Antelope Valley Water Storage Reservoir Design Project, Waterworks District 40, Los Angeles County, Alhambra, CA   
As Prime Consultant, LEE & RO is responsible for engineering, design, and construction support services for a $16 million water storage management project consisting of six 3-million gallon reservoirs.  The scope of work includes inspection, data analysis, preparation of plans and specifications, and cost estimating.  The project is divided into two phases - Phase I consists of four reservoirs and Phase II consists of two reservoirs.  The scope also includes the development of a Reservoir Operations Plan that will integrate the operation of 10 reservoirs, including four existing reservoirs, four new production/injection wells, chloramine disinfection, reservoir mixing/filling/drawdown/balancing operations, electrical, instrumentation and controls, pressure regulation, SCADA, and site security.
Arbor Ridge Domestic Water Reservoir and Booster Pumping Station, Walnut Valley Water District, Walnut, CA   
As Prime consultant, LEE & RO was responsible for the preliminary design report, final design, and construction management services for a new 1 million gallon capacity steel reservoir, a 3,500-gpm capacity booster pump station and various site improvements, including landscaping.  The final design of this $3 million project was completed in 2007 and the construction was completed in March 2009.
Parker Canyon Recycled Water Reservoir and Booster Pumping Station, Walnut Valley Water District, Walnut, CA   
As Prime Consultant, LEE & RO provided a preliminary design report, design, and construction support services for a new 1.3 million gallon capacity recycled water reservoir and three 750 gpm capacity vertical turbine booster pumps.  LEE & RO evaluated alternatives for at-grade and partially buried reservoirs for circular Type I & III prestressed concrete, rectangular concrete, and steel reservoirs.  Study concluded a partially buried cast-in-place two celled concrete reservoir with a demonstration garden feature atop the reservoir.  The demonstration garden includes a shade structure, drought resistant plants and low capacity sprinkler heads, so the facility can be used to educate citizens, students, and water users on the value of water conservation and recycling.  The final design of the $4 million project is underway and the construction is scheduled to start October 2009.

Extraction Well Network, Sanitation District of Los Angeles County, Whittier, CA   
As Prime Consultant, LEE & RO was responsible for design and construction phase services for a $4 million groundwater water extraction and transport system for the Palmdale Water Reclamation Plant Effluent Management Site.  The project extracts groundwater contaminated with nitrate and pumps it back to the Palmdale Wastewater Treatment Plant for treatment.  The project included extraction wells, booster pumps and groundwater conveyance piping network.  Construction was completed in 2008.
Distribution system Treated Water Cross Connection Prevention Program, Metropolitan Water District of Southern CA   
As Prime Consultant, LEE & RO is responsible for preliminary design and final design of relocation and/or modifications to approximately 100 air and vacuum relief valves installed on the large diameter MWD water transmission & distribution pipelines throughout the Los Angeles County area.  This project objective is to eliminate the possibility of cross-contamination in MWD’s main water distribution network.  The total construction cost is estimated at $9 million.  The construction is scheduled to be complete in June 2010.
San Joaquin Reservoir (SJR) Pumping Station and Flow Control Facility, Irvine Ranch Water District (IRWD)     
As Prime Consultant, LEE & RO was responsible for planning, design and construction support services for the $3 million, SJR Flow Control and Pumping Facilities project.  This project consisted of an 8,250 gpm pumping station (with three 75 hp, 4,125-gpm, VFD-driven pumps), flow control facility, hypochlorite disinfection facility, and sub-surface water collection and pumping facility at the base of the dam.  IRWD purchased the SJR from MWD and converted it to a reclaimed water storage reservoir, integrating it into their Zone B recycled water system.  Construction was completed and it has been in operation since 2007.
