MWH Bleached, Barred & Blasted

Regarding current MWH activity in Cape Coral...

The Nattering One has cultivated some unique sources over the years.

This time we have come across some inside information that needs to be shared with the public.

Please bare in mind that in all three of these cases, city employee's at both plant's...

have been adamant in their complaints about MWH's lack of engineering and refusal to rectify the situation that MWH directly caused.

Peroxide Blonde Design?: Both Everest & SW water reclamation plants have a malfunctioning sodium hypochorite (bleach) system & untenable bleach building's.

The skids where the VFD's (variable frequency drives) & pumps sit are a maintenance & operational nightmare.

VFD's were placed directly on the pumps, on the ground, open to the elements (rain) and separated by only 6-8" inches.

Because of the spacing and due to the pump/drive combo positioning the skids are almost impossible to maintenance or repair.

The VFD's & pumps are not even water resistant, so last year, 8 of 10 pump drives failed with the first seasonal rains.

Next to monitoring for dissolved oxygen, sodium hypochlorite levels are extremely critical to the process of reclaming waste water for safe public use.

These buildings and pump skids are a $750K disaster that MWH still refuses to take ownership of and insists that the city must pay to rectify.

Bar Screens: MWH replaced perfectly functioning 2 year old bar screen systems at both Everest & SW.

The new bar screens cannot perform allowing large clumps of debris to enter each plants process...

causing both plants massive deragging and maintenance problems downstream.

True Grit Blast? The grit system at SW Reclamation can only capture 45% instead of 95% of the grit as guaranteed.

The vendor was the only vendor which would guarantee 95%, the same vendor whose "teacup" systems failed miserably in the Cape a few years ago.

The system failed the initial test, so the vendor hired an “outside” firm and claimed passage of a dubious 2nd test.

City employees witnessed the 2nd test failure, nevertheless, MWH stood behind the vendor’s vailed legal threats.

Excessive grit entering the system would not only cause excessive downstream maintenance and process issues...

but it would also cause premature catastrophic failure of the new biosolids centrifuge systems at SW reclamation.

More to come on the Southwest Biosolids fiasco in our next post.
