How Investing in Modeling Helped Harriman Utility Board Pinpoint Pipeline Flow Capacity Restrictions



CHALLENGE:

Harriman Utility Board (HUB), a utility company servicing residents of Harriman, Tennessee, hired Magnolia River to model their system to assist in gas pipeline replacement. After building and solving the system model, Magnolia noticed a residential area was experiencing near zero pounds per square in gauge (PSIG) pressure just a few blocks away from a 30 PSIG area.

ACTIONS TAKEN:

Magnolia River assumed the zero PSIG was due to a missed connection in the model or a mislabeled pipe size. As Magnolia was reviewing the model with HUB, HUB verified the model was true and the residential area did experience near zero PSIG on their coldest day. Magnolia suggested HUB install a new 2” PE main to resolve the low pressure problem. The model indicated the pressure in the concerned residential area would increase by 15 PSIG.

RESULTS

HUB installed a new 2” main just in time to test the 2 °F weather of winter. The minimum pressure in the residential neighborhood held at 15 PSIG. Harriman is proof that prioritizing modeling is well worth the results.
