Can large outdoor fountains, waterfalls or ornamental ponds be operated?
A. Yes. Q. Can I use graywater (water from my washing machine, tubs, or sinks) to water my outdoor vegetation. A. No. The use of graywater is regulated by the Tri-County Health Department. Graywater use is a public health issue because it contains harmful bacteria and viruses. Both graywater and black water (water from toilets) are regarded as wastewater. Tri-County Health Department regulations state that for any home serviced by a public sewer system, all wastewater must go down the drain. Since Thornton residents are serviced by a public sewer system, graywater use in Thornton is prohibited.
