City of Glasgow Water Treatment Plant Rehabilitation and Retrofit

City of Glasgow Water Treatment Plant Rehabilitation and Retrofit The City of Glasgow recently completed a $7 million upgrade to their water treatment plant (WTP). Originally a 1960s groundwater softening plant, and converted to surface water treatment in 1987, the upgrade rehabilitation and retrofit project installed modern technology to treat the low turbidity source water. All components of the upgrade were constructed within the existing building footprint. Older technology replaced with package units for specific treatment goalsThe existing plant was built as a groundwater softening facility in 1966. The plant was converted to Missouri River water in 1987, which remains the current, high-quality and low-turbidityRead More →

Avoiding Pitfalls: Commissioning Water Treatment Plant Rehab and Retrofit Projects

Avoiding Pitfalls: Commissioning Water Treatment Plant Rehab and Retrofit Projects By Jeff Ashley, PE – The design and construction of a water treatment plant is a collaborative effort between engineers, owners/operators, contractors, manufacturers, regulators, and funding agencies. While the design responsibilities lie with the engineering team, typically the contractor and manufacturers work with plant operations staff during the commissioning phase. Commissioning demonstrates that the water treatment plant processes, as designed and constructed, will operate reliably to meet drinking water standards. The commissioning process is even more complex when the project involves the rehabilitation of certain plant components and retrofitting the plant with new processes andRead More →

Pre-Sedimentation Solutions and Benefits for Water Treatment Facilities

Pre-Sedimentation Solutions and Benefits for Water Treatment Facilities By Bill Wiegand, PE & Jeff Ashley, PE Pre-sedimentation (pre-sed) is an effective water treatment method, often utilized with source waters that have high solids, turbidity, and/or organics during certain times of the year, such as spring runoff. The pre-sed process helps reduce these materials from the raw water to more acceptable levels. As a result, other primary treatment processes such as high-rate settling and filtration are greatly improved and optimized. Pre-sed systems can be built to site specific needs to address unique raw water quality in lakes, rivers and streams. The pre-sed process can involve fairlyRead More →
