Decentralized Wastewater Systems for Housing Developments
Stop letting lack of municipal sewer access stall your development. A3-USA provides compact, American-made MBR systems for communities of 800 to 10,000+ homes.
Wastewater Solutions for Communities of all Sizes
Don't Let Infrastructure Costs Kill Your Deal
As a developer, you face a critical choice when municipal sewer lines are miles away or at capacity: pay millions in off-site trunk lines, or delay the project. A3-USA offers a third option: Decentralized Treatment. By treating wastewater onsite with our advanced MBR technology, you gain control over your timeline, reduce infrastructure costs, and create a sustainable water source for your community.
Made in the USA
Wasterwater Treatment Plants
A3-USA designs and manufactures membrane bioreactor (MBR), sequencing batch reactor (SBR), and conventional activated sludge (CAS) wastewater treatment plants. We are the only MBR plant integrator who manufactures the complete plant, including the membrane modules.
-
Compact Footprint MBR systems require significantly less land than conventional treatment processes, ideal for developments where space is at a premium.
-
Superior Effluent Quality The membrane barrier physically removes suspended solids, bacteria, and pathogens, producing water suitable for non-potable reuse.
-
Stable Performance Operating at higher biomass concentrations provides reliable treatment even as flows and loads change during development phases.
-
Regulatory Confidence Meet discharge requirements from day one while planning for future expansion with built-in compliance margins.
-
Reuse-Ready Effluent Treated water is immediately suitable for irrigation, landscaping, and other community non-potable applications.

Decentralized Wastewater Treatment for Growing Communities
Many master-planned developments benefit from decentralized or satellite wastewater treatment plants rather than a single centralized facility. Decentralized MBR systems allow treatment capacity to be distributed across the development.
- Align infrastructure investment with construction schedules
- Reduce upfront capital expenditures significantly
- Shorten conveyance distances and pipe infrastructure
- Simplify long-term system expansion
- Add capacity without disrupting existing operations
- Gain flexibility, redundancy, and resilience
For large residential developments, decentralized wastewater treatment communities gain flexibility, redundancy, and resilience—qualities that centralized systems often lack.

Frequently Asked Questions
What size communities benefit most from MBR systems?
MBR systems are particularly effective for communities serving 800 homes and above, where space constraints, regulatory requirements, and reuse opportunities make advanced treatment essential. A3-USA systems typically serve communities from 800 to over 10,000 homes with capacities starting at 200,000 GPD.
Can MBR systems support phased residential development?
Yes. MBR systems are well suited for phased growth, allowing treatment capacity to be added as new phases are developed without disrupting existing operations. A3-USA designs each system with built-in expansion paths, enabling capacity to scale alongside population growth.
Are MBR systems suitable for decentralized wastewater treatment?
Absolutely. MBR technology is ideal for decentralized and satellite treatment plants due to its compact footprint, consistent effluent quality, and scalability. Distributed treatment plants can be strategically located throughout a development, reducing conveyance costs and providing infrastructure flexibility.
Why does domestic membrane manufacturing matter?
Manufacturing membrane modules in the United States ensures quality control, supply-chain stability, and direct engineering expertise—resulting in more reliable long-term performance. A3-USA is the only company in the U.S. that designs and manufactures its own MBR membrane modules domestically.
What effluent quality can be expected from an MBR system?
MBR systems produce consistently high-quality effluent suitable for discharge compliance and non-potable reuse applications. The membrane barrier physically removes suspended solids, bacteria, and pathogens, delivering water quality appropriate for irrigation, landscaping, and other community uses.
How does A3-USA support projects throughout their lifecycle?
A3-USA works closely with consulting engineers, developers, and municipal stakeholders from early planning and system sizing through detailed design, construction, startup, and long-term operational support. This collaborative approach ensures each system is tailored technically, operationally, and economically.
