Levin Water Treatment Plant Upgrade
Horowhenua District Council
Circa $3 Million
15 ML/d Maximum 3.6 ML/d Minimum
FILTEC was contracted to design and upgrade an existing non compliant water treatment plant that supplies Levin.
What We Did
FILTEC’S design included the installation of Actiflo clarifier chemical dosing, a Wedeco UV reactor, bulk chemical storage and chemical unload pad. A new chlorine dosing system was installed, along with a chlorine storage building with a storage capacity of 8 x 1 tonne chlorine drums on a rail system. All chemical storage and dosing had to meet HSNO requirements. An advanced oxidation system was also installed – only the 3rd treatment plant in New Zealand with this system.
FILTEC upgraded the plants control system and had to integrate the existing plant into the new PLC and SCADA system without disrupting the supply of drinking water to Levin.
