South City Utility Assessment Summary

 

The South City Campus is located at 1575 South State Street. The campus currently serves approximately 1,665 students, and has plans to add an additional 1,667 full time students. The campus contains roughly 28 acres, six of which appear to be landscaped.

Water System

The South City campus appears to have a dedicated fire line service. For culinary needs the campus contains two 4" lines and one 3" line. In our analysis, we assumed a flow of 5ft/s, and a need to serve 3,415 people. We used the Division of Drinking Water standards, and estimated a peak day demand of 15gpd. We found, based on our assumptions, that the current system is capable of supplying the water required by the South City Campus for both the existing and the proposed additional students. This conclusion is also based on the assumption that the dedicated fire lines are adequate for existing and potential growth.

Sewer System

It appears that the campus is serviced by a minimum of two 8" lines. We assumed that both lines were 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 and proposed demands.

Irrigation System

The drawings provided do not show any irrigation lines. For analysis purposes, 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.
