Drinking Water
Mission
SGM's Drinking Water Team strives to develop safe, reliable, sustainable drinking water systems for the communities in which we work.
Approach and Values
We pursue this mission by delivering responsive, high-quality, best-fit solutions to the challenges of western Colorado water providers. We first always listen to our clients’ needs and make the effort to understand the big picture and root problems. We involve senior staff early in a project, and we thoroughly evaluate the best options and consider future needs to ensure that our clients get the “right solution” the first time around! We then engineer high-performance, right-priced, operator-friendly facilities.

Water Rate Studies
-
- We regularly assist the clients for whom we serve as the Engineer of Record in developing or updating water rate/fee schedules

- We encourage utilities to implement full-cost pricing for long-term financial sustainability and reduced reliance on outside funding for mission-critical improvements
- Recent rate studies include:
-

- high utility performance and great client service
- "living" other utility-specific goals/values
- We partner with John Ruetten, a water/wastewater utility branding expert, of Resource Trends and founder of the Utility Branding Network to bring customized utility branding planning, training and support services to our small system clientele
- Rifle Utility Branding Consulting

Review of New Development Water Systems
-
- For clients of whom SGM serves as the Engineer of Record, we routinely evaluate developer-proposed water system extensions
- We are strong, successful advocates for our clients in this process
