This was the first contract signed by PeopleService in December of 1988. Since this project started, PeopleService has jointly worked on numerous system improvements with the city including water system control upgrades, lift station upgrades, well rehabilitation, chemical feed system, and many other improvements and studies. Most recently the wastewater treatment plant was upgraded and after careful research by the city and PeopleService, a new aeration system was installed. This new type of aeration is a vacuum bubble technology and is one of the first in the state. PeopleService spent considerable time working the Iowa DNR to get this new system approved. The system was first installed on a study basis in October 2001 and installed permanently in the summer of 2005. Other improvement to the WWTP at that time included a new raw pump station, electrical system, and control building. This type of aeration has saved the city hundreds of thousands of dollars by biologically removing the biosolids as opposed to mechanical removal.

The water plant came on line in 1995 when the city lost its water superintendent and did not have a properly certified person to run the system. Since 1995, the town has operated with 6 PeopleService employees to operate and maintain the water and wastewater treatment facilities plus the collections and distribution systems. This is done with 5 less employees than the city operated the two departments with. In 1996-97, we oversaw the wastewater plant upgrade to its current capacity. In 2000, the wastewater lab became certified and continues to receive high marks for its quality and procedural controls. In 2004, PeopleService helped with the planning and design processes for a new 2.4 MGD water treatment plant. The city continues to rely on PeopleService for all its wastewater and water needs and we have developed a partnership that is beneficial to both parties.

Project Summary:

Elkader, IA became a client in December of 1989. Elkader is located in northeast Iowa and nestled in a very hilly area. In early 2003, the city began planning on water system improvements to replace their over 60-year-old water treatment plant and part of the distribution system. PeopleService worked closely with the engineering firm to help plan and design the new system. In December of 2005, the new system went on-line. The 2 million plus dollar project consisted of two new wells, new water treatment plant, new water storage tower, 11 pressure reducing stations, over 100 home pressure reducing valves, $400,000+ worth of water main replacement as well as numerous new valves and hydrants. Construction had to be phased in as the new and old system had to be integrated in order to provide water to all citizens. During construction of the water system improvements, the city, PeopleService, and engineers began plans for a sewer system improvement project to be started in 2006 to include numerous blocks of sanitary sewer replacement and new mains. Due to a flood and to avoid future concerns three of the lift stations have been replaced/rebuilt and one new one added. In 2010 the city of Elkader started up a new .800 MGD Aero-mod Activated Sludge Plant with a Siemens vertical UV unit being used for disinfection. The headwork’s room includes a Vulcan step screen, Vulcan grit chamber and Smith and Loveless grit classifier. During the upgrade project a lagoon cell was converted to a storm retention pond and another cell was converted to a sludge storage pond. The entire water and wastewater system is operated with a SCADA system.

PeopleService assisted the city in establishing guidelines for selection of an engineer to design a new treatment plant. In December of 2000, a new 2.7 MGD Bio-Lac activated sludge plant went on-line with reed bed sludge handling and a 3 million gallon equalization basin. The Humboldt system also has 4 lift stations and a primary main lift station. Since 2000, three of the lift stations have had major upgrades or replacement. Numerous sewer system lines have been replaced or rehabilitated with cured-in-place pipe liners. PeopleService has helped establish private sewer service standards and completion of a major sump pump inspection program. The water system was added in 2009. It consists of a 2.3 MGD lime softening plant, two 500,000 gallon water towers, and the distribution system. Humboldt uses two water sources, one well and one spring. In 2011, the Iowa DNR reclassified the spring source as under the influence of surface water. We assisted the city of Humboldt with the upgrade of the water treatment plant to meet the Surface Water Treatment Rule.

Project Summary:

This project began in November 2013. Warsaw is located at the beginning of the Ozarks in central Missouri on the Truman Reservoir. The city has two wells with chlorination and fluoridation and an SBR WWTF. Warsaw was in need of a water and wastewater superintendent and hired PeopleService to manage its water and wastewater systems. The city is facing several issues as a result of an aging infrastructure that is limiting its ability to grow. Warsaw was also facing several budgetary issues due to declining revenues. PeopleServcie helped the city review its water and wastewater ordinances and have actually increased revenues. A valve turning and preventative sewer jetting program are being implemented and we are assisting the city with its water master plan to facilitate growth. Warsaw was also experiencing severe I & I issues and plugging issues at the WWTP due to people flushing baby wipes and other items that should be thrown away instead. PeopleService is working with the city to implement an I & I reduction strategy. We have worked with the city to educate the public about what can and cannot be flushed into the collection system.
