About this file
This document is a set of waterline construction plans prepared for the Tualatin Valley Water District (TVWD) by 3J Consulting, Inc., with survey work by PACE Engineers, Inc., for Project 100315 on NW Walker Road between NW 185th Avenue and NW 173rd Avenue in Washington County, Oregon. The plans consist of 22 sheets detailing the design and installation of approximately 1,000 linear feet of new 12-inch and 8-inch ductile iron water mains, including associated fittings, valves, blowoffs, and tracer wire systems. The waterline project includes connection points to existing TVWD infrastructure, removal and abandonment of existing pipe sections, and coordination with concurrent City of Beaverton waterline construction. The contractor must provide a minimum five-day notice prior to beginning construction and coordinate service shutdowns with at least two weeks' advance notice. All construction must comply with TVWD Standards and Details and the 2021 Oregon Standard Specifications for Construction, with hydrostatic testing at 150 PSI, disinfection per Oregon Health Authority guidelines, and bacteriological sampling required before placing the system into service.
Material specifications require Class 52 ductile iron pipe with cement mortar lining, zinc coating, and asphalt seal coating, with all joints restrained using approved boltless restraint systems such as Flex-Ring or TR Flex. The pipe must be installed with 8-mil polyethylene wrap encasement and tracer wire for lines 12 inches or larger or deeper than 5 feet. All materials must be new domestic manufacture with documentation proving United States origin, with no rebuilt or foreign-manufactured materials permitted. The contractor is solely responsible for pipeline placement methodology, which must be submitted for approval prior to construction, and must maintain all alignment stakes, slope stakes, and grades necessary for proper installation. Connections to existing infrastructure cannot be made until required inspections and tests are completed and approved by TVWD, with valve operations restricted to TVWD staff only. The contractor must dispose of water used for testing and disinfection in accordance with applicable federal, state, and local regulations, including Clean Water Services discharge permit requirements and DEQ mandates for chlorine residual reduction.

BASIS OF BEARING:
South 66°27'36" east 819.64 feet between monument number 209 and monument number 221 per Washington County survey records.
ELEVATION DATUM
Elevation of 216.375 feet based on NGVD 29/47, Washington County Benchmark No.924.
