Man Camp Remote Water Treatment

Drinking Water and Sanitation Solutions for Isolated Mining Sites

Since mining, oil and gas, and some industrial operations can be located in isolated areas, remote water treatment solutions are needed to process local water for drinking and sanitary use. These locations are often short-lived as the sites may be further developed or abandoned at some point.

Considering the temporary and remote nature of the need, WesTech offers packaged equipment that’s easy to transport and set up at the site. Frequently, our treatment solutions are skid-mounted or built within a standard container for easy shipping and installation.

Water Sources

Possible water sources for these sites typically consist of rivers, streams, or lakes. These sources may have high suspended solids levels and may also be contaminated with microbiological organisms. In addition, there may also be seasonal changes in the water quality, i.e., higher suspended solids in the springtime due to rain runoff.


An effective way to deal with these sources of raw water is a packaged treatment plant consisting of a coarse up-flow clarification followed by a plate-type separator and finally a multimedia filter. The WesTech Trident® system has proven itself in thousands of applications to be able to handle high and varying solids while producing a stable high-quality effluent. Effluent from the system is often of sufficient quality to be used for various process water applications at the site.

In order to make the water potable (safe for drinking), one of the most efficient and effective ways is to treat it through ultrafiltration membranes, like those in the WesTech AltaPac™ UF membrane package system. These membranes have sufficiently small pore sizes to remove 99.99 percent of all microbes, including Giardia cysts and Cryptosporidium. After treatment with ultrafiltration, the water is typically treated with either chlorine or ultraviolet light to ensure it is safe.


The other half of the equation at these sites is to treat the sanitary waste generated. As with most “municipal” systems, these waste streams peak in both volume and contaminant levels at certain times of the day, in this case typically at shift change. A system that can handle these spikes in quantity and quality is therefore required. The system also needs to operate with little operator attention. Since power is normally at a premium on these remote sites, a system with low horsepower requirements is extremely desirable.

The STM-Aerotor™ meets all these requirements. It has the lowest ratio of horsepower per pound of dissolved oxygen of any commercial biological treatment. It uses conventional mixed liquor activated sludge technology in addition to fixed film biological growth to provide the maximum biological treatment in the minimum footprint. As with conventional activated sludge treatment, the STM-Aerotor employs a downstream clarifier to settle the biological solids.
