Site work for a water / sewer project in Delaware, Ohio. Design plans call for site work for a water / sewer project.

The NF membrane flows deteriorate over time which steadily increases operating pressure to the point where the NF feed pumps cannot push water thru the membranes. The conservative estimates for life of these NF membranes are 5-7 years. The plant started in December 2014.Current projections (5/2020) show that the NF membranes should go another 2-3 years. In saying this in 2022 would be a conservative estimate for replacement. At the end of the NF life the high-pressure conditions can begin to increase rapidly so having the funds available to replace these NF membranes will be essential. We currently clean these NF Membranes every 3 months when operating pressures increase to the point of losing design flow thru the membranes. At the end of the life of the NF membranes the cleaning frequency increases substantially. Having this funding available when necessary will ensure the ability to provide the necessary volume of water for the daily needs of our customers. The project is included in the city's 2022-2026 Capital Improvement Program (CIP). As of February 10, 2022, further details regarding design and construction have not been identified.
