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.
