SPRING DEVELOPMENT

Ken Bousfield, P.E.

Utah Division of Drinking Water

WHEN IS A SYSTEM PUBLIC?

Prior to Construction:– Plan Review Issues– Source Water Protection

After Construction– Construction Inspection

After Use Meets the “Public” Definition– Water Quality Monitoring

BASIS FOR RULES:

–Plan review a “Primacy” requirement

–Engineering principles–Experienced based rules

PRELIMINARY CONCERNS:

– Water Rights– Source Protection– Under the Direct Influence– Chemical Quality– Source Capacity

PLAN REVIEW PROCESS:

– Anticipated Design– “As Built” Plans– Bacteriologic Quality – Operational Permits
