K-001How Klarifi works

Public records goin murky. Leadscome out clear.Public records go in murky.Leads come out clear.

Klarifi is named after the clarifier, the tank where a treatment plant lets the solids settle. We do the same to the public record: collect it, let it settle, and hand your team what is left.

Field report 01
Sentry
10x
faster to a high-quality lead

Sentry’s sensors warn treatment plants of toxic and high-strength discharges. Its reps used to research every plant by hand. Now they go into the call with its daily flow, its recent violations and the industry upstream of it.

“We crushed our latest sales targets, in no small part thanks to the lead generation from Klarifi’s platform.”
Mack Pardy, Commercial Operations Manager
Field report 02
Legacy Watercare

Legacy Watercare. Mapped the plants with suspended-solids violations in the US Midwest, found a contact at every one, and planned the sales trips from the map.

“Thanks to Klarifi’s platform, we engage with the right people at the right wastewater treatment plants.”
Jeff Yorga, Sales Manager and Partner
Field report 03
EOSi

EOSi. Replaced manual market analysis with the platform, and found opportunities for nutrient removal that were not on their list.

“We now uncover opportunities we hadn’t recognized before, thanks to the platform’s great overview.”
Kevin Wilson, Inside Sales Specialist

Hi Dana, I saw that the city has funded a clarifier rehabilitation for 2026. We build the drive units for tanks of that size. Would a short call before design starts be useful?

It depends on the source. For some facilities we have weekly updates on discharge patterns.
