Rather than building for the community’s ultimate capacity at the start, phased and modular treatment allows infrastructure investment to grow with demand.
Align capital investment with current needs while remaining flexible
Municipal water and wastewater infrastructure is expected to serve communities for decades. But communities rarely grow in a perfectly predictable way.
In the United States, communities grow through new residential, commercial, and mixed-use developments. These developments are frequently built in phases, with a private developer responsible for the initial infrastructure and construction.
The first phase can be particularly challenging. The developer may know the community will eventually require significant water and wastewater capacity, but not on day one. Making a large upfront investment in treatment infrastructure designed for the community’s ultimate buildout can be difficult to justify when only a portion of the homes or businesses are occupied.
Connecting a new development to a large, centralized municipal treatment system can also require substantial upfront investment in pipelines, pumps, and other infrastructure. For a developing community, these costs can be significant.
Rather than building for the community’s ultimate capacity at the start, phased and modular treatment allows infrastructure investment to grow with demand.
A modular system can provide the treatment capacity needed during the initial phase, with capacity added as the development grows. For developers, this can help align capital investment with current needs rather than committing significant resources to infrastructure that might not be fully utilized for years.
For municipalities, the approach offers a more flexible pathway to incorporate new developments into water and wastewater infrastructure.
Municipalities and Developers Are Rethinking Traditional Infrastructure
Traditional water and wastewater projects can require significant capital investment, extensive site work, long design and construction schedules, and large footprints. That approach makes sense when future demand is predictable, and there is space, budget, and time to build a large facility. But for a new development, the economics can be different.
Phased and modular infrastructure offers another option.
Instead of making the entire investment up front, developers and communities can deploy treatment capacity based on the current stage of development and expand it as demand increases. This can help align infrastructure costs with the pace of growth while providing a clear pathway toward the community’s long-term needs.
Modular Treatment Can Support Existing Infrastructure
Modular infrastructure doesn’t necessarily mean starting over.
Many municipalities already have significant investments in treatment infrastructure. The challenge is figuring out how to increase capacity or improve treatment without abandoning what is already working.
A modular treatment system can integrate with existing infrastructure to add capacity or meet specific treatment requirements. This can expand capacity during population growth, support new development, upgrade an existing facility, or provide interim capacity while a larger plant expansion is planned.
Fluence’s Aspiral™ Flex is designed for this type of flexibility. The modular, containerized wastewater treatment blocks can serve as a complete plant or complement an existing facility. The units are pre-engineered and factory-tested and are housed in 20- or 40-foot containers for streamlined delivery and installation.
Aspiral™ Flex: A Modular Approach to Wastewater Treatment
Aspiral™ Flex combines Fluence’s membrane aerated biofilm reactor (MABR) technology with a modular, containerized design.
It is designed for small- to medium-sized communities and facilities, with configurations that can treat approximately 5,000 to 250,000 gallons per day. Communities can combine units to add capacity as requirements increase.
This creates a flexible approach to municipal wastewater infrastructure. It’s particularly useful for phased residential development, new commercial areas, and growing communities.
Decentralization: Bringing Treatment Closer to the Point of Need
Phased infrastructure can also support a decentralized approach.
In a conventional, centralized system, wastewater from a new development must travel long distances through expensive sewer infrastructure to reach a central treatment plant. The farther a development is from existing municipal infrastructure, the higher the costs.
Decentralized treatment takes a different approach by treating wastewater closer to where it is generated.
Fluence has implemented decentralized treatment using modular Aspiral™ systems in communities and remote locations where connecting to centralized infrastructure is impractical or cost-prohibitive.
This approach can support growing communities outside existing sewer networks, new residential developments, remote communities, rural areas, resorts, commercial developments, and satellite municipal facilities.
By treating wastewater closer to the point of need, communities reduce the infrastructure required to transport wastewater to a distant centralized facility. It also creates opportunities to reuse treated effluent.
For example, treated wastewater can be reused for landscape irrigation, gardening, and other nonpotable applications. Instead of sending wastewater to a centralized treatment plant and building a separate pipeline to bring treated water back to the development, decentralized treatment treats and reuses water close to where it is needed.
This reduces the infrastructure needed to deliver reclaimed water while lowering demand for potable water. For developments where irrigation represents a significant portion of water use, reusing treated effluent locally can reduce water costs.
Treating and reusing water near the point of use can turn wastewater from a disposal challenge into a resource.
Modular Treatment for Growing Drinking Water Demand
The same principles apply to drinking water.
New developments might require additional potable water capacity as homes, businesses, and other facilities come online. Building a large water treatment system before that demand exists can create the same economic challenge as for wastewater infrastructure.
Fluence’s NIROBOX™ line provides modular, containerized water treatment systems for freshwater, brackish water, and seawater. The systems can operate individually or in combination, allowing treatment capacity to scale with site requirements.
NIROBOX™ FW, for example, treats water from sources such as rivers, lakes, and wells. A single unit can produce up to 1 MGD, and units can be combined for larger requirements. Fluence also offers NIROBOX™ BW and NIROBOX™ SW for brackish water and seawater treatment.
For communities facing changing demands or limited water resources, modular treatment offers another option to expand capacity without relying on a single large, centralized facility.
Faster Deployment Can Matter
Water infrastructure projects can’t always wait years for a conventional expansion.
A new development might require water and wastewater services well before a major centralized infrastructure project could be completed. A municipality might have an urgent capacity requirement or regulatory target that requires quick action.
Because Fluence’s modular treatment systems are pre-engineered and factory-tested, much of the system can be prepared before arriving on-site. This can reduce on-site labor and simplify installation compared with conventional, site-built treatment approaches.
For developers and municipalities, faster deployment can mean getting needed treatment capacity online sooner while minimizing disruption to the surrounding community.
A More Flexible Approach to Municipal Infrastructure
Phased and modular treatment isn’t about replacing every centralized treatment plant with containers. Instead, it gives developers and municipalities another tool for solving infrastructure challenges.
Modular treatment can provide the capacity needed during early phases without requiring the full investment for ultimate buildout. The system can continue operating as a decentralized solution, supplement a larger municipal system, or serve as a bridge as the community transitions to other municipal infrastructure.
The ability to reuse treated effluent locally adds another layer of value. When water is treated close to the development, the same system can provide reclaimed water for irrigation and landscaping, reducing the need for additional reuse infrastructure and lowering potable water demand.
The right approach depends on the community, water source, regulatory requirements, available land, existing infrastructure, and long-term growth projections.
Fluence’s portfolio of modular water and wastewater technologies, including Aspiral™, Aspiral™ Flex, and NIROBOX™, allows communities to build treatment systems around specific requirements.
