Wastewater Treatment Plant Upgrades
New solids handling equipment was installed to improve treatment, safety, and efficiency at our Wastewater Treatment Plant (WWTP) over the last few months. Wastewater flows include paper products, such as toilet paper, and other solid materials that we normally remove from the water prior to the biological treatment process. The WWTP Screening Upgrades included a new in-channel grinder at the headworks (where flows enter the to remove these solids and deposit them in a dumpster where they are then transported to the local landfill. The contractor, Foley Mechanical, performed the installation and removed the existing equipment which has a recent history of failures. Project Cost was $120,000.
Work has begun on one of the clarifiers, large basins used for treating water prior to discharge in the Kansas River. The concrete floor of the clarifier requires rehabilitation and we plan to overall the main drive that operates large rotating equipment within the clarifier. Painting of the metal structure components is also planned. The WWTP has two (2) clarifiers so operations are not impacted during this work. Estimated Project Cost is $80.000 - $100,000
Both projects are managed by Department Staff with assistance from our City Engineer.
Storage Tank Painting
Painting work has begun on one of our 1 million gallon storage tanks (ST1) to restore interior paint protection. The tank was cleaned and a section of the exterior was painted last fall. It was during this process that we discovered severe paint delamination on the roof panels and upper side wall sections and subsequently scheduled the repainting process. The tank was constructed in 2000 and normal life expectancy for industrial paint is 20-25 years, so since the tank was in its 17th year, repainting the interior provides the best solution rather than just painting the roof area.
The Contractor expects to have the painting completed by early June. Some additional work was required to ensure that this vital infrastructure structure will provide reliable service for the next 25 years. Storage Tank maintenance is a routine part of ensuring sustainability for the Water Distribution system.
We plan to have the tank back in service before July 4th. Extensive testing is required after the painting process to ensure safe Drinking Water. Estimated Project cost is $100,000.
We have two (2) one-million gallon water storage tanks; the other tank is scheduled to be cleaned and inspected in the fall of this year.
New Pressure Control Valve Installations
The Department's contractor, Schuetz Construction, Bonner Springs, KS, has begun work to install two (2) new Pressure Control Valve (PRV) facilities within the northern pressure zones of our water system. One PRV facility will be constructed on 134th Street, just south of I-70 to control flow on an emergency basis between the north pressure zone and central pressure zone.
We regulate flow and pressure when needed during high demands to ensure that our residents maintain acceptable water pressure, especially in cases of a waterline break. The other PRV facility will be installed in the far northeast section of the north pressure zone where we have an interconnect with Board of Public Utilities (BPU) water system. This PRV will provide flow control from the BPU system during an emergency situation or if high demands require additional water flows.
These PRV facilities are being installed to improve water supply sustainability thus ensuring that water can flow freely from our emergency interconnects with BPU. The central and northern pressure zones are maintained by pressure regulated pumps located at our storage tank facility. If the pumps were to fail, for any reason, the PRV facilities will operate automatically to maintain flow and pressure into these pressure zones.
Total Project Cost for both PRV facilities = $125,000
Replacement Waterlines (Scheduled - Summer 2017)
We have delayed this large waterline replacement to make additional infrastructure improvements in the area. Besides replacement of old
The Total Estimated Project cost is $800,000 to replace 3500 feet of pipe and the associated service lines to the meter service for each house, including new meter pits; new sidewalks, improved stormwater inlets and street repaving. Once completed, this new construction will provide years of reliable water service for residents, safe walking, and good roads. Eventually, the entire area in this section of the City will have similar work completed to provide clean, safe drinking water walkable areas and safe, good roadways of the citizens of Bonner Springs.
