Wastewater
The disposal and treatment of municipal and industrial wastewater results in the emission of CH 4 and
N2O. The amount of CH 4 produced depends on the organic content (or loading) of the water (expressed
in terms of biochemical oxygen demand); wastewater with a high biochemical oxygen demand (BOD)
will emit more CH4. Emissions of N2O depend on the nitrogen content of the wastewater, which is itself
dependent on the consumption of dietary proteins in the population.
7.3.1 Historical Emissions
Wastewater emissions in Nevada are a minute source of the state's total GHG emissions. Nevada's total
wastewater emissions in 2013 were 0.302 MMTCO2eq. Because wastewater emissions are in general
tied to population, every year that the state's population increases the emissions associated with the
treatment of wastewater will likely also increase. Table 7-3 lists historical wastewater emissions and
Figure 7-3 shows the historical emissions from 1990 to 2013. Note that the emissions associated with
the treatment of industrial wastewater are negligible.
