Huntingon Beach – Well 13

WHB Engineers completed the design of the new Well No. 13 Chlorine Storage Building for the City of Huntington Beach. Access on this site was constrained with two large potable water reservoirs; one 17MG capacity and a smaller 9MG reservoir. 

In addition, three groundwater production wells were located onsite.  The existing chlorine storage building was designed to store four 150-pound chlorine containers.

WHB Engineers designed the new chlorine storage building, including all associated electrical, instrumentation and control system components. 

The new building facility was upgraded to store two 1-ton chlorine storage cylinders, incorporating TGO system components to meet Uniform Fire Code requirements for full containment.  The new one-ton chlorine storage cylinders required the design of a monorail-mounted crane for support. 

WHB Engineers team designed seismic upgrades and seismic monitoring using SCADA that would automatically shut down the chlorine system in the event of a 4.0 or greater seismic event.

The design upgrades increased facility safety and reduced the risk of chlorine exposure to workers and residents by implementing zero release and passive mitigation technologies, rendering scrubbers unnecessary.  The new system prevents the generation of hazardous waste and reduces the cost of ongoing O&M.
