City of Angels Water Master Plan

Executive Summary

Angels WMP ES-2 MTB020401 July 2013 n:\mtb020401\documents\_water master plan\final\0713 mp.docx

1. Addressing regulatory concerns (Phase 1A)

2. Improving reliability by providing operational redundancy (Phase 1B)

3. Replacing aging infrastructure (Phase 1C)

4. Providing capacity for future development (Phase 2A)

The distribution system CIP was prioritized based on the following, in descending order of importance:

1. Providing required fire flow for existing demands (Phase 1A)

2. Meeting hydraulic performance criteria for existing demands (Phase 1B)

3. Providing required fire flow for future (buildout) demands (Phase 2A)

4. Meeting hydraulic performance criteria for future (buildout) demands (Phase 2B)

The total CIP cost is approximately $24.3 million, with an average annualized cost of $1.22 million. Comparing the projected CIP costs to recent City budgets (e.g., FY 2011-12 CIP budget for water of $260,000) indicates that additional revenues will be needed to adequately fund the recommended CIP projects. Included as recommended CIP projects are water rate and connection fee studies to better assist with determining appropriate project financing.

TABLE 2-1 CITY OF ANGELS WATER MASTER PLAN

SUMMARY OF RECOMMENDED PROJECTS IN THE 2011 WATER AUDIT

Project Number Project Description Rationale Status

WTP Projects

1 Construct Settling Ponds and Discharge Backwash Water Properly

Construct settling ponds. Recycle backwash water through headworks, obtain discharge permit, or discharge to wastewater system.

Required for regulatory compliance. Backwash water is currently being discharged without a permit.

Incomplete. Addressed in this Master Plan.

2 Implement Redundancy During Filter Backwash

Modify system so that at least one filter is on-line during backwashing.

Improves reliability. Allows water treatment to continue through backwash procedures, eliminating 2.75 hour shutdowns.


3 Pursue Emergency Alternative Water Supply

Pursue alternative options for providing emergency water supply in event that flume system is damaged.

Necessary to provide redundancy if flume system is compromised.


4 Construct Second Storage Tank

Construct a new 2.0 MG tank at one of three proposed locations.

Needed to meet future maximum day scenarios. Improve system reliability and security.


5 Address Post-Storm Turbidity Shutdowns

Option A: Investigate whether second sedimentation basin would prevent shutdowns. Option B: Investigate feasibility of pre-filtration or other process to make high turbidity water usable.

Necessary to improve reliability after storms. If Option A is feasible, it would also improve redundancy.


6 Add Fourth Filter Add fourth mixed-media filter to provide additional capacity at WTP.

Provide additional redundancy. Needed to accommodate future growth.





TABLE 2-1 (Cont.) CITY OF ANGELS WATER MASTER PLAN



Distribution System Projects

7 Complete an Inventory of the Distribution System

Complete an inventory of all pipes, valves, and hydrants within the system and incorporate into geographical information systems (GIS).

Necessary to allow the City to make accurate decisions in planning and construction. Needed to create hydraulic model.

Completed as part of this Master Plan. See Chapter 8.

8 Develop a Hydraulic Pipe Network Model

Develop a model of the system including the WTP, storage tank, and distribution system.

Can be used to analyze the system for compliance, make decisions, prioritize projects, and plan for future development.


9 Identify and Prioritize Infrastructure Upgrades using Hydraulic Model

Use the results of the model to identify and prioritize infrastructure upgrades.

Hydraulic model provides a tool for assessing system needs.


10 Assess Distribution System Compliance using Hydraulic Model

Use the results of the model to assess whether regulations are being met.

Provides a way for the City to demonstrate compliance with certain regulations.


11 Add Second Water Main from WTP to City

Add 18-inch pipeline parallel to the existing pipeline.

Necessary for redundancy and reliability. The existing pipeline is old and a major system weakness.


12 Loop Dead Ends and Install Blowoff Assemblies

Where possible, loop dead ends. Otherwise install a blowoff assembly.

Will improve system reliability and water quality. Required for regulatory compliance.





TABLE 2-1 (Cont.) CITY OF ANGELS WATER MASTER PLAN



Water Quality Sampling Projects

13 Update Bacterial Sampling Plan

Revise City’s Bacterial Sampling Plan by 2012 (last updated in 2002).

State regulations require a minimum number of samples per month based on number of connections. Because the number of connections in the distribution system has increased, a minimum of six samples per month is now required rather than the five samples per month required in the 2002 plan. Regulations also require the plan be updated every 10 years.

Completed.

Administration and Planning Projects

14 Develop City Planning Criteria in Next Water Master Plan

Incorporate all related water codes into a list of criteria for future planning.

Useful planning tool for assessing criteria for future infrastructure and existing deficiencies.


15 Submit Permit Amendment Following Major Upgrades at WTP

Submit application for a permit amendment following major improvements at the WTP.

Necessary for compliance with regulations. Will be submitted concurrent with completion of design activities.

16 Update Operations and Maintenance Plan

Update the plan to reflect upgrades to the WTP.

Required by Water Supply Permit. Completed by City Engineer in May 2012.

17 Pursue Shortage Plan with UPA

City should work with UPA to develop a plan to allocate water to all users during a drought.

Essential to securing a reliable water supply and the ability to meet maximum day scenarios at all times.

Ongoing.

18 Develop an Alternative Supply for GHC Development

Explore options for alternative supplies for GHC.

Necessary to ensure that the entire water supply allocation from UPA is available for the City.

Ongoing.

19 Staffing Level Recommendation

Hire one full-time and one part-time staff member.

Current staffing levels are below other comparable water purveyors by approximately 20 percent.

Under consideration.

SP 1.5 1.5 a Existing and future conversion factors from the City Wastewater Master Plan [18].

OS and ROW land uses are excluded from the table and the development of a water demand factor because no water demands are assumed for these land uses. The PR-Golf land use is also excluded from the table because irrigation demands associated with GHC Golf Course were evaluated separately.

b Future conversion factors based on projected General Plan [1] densities. c Water demands are not anticipated for future WWTP areas. Potential increases in

water demands at the existing 18 ac WWTP site associated with future expansions are assumed to be met with Title 22 recycled water.

As shown in Table 5-12, future EWU conversion factors for RE and BAE are lower than existing EWU conversion factors. The existing EWU conversion factor for RE was based on an analysis of existing parcel sizes for areas with the RE land use designation [18]. The existing EWU conversion factor for BAE was based on an analysis of existing developed commercial parcel areas [18]. The future EWU conversion factors, including the factors for RE and BAE, are from the General Plan [1, 18].

A water demand factor of 255 gpd/EWU results from using the method described in this chapter. It should be noted that the water demand factor is based on an EWU, not per capita or per dwelling unit, and is to be used only with the EWU conversion factors presented in Table 5-12. For context, there are a total of 1,769 existing water meter connections in the City and a total of 3,387 existing EWUs as calculated in Table 5-13. The number of water meters is not comparable to the number of EWUs.

3. The settlement agreement clarifies issues relating to the ownership and operation of CCWD-owned/NCPA-operated facilities, UPA owned and operated facilities, and physical access to those respective facilities.

4. Neither party can, without prior written consent, use or occupy any property nor facilities owned by the other party, nor apply for a grant or loan that would require use of the other party’s water rights or facilities [26].

Because of CCWD’s contracts with NCPA, the water available for use within the Ebbetts Pass-Murphys-Angels area is limited to the following:

1. The water UPA is contractually entitled to under Attachment A. The water is supplied by NCPA but the entitlement is based upon UPA’s pre-1914 water rights in the North Fork of the Stanislaus River-Mill Creek-Angels Creek system.

2. The maximum volume of 8,000 AF that CCWD is allowed to divert for consumptive

purposes from the North Fork of the Stanislaus River system is subject to the following restrictions: a. The water must be diverted “from points upstream of the existing Mill Creek Tap

butterfly valve” and CCWD cannot “cause this water to directly or indirectly enter any of the PG&E Project facilities without prior written agreement from NCPA.”

b. Under State Water Resources Control Board (SWRCB) Order No. 97-05 issued in September 1997, CCWD has until December 1, 2015, to put the entire 8,000 AFY to full beneficial use. Failure to do so could result in a partial revocation of CCWD’s SWRCB water rights permits; i.e., that portion of the 8,000 AF not put to full beneficial use by December 1, 2015 … “Use It or Lose It” [27].

Because of the above 2015 permit deadline, CCWD and UPA agreed in the November 2009 settlement agreement to use their best efforts to negotiate an agreement by December 31, 2014, for CCWD to transfer water to UPA for consumptive use in the UPA, City, and/or UPUD service areas. The settlement agreement does not identify the amount of water to be transferred but it could be approximately 4,000 to 5,000 AFY. Such water would be in addition to the water delivered to UPA under Attachment A, which is further defined in the following sections [27]. In 1985, CCWD entered into a Revised Power Purchase Contract and the 1995 Restated Agreement with the NCPA wherein CCWD gave control of most of the water in the North Fork of the Stanislaus River system to NCPA for power generation at the Collierville Powerhouse. Excerpts from the Asset Sale Agreement By and Between PG&E and Calaveras County Water District, August 18, 1995 and the Assignment and Assumption Agreement between CCWD and UPA are included as Appendix F.

3. Potential Well Site C (Area 3) – DE suggests exploring this location for high potential due to the proximity of Mehrten Gravels in conjunction with limestone deposits. Yields are anticipated to be high; however, water quality concerns may be identified. To meet the water supply short fall, only one well may be necessary. Two wells highlighted during the DWR well log search were identified with yields over 100 gpm close to this location.

4. Potential Well Site D (Area 2) – This location was selected as a potential location if the City pursues water well drilling and permitting efforts with the City of Murphys. The site is located in proximity to high-yield wells identified during DWR well log review and in the preferred geology package of tertiary gravels and Mehrten Formation close to limestone.

Months with the lowest production can be correlated to the rainy season when irrigation demands are low. As shown in Table 6-2, the lowest monthly demands for 2007-2012 occurred from December through March, with an average winter monthly demand of 4.8 percent of yearly production. The 2007-2012 estimated non-potable demand for April through November is the additional percentage above the monthly 4.8 percent identified as the base potable water demand. The additional non-potable or irrigation demand in the summer months adds to approximately 43 percent (42.5 percent) of the annual demand. Using this factor, the estimate of non-potable demands for the City is summarized in Table 6-3.

If approximately 43 percent of the City’s water demands is non-potable, then the opportunity exists to provide recycled water for the majority of these uses. For comparison purposes, Table 6-6 displays the balance of supply vs. demand using only City potable water demands, but keeping the GHC Golf Course surface water diversions in place. In this scenario, an additional supply of 62 AFY is required at buildout.

EVALUATION CRITERIA FOR ALTERNATE WATER SUPPLY STRATEGIES

Evaluation Criteria Description Importance

Factor

Meet 10-year Projection Capacity to deliver 10-year projected demands. 1.0

Meet Buildout Projection Capacity to deliver buildout projected demands. 0.5

WTP Expansion Need to expand existing WTP. 0.5

Second WTP Need to construct second WTP. 1.0

Minimize Impact of a Single Point of Failure (Single Pipeline)

Level of redundancy in key transmission pipelines. 1.0

Provisions for Emergency Conditions (Failure of Upstream Conveyance)

Ability to tolerate interruptions in raw water supply. 0.7

Impact from Drought Potential reduction in supply due to drought. 0.7

Capital Cost Relative magnitude of capital investment. 1.0

Operational Cost Relative magnitude of annual operation and maintenance costs.

1.0

Ease of Implementation Number/complexity of agreements, permits, approvals required for implementation.

1.0

Coordinated with Other City Plans Consistency with other City master plans or programs. 0.5

In evaluating a strategy, a score of 1-5 was selected for each criterion. Lower scores reflected an inferior alternate while a score of 5 signified a superior strategy when considering a specific evaluation criteria. As an example, for the criterion, WTP Expansion, if the strategy required an expansion of the existing WTP, the strategy would be assigned a low score. In contrast, strategies that do not incorporate improvements to the existing WTP would receive a higher score. By then applying the importance factor to each criterion score, a weighted score could be calculated and aggregated to identify a preferred alternate. This process is summarized in Table 6-12.

Chapter 9: Recommended Improvements



DISTRIBUTION SYSTEM HYDRAULIC PERFORMANCE CRITERIA

Criteria Value Source

Minimum pressure – ADD 40 psi 2010 Improvement Standards [16]

Minimum pressure – MDD 35 psi Typical design standard

Minimum pressure – PHD 20 psi California Waterworks Standards [10]

Minimum pressure – fire flow plus MDD

20 psi 2010 Improvement Standards [16], California Waterworks Standards [10]

Maximum pressure at service connection

150 psi (PRV required at 80 psi)

2010 Improvement Standards [16]

Maximum velocity 8 fps (typical) 12 fps (short durations)

Typical design standards

Maximum head loss gradient 10 ft per 1,000 ft Typical design standard

Generally, the existing distribution network has sufficient capacity for buildout ADD and MDD demand conditions. However, under buildout PHD demand conditions, there are a number of areas that fail to meet the minimum pressure specified in Table 9-4 and the fire flow requirements identified previously in Table 8-7. Based on the hydraulic analyses, approximately 27,400 LF of existing distribution mains were identified for upsizing to facilitate buildout demands. Recommended distribution main improvements are summarized in Table 9-5 and presented in Figure 9-2. The remaining segments of the SR-49 Pipeline Replacement (from Stanislaus Street to Altaville Post Office), identified in Section 2.2, are included in the Golden Chain Highway 8-inch to 10-inch improvement (upsize) project. Phasing of distribution system improvements are suggested considering the following priorities:

a. Provide required fire flow for existing demands (Phase 1A) b. Meet hydraulic performance criteria for existing demands (Phase 1B) c. Provide required fire flow for future demands (Phase 2A) d. Meet hydraulic performance criteria for future demands (Phase 2B)
