1.1 DESCRIPTION

A. Lake Mead National recreation area is in need of multiple pumps and motors for the Katherine Landing water treatment Plant.

1. Two Pumps and motors are needed for the water intake barge. This intake barge is comprised of 2ea. vertical turbine pumps and 2ea. 25hp motors. These pumps and motors are a critical part of the water treatment process at KL as they provide all of the raw lake water to the water treatment facility. The existing pumps are approx. 15-20 years old and have so much corrosion from years of use that they are no longer viable candidates for rebuild.

2. One Pump is needed for the Clean in Place (CIP) system that is used to clean the filters every 24 hours. A major component of this system is the circulation pump that delivers the cleaning solution to filters. A new pump is needed. The existing pump is Goulds model 3196 MTi, 4x6-10H/6v.

B. The scope of work for this contract consists of:

1. Supply New pumps and Motors and seals

2. Deliver the equipment to Lake Mead National Recreation Area. Address to be provided.

C. The Contractor shall provide all materials to be purchased described in this specification. All materials shall be new and Contractor-furnished from outside the park.

The new pumps and motors must match performance and size of old pumps. New pumps must interface with existing electrical controls and plumbing assemblies.
