Ever changing regulations for environmental and health issues make water and wastewater management the most challenging components of our nation's infrastructure. These issues are further compounded by growing populations and expanding development. The combination of these issues has put significant demands on aging infrastructure and operational procedures that have driven the need for major infrastructure modernizations, rehabilitations, replacements and expansions. At SVS our experience in addressing the technical challenges related to these projects and our appreciation and tact in considering the political pressures has placed us as one of the top value consultants for water and wastewater related projects.
We have conducted studies on every aspect of water resources projects from raw water reservoirs to raw water conveyance systems to water treatment and filtration facilities to disinfection strategies to pumping stations to finished water reservoirs to finished water distribution systems , bio-solids handling and more.
Our wastewater experience also includes new plants, plant expansions, process upgrades including digester upgrades and sludge handling, combined sewer overflows, pump stations, pipelines, tunnels, collection systems, interceptors, operations and maintenance facilities and more.
Ozone Treatment Conversion & Electrical Improvements
SVS conducted two studies on plant improvements of a major regional water treatment plant. The first improvement project involved upgrading to ozonation facilities from chlorine treatment as the primary disenfectant and conversion of the existing plant multimedia filters to biologically active filtration units. The second improvement project upgraded the internal electrical system, providing modern backup and failure failsafes.
100 MGD WWTP Plant Capacity Improvements & Biological Nutrient Removal Process Upgrades
This Project aims to improve the advanced wastewater treatment facility by removing more ammonia as well as nitrates. The discharge permits for the facility are becoming increasingly stringent. The 2008 Facility Upgrade Plan recommended that the facility be converted from the HiPOS to a traditional activated sludge process, with provisions for biological nutrient removal. SVS conducted a 5-day study on the project, providing alternatives for over $30 million in savings. Additionally, the Value Team proposed alternatives that significantly reconfigured the Primary Effluent Pump Station, improving the overall functionality and capacity of the facility.
Water Treatment Plant Expansion Project
New water quality regulations and increased water demands have necessitated an upgrade and expansion of the this 4mgd direct filtration plant. The primary water quality objectives are to meet the state regulations for disinfection and disinfection byproducts (D/DBP) and improvements to taste and odor. The water capacity needs to be expanded to serve a rapidly expanding industry that wants treated to facilitate their processes.
The existing facilities could not practically be modified to deliver the required flow rates so the “expansion” project is effectively a new plant. The new plant will use pre-ozonation followed by direct filtration followed by free chlorine disinfection. The filter bed will consist of six cells using a deep-bed with 12-inches of sand and 48-inches of anthracite. The new plant will be built adjacent to the existing plant to make use of the existing building for administrative and maintenance functions.
The Value Team provided accepted recommendations resulting in savings of over 10% in immediate savings on this plant expansion project, but more importantly, Operations & Maintenance were improved and a configuration that would simplify additional expansions, if necessary, was also provided.
Modernization of 70-Year Old Water Treatment Plant
SVS provided value services on this upgrade and modernization the existing water treatment plant in the Midwest, originally constructed in the 1930's. The existing plant uses well water, which it aerates, settles out solids, and filters. The value team reviewed the plan which includes the addition of one new well, modifying the existing wells to increase the pumping head capacity to deliver water to a new aerator, adding a new induced draft aerator to replace the existing diffused aeration system, adding new rapid mix chambers to improve the mixing of the lime, polymer, and chemicals prior to the flocculation chambers, adding flocculation basins with mechanical mixers, modifications to the existing sedimentation basins, replacement of the filter media and underdrain system, addition of an air scour system, and improvements to the sludge handling facilities.
