Leveraging nature-based infrastructure to achieve Water-Positive goals — scalable water replenishment, verified performance, operational in 12 to 18 months.
SWIG designs, builds, and operates custom water replenishment systems for corporations that need to meet Water-Positive, replenishment, or volumetric water benefit (VWBA) commitments in the watersheds where they operate. We sell the system and provide the full delivery service — site identification, permitting, construction, monitoring, and long-term operation — so a corporate water goal turns into a real, verified, watershed-scale outcome on the ground.
Volumetric Project Opportunities Map
The Two-for-One Advantage
SWIG's systems deliver massive volumetric water replenishment while simultaneously removing nutrients, PFAS, heavy metals, and dozens of other contaminants.
Every gallon replenished is also a gallon restored — creating measurable watershed-health improvements that strengthen your water stewardship story and your community relationships.
Application areas include Florida stormwater ponds and wet detention systems, constructed and natural wetlands under permit compliance, littoral shelf restoration, golf course water features, and conservation area management. The system handles dense herbaceous growth and woody invasives up to 2 inches in diameter, with harvested material available for on-site composting, off-site disposal, or beneficial reuse as agricultural mulch or biomass.
Built for the watersheds your facilities depend on
Our systems have a small footprint and high throughput, so they can be sited on a relatively small parcel and placed close to the impaired waters that matter to your operations and your community. At the standard 1.5 MGD-per-acre loading rate and 85% uptime, system economics scale as follows (values shown for a representative 4-challenge VWBA 2.0 D-6 configuration; site-specific FI confirmed in Phase 1):
That density means you do not need a large rural land assembly to deliver a meaningful VWBA result. SWIG locates and engineers the project where the water concern actually is — in-basin, in the impaired assessment unit, close to the facility, and close to the community that benefits.
How it works
SWIG's nature-based and circular-economy systems use proprietary recycled and reusable media to treat impaired surface water and replenish surface and groundwater systems. Our systems require no chemical input, minimal staffing, and are gravity-fed or pump-assisted. They are deployable in-ground, as floating platforms, or as scalable modular vaults — anywhere in the world, operational in 12 to 18 months.
What we sell and what we deliver
We sell the system and provide the services to make a corporate water commitment real on the ground:
- Site identification and watershed targeting in the basin of your facility, anchored to the documented impairment and the right assessment unit.
- Custom system design and engineering sized to your replenishment volume, footprint, and water-quality target.
- Permitting and partnership development with the local utility, regional water authority, and state agency.
- Construction and commissioning in 12 to 18 months.
- Operation, monitoring, and verified third-party reporting that supports VWBA Method D-6 ("Volume Treated") credits and your ESG / Water-Positive disclosure.
- Multi-format deployment — in-ground, modular vault, floating platform, or stormwater vault — selected to fit the site you can actually obtain.
Corporate Water Stewardship applications
- Direct water replenishment. Treat and restore impaired water in the same watershed as your facility. Every cubic meter treated generates verified, auditable volumetric water replenishment toward your Water-Positive goal.
- Indirect power-water footprint. Our systems have the replenishment capacity to address the 5–10x larger water footprint embedded in thermoelectric power generation that supplies your operations, cost-effectively.
- Community and stakeholder value. Visible, local water-quality improvement that builds community goodwill, supports local permitting for new facilities, and creates a compelling water stewardship narrative for ESG reporting.
- Scalable, multi-format deployment. In-ground, modular vault, floating, and stormwater-vault systems deployable across all major U.S. corporate footprints. Pre-identified candidate sites in priority regions, with indicative pricing.
