Jul 20, 2011 Rainwater harvesting seminar attended by over 100 people

Over 100 people attended the rainwater harvesting technical seminar on June 23, 2011, co-sponsored by Washington Stormwater Center and CONTECH Construction Products. The half-day seminar started with some great presentations held at UW Tacoma campus, followed by a tour of the rainwater harvesting system and green roof at the Center for Urban Waters. If you couldn’t join us, links to the presentations are found below.

Greg Kowalsky (CONTECH) presented an interesting concept that I took away from the seminar. Greg discussed that traditionally the three areas of stormwater, potable water, and wastewater are often addressed separately within an organization. In other words, these three water management departments are often located in different offices with minimal overlap in their day-to-day work. However, as more sustainable projects become the norm – such as rainwater harvesting – these boundaries between departments are starting to blur. Check out Greg’s presentation for more about this. Do you have any examples how these three (or other) water management disciplines are starting to overlap in your organization?

  • If you have a rain barrel or hweover many under your gutter runoff you can collect water like that. When you have it full to keep mosquitoes out of it and to kill any mosquitoes in it, put a tablespoon of cooking oil on it and it will seal\' the surface of the water. Also, when you mow, keep your blade on a high setting and not give your lawn a crewcut; and leave the clippings, if they come out in big piles rake them around so they are evenly dispursed, like a little mulching. Try shredding some leaves very finely and spread this around also.Sprinkle your coffee and tea grounds on the lawn also. They will go right in, but son\'t do this all the time or it will make your soil acidic.I could go on and on, but that\'s a start .
