Mission Springs cracks down on industrial pretreatment compliance, cuts water to non-compliant facility

Mission Springs cracks down on industrial pretreatment compliance, cuts water to non-compliant facilityThe California utility has placed four industrial dischargers on a 180-day compliance clock under new tolling agreements, signaling a firm regulatory stance that includes severing water service for operators failing to meet wastewater standards.

Four facilities—Jeter, Morongo Equity Partner 1, Culture Cannabis, and Morongo Equity Partner 3—entered tolling agreements on June 15 to achieve wastewater compliance within 180 days.

The district shut off water service to one facility that failed to meet pretreatment standards and refused to enter into a tolling agreement.

Approximately seven industrial facilities, including a returning MedMen site, are currently undergoing continuous pretreatment testing by the district.

Facilities under tolling agreements met their first milestone on August 17 by submitting action and work plans, which the district will review by September 15.

Mission Springs Water District (MSWD) is actively escalating enforcement of its industrial pretreatment program, utilizing tolling agreements and service shutoffs to bring non-compliant facilities into line with municipal wastewater regulations. During a September 2, 2026, board workshop, MSWD Engineering Manager Eric Weck detailed the district's recent regulatory actions targeting industrial dischargers, primarily within the local cannabis sector. On June 15, the district executed tolling agreements with four facilities: Jeter, Morongo Equity Partner 1, Culture Cannabis, and Morongo Equity Partner 3. The agreements place the operators on a strict 180-day timeline to achieve wastewater compliance. Under the terms of the tolling agreements, the facilities must meet specific project tasks and deadlines to demonstrate progress, including the submission of sample action plans and implementation work plans. All four facilities successfully met their first major milestone on August 17, and MSWD staff are currently reviewing the submittals to provide feedback by September 15. The operators will then be required to report back on any necessary modifications to fully achieve compliance. The district has demonstrated a willingness to utilize its ultimate enforcement tool—terminating utility service—for industrial users that refuse to comply. According to district staff, six facilities were initially identified as failing to meet pretreatment agreements. While some resolved their issues or entered into the new tolling agreements, one facility failed to comply and refused the tolling agreement. In response, MSWD officially shut off water service to that property, adhering strictly to the enforcement actions outlined in its municipal ordinance. MSWD is currently testing and monitoring approximately seven industrial facilities for pretreatment compliance, a roster that includes a MedMen facility that is coming back online. The district noted it is working closely with the local city to identify new operators moving into industrial buildings to ensure initial inspections are conducted and pretreatment standards are enforced from the outset of operations.
