## Description
Supply (including design, assembly, supply, delivery and co-commissioning) of an integral modular primary and secondary treatment system(s) to be implemented as sidestream solutions at multiple sewage treatment works (STWs) across AMP8.
Severn Trent Water requires integral solutions - primary settlement, biozone/ biological treatment and humus/ final settlement - all to be contained within a singular modular 'roll on roll off' unit - with lifting points for cranage where required. 
Potential for a limited number of alternative configuration units may be required depending on site requirements - e.g.) biozone only, biozone + humus settlement zone, primary settlement + biozone. 
The units required are to be deployed at small to medium size treatment works. With the aim being to install an independent side stream to increase the treatment capacity. Allowing for an increase of Flow to Full Treatment (FFT). The flow will be proportionally distributed between the existing assets and modular sidestreams based upon the maximum treatment flow.
•	Solution can be either SAF or MBBR
•	Automated sludge removal is to be provided from the humus and primary zones.
•	Adjusted aeration is to be provided to the biological treatment zone, to allow for optimisation and scouring (as required).
•	Lamella units are not a preferred settlement process (for primary or humus), due to previous operational issues requiring excessive operational intervention.
