Miller Utility Assessment Summary

The Miller Campus is located at 9750 South and 300 West. The campus currently serves approximately 250 students. There are plans to add an additional 40,000 square feet of space, which translates into capacity to serve an additional 267 students. The campus contains roughly 20 acres, five of which appear to be landscaped.

Water System

There are two water lines that serve the Miller Campus. The first is an 8" line which comes off of 300 West, and the second is also an 8" line that services the campus from 9800 South. For the Miller Campus, we assumed a flow of 5ft/s, and assumed a need to serve 517 people. The 517 people count includes existing students and the proposed new students that would be attending the campus after the additions. We used the Division of Drinking Water standards and estimated a peak day demand of 15gpd. We also analyzed fireflow volumes and used 1,500 gpm as a required minimum. We found, based on our assumptions, that the current system is capable of supplying the water required by the Miller Campus now and after the additional students are added.

Sewer System

It appears that the Miller Campus is served by a single 8" sewer connection, which leaves the campus on the north end and connects to an existing line at 9400 South. In order to analyze the sewer system we assumed the line was constructed with a minimum slope, and running 80% full. We also assumed that 100% of the culinary water used for human consumption returned to the sanitary sewer system. Based on our assumptions, we found the existing sewer is capable of meeting current demand and the proposed additions.

Irrigation System

The drawings provided show an irrigation main line, but the line does not appear to connect to any campus lines. Therefore, we assumed that all water used to service the landscaped area is culinary. The demand for the landscaping water was accounted for in our water system analysis, and we determined that the existing system is adequate for the current amount of landscaped area. Again, this analysis was done using the Department of Drinking Water standards and regulations. Analyzing irrigation pipe sizes and adequacy of those lines to effectively meet campus requirements is beyond the scope of this investigation.

Other Notes/Action Items

The evaluations made were based on the assumption that the interior piping systems for the water, sewer and irrigation lines are working properly. Various assumptions were made for each utility analyzed, and further design would require a significant amount of additional analysis. The information used came from: Division of Drinking Water, AJC Architects and the SLCC website.
