Booster Pump System

The Problem
The building had originally had a 3-pump booster system in place for providing water services to the tenants. Complications began to arise where the system would neglect to restart after shutting off, early signs that the booster system would fail. Also, there was no redundancy in place to continue providing water in the event of a pump failure.
The Solution
In response to these issues, our team designed a brand-new system of 2 skids with 4 pumps each. This was designed so that if one pump were to fail, there were three pumps in place to continue functioning. If an entire skid were to fail, the remaining skid still had the capability to continue providing water to the entire building.
The Outcome
We sent the design to Grundfos, the manufacturer of the pumps being used for the facility, and they were extremely impressed. They commended us on the fact that they had never seen such effective redundancy systems in place before.

Sanitary Risers

The Problem
The sanitary lines, which run waste (laundry, kitchen sinks, bath tubs, and toilets) from higher to lower floors, were installed incorrectly – without clean outs (service points) and nearly level; without any slope to facilitate downward movement of the waste. This caused a build up of material in the pipes and back ups on the floors above. The Board of the building was faced with a decision to either tear out and reinstall the pipes at the right angle (a very high cost considering the amount of drywall and finishes to be replaced, or create a system of regular maintenance to prevent any issues in the future.

The Outcome
This solution allowed the client more flexibility, as the tenants would not face any inconvenience of extensive work being done on the sanitary lines that were connected to their units. It was also a much more cost-effective solution for the client.
