RO plant online. Although decisions have not been finalized,
this option presents a compelling approach for consideration.
In May, testing of Beebe Draw began. As mentioned, this source
has high iron, manganese, and hardness and is classified as
GWUDI. Testing included evaluation of preoxidation and removal
of particulates and organics via coagulation, sedimentation, and
filtration. Due to the elevated levels of manganese, removal using
adsorption on greensand and induced oxide coated media is also
being evaluated. Pellet softening and precipitative softening are
being considered for hardness treatment. As of late May, this
testing had just been initiated and therefore results from the
testing are not yet available.
In addition to treatment of the South Platte alluvium and Beebe
Draw wells, Brighton is exploring ways to minimize future
demand. The city has an existing non-potable water system and
has been evaluating the impact of expanding the system. Since
significant new growth is happening in Brighton, expansion of
the non-potable system into these growing areas could reduce
future potable needs, flattening the demand curve. Balancing
the growth and demand needs, a focus on maintaining existing
infrastructure and options for offsetting demand with non-potable
water, Brighton’s approach is multifaceted and fiscally
responsible, and will ultimately provide taxpayers with the
