This technology enables these systems to complete an entire day of cleaning with just 1,000 gals of water, as opposed to the more than 8,000 to 10,000 gallons of potable water used by traditional water jet sewer cleaning systems.
Water agencies across California are currently under significant mandates imposed by the State to reduce the use of available potable water. “Utilization of these Water Recycling units by California sewer agencies could be a significant step in achieving water reduction goals,” says National Plant Services president Dennis Keene. “The efficiencies and savings these systems offer will significantly reduce the volume of clean water required for sewer cleaning.”
The new mobile systems, RECycler 315 water reclamation truck-based units made by J. Hvidtved Larsen A/S of Denmark, use a five-step continuous cleaning process employing filters and settling tanks to clean jetting water and recycle it for re-use.
Larsen trucks, while new to the United States, are widely used and valued across Europe for their ability to reduce water use. National Plant Service is currently the only company in the western United States with these trucks.
High-velocity water jet cleaning of sewers is an extremely efficient and effective technique, but requires high volumes of water. The capability of the RECycler 315 to capture and recycle that water reduces water use without affecting in any way the effectiveness of the cleaning. In addition, since traditional water jet cleaning trucks cannot carry the full volume of water they need for a day of cleaning, cleaning operations stop repeatedly in order to replenish water needed to operate significantly reducing operational efficiency. The new National Plant Services trucks can work continuously until the day’s work is complete, increasing efficiency and reducing costs.
