The Tribune (NZ) - - SQUARE CIRCULAR -

Coun­cil trade waste of­fi­cer Mike Sa­hayam has scooped a top sci­ence award in recog­ni­tion of his work at Palmer­ston North's To­tara Road Wastewater Treat­ment Plant. The award was recog­ni­tion for his work on im­prov­ing the qual­ity of wastewater dis­charged into the Manawatū River.

Mike, who pre­sented two pa­pers on his work at the In­dus­trial Wa­ters NZ Con­fer­ence in Christchurch, says if the plant re­ceives cleaner ef­flu­ent, then it costs less to treat and clean the ef­flu­ent be­fore it’s dis­charged. “Ivvvn­dus­tries im­prove their dis­charge, every­one is re­spon­si­ble.”

The an­nual con­fer­ence is for mem­bers of the New Zealand Trade and In­dus­trial Waste Fo­rum - a net­work­ing or­gan­i­sa­tion de­signed to get reg­u­la­tory au­thor­i­ties, util­ity oper­a­tors and re­gional coun­cils all in the same room to dis­cuss is­sues like trade waste, stormwa­ter, haz­ardous waste, wa­ter re­use and min­imi­sa­tion sys­tems.

In­dus­tries play a big part in the qual­ity of ef­flu­ent dis­charged and Mike says the Coun­cil now has the tech­nol­ogy to ‘finger­print’ trade waste. By iden­ti­fy­ing the dis­charge the Coun­cil can talk to the in­dus­try con­cerned and get them to im­prove their waste wa­ter dis­charge.

It’s re­ally the re­spon­si­bil­ity of every house­hold to en­sure what they put down their toi­lets is kept to the three ‘P’s’ only, poo, pee and pa­per. Wet wipes and dis­pos­able wipes should not be flushed at all." he said. “They cause a lot of net­work block­ages. House­holds can also help by making sure that fat is not put down sinks as it’s one of the most ex­pen­sive con­tam­i­nants to re­move from the waste wa­ter.” Mike said an­other on­go­ing prob­lem was the use of phos­phates in laun­dry pow­ders and dish­wash­ing de­ter­gent. “We should all make the ef­fort to go phos­phate free when it comes to de­ter­gents and laun­dry prod­ucts. It would save con­sid­er­able time and money in re­mov­ing phos­phates when the dis­charge reaches the waste wa­ter treat­ment plant.”

The 2017 con­fer­ence will be held in Palmer­ston North.
