The heating system in an office building required renovation. The options considered were replacing the 3 existing pumps with ones that were the same power and eventually replacing the thermostatic valves, as well as redesigning the system to have four sub-systems with optimized dimensions using equal friction loss per pump. The latter option allowed for smaller pumps to be used which cut down on the life-cycle cost.

A pump used in an open system for pumping water from circulation tank into two wire tanks was worn down and had decreased efficiency. Analysis was done to compare the cost benefit of installing two modifications to the existing system. With an increased demand required only during startup, the conclusion was installing a new smaller pump parallel to the old pump to provide the base load duty. The old pump would only be used during the start up period.

Overview: Replacements are being considered for a cooling water system that currently consists of four volute casing pumps. A cost analysis is done comparing the baseline versus variable pitch propeller pumps and mixed flow pumps with variable inlet guide vanes. Mixed flow pumps have the fastest payback in this application with a payback time of 0.4 years.

Overview: August 2024 – Stormwater – Upgrade of the system to accommodate storms and mitigate flooding. If the flooding wasn’t addressed then the problem would continue potentially affecting homes, utilities, and infrastructure. With existing utilities, a stepped-down wet well was utilized to prevent any problems with those utilities.
