DESCRIPTION
This project resulted in conceptual design drawings for pump exchange facilities on the Wenatchee River near Dryden serving the Icicle and Peshastin Irrigation District, along with an opinion of probable costs. This project has evolved from the original concept of a pump station and delivery pipeline that would supply water for irrigation to the Peshastin Irrigation Canal during late summer only to a new, expanded concept that includes pump exchange facilities at one or more locations on the Wenatchee River and improvements to the IPID delivery system that will enable delivery of water to both the Peshastin Canal and portions of the Icicle Canal throughout the full irrigation season. This concept would result in the complete elimination of the Peshastin Creek Diversion to the Peshastin Canal and expanded reduction of diversions from Icicle Creek to the Icicle Canal. The uploaded memorandum and conceptual designs summarize this pump exchange concept and provide conceptual design and cost estimates for one of the pump station locations at Dryden. While the willingness of the landowner at the pump station location changed throughout the duration of this project, IPID and Chelan County will be re-engaging discussions with this landowner in the coming months to discuss the expanded pump exchange concept. An alternatives analysis for the other potential pump station locations and design are being completed under a separate grant (19-1479). This project is being designed to enable p
Work completed under this grant include conceptual design drawings for the Dryden pump exchange facilities and an opinion of probable costs. The conceptual design includes the following key facilities:
1) Intake Facilities including intake screen, intake structure, and intake pipeline;
2) Wet Well and Pump Station including wet well, pump station building, pumps, valves, fittings and other appurtenances;
3) Discharge Pipeline; and
4) Delivery to Canal
These conceptual design and cost estimates are included in the project memorandum uploaded.
