Director Memorandum 19-017
Date: February 5, 2019
Prepared By: Matthew Porras, Implementation Manager
Subject: Ratification of the Purchase of Pipe Materials for the Calimesa Lakes
Recharge Study
Recommendation: That the Board ratifies the purchase of pipeline materials for the
Calimesa Lakes Recharge Study for a sum not to exceed $24,375.
As a part of the Calimesa Lakes project,
the District has contracted with Geoscience
who will be conducting recharge testing by
discharging water into constructed basins
with the point of discharge depicted in this
conceptual drawing. The testing is
scheduled to last 6-8 weeks. The lead time
on the pipe and fittings is estimated at 3
weeks.
The water supply source for the recharge
testing will be from a fire hydrant within the
Summerwind Trails development. The
pipeline path is estimated to be just under
1,400 linear feet.
As a part of the Geoscience contract, the District is responsible to furnish and install the temporary
supply piping. The temporary piping can be either rented or purchased. Based on discussions
at during the Board Workshop held on January 8, 2019 [Workshop Memorandum 19-013], and
January 29, 2019 [Workshop Memorandum 19-029], District staff recommended purchasing the
pipe and fittings for this project due to the future cost savings when compared to a second rental.
The costs associated with the rental option include the consideration of the rental cycle of 28 days
and the estimated timeframe of the project of 6-8 weeks totaling at least two rental cycles. If the
project exceeds the estimated timeframe, the rental cost will quickly exceed the purchase cost.
Additionally, having this pipe and fittings on hand will improve the District’s response time for
emergency response and future use of this pipe material.
Financial Consideration
Funding for this study will be paid from the Sewer Fund, [GL Account #03-5-02-51003]. There is
sufficient funding available.
