water system engineering

Perhaps our most valuable resource, yet it is seldom given much thought by those who rely on efficient systems to bring fresh, clean water into their world. Many people simply gather a glass, turn on the faucet and drink. At Bell Engineering, we understand the planning, cost and logistics required to provide abundant clean water. We can help determine adequate raw water sources, treatment methods, storage, modeling and water quality solutions for your community.

We are recognized as having pioneered new technology in filtering processes as well as diminishing chemical residuals in finished water to meet and exceed state requirements. Our team of water engineers is regarded as some of the best in the industry and we pride ourselves on being up to date with all modern solutions. Bell Engineering offers a full range of engineering services for water systems.

Bell's water system services include design, permitting, construction management, inspection and operational assistance for pump stations, storage reservoirs, transmission and distribution mains, pressure reducing stations, water treatment facilities and chemical feed systems.

water treatment facilities
Water treatment was one of the first specialties of Bell Engineering. Our founder, Howard K. Bell, was the chief engineer for Lexington's water company before opening the doors of the first consulting engineering firm in the state of Kentucky in 1914. From the beginning, Bell plants were known for their durability and for the all-important fact that they worked. Since those early days, treating water to the level required by government regulations and an ever more discerning public has become increasingly more complex and expensive. Add to that the demands imposed by rapidly changing and variable raw water quality and quantity, and the task of providing clean, acceptable water is daunting.

Focusing on the region we serve, Bell provides a team of highly respected, dedicated individuals who have experience in every aspect of water treatment and every phase of a water treatment plant project. Drawing on engineers with prior experience as utility managers, state regulators or licensed water treatment plant operators, our team is able to address any treatment issues that may arise. Each project benefits from all of these resources working together from the same local office.

Our experience encompasses an impressive range of advanced approaches to every aspect of water treatment, making sure that the processes designed fit the unique characteristics of the situation. Several of the water treatment plants designed by Bell staff were the first of their type in the state, and year after year, our plants garner awards from a number of professional organizations. Our approach takes into account all of the applicable parameters - from the level of treatment needed to the managerial, technical and financial capabilities of the client, we will design a project that meets your needs.

water storage facilities
Water storage facilities, both clearwells at water treatment plants and underground, ground or elevated storage tanks in the distribution system, are a lot more than just big water bottles. At Bell, we understand that water storage facilities are an integral part of the overall water system. Every aspect of their design and construction is important to the system, including location, size, configuration, water quality maintenance considerations and aesthetics.

The Bell team considers all relevant aspects of a water storage project in the evaluation and design phase. For clearwells, we ensure disinfection requirements can be met under all conditions required by the utility's water quality and treatment techniques. For distribution system storage, meeting the requirements imposed by peak demands and fire flows is only one part of the puzzle. We also look at relevant parts of the entire distribution system, ensuring that the tank location and configuration will function in a way that minimizes any effect on water quality parameters. On numerous occasions, Bell has modified existing storage tanks to help the system achieve or maintain compliance with water quality regulations.

water distribution
Water distribution systems are designed to provide dependable, high quality water to customers within a distribution service area. In order to accomplish this, distribution systems must be designed to preserve the quality of the water delivered by the water treatment facility. Design considerations include main size, water storage tank capacity and design and adequate provisions for flushing and elimination of dead end water lines. Beyond water quality, the distribution system designer must also ensure adequate system pressure during all conditions of flow.

Bell Engineering provides design services for both large and small distribution systems including new projects and renovations or upgrades to existing systems. Rehabilitation is becoming more commonplace as existing distribution systems succumb to deterioration due to age along with customer bases that have grown beyond the scope the system was originally designed to meet. Inadequate pipe size and improper materials are also common reasons that systems require rehabilitation or upgrades. Our team can provide an honest assessment of your system and help you develop a project that best accommodates your needs.

hydraulic modeling
The best model of any water distribution system is always the distribution system itself. However, the second best model is a computer simulation of the system, which offers uses that would be impractical or even impossible to perform with the actual model. Computer models can be especially valuable in evaluating "what if" scenarios. "What if" we expanded the distribution system, "what if" the pump station capacity is increased or "what if" a waterline is designed with a 4-inch diameter rather than a 6-inch diameter? All of these questions can be answered with the development of a computer model for simulation purposes. Bell can provide KYPIPE, WaterCAD (Bentley) and Innovyze InfoWorks CS models and provide training to operators in their uses.

A well-calibrated distribution system hydraulic model is an extremely valuable tool for both the design engineer and the distribution system operator. For the design engineer, the model may be used in the design of new or replacement components within the system. For the distribution system operator, the model may be used as a tool for a number of different scenarios including locating leaks, closed or open valves, non-functioning air release valves and water quality simulations.
