미국 국토개발부는 4월 13일 공청회를 개최했다. 공청회는 캘리포니아 샌위킨 계곡에서 시행된 북부 골짜기 지방의 물 재사용 프로그램(NVRRWP)을 위한 환경 영향 평가 보고서 과정의 한 부분이다.

NVRRWP는 3번 처리된 재활용 폐수를 이용하여 계속 진행중인 캘리포니아 물 문제의 한 부분인 새크라멘토-샌호아킨 강 삼각주 남부 골짜기의 측면 서쪽지역의 가뭄을 해결하기 위해 설계됐다.

Turlock와 Modesto 도시에서 재사용 폐수를 매년 5만9천 acre-ft 생산을 목표로 계획된 프로그램은 Delta-Mendota 수로를 통해서 수송된다. 재생수는 폐수처리시설의 파이프라인을 통해 Modesto와 Turlock로 이동된다

The US Bureau of Reclamation has set a public scoping meeting for 13 May 2014 as part of the environmental impact statement (EIS) process for the proposed North Valley Regional Recycled Water Program (NVRRWP) in California's San Joaquin Valley.

The NVRRWP is designed to address part of the ongoing California water crisis by making tertiary-treated recycled wastewater available to the drought-impacted west side of the valley south of the Sacramento-San Joaquin River Delta.

Under the proposed program, up to 59,000 acre-ft (72.8 million m³) per year of reused wastewater produced by the cities of Turlock and Modesto would be delivered via the Delta-Mendota Canal. Recycled water would be conveyed from Modesto and Turlock through pipelines from their wastewater treatment facilities, crossing the San Joaquin River, and ending at the Delta-Mendota Canal.

The recycled water would then be conveyed directly to Del Puerto Water District customers or to the San Luis Reservoir for storage during low water-demand periods. In addition it would provide water to Central Valley Project Improvement Act-designated refuges, south of the Delta, to meet their need for water supply.

While the first phase would mostly involve pipeline construction and diversion facilities, Phase 2 would include:

(1) storage facilities that would provide additional recycled water for irrigation while also providing migratory bird habitat
(2) development of stormwater and additional wastewater supplies to increase the total amount of recycled water availability.

Phase 1 alone is estimated to be capable of restoring US$ 29 million in annual agricultural production.
