Summary

Monterey Water One's mission statement states that the organization is "dedicated to meeting the wastewater and water recycling needs of our member agencies while protecting the environment". Monterey Water One considers themselves to a customer service provider for utilization of wastewater. [1] Formerly known as the Monterey Regional Water Pollution Control Agency (MRWPCA), Monterey One Water was established in 1972.[2]. The name was changed between July of 2017 and the beginning of 2018. [3] MRWPCA was formed under a Joint Powers Authority agreement between the City of Monterey, the City of Pacific Grove and the Seaside County Sanitation District as a peninsula-wide effort to resolve area’s water issues and to provide the water treatment standards set in place by the Federal Clean Water Act.[4] Before the establishment of Monterey One Water, each individual community was responsible for the management of their own wastewater, which was often discharged discharge directly into the bay.[5]. Monterey One Water operates the Regional Treatment Plant, the Salinas River Diversion Facility, the Castroville Seawater Intrusion Project, sewage collection pipelines, and 25 wastewater pump stations [4]

Groundwater Supply

One of thekey functions of this organization is to ensure that potable water can be given to consumers without the overuse of groundwater resources. The history of this within the organization started when the in the mid-1970s when excessive groundwater pumping for agricultural purposes resulted in an overdraft of the underlying aquifer, exacerbating the effects of saltwater intrusion. The continued encroachment of saltwater (Salinas Valley Seawater Intrusion) into the Salinas Valley Groundwater Basin began to pose a serious threat to the regions multi-billion dollar agricultural industry, as well as limiting the drinking water supply for the City of Salinas. Community leaders began discussing possible solutions to address the growing concerns of saltwater intrusion, eventually deciding on the use of recycled wastewater to supplement crop irrigation, reducing the need to deplete groundwater reserves. After an extensive 11-year study the Monterey Wastewater Reclamation Study for Agriculture final report was released on April 3rd, 1987. [6] This document outline the feasibility of using reclaimed water for agricultural irrigation and address concerns about potential heath impacts associated with consuming crops grown with recycled water.[5]

Wastewater Treatment

In 1983, Monterey One Water was ready to implement its plan of an unified sanitation district. This process included the construction of a wastewater conveyance system that utilized neighboring treatment plant stations to distribute wastewater to one centralized facility.[7] These treatment plants were decommissioned in February, 1990, after the new 29.6 Million Gallon per Day (MGD) Regional Treatment Plant began operation.

Current Responsibilities

As of 2018, Monterey One Water is responsible for operating and maintaining 25 pump stations, 35 pressure-vacuum stations, and approximately 750 miles of pipeline and the Regional Treatment Plant treats and distributes 18.5 MGD for agricultural and domestic use. [7]

Projects and Facilities

Monterey One Water is a key stakeholder in the region's major water infrastructure projects such as:

Public Engagement
