本文描述了加利福尼亚州的水质项目如何影响水处理和分配设施的废物排放。除非另有说明，本文中的信息基于圣地亚哥地区加利福尼亚州区域水质控制委员会（CRWQCB，SDR）管辖范围内的实践和程序。对于液体排放（来自现场卫生设施或过滤反冲洗水）和固体排放到土地进行处理、储存或处置的情况类似，但在前一种情况下，区域水质审查委员会可能只指定排放的质量标准，而在后一种情况下，委员会也可能指定遵守这些标准的方式。 表格给出了危险废物成分的标准（单位:mg/L和mg/kg）；第二个表格总结了土地排放的废物管理策略。一个案例研究强调了这些法规如何影响水处理厂及其扩建。简要讨论了与配水系统冲洗（可能需要NPDES许可证才能排放到地表水）和非法泄漏和排放相关的法规。

This paper describes how water quality programs in California may impact discharges of wastes from water treatment and distribution facilities. The information in this paper, unless otherwise indicated, is based on the practices and procedures within the jurisdiction of the California Regional Water Quality Control Board, San Diego Region (CRWQCB, SDR). In the case of liquid discharges (from on-site sanitation or filter backwash water) and solids discharge to land for treatment, storage, or disposal are similar, except that in the former case the regional water quality review board may specify only quality standards for the discharge, while in the latter case the board may also specify the means of complying with those standards. A table gives criteria for constituents of hazardous wastes (in mg/L and mg/kg); a second table summarizes waste management strategies for land discharges. A case study highlights how the regulations affect a water treatment plant and its expansion. Regulations relevant to distribution system flushing (which may require an NPDES permit for discharge to a surface water) and illicit spills and discharges are briefly discussed.
