PROJECT TYPE: Parks/Recreation/Ranches
SERVICE: Construction; Start-up / Operations
TECHNOLOGY: Textile Filter
LOCATION: Rocky Mountain National Park, CO
DESCRIPTION: In the Spring of 2011, IWS completed the construction of an Orenco AdvanTex wastewater treatment system for Peaceful Valley Ranch just South of Colorado’s famous Rocky Mountain National Park.
We enjoy working with IWS and appreciate their technical and construction expertise and approach to onsite wastewater projects. We would recommend them to others for onsite projects and look forward to working with them again in the future
Wastewater is transported from the Ranch facilities to the treatment system via a septic tank effluent gravity (STEG) system. Septic tanks are located adjacent to the ranch facilities that remove the majority of the solids in the waste stream. From there, the resulting effluent travels by gravity through small diameter collection pipes to the septic/settling tanks located at the location of the treatment plant.Effluent then flows by gravity to the recirculation tank and is pumped to the AdvanTex Filters. Following treatment in the filters, the effluent is diverted to a dose tank and then pumped through an ultraviolet disinfection system and then discharged directly to the Little South St. Vrain River. Due to very cold temperatures, heated air from the control building is piped underground to each of the treatment pods to maintain adequate temperature in the filters and prevent freezing.Since the site is located in a very rocky valley on the banks of the Little South St. Vrain, excavation of huge boulders was necessary in order to set the tanks. Additionally, groundwater was encountered at shallow depths requiring a discharge permit and dewatering to the river.
Peaceful Valley Ranch is the fifth project that IWS and Church Onsite Wastewater Consultants have worked on together. Bob Wright commented on the IWS relationship, “We enjoy working with IWS and appreciate their technical and construction expertise and approach to onsite wastewater projects.
