New Water Plan Using Old Pipeline on Tap at City, Supervisor Meet Wednesday

A proposal for using an existing pipeline along Mountain Street to move water from Devil’s Gate Reservoir to Eaton Wash Reservoir is set to be discussed by city officials and County Supervisor Kathryn Barger when they meet Wednesday morning.

The Pasadena City Council is scheduled to meet with Barger to review a number of issues at 8 a.m. in the City Hall Grand Conference Room S-038, 100 North Garfield Avenue.

The proposal, still in the conceptual stage according to Pasadena Department of Water and Power spokeswoman Margie Otto, represents the revival of an earlier one calling for pipeline construction along New York Drive in Altadena.

The pipeline was intended to increase water conservation by capturing stormwater behind Devil’s Gate Dam and shipping it to the Eaton Wash Spreading Grounds to recharge underground reservoirs there.

The plan also envisioned a later addition connecting the Arroyo Seco to the pipeline.

In Aug. 2017, Pasadena Now reported that said project was “on hold” while the County Department of Public Works re-prioritized things.

Otto said that project, “is not part of the current proposal because of feedback from Altadena residents.”

The difference is, “instead of constructing a new pipeline, we’re utilizing an existing one. It helps us meet our goals of figuring out how to capture and utilize the water that’s being gathered [through the County’s projects].”

Those projects include a pump from Devil’s Gate Reservoir that will feed the Arroyo Seco for the purpose of capturing water in 13 man-made spreading basins sited there.

The new proposal would require some infrastructure building, namely a connector between the Arroyo Seco and the proposed Mountain Street conduit.

The opportunity arises, according to Otto, because completion of the Orange Grove pipeline project allowed the City to re-purpose the one under Mountain Street.

“What the City is hoping to do is maintain L.A. County’s initial objective,” said Otto. “If the County’s goal is to sustain groundwater and find ways to recharge for all of the region to benefit, this proposal allows us to balance our local supply and make sure it’s re-distributed in the natural system both on the west and on the east side.”

The proposal’s acceptance is dependent on the County’s completion of the related projects and the Wednesday meeting represents a good chance to “align” things being handled at different levels of government.

County Public Works Department spokesman Kerjan Lee said they have received the proposal early in the week of March 18.

“L.A. County,” he said, “continues to look for opportunities to invest in its public infrastructure to provide a more sustainable local water supply.”
