<br />Well No. 32 Rehabilitation. Citv of Santa Ana. Cf Structural Years with Tetra Tech:
<br />Design Engineer. The project involved the preparation of a PDR and 14
<br />plans/specifications for the rehabilitation of the well facility. The
<br />underground well would be scraped, cleaned and modified to be within an above ground CMU block
<br />control building (housing mechanical and electrical rooms). The design also included civil, structural,
<br />and electrical improvements to the park adjacent to the well site; a separate on -site generation sodium
<br />hypochlorite building; 3,500 feet of 12-inch discharge pipe to John Garthe Reservoir; pressure control
<br />vault and chemical injection vault for both Well 32 and the City's existing Well 24; and modification at
<br />the reservoir to connect to the on -site piping.

<br />CA. Structural Engineer responsible for the design of four injection wells to be located within Centennial
<br />Park in the City of Santa Ana for Orange County Water District. In addition to the engineering services
<br />for the four injection wells, the project includes the design of the supply pipeline, backflush pipeline,
<br />bridge crossing, two shared facility sites, a monitoring well site, site improvements, and paving of park
<br />access roads and parking lots.
<br />essure Reducing station Kelocatlon, Ivlounon Nlguell vvater ulstrwt, Laguna Niguel, CA.
<br />Structural Engineer for the Pressure Reducing Station Upgrades for the District. This work included the
<br />relocation of three pressure reducing stations. The station was located within the street right-of-way and
<br />relocated in an existing parkway.
<br />Mathis Oso-Bypass, Moulton Niguel Water District, Laguna Niguel, C. Structural Engineer for the
<br />Flow Control/Pressure Reducing Station for the District. The existing pressure reducing station was
<br />modified to include flow control capabilities. The piping arrangement within the existing vault was
<br />modified, the size of valves was changed and the new flow control/pressure reducing station was
<br />re -located within the street right of way in a left turn pocket.
<br />Lvng oeat:n valve mepiaceMent, Long Beach Water uuparirnerit, Long oeach, Gr Structural
<br />Engineer for improvements to an existing Flow Control/Pressure Reducing Station for the Department.
<br />The improvements included the removal of existing piping and control valves with the replacement of
<br />new butterfly valves and plunger valves. The pressure reduction in this station was approximately
<br />180 psi and required that the plunger valve be designed and sized properly to handle such large drop at
<br />this station.
