North Waltham waste treatment plant is a UK first to have pioneering new technology
A WASTEWATER treatment works in North Waltham has been refurbished with new equipment that is among the first to be used for this type of treatment in the UK.
Engineers have installed new treatment tanks containing “good bacteria” that feed off the germs and chemicals in the wastewater as it flows through.
Southern Water, which is responsible for the works, says it provides an extra stage of treatment, without the use of chemicals, meaning the wastewater leaving the site is the best quality.
The existing treatment works is small so specialist tanks were used to carry out the improvements without expanding the size of the works.
Heather Barber, senior project manager, said: “The existing works has always provided good treatment but the new scheme has been designed to remove nitrates as well. These can find their way into the water through the large scale use of fertiliser which can run into the sewers during heavy rain.”
The treatment works serves a population of around 1,000 and can treat up to a quarter of a million litres of wastewater per day.
The £3.3million scheme will ensure Environment Agency standards are met.
It is being carried out by contractor 4Delivery which is carrying out £40million worth of other similar schemes in north Hampshire, including in Whitchurch and Overton.
