The OneWater ^tm System

The OneWater^TM system can be customized to use ethernet or cellular data connection, and features a PLC and SCADA controller. The BMS (Building Management System) connection can utilize TCP/IP, BacNet, or MODBUS communication protocols. Remote monitoring, control, and data logging are included in every model size. Systems can be provided with shelf spares of critical components (pumps, membranes, disinfection units) to support continuous operation and regulatory compliance.

The OneWater^TM system can treat building greywater, which is wastewater collected from showers, laundry, and bathroom sinks. Approved non-potable end uses for treated water include toilet and urinal flushing, cooling tower makeup, irrigation, and clothes washing (where permitted by code). Learn more about the different types of wastewater.

The OneWater^TM system is designed for modular installation within mechanical rooms or basements of new construction projects. Our system is capable of fitting in odd shaped spaces and low ceiling height clearance areas. While retrofitting a system is possible, the current project would need to have dual plumbing infrastructure previously installed.

Project types include multifamily residential, commercial, mixed-use, hotels and resorts, community-scale developments, and more. Projects that are over 100,000 sq ft. and are looking to maximize effluent in multiple end uses see the most significant ROI. Learn more about the different types of projects we help, sample projects we’ve worked on before, and if onsite reuse is right for your project’s objectives.

Tank working volumes, foul air treatment, and instrumentation are customized to suit each project’s unique needs.

Loose ship components for field mounting are a standard inclusion in equipment packages.

Items that are not included as standard in equipment packages:

• Installation
• Interconnecting piping & wiring
• Reuse pump(s)
• Raw wastewater diversion (OPTIONAL)
• Potable water makeup w/air gap (OPTIONAL)
• Tank design & supply (OPTIONAL)
• Safety shower (OPTIONAL)
• Utility sink (OPTIONAL)
• Building & room features (structure, doors, lighting, hose bibbs, convenience outlets, etc.)

The following should be considered for integration:

• A three-way valve for diversion to treatment is preferable
• Sufficient storage for equalization, aerobic treatment, anoxic treatment, and non-potable water is required
• Appropriate waterproofing of storage tanks/cisterns is required
• A safety shower is required
• An operator/lab sink and work table is required
• Foul air treatment may be required
• Additional chemical storage may be recommended
• High-speed internet
• Remote viewing capabilities, such as cameras
• Leak detection
• Room drainage capacity
• Ongoing operations and maintenance

Effluent is treated to Disinfected Tertiary Recycled Water standards (e.g., California Title 22 or local equivalent), with typical performance including:

• Turbidity ≤ 0.2 NTU average within a 24 hour period 95% of the time, never to exceed 0.5 NTU
• Total/Fecal coliforms: < 2.2 MPN/100mL in a 7 day median sample, with no sample >23 MPN/100 mL
• Continuous chlorine residual monitoring 
• UV dose ≥ 80 mJ/cm² for virus inactivation
