Starting on September 15th, 2025, the County of Del Norte will conduct specialized testing of its sewer system through non-toxic smoke testing.Expect to see non-toxic smoke in the air and coming from the ground and sewer systems.Please make sure that you put at least 3 cups of water down each drain, toilet, sink, or any feature that drains to the sewer system. This will ensure that your p-traps are full which will prevent smoke from entering your residence or structures.#placement_573654_0_i{width:100%;max-width:550px;margin:0 auto;}var rnd = window.rnd || Math.floor(Math.random()*10e6);var pid573654 = window.pid573654 || rnd;var plc573654 = window.plc573654 || 0;var abkw = window.abkw || '';var absrc = 'https://ads.empowerlocal.co/adserve/;ID=181918;size=0x0;setID=573654;type=js;sw='+screen.width+';sh='+screen.height+';spr='+window.devicePixelRatio+';kw='+abkw+';pid='+pid573654+';place='+(plc573654++)+';rnd='+rnd+';click=CLICK_MACRO_PLACEHOLDER';var _absrc = absrc.split("type=js"); absrc = _absrc[0] + 'type=js;referrer=' + encodeURIComponent(document.location.href) + _absrc[1];document.write('');During the testing there will be field technicians on-site.
