Nelmac offers wastewater management for local government and commercial businesses.

By treating wastewater, we help to preserve water resources, aid economic growth, protect the environment and improve communities. Nelmac offers the following wastewater treatment services:

  • Collection – through a network of pipes and pump stations, wastewater is conveyed to the treatment plant. Collection systems are maintained regularly to prevent blockages and overflows
  • Treatment – we operate and maintain treatment plants to treat the wastewater to a suitable standard to re-introduce into the receiving environment. This involves a combination of treatment stages of variable complexity depending on the scale and , sensitivity of the reinduction process.
  • Disposal – after processing at a treatment plant, wastewater is returned to the environment in a way that does not adversely impact environmental balances.
  • System management – optimising plant operations, training operators, process start-up and commissioning, equipment analysis and evaluation, and best treatment practices

Nelmac operates and maintains two treatment facilities in the Nelson / Tasman Region, Nelson North Wastewater Treatment Plant and Bells Island Wastewater Treatment Plant. We employ over 15 staff to maintain, operate and provide qualified sustainable results.

“IN UNDERTAKING ITS ROLE IN OPERATING AND MAINTAINING THE BELL ISLAND WASTEWATER TREATMENT PLANT, NELMAC HAS ENDEAVOURED TO NOT ONLY FULFIL ITS CONTRACTUAL OBLIGATIONS BUT IDENTIFY AND PROMOTE THEIR INITIATIVES THAT COULD IMPROVE EFFICIENCIES AND EFFECTIVENESS.
THIS TYPE OF APPROACH FROM A CONTRACTOR IS VERY REFRESHING.”
