Gorman-Rupp has shared a series of videos (about 20 minutes in all) describing and showing operations and maintenance tips and guidelines for the Super T Series of trash pumps. With hundreds of these pumps in operation across Iowa and Nebraska, we are pleased to share these videos with you:

Planning ahead for algae control in ponds and lakes
May 15, 2012
We offer an alternative option: Pond aerators and fountains, which can be used not only to provide a combination of air and agitation (which help to inhibit the growth of algae), but that can also be combined with a simple lighting system to provide an attractive landscaping feature. Please feel free to contact us with your questions.
This highlights the importance of stormwater management. Good stormwater management is a tricky subject for many communities: It requires a lot of spending on infrastructure as an insurance policy against a low-frequency but high-impact event. (Big flash floods don't happen often, but when they do, they often affect lots of people and do lots of damage.) That can make it difficult for elected officials to risk their political futures by asking taxpayers to invest in stormwater management, since they aren't likely to be hailed as heroes for having done the right thing -- if a stormwater control system works right, few people are going to acknowledge the foresight of the planners and officials who implemented the controls; they're only likely to punish those who appear to be at fault if something goes wrong. This is an important industry issue for the water/wastewater sector, and one with no obvious "magic bullet" solution.
One of the major hassles of monitoring chlorine in water systems is that it's a labor-intensive process if you have to use test strips, and it can require lots of expensive reagents if you use some of the better-known automatic monitors.
ATI makes a better, easier-to-use type of chlorine monitor -- good for free chlorine and for combined chlorine (chloramines) -- that requires no reagents. It monitors continuously and has 4-20 mA outputs for relaying the information to any kind of standard control system you use. It's simple and compact, as you can see from this recent installation:
USDA will take some extra acres for conservation this year
May 29, 2012
The USDA is planning to accept about 100,000 acres of Iowa farmland into the Conservation Reserve Program this year, marking an increase of about 13,000 acres over the number whose leases with CRP will expire this year. The program is used for a number of purposes, though it's largely intended to help prevent environmental damage by providing a buffer between waterways and soil that's been treated with chemicals, fertilizers, and manure. Doing that helps reduce the volume of nutrients that enter the nation's waters, which contribute to a number of problems -- including nitrates in drinking water and algae blooms in lakes. The dead zone in the Gulf of Mexico is also blamed on the nutrients in fertilizers and manure. Because the CRP leases last for 10 to 15 years, they represent a big investment for farmers, who exchange the certainty of their CRP payments for the uncertain amounts they can make from raising crops or grazing livestock.
FYI: The "dead zone" is caused by hypoxia, which is the lack of dissolved oxygen in the water. Many municipal wastewater treatment plants have to measure for dissolved oxygen in their treatment processes to help ensure that they don't discharge "dead" water into receiving rivers and streams.
