Cleaning Up Our Water: How a Local Plant is Making a Big Difference

Water from homes travels through pipes to a treatment plant. There, it undergoes several steps to become clean again.

The Treatment Process

Initial Screening
- Large items like sticks and plastic are removed.
Primary Treatment
- Oils and greases float to the top.
- Solids sink to the bottom.
Secondary Treatment
- Bacteria break down organic matter.
Tertiary Treatment (Optional)
- Water is filtered and treated with chemicals or UV light.

The Page Wastewater Treatment Plant

Serves: Approximately 7,000 people.
Releases treated water into: The South Fork of the Coeur d’Alene River.

Recent Upgrades

Until recently, the plant lacked tertiary treatment, allowing extra nutrients and metals to enter the river. Thanks to funding from Idaho Governor Little’s initiative, the plant aims to reduce phosphorus by up to 7,000 pounds per year.

Why it matters: Just one pound of phosphorus can cause 500 pounds of algae, leading to water quality issues.

Construction and Progress

Duration: Two and a half years of upgrades.
Pilot Study: Helped determine the best technology and equipment.
Design and Procurement: Started in fall 2024.
Construction Began: May 2025.

New Structures

Chemical Systems Building
Solids Contact Clarifier (SCC)
- A large circular concrete structure.
- Involves intricate wood forms, reinforced steel, and careful pouring.
- Cold weather adds challenges, but progress is being made.

Completion Timeline

Expected Completion: July 2026.
Final Touches: September 2026.

Impact

This project is a significant step toward improving water quality in the Coeur d’Alene River. It highlights the importance of investing in modern treatment technologies. The plant's efforts will help protect the river and the environment for years to come.
