Water & Waste Support
Fresh water supply and waste management for office trailer sites without plumbing infrastructure. Insulated, heated, enclosed boxes with built-in pumps — placed by forklift, serviced weekly.
Most job sites don't have water or sewer hookups. That means your office trailer's sinks, toilets, and showers won't work without external support. Our Water Box, Waste Box, and Complete Box give you self-contained water supply and waste holding inside an insulated, heated box — delivered to your site, connected to your trailer, and serviced weekly.
660 Gal Fresh Water Box
660 gallons of fresh water inside an insulated, heated, lockable box with a built-in pump and pressure tank. Set next to your office trailer by forklift and connected with a heated hose — running water without a city water hookup, year-round.
Best for: Sites without city water hookup
660 Gal Waste Waste Box
660 gallons of waste holding inside an insulated, heated, lockable box. Dual sewage pumps lift waste from your office trailer into the tanks, with high-level alarms before anything overflows. Pumped out on a weekly service route.
Best for: Sites without sewer hookup, high-traffic sites
Water + Waste Complete Box
270 gallons of fresh water and 330 gallons of waste holding in one insulated, heated, lockable box. Built-in water pump and sewage pump. One box, one forklift pick, one weekly service visit — no site plumbing hookups.
Best for: Sites with no water and no sewer
How It Works
Tanks, pumps, and a heater inside one insulated box next to your trailer. Water out through a heated hose, waste back through an insulated line, serviced weekly from outside ports.
- 1 Fresh water tank. Stored inside the insulated, heated box — not in an open tote in the weather.
- 2 Water pump + pressure tank. Built-in 12V pump and pressure tank push water through a heated hose to the trailer. Sinks and toilets work like they are on city water.
- 3 Waste line. The trailer drain runs to the box through a 3-inch line, sloped 1/4 inch per foot, wrapped in heat cable and insulation for winter.
- 4 Sump basin + sewage pump. Waste enters a sump basin inside the box. A sewage pump lifts it through a check valve into the waste tank. High-level alarms warn before anything backs up.
- 5 Waste tank. Sealed and vented inside the box. Out of sight, locked, and above freezing.
- 6 1,000W heater. Electric heater keeps the inside of the box above freezing. Runs on one dedicated 120V / 20A circuit along with the pumps.
- 7 Service ports. Our truck refills water through a 1-inch cam lock fill port and pumps waste through a 2-inch cam lock drain — same side of the box, one visit.
Daisy-Chain for Extended Capacity
Water Boxes and Waste Boxes are purpose-built to link together. Up to 3 boxes work as one system: 1,980 gallons of fresh water that can feed several trailers at once, or 1,980 gallons of waste holding, three times a single box.
Up to 3 boxes act as one 1,980-gallon supply. One box can feed several trailers at once.
- Two pump types and a 20-gallon pressure tank in each box: a high-flow pump (~20 GPM) moves a lot of water fast, and demand pumping holds steady pressure at the fixtures.
- Feeds several restroom or shower trailers continuously from one connection point. Rated to run two 8-stall shower trailers at once.
- Moves 100 gallons in about 10 minutes, so it also works as a fast-fill station for trailer tanks.
Up to 3 boxes act as one 1,980-gallon holding system. Three times the waste between pump-outs.
- Dual sewage pumps in each box. The second pump takes over automatically.
- High-level alarms in the sump basins and the tanks warn before anything backs up.
- Three boxes manage three times the waste of one, for large crews, multiple trailers, or longer stretches between pump-outs.
