From .75mg steel tank rehabilitations to new 40mg pre-stressed concrete reservoirs, IEC has demonstrated consistent and extensive experience in storage tank design. Example projects include: • 40mg
Twin Oaks Reservoir, Vallecitos
Water District Pipeline projects can involve a multitude of complicated issues that, if not carefully addressed, can have costly implications during construction. IEC is thoroughly familiar with the critical issues that need to be addressed for a successful project. These include utility research, materials selection, easement and right-of-way issues, and community and environmental acceptance. Central to this approach is our time-tested and methodical utility-research procedure. Proper depiction of existing utilities on pipeline design drawings will either make or break a project. We first identify all potential utility agencies having jurisdiction in the project area. Following this identification, we coordinate with each agency in writing to ensure proper documentation at each stage of the process. Check prints are sent out at each submittal milestone for conflict check, and each stage is documented on standard forms. This ensures a well-coordinated utility research, documentation, and plotting procedure in order to avoid costly changes during construction. Recent projects include: Water/Recycled Water Wastewater IEC has designed water and wastewater pump stations throughout California, ranging from small rehabilitation projects to 10,000gpm new stations. We are experienced in all aspects of pump station design, including pump selection, mechanical piping and valves, building/site layout and design, and electrical/telemetry design. Recent IEC design projects include: • Graham
Pump Station, City of Mountain View
Flow Control Facilities (FCFs) are an essential link from major aqueduct systems to local distribution systems. IEC is experienced in the planning, design, and construction management of these types of facilities. Issues to be encountered include proximity to the aqueduct system and the connection point to the local system, hydraulics including proper selection of the control valve to minimize cavitation, facility layout and ease of access, and operation and maintenance considerations. IEC also has experience with groundwater well facilities. The development of local water supplies has become an increasingly important component of the many agencies' overall water supply strategy. Recently, the potential for groundwater resources to supply some of the region’s needs and offset imported water deliveries has gained increased importance. Successful projects in Southern California have demonstrated the feasibility of groundwater use for municipal supply. IEC is experienced with groundwater development programs such as conjunctive use and conventional groundwater extraction and treatment. These projects are complex and multi-disciplinary with considerations such as environmental impacts due to groundwater pumping or recharge operations, treatment requirements, groundwater flow and delivery pressures, seasonal use, and community impacts.
