THE WATERHUB®W A T E R R E C L A M A T I O N & R E U S E F O R A N Y I N D U S T R Y

Sustainable Water is committed to changing the landscape of water resource management through on-site reclamation and reuse. Our commercial-scale water recycling systems (WaterHubs) reduce water supply risk, save millions of dollars in utility costs, and improve environmental stewardship. Through innovative performance financing, our turn-key projects can be designed, built and operated at no upfront capital expense to our clients.

From industrial parks to college campuses, custom WaterHub systems are suitable for any wastewater treatment or reuse application. Through ecological design, Sustainable Water develops highly efficient wastewater recycling systems tailored to each client’s unique site, design, flow and water quality requirements. With flexible site integration and an aesthetically-pleasing, odorless design, the WaterHub provides a sustainable water management solution for any industry or setting – urban or rural, off the grid or on.

INSIDE THE WATERHUBecologically-engineered water reclamation systems

Hydroponic systems involve a series of interconnected bio-reactors with lush vegetation growing above them. Plant roots extend into the reactors to provide a natural habitat for fixed-film and suspended microbial organisms that consume organic waste. This creates more complex and diverse ecosystems that quickly digest or remove organic pollutants from water. Plants enhance the treatment process through greater oxygen diffusion and microbiological habitat creation. Sustainable Water uses artificial media to mimic that natural root system in order to extend the surface area for this growth. Compared to traditional biological treatment systems, hydroponic treatment allows for significant reductions in physical footprint, sludge production, and energy use.

RECIPROCATING WETLAND (RECIP®) SYSTEMSReciprocating wetlands are engineered wastewater treatment systems that rely on principles found naturally in tidal ecosystems. In these systems, wastewater is alternately filled and drained in paired reactor cells on a recurrent basis. Each cell contains various rock mediums and water-adapted plants, which create a natural habitat for fixed-film biological growth. The fill and drain process naturally creates anaerobic, anoxic and aerobic environments that help break down waste through controlled microbial processes, such as nitrification and denitrification. By mimicking tidal principles [bio-mimicry], these systems achieve the lowest energy footprint of any engineered wetland system capable of producing reclaimed water quality.

HEAT & POWER:Large steam and power plants require extensive water demands for boiler makeup and cooling.

COOLING TOWERS:Cooling towers evaporate large volumes of water for commercial air conditioning needs, accounting for as much as 60% of a building’s total water footprint.

IRRIGATION & LANDSCAPE:Universities and large campuses can use up to 30% of their total water footprint on irrigation and landscaping.

TOILET FLUSHING:Nearly 1/3 of all water used indoors goes to toilet flushing in commercial spaces.

Treated reclaimed water is reused for non-potable demands such as utility operations and irrigation, minimizing potable water use on-site.

Water is mined directly out of the existing sewer network, reducing the amount of wastewater sent to receiving conveyance and treatment infrastructure.

Potable water treatment and distribution has extensive energy demands. Water drawn from local community stresses habitats and natural ecosystems.

Reduced effluent helps natural waterways by contributing fewer pollutants to

streams, waterways and the environment.

WATER PURCHASE AGREEMENTSustainable Water offers turn-key project financing opportunities through a Water Purchase Agreement (WPA). Similar to a Power Purchase Agreement, a WPA is a financing vehicle that allows Sustainable Water to fully construct and operate water reclamation systems at no capital expense or development risk to the end user. Under a WPA, Sustainable Water assumes all maintenance and operational responsibilities as well as all permitting requirements, bonding, construction risk and performance liabilities. Water savings produced by the project are used to pay off the cost of the facility over time; meanwhile, the end-user receives substantial guaranteed savings beginning Year-1 of operations. The agreement is highly flexible and can be tailored to any client’s financing criteria.
