WPL lands contract for wastewater treatment at Ebbsfleet
Oct 25, 2017
Package treatment specialist WPL has landed one of its biggest-ever projects - to build the wastewater treatment plant for Castle Hill, Kent – the first phase of the Government’s new garden city to be built at Ebbsfleet Valley. The new town of Ebbsfleet is one of the most important developments in the south of England, with plans to build 15,000 new homes for a planned population of 40,000.
Multi-utility provider Metropolitan was awarded the contract to deliver services for the 1,500-home Castle Hill development by Landsec. The agreement includes installation of a new onsite wastewater treatment works for 4,000 population equivalent (PE).
Metropolitan appointed Alpheus, a specialist in water and wastewater asset management and design, to provide the plant. WPL is working in partnership with Alpheus to deliver a flexible system to serve the homes, businesses and amenities currently under construction. The new wastewater treatment works is being built in two stages and WPL is supplying a total of 16 above ground WPL Hybrid-SAF submerged aerated filter package treatment units along with primary lamella clarifier units, final settlement tanks, blowers and the air lines.
Prestigious development
WPL technical director Andrew Baird said: “This will be one of the largest installations WPL has built from start to finish and our biggest contract to date for the Hybrid-SAF. It is a very prestigious project – particularly as it involves the creation of Ebbsfleet new town.
“WPL has been discussing plans with Alpheus for three years to ensure the new plant will meet the requirements of the first inhabitants of Castle Hill. Given the long-term vision for the development, it is important that the plant optimises the footprint available and is flexible to accommodate a growing population.”
At present, effluent from the homes and commercial properties in the Castle Hill development is collected in a storage tank and transported away by tanker. However the town, which is 17 minutes away from central London by high-speed rail and situated on the High Speed 1 service to continental Europe, is set for rapid expansion.
In the March 2014 Budget, the then Chancellor promised 15,000 new homes in Ebbsfleet. New retail, business, leisure and commercial facilities along with schools and healthcare provision are expected to create up to 20,000 jobs.
Two-stage build
The first stage of the new treatment works which will serve 2,000 PE has been completed and comprises one primary lamella clarifier, eight Hybrid-SAF units connected in series and the final settlement tank. The second stage, on which work is expected to begin next year, will expand the plant to serve 4,000 PE.
Andrew Baird explains: “The existing storage tank is adequate to serve the homes constructed during phase one of the Castle Hill development, but by late 2017 there are expected to be over 1,000 people living there. At this point, WPL plan to move on to stage two, to be built alongside stage one, which will comprise a primary lamella clarifier, sludge storage tanks, eight additional WPL Hybrid-SAF units and an additional final settlement tank.”
The area has protected groundwater so the Environment Agency stipulated that the new treatment plant had to be installed above ground. The plant will release wastewater treated to the high standard required by the Environment Agency into the Thames Estuary.
WPL installed the first stage of the plant in the spring of 2017 and it will become operational by late summer. Both phases of the plant are being manufactured offsite at WPL’s specialist facility in Waterlooville and delivered, installed and tested by WPL engineers. The project’s quick turnaround will keep costs down for the customer as minimal civil engineering is required for installation onsite.
In the future it may be decided to connect the Castle Hill development to mains sewerage, but at present none nearby have sufficient capacity. The modular configuration of WPL package plant has been designed to be highly flexible and will serve the town as it expands.
Easy installation
Andrew Baird said: “WPL has been manufacturing package plants for 25 years, both for industrial users and for utilities, and is well known for building plants which are robust, durable and easy to install and maintain. The company has a longstanding relationship with contractor Alpheus and has worked closely with them to design a plant which can serve the new city well.”
Metropolitan Director, John Marsh said “Metropolitan has worked with Landsec to provide a multi-utility solution for the site and the provision of all its essential connection requirements. Finding a cost-effective solution for the treatment of wastewater has led Metropolitan to install the onsite WPL Hybrid-SAF plant – which meets the entire needs of the Castle Hill development and will be delivered on time and to budget.”
Declan Maguire Operations Director of Alpheus, said, “We are delighted to be involved in such a significant project, which draws on Alpheus’ expertise in design and build projects. The modular design of the Ebbsfleet plant means it can be built in two stages, which will provide the necessary wastewater treatment as new homes are built and the garden city expands.
“The first phase is due to finish in the autumn. We hope to be involved in future developments at Ebbsfleet.”
WPL Managing Director Gareth Jones said, “We are delighted to have been selected to provide wastewater treatment for the Castle Hill development at Ebbsfleet. The developer’s need for flexibility and reliability in a compact footprint makes WPL’s packaged treatment systems an excellent match for this project.
“The Government has said it wants to build a million new homes by 2020 and we are already receiving enquiries from other housing developers considering the WPL Hybrid-SAF in their plans for wastewater treatment.”
