Speakers: Chris Sanchez and Daniel Niemela, Bishop-Brogden Associates Inc.
Municipal water providers currently relying on Denver Basin ground water are pursuing renewable water resources to supplement or replace their existing non-renewable supplies. The transition to renewable water is driven in part by the escalating long-term cost to develop and operate Denver Basin well fields due to declining ground water levels, decreased well yield and high well density. Economic models are used to address the timing for new water supplies by incorporating variables such as current and future well yield, proximity to surface water supplies, availability of senior water rights, water quality and need for reservoir storage. The economics of several example water supply planning scenarios will be presented.
For the past 30+ years, ground water levels in densely developed areas of the Denver Basin have exhibited high rates of water level decline. Recent ground water level data from Denver Basin wells in northern Douglas County indicate a localized decrease in the long-term decline trend, with ground water levels even rising in some areas. Accordingly, future well yield projections based upon these recent data are more favorable. Recent water level data will be used as context to explore the economic sensitivity of the water supply planning scenarios.
