Water Recycling System

What is Water Recycling System?

A water recycling system filters and reuses recovered water on a hydrovac or combination truck, extending runtime between refills by turning captured slurry or jetting water back into usable supply.

A water recycling system separates solids from the water the truck recovers, then feeds the filtered water back to the high-pressure pump. On combination trucks this lets crews jet sewers far longer between hydrant fills; on some hydrovac units it reduces water hauling and downtime.

Recycling boosts productivity and cuts water consumption, which is valuable on long municipal cleaning runs and remote sites. Availability varies by unit, so it is worth confirming when matching equipment to a job. Submit a free Vac4Rent request and rental companies can identify units with recycling.

Water Recycling System: common questions

What is Water Recycling System?+

A water recycling system filters and reuses recovered water on a hydrovac or combination truck, extending runtime between refills by turning captured slurry or jetting water back into usable supply.

Does a water recycling system replace the need for a water truck?+

Not entirely. A recycling system extends how long a truck can work between fills, but some water is lost with the removed solids and during processing, so the supply still needs topping up. On long runs or remote sites without hydrant access, contractors may still pair the unit with a water truck or plan refill stops. Recycling reduces how often refills happen rather than eliminating them, and results depend on the system and the material being handled.

Is recycled water on a combo truck suitable for every job?+

Recycled water works well for many sewer and storm line cleaning jobs, but it can still carry fine particles after filtration, which may add wear to pumps and nozzles. Crews may switch to fresh water when the recovered water is heavily loaded with grit or grease. Rules for discharging recovered water also matter, since it is often treated as wastewater and cannot simply be released on site. Check local requirements before planning any discharge of recovered water.

What should I ask about a water recycling system before renting?+

Ask whether the recycling system is installed and working, what maintenance it needs during the rental, such as screen or filter cleaning, and who is responsible for it. If an operator is included, confirm they are trained on the system. It is also worth asking whether the system is meant for jetting only or also for hydro excavation, and how it performs with heavy grit or grease, which can clog filters and slow the work.
