Case "Evansdale": 7 Options to Update a Wastewater Treatment Plant
Published on by WWTP Designs Research, Contributing Editors in Technology
The City of Evansdale is facing a serious decision on how to upgrade their old wastewater treatment facility due to the lack of flood protection, as well as disinfection.
The City is currently reviewing seven options:
- Rising the structures of the existing wastewater facility above the five-year flood level, installing a higher access road, putting in a remote operating system and installing a disinfection system;
- All the above, plus making sure to meet nutrient reduction goals, lowering the city’s current nitrate and phosphorous loads going into the Cedar River sludge with a sequencing batch reactor;
- Same as no 2, yet by utilizing aerobic granular sludge (a 30-year-old European technology not yet approved by the Iowa DNR);
- Building a brand-new wastewater treatment plant at a new location with the old sludge technology;
- Building a brand-new wastewater treatment plant at a new location with the new sludge technology;
- Scrappibg Evansdale’s plant, building new pump stations and hooking up their infrastructure to an existing plant;
- Hooking into the already-combined Elk Run Heights/Raymond plant.

The UN flood mitigation program still seems the best route to follow. First of all people measure floods by how high they are recorded and call it a FLOOD Plain. But now most people can do simple math and calculate how many gallons of water are at that flood time. Just need to plant sufficient number of trees bushes etc. to rapidly drink (respire) the water. You can do the math in your head with no calculator. The average size tree will drink and respire up to 300 gallons of water a day. This natural process is now being used in deserts to retain their flood water and increase humidity creating new farmland and later forestry.
