Admerus Biosciences is a clinical research facility near Hyderabad, India. The facility hosts 200 research volunteers and some 50 members of staff who are using 36 toilets connected to two Aquatron separators. The two bio-chambers at Admerus were built onsite and separated flushing water is treated together with grey water in a reed-bed. This system has been in use since November 2018.\u00a0<\/em><\/p>\n The building was already under construction when Aquatron\u00ae was added to the plan but plumbing or STP-related work hadn\u2019t been started yet. <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n The Aquatron\u00ae-based STP at Admerus Biosciences research facility in Hyderabad was commissioned in October 2018. The system is based on two Aquatron\u00ae solid-liquid separators that stop faecal matter from mixing with the rest of the wastewater. In effect, this enables easy and cost-effective natural water treatment in a reed-bed and also allows the facility to reuse the wastewater for gardening or groundwater recharge through a percolation pit. The daily treatment capacity is 21 KLD and the eventual number of users will be about 250. The total cost for materials, construction and project management was about Rs 8 lakhs and the operating cost is limited to running a simple pump for about Rs 500 per month.<\/p>\n Execution<\/strong> Bio-chambers<\/strong> Plumbing<\/strong> Settling tank, reed-bed, hummus tanks and percolation pit<\/strong>
\nAs the first step, toilet locations were identified and the optimal way to connect the toilets to Aquatron\u00ae was decided. The dimensions of the bio-chambers and depths of underground pipes were determined and a reed-bed design was also drafted.
\nThe bio-chamber on the west side of the building serves 15 toilets and usage is expected to be light to moderate in this part of the building. The chamber volume is 2880 liters.
\nThe bio-chamber on the south side of the building serves 19 toilets and usage is expected to be high since it serves the volunteer accommodation area. The chamber volume is 4800 liters.<\/p>\n![](\"https:\/\/static.wixstatic.com\/media\/a7f937_50b26a84809d4bbe81ae28320c598f91~mv2.jpg\/v1\/fill\/w_390,h_213,al_c,q_80,usm_0.66_1.00_0.01\/a7f937_50b26a84809d4bbe81ae28320c598f91~mv2.webp\")

\nThe execution had three phases: Bio-chamber construction, plumbing work and reed-bed construction.<\/p>\n
\nEach bio-chamber, including the protective structure for Aquatron\u00ae, took about two weeks to complete
\nwith one mason and two labourers.<\/p>\n![\"Bio-chamber](\"https:\/\/www.aquatron.se\/wp-content\/uploads\/2019\/11\/screenhunter-594.jpg\")

\nPlumbing work for Aquatron\u00ae took approximately one man day to complete. It should be noted that
\nplumbing was done by connecting all WCs to closed-circuit lines without manholes. Most of the pipes
\nrun along the basement ceiling and any bends used (horizontal and vertical) were 45 degrees.<\/p>\n<\/p>\n
\nThe settling tank, reed-bed, two hummus tanks and percolation pit took approximately 21 man days to
\ncomplete<\/p>\n<\/p>\n
