N-Viro Soil

The Bio-Solids Division of Water Pollution Control houses perhaps the fastest growing program of the department: N-Viro Soil™. This innovative technology recycles and reuses the sludge by-product generated at the treatment facility.

The addition of the N-Viro Soil™ process has allowed us to discontinue a costly and time-consuming land application program and recycle wastewater sludge and other waste streams rich in organic matter into a safe, valuable product that can be beneficially reused. Most often used as fill dirt for city development and redevelopment projects, this recycled organic matter is an ecologically sound alternative to regular soil. Not only does it respond better to the environment because it contains fertilizer and absorbs water and other nutrients more fully, but it also saves taxpayer dollars because it requires less to help support plant growth.

Sewer Maintenance

This program has been effective in reducing pollutant discharge from combined sewer overflows and increasing the overall efficiency of the collection system. Specifically, the program oversees the:

• Inspection of new construction for conformance with the sewer ordinances and for the integrity of new sewers
• Inspection of existing sewers and manholes for structural conditions
• Cleaning of settled solids from certain sewer lines to maintain flow, increase sewer capacity and remove blockage
• Reconstruction of manholes and sewers requiring repairs
• Inspection of commercial and industrial users for compliance with discharge regulations
