We have the same phenomenon [storage tunnels for combined sewage] in Toronto
too and the current plan is to build more. These tunnels will also increase
the amount of sludge that has to be dealt with.

> Described as 'blending'
> As recently as last week, district officials described the incidents as

> sewage was partially treated.
>
> The dumping in question occurred in 2004 on March 28, June 19 and June 21

>
> During emergency situations - such as heavy rain - the district is allowed
> to dump up to 60 million gallons a day of sewage that skips a portion of the
>
> treatment process to avoid releasing sewage that has no treatment or to
> avoid the damage that sewage backing up in homes or overwhelming the
> treatment system would cause. The process is commonly known as blending.
>
> "It was definitely not blending," said Charles Burney, a top state
> Department of Natural Resources official who oversees the district. "It
> didn't meet any of the conditions in their permit."
>
> But Burney struggled to describe exactly what happened because a "glitch" in
>
> the district's 66-page permit never anticipated such an event.
>
> Thus, the DNR was not able to cite the district for the dumping, he said.
> Instead, the DNR issued a letter in December 2004 reprimanding the district

>
> The state Department of Justice brought a lawsuit against MMSD regarding the

> "blending" events were not included in the lawsuit.

> Both MMSD and officials from United Water maintain that the mere mixing of
> the undiluted waste with the treated effluent constituted blending.
>
> "What happened was disclosed," said John Cheslik, the United Water project
> manager in Milwaukee. "It was all in a document that was sent to the DNR."
>
> Four members of MMSD's governing commission - Cole, West Allis Mayor
> Jeannette Bell, Rep. David Cullen (D-Milwaukee) and Rep. Pedro Colón
> (D-Milwaukee) - apparently never got the document. They said they understood

>
> While Burney described the three incidents as dry weather events, John
> Jankowski, the MMSD official in charge of making sure that United Water
> complies with its contract, said it was raining on two of the days.
>
> The flow at the treatment plant was at its highest on June 19 at 120 million
>
> gallons, less than half of its capacity of 300 million gallons a day.
>
> As much as 10% of the daily flow received no treatment other than
