Reserve at Riverside Water Booster Station, Harford County, MD
MRA provided the hydraulic analysis, planning, design engineering, surveying, landscape architecture and construction services for the two prefabricated skid mounted potable water booster stations that serve provide both domestic and fire supply to the Reserve at Riverside Community. Each station is complete with two 300 GPM, 15HP, VFD operated domestic pumps; one 1,500 GPM, 75 HP fire pump; two 65-gallon hydropneumatic tanks; controls, telemetry system, and bypass pumping capabilities. Each booster station is housed in a building consistent with the community’s architecture and share space with the water meter room and the operations personnel.
Town of Hampstead 12-Inch Water Main, Town of Hampstead, MD
MRA provided planning, engineering, and construction phase services, as well as surveying for 3,510 LF of 12-inch water main extension that parallels Md. Route 30 in the Town of Hampstead to support annexation areas to the Town. Elements of design included a preliminary alignment study, property search, survey, preparation of easement plats, sediment control, and Town and County approval coordination. Installation included open cut, jack & bore, and directional bore techniques.
NSWC, Carterrock Underwate Explosive Shock Test Pond, Montgomery County, MD
MRA evaluated and submitted for approval an investigative study of the water chemistry and filtration system of the 26-foot-deep, 3-MG pentagon-shaped test pond. Engineering services included evaluations and recommendations of the recirculation/filtration system, skimmer system, chemical system, monitoring/automation system and the rehabilitation of the 12-inch diameter cast iron intake line.
Abingdon Road Water Tank and Booster Station, Harford County, MD
MRA provided planning and design of the 2.0-million-gallon elevated water storage tank with two 2,330 gpm Zone 2 booster pumps mounted in the base of the fluted column.
Bulle Rock Water Towers, Havre de Grace, MD
MRA provided planning and design of a 500,000-gallon waterspheriod water tank to supplement existing Zone 2 storage to serve the Bulle Rock Community in the City of Havre de Grace.
The design of a 600,000-gallon elevated water storage tank has been completed by MRA to create a new Zone 3 (high zone) to serve a proposed 100-acre medical campus and 100-acre mixed-use development recently annexed into the City.
The system expansion is based on the Havre de Grace Water System Master Plan prepared by MRA.
Village of Cecil Woods Water Standpipe, Cecil County, MD
MRA provided engineering services to evaluate and develop an upgrade program for the existing water treatment plant, groundwater sources, and sewage pumping station serving 134 active adult residences. Additional services were provided to determine necessary improvements to support the addition of 100 residences to the community.
A program of recommended operational improvements to the existing water treatment plant was prepared to support continued operation of the plants including recycling of filter backwash water. A 62,000-gallon standpipe was constructed to equalize peak and instantaneous demands. The process controls were modified to integrate the storage tank with the Trident package plant, chemical addition for disinfection and pH adjustment, hydropneumatic tank, and two wells.
A low pressure sewer system (LPSS) was designed as an alternative to a system comprised of a conventional gravity sewer system and four sewage pumping stations to serve the additional 100 residences that were located in an area of extensive wetlands.
In support of the expansion of the community, an outline of improvements to the existing sewage pumping station was developed to enhance performance and ensure safe pumping capacity.
