Overview

Mission

Provide a forum to advance and promote all aspects of Ohio's onsite wastewater industry.

What it reported doing in 2025

Educational programs

Operating model

Revenue model
Mixed. Its operating money came from several sources; no one source provided a clear majority.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Expenses are high relative to revenue and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
