MEMORANDUM

TO: Board of Directors DATE: November 11, 2015 FROM: Don Bunts SUBJECT: Consideration and Action on Construction Services for the Plano Lift Station

Force Main Relocation and Bridge, C-1256.06 SUMMARY:

Issue: The District is nearing completion of the Plano Lift Station Force Main Relocation and Bridge project. As a component of this project the District had previously agreed in concept with Rancho Santa Margarita Landscape & Recreation Corporation (SAMLARC) to design a small capacity sewage lift station and force main to service the bathroom facilities at the Canada Vista Park (CVP). Recommendation: 1) Approve Change Order No. 1 to Norman A. Olsson

Construction Inc. (OCI) for $134,610 to construct the CVP Lift Station facilities; 2) Authorize staff to establish an agreement with SAMLARC for reimbursement of the capital and maintenance costs for the CVP Lift Station.

Fiscal Impact: Funding for the Plano Lift Station Force Main Relocation project is included in the Capital Replacement Reserve portion of the Fiscal Year 2014/15 Five Year Capital Improvement Program. The construction costs for the CVP Lift Station will be borne entirely by SAMLARC. Previously Related Action: In October, 2014 the Board awarded the construction services contract for the Plano Lift Station Force Main Relocation and Bridge to OCI. Anticipated Board Action Date: It is anticipated that this item will be brought to the entire Board for consideration on November 20, 2015. Adherence to Policy:

• This project is consistent with the District’s mission o “… to collect and treat wastewater to protect the environment and public health.” o “Provide a high level of service with maximum cost effectiveness.” o “Plan for the future to guarantee a safe and sufficient water supply and

wastewater reclamation service.”

• This project is consistent with the District’s Purchasing Policy and Procedures. This proposed project is consistent with the District's Purchasing Policy because it: was competitively bid was identified in the current fiscal year’s CIP and is more than $49,999 and requires Board approval.

Page 6

Board of Directors November 11, 2015 Page 2

DISCUSSION: The construction of the Plano Lift Station Force Main Relocation and Bridge project involved extensive use of the CVP grounds. In exchange for temporary use and access through the CVP site, installation of a small diameter force main (portion) and a drain line for future wastewater service for the CVP restroom facility has been requested by SAMLARC. A main MOU aspiration expressed by SAMLARC is the District design of a small sewer lift station to serve the CVP restroom building. Prior to the implementation of the proposed CVP Lift Station, the park bathroom facility drains to a subterranean holding tank, and has to be manually pumped out at sporadic intervals. The new lift station improvement will allow for the bathroom facilities to be drained and automatically pumped across the newly constructed bridge and delivered to the Plano Lift Station, whereby the flows will be entered into the Districts overall collection system. The costs of construction, operations and maintenance, and the necessary easements are to be borne by SAMLARC as stipulated in the forthcoming agreement. The legal cost of easement preparation is estimated at $6,000.00, and is not included in the $134,610 of construction costs. Below is an excerpt from the revised project plans showing an overhead view of the CVP Lift Station and appurtenances. It includes a prepacked mechanical lift station, inlet and outlet piping, electrical power and controls, and an enhanced programmable logic controller (PLC) in accordance with District standards.

MEMORANDUM TO: Board of Directors DATE: November 11, 2015 FROM: Don Bunts/Tricia Butler SUBJECT: Consideration and Action on Grant of Easement to San Diego Gas and Electric for

the Esencia Recycled Water Pump Station Facility in the Esencia Planned Community, Contract C-1767F

SUMMARY

Issue: The District proposes to grant an easement to San Diego Gas and Electric Company (SDG&E) over a District land parcel where the Esencia Recycled Water Pump Station (RWPS) is proposed for construction. One parcels for the Esencia LS site was deeded to the District by Rancho Mission Viejo (RMV) in October of 2015 when Tract Map No. 17562 was recorded. Board authorization is required prior to granting an easement to SDG&E on District property for on-site electrical improvements. After District execution, SDG&E will need to record the easement document before electrical service to the new facility can be provided.

Recommendation: Approve grant of easement to SDG&E for the subject facility.

Fiscal Impact: None

Previously Related Action: On September 18th, the Board approved pre-purchase of pumps for the Esencia RWPS. In October 2015 the EOC recommended approval of the construction contract at the November 20th, 2015 Board Meeting, for the Esencia RWPS pending receipt of responsive, responsible bids. Anticipated Board Action Date: It is anticipated that this item will be brought to the entire Board for consideration on December 18, 2015.

Adherence to Policy:

• This project is consistent with the District’s mission o “Provide a high level of service with maximum cost effectiveness.” o “Plan for the future to guarantee a safe and sufficient water supply and wastewater

reclamation service.”

Page 9

Board of Directors November 11, 2015 Page 2 DISCUSSION: Bids for the Esencia Recycled Water Pump Station (RWPS) are due November 10, 2015. Award of a construction contract is anticipated for approval at the Board meeting of November 20, 2015. When placed in operation, the facility will convey recycled water to the Tesoro Zone B Recycled Water Reservoir to serve the Esencia community (previously referred to as Ranch Planning Area 2) and future Ranch Planning Area 3 and portions of Planning Area 4. The site is located at 28757 Chiquita Canyon Drive, San Juan Capistrano, CA 92675 as indicated on the map attached as Exhibit A. As part of the Tract No. 17562 Map recordation process that dedicated most public streets and subdivided residential land parcels within the Esencia community, RMV granted land parcels described as Lot 63 (0.237 acres) to the District. Exhibit B is a portion of Tract No. 17562 Map (Sheet 26 of 27) and shows the location of the Esencia RWPS site (Lot 63). To serve the electrical power needs for the new recycled water pumps and other associated equipment, SDG&E required that a transformer be installed on Lot 63. If granted by the District, SDG&E is anticipated to execute and record the easement during January or February 2016 to allow for the installation of electrical service. District granting of an access and maintenance easement to SDG&E over Lot 63 is recommended by staff. Facility Summary The Esencia RWPS site is located north of Chiquita Canyon Drive. In the initial phase, recycled water stored in Middle Chiquita Zone A Reservoir will be conveyed to the Tesoro Zone B Reservoir using the Esencia RWPS. In the second phase of operation, recycled water stored in Trampas Reservoir serving Zone A will be conveyed to the Tesoro Zone B Reservoir using the Esencia RWPS. Ultimately, the Esencia RWPS will convey recycled water from the Trampas Reservoir to both the Tesoro Zone B Reservoir and a future Zone B Reservoir in the Rancho Mission Viejo Planning Area 3. The award of the construction contract is anticipated in November 2015. The Contractor will install a soldier pile retaining wall and complete final grading of the site. A block structure will be constructed consisting of a pump room and an electrical/control room. The pre-ordered pumps are scheduled to arrive in May 2016. The facility is scheduled to be operational in September 2016 with final completion in October 2016.

MEMORANDUM TO: Board of Directors DATE: November 11, 2015 FROM: Don Bunts SUBJECT: Consideration and Action on Construction Services for South County Pipeline

Service Connection No. 6, Contract C-1771B SUMMARY

Issue: Residential construction activity within Rancho Mission Viejo’s (RMV) Esencia Village (previously referred to as Ranch Plan Planning Area 2) has been ongoing since September 2014. On a temporary basis, domestic water service to lower elevation tract areas within the Esencia development has been supplied from a City of San Juan Capistrano flow control facility (FCF) located near the intersection of Ortega Highway and Antonio Parkway. Construction plans have been prepared for a new permanent FCF designated as SC-6. SC-6 is located on the southern end of Esencia near Cow Camp Road and will supply domestic water from the South County Pipeline to two Esencia service zones. SC-6 will also be the primary source for Sendero Village and future Ranch Plan communities.

Recommendation: Award contract to SSC, Pascal & Ludwig Constructors, SS Mechanical,

Olsson Construction, or Schuler Construction in the amount of $2,2xx,000.

Fiscal Impact: Funding for construction is proposed from recently approved Esencia Village Community Facility District bonds issued by the County of Orange (No. 2015-01).

Previously Related Action: The District authorized an engineering design and construction

support services contract for the Esencia Lift Station and for the SC-6 FCF in February 2014. In April 2015, the District awarded a construction contract for the Esencia Lift Station that is now being built on the easterly half of the combined use site.

Anticipated Board Action Date: It is anticipated that this item will be brought to the entire Board for consideration on January 6, 2016. Adherence to Policy:

• This project is consistent with the District’s mission: o “Provide a high level of service with maximum cost effectiveness.” o “Plan for the future to guarantee a safe and sufficient water supply and wastewater

reclamation service.” • This project is consistent with the District’s Purchasing Policy and Procedures,

Section VI.

Page 13

Board of Directors November 11, 2015 Page 2

• This proposed project is consistent with the District's Purchasing Policy because it: was competitively bid, was identified in the current fiscal year’s CIP, is more than $49,999 and requires Board approval (Exhibit 1, a, (1))

DISCUSSION:

The proposed SC-6 FCF is located at the lower end of Esencia and off of future Cow Camp Road (CCR) as shown on the location map attached as Exhibit A. Completion of the SC-6 FCF (also referred to as a Turnout facility) is intended to finish a small electrical systems building recently erected to house motor control center and instrumentation controls for the Esencia Lift Station facility (still under construction). Domestic water is to be supplied from a new connection to the South County Pipeline (SCP) and a shut-down of the SCP is planned in late winter / early spring in 2016. The proposed SCP connection piping is generally shown in the diagram below for reference that was excerpted from the SC-6 construction plans:

The SCP generally operates with an average High Water Level (HWL) of approximately 860 feet (elevation above mean sea level - eamsl). In order to serve the lower Zone I (650 feet HGL eamsl) demands within the Esencia and Sendero Village developments, pressure reduction equipment on one branch of piping within SC-6 is required.

Page 14

Board of Directors November 11, 2015 Page 3

Higher elevation areas within Esencia Village and the future PA 3 area will be supplied from the Ranch Plan Zone II system (830-feet HGL eamsl). Zone II demands will be delivered through SC-6 with only minor valve controls that limit the discharge flow rate. This is to minimize pressure loss so the proposed new Tesoro Zone II reservoir (located north of the Chiquita WRP plant) can be filled without pumping when community demands are not consuming the flow rate coming out of SC-6. New Zone I and Zone II pipelines have recently been completed in CCR and also within the Esencia development area but RMV needs to complete a last Zone II pipeline section within the northern most area of Esencia.

A 2014 Plan of Works document specifically prepared for Esencia area outlined the Maximum Day DW demands for Zone I and II generated from Sendero Village, Esencia Village and from future PA-3 through PA 5 area. The total projected flow is approximately 19.3 cubic feet per second (cfs) as described in the table below.

FUNDING Construction funding for the SD-6 s project is from Project Code 3A7 as listed in the Improvement District No. 4C portion of the District’s Fiscal Year 2015/2016 Capital Improvement Program. Funding is proposed to be partially from the proceeds of a Community Facility District bond sale that was recently completed in mid-2015 by the County of Orange.

MEMORANDUM TO: Engineering and Operations Board Committee DATE: November 11, 2015 FROM: Don Bunts/Tricia Butler SUBJECT: Consideration and Action on Chiquita Water Reclamation Plant Screw Press

Installation and Grit Washer Replacement, Award of Construction Contract, C-1241T.002 and 1241T.006

SUMMARY

Issue: The existing belt filter presses and grit washer at the Chiquita Water Reclamation Plant (WRP) have reached the end of their service life. Newer technologies are available that provide more cost effective operation and that reduce the potential for odors to be emitted from the processes.

Recommendations: Approve the award of the construction contract for $xxx,xxx to install

two new screw presses and replace the existing grit washer. Fiscal Impact: Total project $xxx,xxx

Previously Related Action: In mid-2015, the Board approved pre-purchase of the screw

presses. In October 2015, the board approved pre-purchase of the grit washer and engineering services for electrical and structural design, as well as a bulk polymer storage tank and conveyor as long lead equipment required for the screw press installation. Anticipated Board Action Date: It is anticipated that this item will be brought to the entire Board for consideration in December 2015 or early January 2016. Adherence to Policy:

• This project is consistent with the District’s mission o “Provide a high level of service with maximum cost effectiveness.” o “Plan for the future to guarantee a safe and sufficient water supply and wastewater

reclamation service.” • This project is consistent with the District’s Purchasing Policy and Procedures

Page 17

Engineering and Operations Committee November 11, 2015 Page 2 DISCUSSION The existing Belt Filter Presses (BFPs) at the CWRP were installed with the initial plant construction in 1985. The two BFPs have reached the end of their service life and are costly to maintain. Over the years the cost of disposing of the dewatered biosolids has become significantly more expensive. One of the major components of this cost is the weight of the material (sludge) that must be disposed of offsite. The weight of the sludge can be decreased by reducing the amount of water in the “cake” which can only be accomplished by increasing the efficiency of the dewater process. Earlier in 2015, District staff evaluated options for dewatering equipment including pilot testing of equipment. Based on this evaluation, the Huber Screw Presses were recommended and approved by the Board for pre-purchase as a long lead item. Pre-purchase of a bulk polymer storage tank and dewatered sludge cake conveyor were also approved. The proposed layout of the equipment is shown in Figure 1:

Figure 1 - New Screw Press Layout

Engineering and Operations Committee November 11, 2015 Page 5 Pre-purchase of a new grit washer was approved in October 2015, and design work initiated for the installation of the grit washer. The layout of the new grit washer is shown in Figure 5.

Figure 5 - New Grit Washer installation

Page 21

Engineering and Operations Committee November 11, 2015 Page 6 The grit washer replacement will be included with the screw press installation. Construction requirements of both the screw press and grit washer are similar. Packaging the projects together should result in more competitive bids and savings in administration of fewer contracts. Both the grit washer replacement and the screw press installation will reduce the potential for odor emissions from the Chiquita Water Reclamation Plant. The screw presses enclose the dewatering process. Newer technology grit washing equipment such as the Huber grit washer selected for this project remove organics from the grit removed. Grit stored prior to disposal is clean and dry, compared to previous stored grit with organic, odor-emitting materials. In addition to the screw press and grit washer, installation of a tertiary filter overflow drain pipe is included in this design package. The CWRP has experienced overflow from the filter basins under certain abnormal operating conditions, which inundated and damaged pumps in an adjacent pump pit. An overflow pipe in the filter influent channel is proposed to convey overflow to the head of the plant while the filter overflow conditions are being addressed. This overflow facility will also serve future filtration units when the recycling capacity is expanded. A photo of the Filter Area is shown in Figure 6.

Figure 6 - Filter Chamber

District staff is managing the production of design plans and specifications, and completing the civil and mechanical work. Electrical and structural design is being completed by sub-consultants. The project is scheduled to advertise for bids in November, with construction contract award in December or early January. The engineer’s estimate for construction cost is $ xxx,xxx. Bid and construction services are proposed to be performed by District staff. FUNDING The proposed project is part of the Phase IV Chiquita WRP Expansion, Contract No. C00E28 in the current Capital Improvement Project budget, to be funded by future bond issue #4C for Chiquita.
