Why It's Important

The Integrated Plan provides an affordable and strategic plan to enhance our community, protect water quality, and ensure long-term viability of our system.  The Integrated Plan prioritizes capital improvements over a 25-year schedule to optimize wastewater treatment, maintain the integrity of our collection system, and comply with Clean Water Act requirements.

 

Wastewater Treatment is Essential to Johnson County

Wastewater treatment is the first defense against prevention of disease outbreaks and is essential to stream health and protection of the environment. Imagine how different your life would be if you didn’t have sanitary sewer services. In your home, the shower, kitchen sink, washing machine and toilets – all send flow to an interconnected, reliable wastewater treatment system.

Wastewater Sources (residential)

The everyday appliances we use in our homes, schools and businesses produce the wastewater that JCW collects and processes. In our homes, wastewater flows into the main sanitary sewer drain under your house, which connects to JCW’s sanitary sewer system at the edge of your property. The JCW sanitary sewer system directs all wastewater to the closest wastewater treatment facility. The volume of water used by plumbing fixtures, appliances, toilets, baths, laundry machines and dishwashers results in wastewater being 99 percent liquid.

Various Wastewater Treatments Used at JCW

Liquid and small particles

Biological Nutrient Removal Basins 

Air is circulated and bacteria remove dissolved pollutants, phosphorus and nitrates.

Secondary Clarifier 

Additional biosolids are separated from the liquid and piped back to the digester.

Effluent Filtration 

Liquid is filtered to remove any remaining small particles.

Disinfection

Effluent is disinfected with either ultraviolet light or chlorine before being discharged to a stream or river.

Wastewater from home or business enters sanitary sewer

Primary treatment

  • Grit removal: gravity pulls larger particles to the bottom

  • Primary clarifier: solids are separated from water by settling to the bottom of the clarifier

Sludge (biosolids) sent to the digester

Digester

A biological process that reduces the volume of organic materials and destroys pathogenic bacteria to convert the sludge to recyclable biosolids. Also produces methane gas for energy recovery.

Dewatering

Water is removed from the digested biosolids to produce a semi-solid byproduct that is loaded into trucks.

Biosolids

Biosolids are used as a soil amendment and fertilizer for crops not destined for human consumption.
