The Sanitation Districts have played a significant role in reducing air emissions and developing emissions controls in our solid waste management and wastewater treatment operations. Past and ongoing projects include: processing landfill gas into compressed natural gas (CNG) for use as an alternative fuel; developing emissions control technologies for heavy-duty vehicles; converting Districts-owned transfer trucks to alternative fuel; purchasing CNG vehicles; and constructing CNG fueling facilities at various Sanitation Districts' locations.
