Geocache Description:

You are looking for a small clip lock box. Nettles may be a problem in the summer - we will go back and check it out should the weather ever improve! The local atmosphere may act as a fertilizer!

Wantage Sewage Treatment Works

This treatment works serves the communities of E & W Hanney, Grove, Wantage, Denchworth, E Challow, E & W Hendred, Kingston Lisle, Childrey and Letcombe Regis, and has a capacity to serve a population equivalent of 25,900.

The pumping stations pump sewage to the Inlet building. Sewage entering the inlet well passes first through a very rough filter to remove large objects. It is then lifted up by three large archimedes screws to the inlet screen. This removes objects larger than 6mm. The filtered sewage then enters a
settling tank where grit settles out.
It then goes to one of the three primary sedimentation tanks. The sediment is scraped from the bottom and removed for pressing. The pressed sediment (cake) contains about 30% water and is taken by lorry offsite. It is mixed with hydrated lime to ensure a balanced ph and then can be used as fertiliser for non food crops.

Sewage is then sent to one of 12 rotating biological filters. These contain porous rocks which contain bacteria that feed on the sewage. This produces a liquid with very fine solids. The bacteria growth is temperature dependant and if the water temperature is very low the bacteria growth is reduced. The majority of sewage pipes feeding the Wantage works are below ground and so the sewage tends to maintain a high temperature even in very cold weather.

The sewage is then sent to one of 4 final sedimentation tanks and is finally discharged to Letcombe brook via the outfall.

The cache is located off the footpath. This path is not suitable for wheelchairs, but all terrain buggies should be ok if it is dry. There is excellent blackberry picking opportunities here in season!
