Wastewater Treatment Plants
Glasgow Contractors is one of New Zealand's leading specialists in wastewater treatment plant pond maintenance, desludging and sludge dewatering. Relying on our specialist fleet of amphibious Truxor dredging machines, advanced dewatering systems, and purpose-built HDPE lined containment bunds, we safely remove accumulated biosolids from oxidation ponds, treatment lagoons and wetlands, without disrupting plant operations.
Oxidation Pond & Wetland Desludging
Glasgow Contractors’ lightweight amphibious dredging machines are easy to commission, low impact, and extremely effective at safely removing accumulated sludge from operational wastewater treatment ponds, lagoons and wetlands, without the need for pond dewatering or extensive excavations.
Our proven low-impact methodology minimises environmental disturbance, reduces disposal costs, and efficiently restores treatment capacity, helping councils and asset owners to improve compliance, treatment performance, and asset life.
Sludge Dewatering
Glasgow Contractors have extensive experience in hydraulically dredging and pumping wastewater sludge to dewatering bags, secured in HDPE-lined containment bunds, for passive dewatering and safe capturing and returning of filtrate to treatment ponds.
Through comprehensive sludge testing, conditioning, and optimised dewatering processes, we achieve high dry solid densities for cost-effective material disposal, helping asset owners reduce maintenance costs and improve compliance.
Containment Basin Construction
Glasgow Contractors have the in-house expertise, experience, and equipment to design and build suitable bunded dewatering containment basins, while working with trusted specialist lining partners to install HDPE (High-Density Polyethylene) liners.
