Wolverton Street Site Water Management
Who: Brian Perry Civil, MWN Civil
Products: PMXST05000 PMXBT25000MG PMXBT30000MG
Where: Wolverton Street Culvert
What: One of the challenges faced by Stefan at the Wolverton Street culvert construction site is dirty ground water which needs to be removed and cleaned to keep works running smooth.
Dirty ground water is pumped into the Promax Enduro 30000L tank, then is pumped via submersible pump into the silt screen to clean the water, then into the Promax Enduro 5000L tank as a settling tank.
Given the water restriction in Auckland, Stefan has an overflow high on the 5000L tank which al-lows full use of the 5000L for site use such as dust suppression, wiused with pilings, etc without drawing any from the Watercare system.
Smart move. Ground water which needs to be removed in any case is cleaned and re-used whilst the rest of the site water is put back downstream of the culvert as clean water.
