The Town of Nederland Utilities Department needs your help to protect the Nederland area environment and also our Town’s Wastewater Treatment Plant which was constructed in 2013.  Please be careful of what you put down the drain. 


Nutrients can be dangerous to receiving waters.  High levels of phosphorous and nitrogen can cause a body of water to become “eutrophic” or over fed.  This can result in excess algae, unsightly growth and odor, and depletion of oxygen.  These conditions damage aquatic life and can jeopardize public health.  Excess Nutrients threaten Barker Reservoir and the water of those downstream from us. 

The State of Colorado limits the amount of phosphorous and nitrogen a wastewater treatment facility can discharge.  When excess levels of these nutrients come down the drain, extra treatment is required.  This raises the costs of wastewater treatment for the Town of Nederland.

What should we watch for?

Wipes & “Flushable” Products


Fertilizers are a common source of phosphorous and nitrogen.  Fertilizers should never be dumped down the drain.  Soaps and detergents can also be high in phosphorous.  Look for labels that say phosphorous free and/or watch for phosphorous related products in the ingredient list.


Trash put down the drain clogs pumps and makes wastewater treatment more difficult.  These difficulties can increase the cost of wastewater treatment for a community.

Nederland Biosolids Treatment Facility

Check here for ongoing updates from Nederland Public Works Manager Chris Pelletier, CWP.

October 2018: For several years Nederland has been planning the expansion of the Waste Water Treatment Facility to reduce operational costs and eliminate the remaining sludge pond. In June of 2018, voters approved to allow Nederland to borrow $2 million to fund this facility upgrade. Because of the efficiency of the proposed facility upgrade, Staff was able to secure a 0% interest loan. Additionally, the Town of Nederland received a grant for $950,000. At the October 16, 2018 Board of Trustees meeting, a contract with Fischer Construction Inc, was approved to begin construction. With funds secured and a construction contract in place, residents will begin to see construction activities at the Waste Water Treatment Facility starting end of October 2018. Staff will make monthly updates on the progress of construction. Please feel free to contact Nederland Public Works Manager Chris Pelletier if you have any further questions at 303-258-3167 (office) or 303-570-6039 (cell).
