Multimillion pound environmental works enter final stage

Scottish Water Meadowhead and Stevenson project

Scottish Water’s multi-million pound investment in environmental improvements to rivers and coastal waters in Ayrshire, one of the biggest projects of its kind ever undertaken in Scotland, started its final phase of work earlier this year in Kilmarnock.

Contractors MBV, working for Scottish Water, are starting the installation of the last 200-metre stretch of sewer pipeline along the river bed of the Kilmarnock Water from Howard Park to Cheapside Street as part of  a new storm water network between Irvine and Meadowhead Waste Water Treatment Works.

The final phase of the work, which is expected to be finished this summer, will complete a 500-metre stretch of waste water pipeline after. Work on this was stopped last October due to the weather and the salmon spawning season on the river, which runs from October to March.

The sewer pipeline will take storm water to the Meadowhead Waste Water Treatment Works via the North Lodge Pumping Station.

Mr Alastair Graham, Scottish Water’s senior project manager, said: “We are delighted to be starting the final phase of our work on this hugely important project.

“We completed our £30m investment in the Irvine area as part of this project in October and the new infrastructure there is fully operational and protecting the natural environment by minimising discharges of storm water to the River Irvine.

“When complete, our new storm sewer network in the Kilmarnock area will reduce the overflows of storm sewage in times of high rainfall and protect the natural environment of the Kilmarnock Water. It’s great news for the Kilmarnock area.”

To allow the work on the Kilmarnock Water to continue, MBV will re-establish a roadway made of hardcore stone from the river bank into the river at Wards Place.

This enables machinery used in the pipe-laying to access the river bed to excavate and lay new plastic pipe and then surround it with concrete.

The contractors will use sheet piling and pumping equipment to reduce the flow of water to a level that allows the work to progress.

Mr Graham added: “We will be using the same equipment that we used in the first part of the pipe-laying work in the Kilmarnock Water and we expect to make good progress and complete this work in about four months, weather permitting.

“Because we are working in the river, we will continue to closely monitor the weather and maintain a vigilant watch on the river levels.

“We have a sophisticated system in place which monitors water levels further upstream and alerts the contractors working on site in Kilmarnock of any sudden changes.”

Using CCTV, Enviro-Clean is responsible for the inspection of new pipes and the cleaning of the existing pipes, on the project. Enviro-Clean is helping to bring the entire system back to operational capacity and it is something which the company is very proud of.

Enviro-Clean Business Development Manager, Scott McCamley, commented:

“This is a very high profile project and it is great for us to be associated with joint contractors MBV.”

MBV have completed most of the work in Howard Park and are continuing the work on the new storm storage and pumping station facility at North Lodge near the A71.

Mrs Jane McKenzie, Scottish Water’s regional community manager, said: “The public in Kilmarnock will notice an increase in activity in and around the river bed of the Kilmarnock Water as we progress with this final phase of our work. We will continue to do everything possible to minimise any inconvenience and we will reinstate any areas affected by our work to the condition they were in before our work began.

“We again thank local people for their patience and understanding while we work on this project and we know they will appreciate that any short-term inconvenience will be far out-weighed by the long-term benefits this will deliver for the environment in the Kilmarnock area and beyond for many years to come.”

On all aspects, including new mechanical and electrical equipment, this project has involved close collaboration between consultants and Scottish Water’s supply chain- thus ensuring full compliance with the project objectives and regulations from SEPA.

Hydrok (UK) Ltd, a framework supplier to Scottish Water, are one such company who have provided the Storm Water Management equipment installed within the sewer network to regulate flows and screen the discharges from the necessary combined sewer overflows.

North Lodge pumping station is an example of one of the many Hydrok “Mecmex” CSO screen installations. Storm flows of up to 7000 l/sec are screened through 6 Mecmex screens in order to compile with the SEPA regulations prior to discharging to outfall. The screens were provided complete with Hydrok’s lifting systems to enable them to be removed from this deep chamber from above for inspections whilst ensuring the safe welfare of Scottish Waters Operations teams.

David Armstrong, Director for Hydrok (UK) Ltd commented: “As a long term framework supplier to Scottish Water for this type of equipment, Hydrok are proud to support this important environmental scheme.

“Hydrok are designers, manufactures and installers of specialist equipment for waste water and clean water management with a production facility in South West England where we manufacture all of our own equipment. We have been actively engaged with Scottish Water’s consultant engineers and delivery partners for many schemes across Scotland and hope to bring engineering solutions which are able to optimise designs and contribute to overall scheme cost and time savings whilst ensuring the strict compliance to the environmental and operational objectives.”
