Facilities Plans, Evaluations, Evaluation Studies
Facilities plans for the treatment and collection of
wastewater for various communities have been completed by
Hurst-Rosche. The facilities plans included studies to determine
the conditions of the existing system along with recommendations
for rehabilitation and reduction of wastewater flow by
eliminating excess storm water. The facilities plans analyze
alternatives to determine the most cost-effective solution based
on present value. Cost estimates for construction operation and
maintenance were included for each alternative.
Facilities plans were completed for the following
communities:
- Alorton-Centreville
- East St. Louis
- Atalissa, Iowa
- Hillsboro
- Donnellson
- Matherville
- Raymond
- Cahokia
- St. Elmo
- Sauget
- Commonfields of Cahokia
Water Projects
ADGPTV Water Commission
Treatment systems evaluation and capital improvement
feasibility study
Study all treatment processes including raw water supply
(impoundment) for treatment extensions, increased capacity,
upgrade potential and related costs. The distribution system was
also reviewed in terms of conveyance limits, pumping and
telemetry controls. A three million dollar capital program was
initiated as a result of this study as well as a treatment plant
increased capacity rating by EPA.
Commonfields of Cahokia
Reroute sanitary sewer
Cahokia, IL
Prepared plans and specifications for the rerouting of 500
lineal feet of existing sanitary sewers for the purpose of
eliminating an existing lift station.
Commonfields of Cahokia
Water system improvements
Public Water District
Cahokia, IL
Prepared plans and specifications for the replacement of the
existing monitoring/control equipment with a new SCADA system at
the Main office building, the Falling Springs Road duplex booster
station and 1.5 million gallon ground storage tank, the church
street elevated water storage tank and the Converse Street duplex
booster pump station. Also constructed a bypass oine with an
electric actuated valve, discharge lines and altitude valves.
Also blast and repainted the interior and exterior of the Church
Street elevated water storage tank.
Water and sewage system improvements
Greenville, IL
The City of Greenville replaced a 14-inch force main, a
gravity relief sewer, pump station, and installing water line in
13 areas. Hurst-Rosche Engineers, Inc. provided all standard
engineering services including project design, surveying,
specifications, bidding supervision and bid recommendations, and
engineering/construction supervision.
Rehabilitation of water treatment plant
Hillsboro, IL
Prepared plans, specifications and performed construction
observation for rehabilitation of water treatment plant.
Improvements included new sand filters, flocculator and
clearwell. Rehabilitation included settling basins, piping and
automation of controls. Capacity was increased from 2mgd to 3.5
mgd.
Water Treatment and Distribution System
Improvements and additions
Hillsboro, IL
Construction of 2 million gallon per day water treatment plant
with high service pumps; 7,500 lin. ft. of 14" water line;
2,000 lineal feet of 4" - 12" distribution piping with
related valves and hydrants. Engineering services included
surveys, preliminary and final plans, and construction
engineering.
Wellfield Evaluation
Commonfields of Cahokia, IL
Hurst-Rosche evaluated the feasibility to the construction of
a wellfield and treatment plant for the water district. A test
well was drilled and tested for quantity and quality.
