This makes sense because it allows a double use for the same pumping costs and mandatory wastewater treatment costs.

Disinfection does add to wastewater treatment costs (increasing overall costs by an estimated 5 percent to 10 percent).

Falcon says that one of its urinals saves 40,000 gallons of water a year and reduces wastewater treatment costs.

The wastewater treatment contract provisions allow for the city to be billed for its prorated share of the TRA's total wastewater treatment cost, which was 11.8% in fiscal 2006, the contract expires in 2023.

At CN’s Johnston Yard in Memphis, Tennesse, for example, a leaky 100-year old water distribution system was responsible for the facility’s excessive water usage, which increased wastewater treatment costs and created storm-water compliance issues.

Key words: wastewater treatment alternatives, treatment process, standards, receiving stream, stream system, joint treatment, separate treatment, wastewater treatment costs, decision analysis, systems analysis, Yamaska River, urban wastewater, industrial wastewater, economical implication.

Compared to submerged fermentation processes, solid state fermentation is more cost-effective: smaller vessels, lower water consumption, reduced wastewater treatment costs and lower energy consumption (no need to heat up water, poor mechanical energy input due to smooth stirring).

When the river is completely disconnected from the wastewater system, the stormwater from the river will no longer flow into a wastewater treatment plant but will instead flow directly into the River Seine, which is expected to lead to significant savings in wastewater treatment costs.
