Site visits

We will anchor the research and innovation presented in the two day conference by providing the opportunity to see how this is put into practice at some of the key WWT plants in and around the City of London. Delegates will get the chance to see fully working plants and learn about the history of WWT in the UK and London.

Site visit 1: Crossness WWTW

Wednesday 12th July 2017

1280px-prince_consort_crossness_pumping_stationThe historic Crossness pumping station, the “Cathedral on the Marsh,” will be our base for the day. Designed by Sir Joseph Bazalgette and constructed in 1859, it features spectacular ornamental cast ironwork and a fully restored steam beam engine, the largest of its kind in the UK. The steam engine will be in steam during our site visit operated by the Crossness Engine Trust

One of the largest sewage treatment works in Europe, Crossness treats an equivalent population of 2 million people and produces 140 tonnes of dry sludge per day. It utilities thermal hydrolysis pre-treatment with 3 x 2MW of electrical generation and will soon be demonstrating an Advanced Energy Recovery process post digestion.

The day will include: 

  • An introduction from the Site Manager
  • A tour of the Thermal Hydrolysis Plant;
  • A tour of the Advanced Energy Recovery Plant under construction/commission;
  • Lunch will be provided in the Crossness Pumping Station, a magnificent Grade 1 listed Victorian building;
  • A chance to see the ‘Prince Consort’ steam engine in action.

Delegates will need to bring their own site boots for the visit, failure to do so will mean you will not be permitted on the tour. All other PPE will be provided. A coach will take you from Imperial College and return you there at the end of the day.


Site visit 2: Reading WWTW

Thursday 13th July 2017

Reading site visitThis is a very modern site which is only 10 years old, treating a population equivalent of 250,000. The site processes about 25 tonnes of dry sludge per day using anaerobic digestion with CHP. Get a behind-the-scenes look at the Reading plant with a photo tour by Nathan Hyde.

Extensive THP and AD research is being undertaken at lab scale including bench scale dewatering, recovery & utilisation of Fat Oil & Grease. The visit will be hosted by the Thames Water Innovation Team, who make ‘cool stuff happen.’ Update: we will also visit Basingstoke WWTW in the afternoon.

 The day will include: 

  • An introduction from the Innovation Team;
  • A tour of the entire treatment process on the Reading site;
  • A tour of the Innovation lab and pilot facilities;
  • A tour of the various demonstration facilities operational on site;
  • Lunch will be provided in the Innovation room.

Delegates will need to bring their own site boots for the visit, failure to do so will mean you will not be permitted on the tour. All other PPE will be provided. A coach will take you from Imperial College and return you there at the end of the day. There will be a dropoff at Heathrow Airport at approx 5pm on the journey back for those who need to travel home.
