    No Registration through RMNASTT Site

    Project Description:
    The City of Aurora is constructing a horizontal Ranney collector well adjacent to the South Platte River near Fort Lupton.  While this well type is common in the Midwest, this is only the second Ranney collector well designed and constructed in Colorado. It consists of a 20-foot diameter, 35-foot-deep concrete caisson from ground surface to bedrock with ten (10) horizontal screened well laterals 200-feet long drilled horizontally and radially from the center of the caisson. The Caisson is complete and the Specialty Contractor, Layne, is currently drilling the screened laterals.

    Additionally, a new 36” diameter well manifold pipe will cross the South Platte River and will be constructed using a microtunnel boring machine (MTBM) to install a 48” steel casing pipe. The crossing required construction of watertight secant pile launching and receiving shafts to bedrock. Global Underground will be tunneling the 48” steel casing pipe initial support at the same time Layne is drilling the horizontal well laterals, so this is an exceptional opportunity to witness two unique construction and tunneling methods at once.

    We are excited to invite you to an exhilarating Mountain Bike and Hike event during the WEAU Conference on April 23, 2024. This outdoor adventure is tailored for all skill levels, from beginners to advanced riders.

    The 2024 Utah State Sporting Clays Championships will be held April 25-28 (Thursday thru Sunday), 2024, at Purgatory Clay Sports.  The preparation for this triennial event will not allow for the course to be opened on Tuesday, April 23, 2024, for the Rocky Mountain chapter of the North American Society of Trenchless Technologies (RMNASTT) Sporting Clay Shoot. We’ll miss not getting to see everybody that would attend and help this year, but we will be back in 2025. So, instead of hosting the sporting clay shoot, RMNASTT is joining with the WEAU YP’s to sponsor a mountain bike ride and hike!
