Custom Panel Installation: Mesa Consolidated Water District


What they had . . .

Mesa Consolidated Water District (MCWD), located in Costa Mesa, California, has three stations which utilized a combination of dated Murphy S100, S400, and S500 controllers.

MCWD recently made the decision to update their SCADA network, while concurrently updating their controllers to the latest system, the Series 600 Controller (S600).

The facility features two reservoir/booster pumping stations and one well/booster pumping station. The reservoir stations have generator engines, in the event of a power loss. One of the reservoir stations used two control panels to control the area drainage pumps and sump pumps for the reservoir.


What they needed . . .

MCWD made the commitment to upgrade their controllers to the S600 platform to facilitate accessibility to their new and improved SCADA network. The amount of data being transferred had increased and MCWD needed a better real-time view of their stations through SCADA.

The new S600 controllers have an easy to use HMI touch screen, giving operators a better visual representation of what is going on with their engines.

One of the most important requirements was to maintain emissions compliance with the local Air Quality Management District. Part of the upgrade package was to retrofit all of the engines with new air fuel ratio controllers, which are built into the S600 controllers.

MCWD also wanted to upgrade their electronic ignition system for each engine. It was essential that the entire solution worked together.


What they received . . .

Inside reservoir #1 we installed a new S600 Central Controller that controls and automates three new S600 engine controllers. This reservoir also houses two generator engines which received new S600 controllers.

Pertinent data from all of the engine controllers, including the generators, is routed through the central controller and provides a one spot connection for their SCADA. The central controller automates the operation of two electric driven pumps and up to four engine driven pumps.

Staging is automated, based upon pressure and flow set points. Reservoir #2 operates in a similar fashion as Reservoir #1. 

Well #5 is a stand alone controller without a central controller. The engine can start and stop automatically and perform automatic throttling.

Each engine was fitted with a new Compliance Controls air fuel ratio controller (AFR) and a Murphy Power Ignition (MPI) ignition control system. Data from the AFR controller is displayed on the touch screen HMI.

The MPI and AFR controllers can be used as diagnostic tools to determine failed spark plugs and other faults occurring with the engines.

These components work together seamlessly to provide a complete solution for MCWD.
