PERFORMANCE WORK STATEMENT

C-44 Cont. 2 Reservoir: Toe Trench System Pre-Inspection, Cleaning and Post Inspection

1. GENERAL INFORMATION

1.1 Description of Services: This is a non-personal services contract to video inspect, clean out and video inspect the C-44 Reservoir’s Toe Trench Drainage (TTD) System. The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items to perform all services as defined in this Performance Work Statement.

1.2 Background: The TTD system is located at the downstream toe of the embankment and generally runs parallel to the embankment and reservoir perimeter canals. The TTD system is comprised of 4 main materials; drain sand, drain gravel, dual wall HDPE perforated pipe and geotextile. The reservoir is currently authorized to operate between a 3 ft and 10 ft pool. In the last 6-8 months, the reservoir pool has been between 3 ft and 5.5 ft. Along its more than 48,600 feet of HDPE perforated drainpipe, manholes are situated every 800 to 1100 feet of pipe, with a total of 56 manholes (Attachment A for locations).

Each manhole contains three pipes. Pipes within the TTD system, which run parallel to the embankment and canal, are perforated, and have an invert of El. 19 Ft. NAVD88. These pipes, which are submerged, transport any collected groundwater into the manholes. The third pipe in each manhole rests at a higher elevation (invert El. 20 ft. NAVD88). This pipe runs perpendicular to the embankment, is partially submerged, and is not perforated. The purpose of this pipe is to divert groundwater collected by the perforated pipes and drain from the manholes to the perimeter canal. The 12 – inch solid wall outfall pipe slopes downward from the manhole to an invert elevation of 19 ft. NAVD88 at the discharge point

(perimeter canal end wall).

The TTD system is designed to collect, filter, and transport through-foundation seepage/groundwater to the perimeter canals and has been operating since January 2022Dissolved solids in the groundwater, mainly iron, are present, and are accumulating in the TTD system (commonly referred to as ochre). The iron content of the groundwater is also apparent by the rusty reddish-brown color of the water in the perimeter canals.

The TTD system is comprised of the following components.

• Perforated dual wall 12-inch diameter HDPE pipe with drilled 5/16-inch perforations spaced evenly along its circumference.

• A two-stage filter composed of a drain sand and a No.57 gravel.

• A Type 1 non-woven geotextile fabric wrapped around the No. 57 gravel.

• 4 ft. inside diameter manholes

• Dual wall 12-inch diameter pipe HDPE pipe, non-perforated (manholes to perimeter canal)

• Concrete end walls along the perimeter canal.
