FOR
USCG STA Milford Haven Water Treatment Plant Mechanical Overhaul & Equipment Replacement

1.0 GENERAL

Background
The work consists of providing all labor, materials, tools, supervision, and equipment needed to repair and replace equipment at the Potable Water Treatment Plant located at USCG STATION MILFORD HAVEN, 63 MILL POINT ROAD, HUDGINS, VA 23067.
The station water treatment plant currently has five main issues that need correction:
1. Sand Bed Filter: The sand filter has surface algae and plant growth, and the basin seams are leaking sand. This has dropped the sand bed below the required 12-inch depth.
2. Booster Pump: The current continuous-run distribution pump is worn out and runs hot, damaging the PVC pipe connected to it. It needs to be replaced with a brand-new identical pump, and the heat-damaged piping next to it needs replacement.
3. Water Softener & Pre-Filter: The plant only has one water softener and one prefilter. If it goes down or regenerates, the station loses water treatment. A second softener and pre-filter are needed for backup.
4. Water Storage Tank: The clean water storage tank does not have a bottom drain valve, making it difficult to drain and clean out iron sludge and sediment. 5. Well Sump Pump: The sump pump in the well pit only works when turned on manually. It needs an automatic float switch and timer to flush automatically on schedule.

Scope
Furnish and deliver all equipment, valves, piping, media, and controls as specified herein. A SITE VISIT SHALL BE REQUIRED to USCG STA Milford Haven, 63 MILL POINT ROAD, HUDGINS, VA 23067, prior to bid submission to field-verify all dimensions, existing electrical services, piping runs, and equipment clearances. The Contractor shall:
- Clean out all growth from the sand filter bed, reseal the basin seams with drinkingwater-safe sealant, and add clean filter sand to a depth of at least 12 inches. - Remove the worn continuous-run booster pump and heat-damaged piping, and install one (1) new identical like-kind continuous-run pump. - Install two (2) new commercial water softeners that alternate automatically (one running, one in standby), along with dual pre-filters.
- Cut in and install a 2-inch bottom drain and cleanout valve on the water storage tank with a quick-connect hose coupling and an air-gapped drain line. - Repair and rewire the well sump pump with an automatic float switch and timer control box.
- Disinfect, pressure test, and test the water through an accredited lab before
