Gilbert, Director of Public Works C DATE: April 19, 1996 (Council Meeting 5-1-96) SUBJECT: Consider Authorizing Recordation of the Notice of Completion for the Installation of a Pump and Related Equipment for Water Well 13 at Arroyo Vista Community Park DISCUSSION A. Background 1. The property conveyed to the City by Urban West Communities for Arroyo Vista Community Park included two existing water wells used in the past to supply irrigation water to the agricultural uses on the property. Although the water extracted from these wells is high in Boron and thus not suitable for drinking, it was determined that this ground water could be used to provide irrigation water to the park. The design for the park called for the construction of an irrigation system supplied by these wells. 2. These water wells were in excess of forty (40) years old. Accordingly, the City Council authorized staff to proceed with a water well rehabilitation program which included the following improvements: - the removal, inspection and evaluation of Water Well #2; - based on that analysis, it was decided to replace Well #2 rather than attempt to rehabilitate it; - the destruction and capping of water well #2; - the replacement of the pump motor for Well #1 with a new 40 HP submersible pump; - the preparation of a design and the award of a construction contract for the drilling of a new Well #3; - the subject project to install the pump, piping and related equipment required to make Well #3 operational. 3 . In December of 1994 the City Council accepted the improvements and authorized the recordation of a Notice of Completion for the drilling of Water Well #3 at Arroyo Vista Community Park. 4. In September of 1995 the City Council approved the plans and specifications for the subject follow-up project to install the well pump and related equipment. Upon completion of the subject project, the water well rehabilitation program will be completed. avpwe118.cmp 000036 Arroyo Vista Community Park Well #3 Pump and Tie-In May 1996 Page 2 5. On December 20, 1995, the City Council awarded a contract for the subject project. That work is now completed. B. Purpose The primary purpose for using the on-site water wells is cost effectiveness. A comparison of the estimated cost of well water and domestic water is summarized as follows: Domestic Water City Water Description Service Costs ($) Well Costs ($) Calleguas Municipal Water 70 ,000 0 District Connection Fees Water Works District #1 19,000 0 Capital Connection fees Water meter installation 1,500 0 charges Water usage per year 30,000 1,000 Phase I (33 acres) Water usage per year 60,000 2 ,000 Total Park (69 acres) Water well maintenance 0 1,000 and operation (electrical energy, oil, etc. ) C. Project Description The subject project generally consists of the following: • installation of a pump in the newly drilled Well #3 ; • installation of piping and the connection of Well #3 to the irrigation supply control facilities located at Well #1; • installation of electrical service and equipment; and, • installation of control systems. D. Project Status The construction of the subject project has been completed. The work has been tested and accepted. The upgrading of the irrigation supply system for Arroyo Vista Community Park has been completed. Through these wells, the park now has a primary and a back-up source of irrigation water, without the need of an expensive connection to the domestic water supply for the City. It is the intent of the Parks Maintenance staff to alternate the use of these two wells to assure that both are in good working order. avpwell8.c4 `mma+l Arroyo Vista Community Park Well #3 Pump and Tie-In May 1996 Page 3 E. Future Expansion of the Irrigation System Designs are now underway for the construction of two additions to the irrigation water system supplied by these wells. The first would extend the system to irrigate the turf area now being developed just east of the existing park improvements, which is to be used for youth football. The second will extend the irrigation system across the Arroyo Simi, inside the Arroyo Vista Community Park Pedestrian/Equestrian/Bicycle bridge to serve the north side of the bridge and Campesina Park. F. Fiscal Impact 1. Total Contract Cost Summary: The total final construction costs for the subject project are summarized as follows: Bid Amount $38,165.00 Quantity Adjustment $ 0.00 Sub-Total $38,165.00 Change Order #1 (security enclosure) $ 1,896.00 Change Order #2 (meter access door) $ 329.00 Change Order #3 (install gauge & flange) $ 497.85 Total $40,887.85 2. Total Project Cost Estimate: A summary of the total cost for both the well drilling project and the subject project for the installation of the pump and related equipment, is as follows: Element Prior Years ($1 FY 1995/96 ($1 Total ($1 Well Drilling Project Design 17,000 17,000 Construction 42,800 42,800 Inspection 13,620 13,620 Sub-Total 73,420 0 73,420 Subject Pulp Installation & Hook-up Project Design 6,200 700 6,900 Construction 40,889 40,889 Constr.
