3. SCOPE

3.1 PUMP REPLACEMENT:

COPPER AND COPPER LIKE MATERIALS SHALL NOT BE USED IN THE

INSTALLATION OR OPERATION THAT MAY COMES IN DIRECT CONTACT

WITH WATER THAT IS TO BE DELIVERED TO THE HATCHERY AS THIS IS

DETRIMENTAL TO FISH.

Disconnect and pull existing 4” pipe (approximately 210 +/- feet), pump, and motor; remove existing 40 HP Wilo/ Goulds model: 7CHC submersible pump S/N: SC7WAD6SA and motor: Franklin Model: 2366178125 S/N: 13G19- 29- 06016A 40 HP. 50/60 hz, 460 vac, thee phase 61.6 Service Factor Amps. This is controlled by a Yaskawa VFD model cimr-pu4a0072faa; Input: AC, 3 phase 380-480 v 50/60 hz 71 amps. Output: AC, 3 phase 0-480v 0-400 hz. 72 amps. (Yaskawa VFD is to remain). Pump and motor is to be pulled from a 14” diameter well casing. Well house has a sky light in roof directly over the wellhead, which may be removed and used to pull/lift the pump and water piping. Turn existing submersible pump over to hatchery. Properly dispose of, off-site, old material not detailed to be turned over to facility at an approved disposal site. Refer to the 2014 Final Pump Test document in the attachments for existing pump installation details.

All electrical work shall comply with appropriate articles and sections of the 2023National Electric Code (2023NEC).

Before any “on site” demolition is started, the hatchery construction inspector (CI) shall demonstrate to the contractor that the radio-link control communication works and properly modulates the pump flows. The CI shall document the demonstration, and both the contractor and the hatchery CI, shall sign and date that the existing radio-link is fully functional before starting any demolition.

Disconnect, remove, and turn old electrical cable over to SMARC personnel for disposal.

Install approximately 225 linear feet of new UL-Rated, three wire cable #4 AWG with ground wire cable for wet location used for submersible wells from new pump motor to existing motor starter/controller. Reuse existing electrical raceway system outside well. Wire size determination may require a site visit to verify.

Contractor shall ensure well pump motor operates with existing variable frequency drive.

3.2 WELLHEAD REPLACEMENT:

System well head: Contractor shall remove existing equipment and turn over to SMARC personnel for disposal. As well head looks like a custom fabricated unit, Contractor is advised to conduct a site visit to verify size, dimensions, securement and installation.

Contractor shall install and secure new well head and accessories which shall include:

A ¾”water supply point on the elbow with a threaded ball valve to attach instrumentation and collect water samples, ¾”water return with ball valve on platform , air admittance port on platform, eyebolts to assist in lifting operations and replace corroded nut and bolt anchors.

Safeguard all supporting electrical equipment to prevent damage from water or movement of equipment. All electrical cables and wiring shall be protected from damage that may occur during movement and installation of new equipment.

4. EXISTING SITE CONDITIONS

Work areas shall be roped off to alert unauthorized personnel to work in progress. Jobsite is located within an easement on private property and work shall be relegated within proximity of the project site. Gates shall be closed at all times to prevent livestock from escaping.
