Neale Park Sewer Pump Station Upgrade
|Project Manager:||Nelson City Council|
|Time frame:||Until late 2018|
Update September 2017
A construction tender has been awarded to Downer NZ Ltd and site work is expected to start mid-September with completion by the end of November 2018.
Due to tight working space available in the area there will be some access and parking restrictions near the pump station site. The work site will be well fenced and please take note of any signage in place as construction progresses.
The upgrade will have significant benefits including increased pumping capacity for future growth, treatment of odour, and resilience to potential wastewater overflows.
Update April 2017
A tender for the construction work has been advertised on TenderLink. Tenders close on 1st June 2017 with an expected 3-week tender evaluation period.
Work could start as early as August 2017 subject to tender award. The construction programme is expected to be around 12months but contractors will have an available construction window and due date of completion extending to April 2019 to provide more flexibility in managing workload commitments.
Update December 2016
Detailed design has been completed and the resource consent is currently being processed. Tender documents will be put together in late January 2017. The tender period for the construction work will be eight weeks with tender evaluation in April 2017.
Work could start as early as May 2017 subject to tender award and an approved construction programme.
Update June 2016
Work is currently in the detailed design phase, with site investigation, geotech, survey and structural assessments completed. Construction plans are being finalised for tender, and a design report being prepared to support a resource consent application expected to be submitted late July 2016.
A tender for construction will follow and is expected to be awarded prior to Christmas.
This project is aligned with critical Council functions, protecting the health of the community and environment. Sewage from Bishopdale northwards is piped to the Neale Park pump station and then pumped to the Nelson Wastewater Treatment Plant along the state highway north of the city. Due to the distance, the pumps have to work at higher pressure and are not capable of delivering expected future sewage flows from planned city development. Upgrading to new pumps will ensure the system can cope with future flows.
Neale Park pump station was constructed in the late 1960s. All the original pumps have now been replaced, rather than repaired, as parts were no longer available. The site layout has contributed to ongoing odour issues in the immediate vicinity. A new pump station is proposed for the site, making use of the existing building, and incorporating modern odour control and some wastewater pre-treatment.
