Water Conservation

Conserving Water and Protecting Groundwater with Your Well or Septic System

Groundwater is a largely non-renewable resource, and as population increases in the Denver Metro Area, there is increased demand on both surface water and groundwater resources. As a result, the supply of clean water is rapidly decreasing. The water tables in the Denver Basin aquifers have fallen each year; alluvial wells are less able to recharge, and a growing population has increased demand for water resources. 

By conserving water and using it efficiently we can extend water supplies and energy. This is important as our growing population places greater demands on our water supplies. Small changes add up!

As a septic system or private well owner, you are perfectly positioned to conserve water and protect our groundwater from contamination.

To learn more about water conservation when you have a private well and septic system, please visit the links and resources below.

Calculating Your Water & Energy Use

Curious to find out where your household uses water the most and what your annual carbon footprint is per year? Try the Alliance for Water Efficiency's Home Water Works Calculator. The Calculator provides a nice overview of your results. The data are presented by family size, landscape size and zip code, to give you a better idea how your water use compares with similar households. Your carbon footprint – for heating water – is part of the results page, too. They even give you recommendations and resources for how to save more water and energy.
