What are Rewatec leach field chambers?

Rewatec leach field chambers are gravel-free infiltration units used in the final stage of a septic system. Instead of using perforated pipes and stone, they create an underground space where wastewater from your septic tank can safely disperse into soil.
With its lightweight, modular design, this system offers easier installation than traditional leach fields (often called drain fields), reducing installation time and site disruption.
Whether you're planning a new build or replacing a failed system, Rewatec leach field chambers are a reliable solution for:
- rural homes and cottages
- off-grid properties with limited access
- farms and hobby homesteads
- campgrounds and remote facilities
Why choose Rewatec leach field chambers?

Premier Tech's chambers offer a simple leach field installation without the hassles of traditional pipe-and-gravel systems.
Unlike conventional installations that require cutting, perforating, and aligning pipes, Rewatec leach field chambers feature integrated distribution channels with pre-punched holes that evenly disperse wastewater. There's no need for extra tools or materials.
Each chamber is durable, lightweight, and designed to easily lock into place. With fewer components and no heavy lifting, installers can complete the job quickly.
Because the system is gravel-free, there's no need to coordinate gravel deliveries or wait for truck shipments. That means fewer delays and a cleaner, more efficient installation process.
How do Rewatec leach field chambers work?
Septic systems with Rewatec leach field chambers work in 4 simple steps:
- Liquid leaves your septic tank
After solids settle inside the tank, partially treated wastewater flows out through an outlet pipe.
- Wastewater enters your leach field
The outlet pipe carries wastewater to your leach field, where it moves along integrated channels located at the top of each chamber.
- Wastewater drips inside the chambers
As liquid flows along the channels, it drips through holes and falls into the open-bottom interior of each chamber. The holes are sized and spaced to ensure wastewater spreads evenly across the entire leach field.
- Final treatment in native soil
Wastewater gradually seeps into native soil, where natural filtration removes remaining impurities before effluent safely returns to groundwater.
Built for sustainability and resilience
Each Rewatec leach field chamber is made from a single type of recycled plastic, making it easier to recycle than products with composite designs.
The plastic we use makes our chambers lightweight and tough. They're a breeze to handle on site and strong enough to last.
Because they’re stackable and compact, Rewatec leach field chambers are simple to ship in large quantities. That helps reduce emissions and the environmental impact of transportation.
