How NapaSan Delivers Recycled Water for Irrigation with Portalogic Stations

July is Smart Irrigation Month — and as one of the peak months for outdoor water use, it's the perfect time to look at how communities are rethinking where their irrigation water comes from. Across California, recycled water is emerging as one of the smartest, most sustainable answers to that question. But making recycled water available for irrigation isn't as simple as opening a valve. It takes the right infrastructure, careful oversight, and a system that keeps every gallon accountable.

That's exactly what our partnership with NapaSan in Napa, California, was built to deliver.

Why Recycled Water Matters for Irrigation

Recycled water — also known as reuse water — is high-quality water that has been treated so it can be safely and sustainably used for irrigation. NapaSan produces recycled water clean enough for irrigation use, giving local growers and property owners an alternative to drawing down limited potable supplies. It's a resource that protects drinking water supplies, powers agriculture, and promotes efficient water usage all at once.

At EleMech, supporting those goals is at the heart of what we do.

NapaSan by the Numbers

The scale of NapaSan's operation shows just how much a well-run utility can contribute to regional water sustainability:

• 8 million gallons of wastewater treated on an average day
• 83,300 people served across the community
• 700 million to over 1 billion gallons of recycled water produced annually

The Challenge: Regulated Distribution

For customers connected to a recycled water pipeline, distribution is relatively straightforward. The harder problem is serving the customers who aren't connected to that pipeline. For those users, recycled water can be transported to the property by truck — hauled either by the customers themselves or by a hauling company they hire.

In California, the production and use of recycled water is regulated by the state, meaning that any reuse water access NapaSan offers to customers must be tightly controlled. As the local agency responsible for issuing permits for recycled water uses within its sphere of influence, NapaSan must ensure multiple program requirements are met:

• A signed agreement between the recycled water user and NapaSan that binds the user to the reuse program rules
• Proper labeling on every truck or tank, verified through inspection, notifying the public and workers that the water is not fit for human consumption
• Training for the truck driver on correct filling procedures and emergency response
• A truck hauling permit, carried in the vehicle at all times, issued for a modest annual fee

Delivering hauled recycled water safely and in compliance with those requirements calls for a solution built specifically for the job.

The Solution: Controlled Hauler Access

To meet that challenge, we provided NapaSan with Portalogic Water Filling Stations for the distribution of hauled reuse water.

Portalogic stations are designed to give utilities like NapaSan controlled, accountable access to recycled water. Rather than relying on manual processes and paper records, the stations manage hauler access and can even allow temporary account deactivation should users not comply with regulations— making sure only permitted users can fill up, tracking usage, and creating the accountability that state oversight demands.

In short, Portalogic stations are part of the solution that ensures NapaSan customers not connected to a recycled water pipeline can still meet state-mandated requirements for hauling recycled water. Haulers get reliable access to a valuable resource, and NapaSan maintains the oversight and documentation the state requires — every gallon accounted for.

Smart Irrigation, Backed by Accountability

Smart irrigation is about more than simply using less water. It's about managing every gallon responsibly, connecting communities to sustainable water sources, and doing it all with the accountability to back it up.

The NapaSan partnership is a clear example of how the barrier to offering reuse water as a resource is rarely the water itself— it's building a distribution model that keeps access controlled, usage tracked, and compliance intact. By pairing a valuable recycled water supply with the infrastructure to distribute it accountably, NapaSan is putting reuse water to work for local agriculture while safeguarding the resource for the wider community.

Smart solutions like Portalogic show how technology can be a driving force in the future of agriculture and environmental stewardship, and how modern tools can make recycled water programs practical, scalable, and accountable. This Smart Irrigation Month, that's the kind of forward-looking solution EleMech is proud to help make possible.
