Buckingham Park Water District—Water System Facilities Plan
In 2004 the Buckingham Park Water District experienced a severe water system supply problem.  The District had to truck water from a nearby community to meet the peak summer demands.  The District requested that WBA evaluate current and future demands and develop recommendations for increasing the water treatment plant capacity.  At the same time, a developer had notified the District that it was embarking on a project that could add as many as 100 single family residences to property within the geographical boundaries of the District but which had been excluded from the District’s service area.

WBA evaluated the existing facilities and proposed development and compared the projected flow requirements with the current plant performance.  WBA determined that the existing treatment units at the time should be able to meet the current demands if properly operated, but the additional capacity would be needed to meet the service area requirements when all the lots in the area were built out.  The proposed development would require significantly more capacity.  WBA’s Facility Plan provided an estimate of the construction cost for both the enlargement to meet the existing service area build-out needs and to meet the proposed development needs.

Buckingham Park Water District—Clearwell Expansion
In 2008 the Buckingham Park Water District retained WBA to provide plans and specifications for enlarging the water treatment plant’s clearwell.  The District had determined that the existing 30,000 gallon clearwell was too small to provide adequate detention time for disinfection during the peak summer usage period.  The District had had an inspection by the California Department of Health and had been informed that it needed more reservoir storage capacity in the system and it needed to have standby generator capacity at both the treatment plant and at the reservoir site with the booster pumps serving higher pressure zones.

WBA evaluated alternative locations for the new clearwell and, due to the limited area at the treatment plant site, determined the most cost effective solution for the District would be to put the larger tank in the location of the existing tank.  In order to provide the needed capacity during construction, WBA recommended using temporary storage tanks.  For structural reasons, the largest practical tank that could fit on the site was 218,000 gallons.  While this volume would bring the District into compliance with the health codes for the next few years, more reservoir capacity would be needed for full build-out of the District.

Dublin San Ramon Services District— Water Master Plan Updates
As District Engineer for the Dublin San Ramon Services District, WBA updated the existing water master plan to account for new development in portions of west Dublin not included in the original master plan. The update identified deficiencies in the existing water system and developed a program for expanding and upgrading the system to accommodate growth for 20-years into the future. Extensive computer modeling of the District's water system was carried out for this work.

In a later update, the water master plan was further modified to include annexation of new, undeveloped land in the east Dublin area, located east of the Camp Parks Army Reserve Base. The east Dublin annexation nearly doubled the total land area and population served by the water system. The major objective of this master plan update was to develop a sequential plan to provide water facilities (pipelines, reservoirs and pumping stations) in an area with no existing facilities to accommodate construction of new homes, businesses and associated infrastructure. The District's water system computer model was expanded to include the new service area and extensive modeling was carried out to allow the sequenced expansion program to be completed.
