KEM developed a model and completed a study of the entire Village of Bellville water distribution system, resulting in a list of recommended improvement projects. The system wide model revealed that the northeast portion of the Village has very low pressures in addition to low fire flows throughout the Village due to a number of 4 and 6-inch water lines. KEM recommended four improvement projects to increase pressures in the northeast portion of the Village and to significantly increase the fire flow capacity throughout the Village. KEM has completed the design and construction management for the first phase of the improvements which included the installation of 7,400 feet of 12-inch water main that serves as the new “backbone” of the entire water distribution system.
KEM developed a model and completed a study of the entire Village of Butler water distribution system, resulting in a list of recommended improvement projects. The system wide model revealed that the northwest area of the Village has low pressures in addition to low fire flows throughout the Village due to a number of 2, 4, and 6-inch water lines. KEM recommended 6 improvement projects to increase pressures in two separate pressure zones and to significantly increase the fire flow capacity of the village-wide system.
The City of Mansfield identified three areas throughout the city in need of water distribution system upgrades. KEM modeled each of the areas to properly size the proposed improvements and then performed field survey, base mapping, easement acquisition and design services to develop plans for the construction of said improvements. The project consisted of over 13,000 feet of 8 inch water main, 36 hydrants and 236 service connections.
KEM developed a system wide model and completed a study of the entire Village of Plymouth water distribution system, resulting in a list of recommended water system replacement and extension projects. The system-wide model revealed that the Village had various zones of low pressures and low fire flows due to a number of existing 4-inch water lines in the system. KEM also conducted a water and sewer rate study as required in the applications for Ohio EPA loan and OPWC grant monies to pay for said improvements. KEM then prepared construction plans for the replacement of these undersized waterlines and for looping of the system to increase flows. The first phase of the water system improvements were completed in 2003, which included the installation of 12,000 feet of new 8-inch water main. The second phase of the improvements were completed in 2015 and included over 11,000 feet of water main replacement.
KEM completed design for the existing Riggs Street elevated water storage tank repaint project. The existing structure is a 250,000-gallon pedestal spheroid water tank originally constructed in 1964. The tank has had several overcoats and spot repairs over the years, but had not been stripped down to bare metal and repainted.
KEM performed the design for a new elevated water storage tank for the Village of Plymouth. Located next to the local school facility, this new tank was designed to provide a ready volume of water for both daily usage and fire protection for both the school and the Village. The 100,000-gallon tank was bid as a pedestal spheroid water tank with a bolted steel composite tank alternative. Upon evaluation of the bid alternatives the Village selected the bolted steel composite tank based on its reduced maintenance over its life span. The water tank design included as altitude valve and a new telemetry system to control booster pump operation and tank levels.
KEM completed a Village wide study of the existing potable water distribution system to determine a plan of action for the replacement of their aging water mains and hydrants. Also included with this study was an analysis of the pressures measured throughout the distribution system along with recommendations of how to improve the system through looping and other options. KEM then completed the survey, design, bidding & construction management for the first 4 phases of improvements. These improvements included 14,00 LF of water mains, 36 hydrants and 209 service laterals.
KEM completed a study of the entire Village of Lucas potable water distribution system from which a list of recommendations was developed to improve operating pressures, flow capacities, and fire flows throughout the Village. It was also imperative to come up with a plan to service the new high school, on the northeast edge of the Village. KEM also designed two pump houses and a chlorine system for Lucas water treatment.
The City of Elyria contracted with KEM to prepare construction plans and a cost estimate to replace 5,885 feet of water main within the St. Jude Area on the City's east side. Work items included 38 gate valves, 11 fire hydrants and the reconnection of 110 service branches to abutting property owners.
The City of Ontario contracted with KEM to prepare construction plans, bid documents and construction management services to replace 1,200 feet of water main along Ferguson Road. Work included; 250'- 8" water main, 1,200'-12" water main, 5 gate valves, 6 fire hydrants, and a bore and jack of Lexington-Springmill Road.
Lorain County was petitioned to provide sanitary sewers to open development within Columbia Township. The county hired KEM to provide a preliminary study to determine the best way to serve the area with sanitary sewers. Results of the study showed that gravity trunk sewers flowing to a lift station that discharges to NEORSD's Sanitary Treatment Facility was the best option. KEM provided surveying services, basemapping, design and construction management services for the sanitary lift station and the initial gravity trunk sewers going into the lift station.
KEM conducted an evaluation of the existing Pheasant Run WWTP and collection system. KEM also conducted CCTV and flow monitoring of the existing collection system to properly produce a Preliminary Engineering Report to maintain compliance with “Findings & Orders” from the Ohio EPA. KEM evaluated all the existing processes of the treatment plant and formulated alternatives to achieve compliance with their NPDES permit. KEM developed capital costs and present worth values for each alternative. Taking cost factors, feasibility, construction, and O&M in to account, KEM developed a recommended alternative. KEM design of the recommended alternative is to be completed in 2017.
The Village of Butler is under “Findings & Orders” from the Ohio EPA and hired KEM to perform a Preliminary Engineering Report for the existing WWTP. KEM evaluated all the existing processes of the treatment plant and formulated alternatives to achieve compliance with their NPDES permit. KEM developed capital costs and present worth values for each alternative. Taking cost factors, feasibility, construction, and O&M in to account, KEM developed a recommended alternative. KEM is currently designing a new Sequence Batch Reactor (SBR) wastewater treatment plant for the Village. KEM is working with Village on a new location that allows for easy expansion to expand their customer base. KEM design of the new WWTP is to be completed in 2016
KEM was hired to complete and implement a general plan for sewage improvements to satisfy an Ohio EPA “Findings and Orders” stating that the current on-site sewage treatment systems were inadequate or failing. KEM initially prepared an engineering study evaluating alternative wastewater collection and treatment systems. A new gravity collection system containing 18,775 LF of sanitary sewer, and 2 pump stations along with a new package treatment plant was selected and designed.
KEM was hired to prepare a preliminary engineering report, perform grant work, final design plans, bidding services, and construction administration services for rehabilitation and replacement of equipment/processes at four (4) treatment plants throughout Lorain County to improve water quality standards. The four plants were: Eaton Homes WWTP – 200,000 gpd; Cresthaven WWTP – 80,000 gpd; Brentwood Lake WWTP – 120,000 gpd; and Plum Creek WWTP – 400,000 gpd. Improvements at each of the plants included: Electrical/Controls Upgrades; Tankage Rehabilitation; Addition of Tertiary Disc Filters; Addition of Aerated Sludge Holding Tanks to Improve Solids Handling Control; Disinfection Rehabilitation; Final Clarifier and Weir Trough Improvements; Blower Replacement.
This interceptor construction was the first phase of a three-phase program of improvements as recommended by the Elyria Facility Plan. The project design included 18,000 linear feet of 36-inch sanitary sewer, 2 sanitary lift stations and 2 critical crossings of the Black River. The project construction cost was $5,500,000.
A facility plan was prepared for the Village's existing WWTP which determined that several improvements were required to enhance the treatment performance of the plant and to deal with peak wet weather flow rates due to excessive inflow and infiltration in the collection system. Said improvements included a chemical feed system to meet new stringent effluent limits for phosphorus removal as required by the NPDES permit.
The goal of the project was to construct a sanitary collection/treatment system at an affordable user cost for a small community in Richland County, Ohio. KEM took an out-of-the-box approach with this prpoject due to the high cost associated with treating wastewater for a small number of households. Every possible treatment alternative was considered along with a cost analysis for each, with special attention paid to innovative designs that would help acquire additional grant funding.
