer should park, and we'll spec the right setup and roll one out to you anywhere in the North Bay, usually inside about 45 minutes of dispatch.
