FINANCIAL STATEMENT <br /> Funding for the project will be paid through an eight year loan from JP Morgan Chase and <br /> reimbursed by the Water Fund City staff have been working with the City's bank, JP <br /> Morgan Chase, to secure a loan JP Morgan Chase submitted a term sheet with a <br /> proposed interest rate of 2 00% for an 8-year loan which translates into annual payments <br /> of between $544,840 to $1,165,765 and total interest expense of $578,983 In addition, <br /> the City would have to pay legal expenses associated with preparing and reviewing the <br /> loan documents Staff will prepare a separate item to approve a loan with JP Morgan <br /> Chase for City Council consideration at a future City Council meeting <br /> BACKGROUND <br /> The base Pleasanton-DERWA agreement was executed November 2013 with <br /> Amendment #1 (maintaining the existing Val Vista Park connection) executed in <br /> September 2015 Section 5 3 of the base Pleasanton-DERWA agreement outlines the <br /> process and conditions for Pleasanton's recently completed DERWA expansion project, <br /> the Sixth Filter, as well as the process and conditions for future facilities expansion <br /> project(s) at the DERWA Recycled Water treatment plant When the base Pleasanton- <br /> DERWA agreement was executed, the DERWA plant design capacity (pre-sixth filter) <br /> was estimated to be 9 7 mgd, and the sixth filter was expected to expand that capacity <br /> by 1 9 mgd to a total of 11 6 mgd The presumption at that time was that additional <br /> treatment capacity could be created by future facilities expansion projects which would <br /> build more filters in a second, yet to be constructed, filter bank Unfortunately, although <br /> the design capacity of the sixth filter targeted a total plant design treatment capacity of <br /> 11 6 mgd, it was determined that the plant was only able to deliver 8 mgd due to the <br /> constantly high solids content of the plant influent coming from the DSRSD treatment <br /> plant, falling short of the design capacity by 3 6 mgd <br /> The underperformance of the DERWA plant, even with the sixth filter, brought into <br /> question the necessity of constructing more filters to meet future targeted RW demands <br /> as envisioned by the base Pleasanton-DERWA agreement, as well as bringing to light <br /> the fact that the average secondary influent being imported from DSRSD's secondary <br /> treatment plant into the DERWA RW plant had a much higher concentration of suspended <br /> solids than originally expected, which severely hampered filter performance <br /> To address the filter performance, DSRSD contracted with Carollo Engineers to design <br /> the expansion project In order to boost the existing filters' as well as future yet to be <br /> constructed filters' performance to or beyond their intended design capacities, a series of <br /> stakeholder design workshops including Pleasanton Utilities staff was held, and it was <br /> mutually agreed that the planned facility expansion should incorporate a ballasted <br /> flocculation process (proprietary name Actiflo) at the head of the plant, prior to the <br /> filtration treatment train The Actiflo is an industry proven process for removing high <br /> volumes of solids from the influent before directing it through the filtration process <br /> With the Actiflo's significantly reducing solids in the pre-filter influent, the treatment <br /> capacity performance of each of the existing six filters will increase from 1 4 mgd to a <br /> minimum design capacity of approximately 2 7 mgd per filter, providing for a total plant <br /> capacity of 16 2 mgd Combined with the other elements of the planned expansion, <br /> Pleasanton's share of the DERWA RW production volume will be increased to <br /> Page 2 of 4 <br />
