FROM: James D. Herberg, General Manager, Orange County Sanitation District
Originator: Rob Thompson, Director of Engineering
SUBJECT: AMENDMENT TO THE 1972 WASTE WATER INTERCEPTOR CAPACITY AGREEMENT DATED MAY 12, 1972 TO MODIFY THE COST SHARING REACH DEFINITIONS FOR THE NEW PIPING SEGMENTS
RECOMMENDATION
Recommend Board Approval of the second amendment to the Wastewater Interceptor Capacity Agreement dated May 12, 1972 between County Sanitation District No. 2 of Orange County and Chino
Basin Municipal Water District to modify the cost sharing reach designations for the newly installed pipe and metering station.
BACKGROUND
Santa Ana Watershed Project Authority (SAWPA) and the Orange County Sanitation District (Sanitation District) have been working cooperatively with the County of Orange to realign the
Santa Ana River Interceptor pipe from the Riverside/Orange County line through Anaheim. The new pipe alignment is different than the old pipe with different points for inflow from
the local systems.
The original agreement called for cost sharing percentages that were based on flow capacity splits owned by each party in each reach. A reach is defined as a portion or segment of the
proposed Santa Ana River Interceptor, selected for cost allocation purposes. The agreement defined eight individual reaches. The reaches defined as reaches 5, 6, 7 and 8 in the original
agreement were replaced by the County of Orange project. The proposed amendment redefines the cost split for future capital and maintenance costs for the new pipeline using the same
capacity utilization methodology. Generally, SAWPA will pay the on-going capital and maintenance costs at the percentage of their 30 mgd flow capacity divided by the pipe capacity.
The upcoming rock removal project cost split will not be effected by this new reach definition and cost split, as it is related to the pipe realignment project and will follow the project
76%/24% split.
RELEVANT STANDARDS
Work cooperatively with other agencies.
Protect the water quality of the Orange County water aquifer.
Maintain a proactive asset management program
PROBLEM
The Santa Ana River Interceptor pipeline has been realigned. The cost sharing proportions defined in the old agreement need to be adjusted to match the new pipe reaches.
PROPOSED SOLUTION
Amend the 1972 agreement to reflect the new pipe alignment.
TIMING CONCERNS
This administrative change should be completed as soon as possible to clearly define the financial responsibilities of both parties.
RAMIFICATIONS OF NOT TAKING ACTION
Lack of contractual clarity may cause unnecessary friction between agencies.
