McGregor Square Dewatering

Colorado Rockies’ West Lot, now officially known as McGregor’s Square, features a plaza, residential space, hotel, retail, restaurants and more, which opened in 2021.

RK Water began temporary construction dewatering in December 2018 and continued for six months through May 2019. The pumping of groundwater was managed by a series of interconnected sumps inside the excavation. RK Water’s expertise in groundwater management and mitigation permitted Hensel Phelps and its subcontractors to excavate down to bottom-of-grade and to pour the foundations of McGregor’s Square ahead of schedule. Over the period of six months, over 30,000,000 gallons of groundwater were pumped out of the excavation and treated. In addition to pumping the groundwater out of the excavation, RK Water treated the groundwater for contaminants including arsenic, cadmium, lead, selenium and tetrachloroethylene.
