New Design Road WTP Upgrade Honored by ACEC
(FAIRFAX, VA – February 26, 2013) – The American Council of Engineering Companies/MD has honored the design and construction of the recently completed New Design Road Water Treatment Plant Upgrade and Expansion. As part of the RK&K project team, Hazen and Sawyer was responsible for the architectural design for the plant upgrades as well as the process mechanical and structural design for the chemical feed systems, residuals handling facilities, and UV disinfection equipment.
In service since 1969, the New Design Road Water Treatment Plant (NDR WTP) provides drinking water to much of Frederick County, MD and also serves as a supplemental source for the City of Frederick. The facility was upgraded previously in 1990; however, continued growth in the City and County brought about the need to provide additional treatment capacity to meet the increasing demand.
The Frederick County Division of Utilities and Solid Waste Management (DUSWM) undertook a project to upgrade and increase the treatment capacity at the NDR WTP fivefold from a capacity of 5.4 mgd to a capacity of 25 mgd, produce water to meet existing and anticipated future drinking water regulations, and ensure the facilities could be easily, incrementally, and sustainably expandable to an ultimate capacity of 45 mgd.
Anticipating the County’s immediate need for added capacity, in the first phase of the project, an agreement was negotiated with the Maryland Department of the Environment to allow an increase in the plant’s filtration rate without constructing additional filters. In order to maximize the existing filters, innovative technologies including an ultraviolet light (UV) disinfection system were incorporated. This increased the treatment capacity within the existing structures by over 65% and satisfied the County’s immediate need for additional treatment capacity.
For the plant expansion in the second phase of the project, new structures were constructed adjacent to existing ones to maximize the use of County-owned property. Highly innovative building methods were employed, including the use of micropiles for the many deep foundation supports required, to keep the project on schedule and within budget.
The end result is an efficient, cost-effective, and most importantly, sustainable facility that will allow Frederick County and City to provide affordable, safe drinking water for the foreseeable future while minimizing the impact to the surrounding area.
Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
