Welcome to the North Table Mountain Water and Sanitation District web site. For over 55 years the District has provided high-quality water and sewer service to the Fairmount Community as well as portions of the Cities of Arvada, Golden and Wheat Ridge. We currently provide service to over 10,000 residents, businesses and industries. Inside these pages, we have attempted to answer many of your questions regarding water rates, billing, water conservation and payment options.

A temporary switch of our source may cause some changes in our water taste:

Beginning October 15, 2021, Ralston Reservoir, the District’s source for raw water, was drained and shut down for a planned nine month maintenance period by Denver Water.  In preparation for the outage North Table Mountain worked with the City of Arvada and Denver Water to install and interconnect with a new raw water pump station and pipeline from the Arvada/Blunn Reservoir.

We are currently receiving and treating water from the Arvada/Blunn Reservoir.  Although this reservoir is filled with the same sources of water that we normally receive the taste and odor elements that are generated in the reservoir are slightly different than Ralston Reservoir.  We would like to assure our customers that the finished water chemistry and quality is as safe as ever however the taste and odor profile will be a bit different this winter.  The Ralston Reservoir will be back in service by May of 2022 and we look forward to returning to the normal source that our customers are used to.

Following is a an article from Denver Water describing the work they are doing on the raw water system:

The Metro Wastewater Reclamation District (Metro District) reminds Denver area residents to refrain from flushing anything but toilet paper, including:

  • All types of wipes (even wipes labeled as flushable)
  • Paper towels, napkins and all other paper products
  • Toilet bowl scrub pads
  • Diapers
The items above should be placed in the trash and not flushed down the toilet.  This is a particularly important reminder following the toilet paper shortage that has resulted from the coronavirus COVID-19 outbreak.  While products other than toilet paper can cause operational challenges for wastewater treatment facilities, they can also create blockages in residential pipes.
As critical regional infrastructure, the Metro District is taking measures to ensure the organization will continue to provide consistent wastewater treatment service to the metropolitan Denver area as this situation evolves
