What are mobile water provisioning systems used for?
Mobile water provisioning systems provide water storage and distribution capabilities where fixed infrastructure does not exist or has been destroyed. Applications include disaster relief operations supplying water to displaced populations, military forward operating base water supply, large outdoor events, and remote construction sites. Systems move water from a treatment source to end users efficiently and safely.
What sizes of water bladder tanks do you supply?
We supply collapsible water bladder tanks from 5,000 gallons up to 50,000 gallons. Smaller 5,000-10,000 gallon units can be transported on a pickup truck and deployed by two people in under an hour. Larger 50,000-gallon units arrive in a compact package that expands on site and can be operational within a day. All tanks use NSF-approved materials for potable water contact.
How does a tanker truck fill station work?
A fill station consists of a metered, quick-connect outlet plumbed to a treated water source, with flow control valves and optional metering for water accounting. Tanker trucks connect via standard cam-lock or fire hose fittings, fill at rates of 100-500 GPM depending on pump capacity, then distribute water to storage points or directly to populations. Fill stations can serve multiple trucks simultaneously with manifolded outlets.
How is water quality maintained in bladder tank storage?
Maintaining water quality in storage requires an adequate disinfection residual (0.2-0.5 mg/L free chlorine for potable water) at the time of storage. Bladder tanks use UV-resistant materials and are fully covered to prevent algae growth and contamination. For extended storage beyond 24-48 hours, re-chlorination at the point of distribution is recommended. Tank materials are tested to prevent leaching into stored water.
Can gravity-fed distribution systems reach end users without pumps?
Gravity distribution works when the storage bladder or tank can be positioned at an elevation at least 30-50 feet above the distribution point, providing 13-22 PSI working pressure. On flat terrain, a small booster pump is required. Gravity systems are preferred for their simplicity and freedom from fuel dependence in prolonged operations. We design gravity and pump-assisted distribution networks based on site topography.
What quantity of water do these systems support per day?
SPHERE humanitarian standards call for minimum 15 liters (4 gallons) per person per day for basic survival, and 50 liters (13 gallons) per person for full household needs. A single 10,000 GPD mobile treatment system combined with 50,000-gallon bladder storage can supply basic water needs for approximately 2,500 people for 24 hours. We size provisioning systems to population and duration requirements.
