EPSD Profile

The District provides wastewater treatment to an estimated 3,200 full-time residents (CDPS# CO-0020290).  Since the primary industry of Estes Park is tourism, many of our commercial customers include lodging and restaurants that provide services for our guests. During the peak summer season it's estimated that our customer base increases by a factor of two.

Treatment Facility

The current facility was constructed in 1964, though many improvements have been made to meet more stringent effluent restrictions.  Current permitted capacity is 1.5 millions gallons per day.  The plant operates at approximately 50 - 55 percent capacity during the peak summer season.

The aerated facility uses an EQ basin to create an even flow into the plant.  The wastewater passes through a series of basins that modify air levels and create environments to encourage desirable biological activities.  Recycling a portion of the flow continuously enables the process to repeat and achieve further reductions before chlorination and de-chlorination.  The effluent is then discharged to the Big Thompson River.  

Collections

Collection of wastewater is accomplished through a network of main lines that total 28 miles and approximately 900 manholes.  Staff maintains these lines through scheduled cleaning, repair and replacement. 

During the past 20 years an aggressive improvement program has been in place.  Old and undersized clay lines have been replaced with new PVC mains.  While we still have clay lines in place today,  over two-thirds of our system is PVC, HDPHE or ductile iron. These replacements have greatly improved service reliability and lowered flow into our plant by reducing infiltration.  We are proud of this accomplishment and will continue this process in the future.  Attached is a map of our collection system.
