DGR Engineering
The project included full services for a 1.4 mile 115 kV line. The project required coordination with many different entities, including other power companies for coordinating the interconnection, and with a railroad company for right-of-way permitting, which included coordinating an inductive interference study. DGR services for this project included permitting, coordinating the design survey, design, construction administration, construction staking, and resident project observation.
SLRW has been a trusted provider of safe drinking water for over 40 years, serving more than 2,000 customers across agricultural, residential, commercial, and industrial sectors, including bulk water sales to four communities. Historically, water treatment involved only chlorination due to the high quality of well water.
Increased system demand and the addition of new wells led to elevated iron and manganese levels, exceeding acceptable standards. This necessitated the construction of a new water treatment plant (WTP) to ensure continued compliance and service reliability.
The plant was designed with expansion in mind, including space for additional filters to meet future demand, especially given proximity to the growing Sioux Falls Metro Area. Construction occurred on the site of existing facilities. Strategic reuse of infrastructure minimized disruption and reduced costs.
Electrical system redundancy was built into the design, including separate motor control centers (MCCs) and redundant cabling, minimizing the likelihood of prolonged disruption to plant operations.
DGR Engineering worked closely with SLRW staff and leadership to determine optimal plant capacity and select treatment technologies aligned with operational preferences. The project emphasized long-term sustainability, operational flexibility, and strategic foresight.
The new WTP equips SLRW to meet current and future water quality standards, supports regional growth, and ensures reliable service for decades to come.
