Waste Water Treatment Plant Schedule

Izam,
It depends on the design and locations of Waste Water Treatment Plant.

Critical activities varies on design, lead procurement items like mechanical equipments, aerators, pumps, cables, generators, clarifiers equipments, grit & screen, piping materials, structural, handrails, platforms, tanks, media filters,valves,Penstocks & Stop Boards, SCADA, PLC, Switchboars etc … and construction methodologies and commissioning, service proving, operator trainings and many others.

If designs consist of Waste Treatment plant, Recycle Treatment, Class A & Class B storage tank or lagoon then all of those have different criticality, especially on long lead items that mostly takes 3 to 6 months and if not available in the country then it will take more if coming from overseas.

Typical Items are:
A) Common Facilities:
1.     Earthmoving
     Bulk Earth works & Earth moving & backfill
     Landscape
2.     Civil Works
     Roads and pavements
     Roads Hardstand & Guardrails
     Permanent Fencings
3.     Mechanical Works
     Some mechanical equipments
     Underground piping
     Potable water piping
4.     Electrical & Communication Works
     Lighting Protections
     Area, Road Lightings & Flood lights
     Site lighting and small power
     Security Access & CCTV System
B) Waste Treatment Plant and buildings
1.     Inlet Structure
2.     Screening & Grit
3.     Balance Tank, Bioreactor & WAS pump
4.     Blower
5.     Clarifiers
6.     RAS Pump Station
7.     Dual Media Filter & Filtrate Storage
8.     Waste Buffer Tank & Pump Station
9.     Chorine Contact Tank
10.     Chemical Storage & Unloading
11.     Lime Storage & Unloading
12.     GPPS & Tanker Receival Pump Station
13.     Tanker Receival Facilities
14.     Electrical Building and Facilities
15.     Sludge Dewatering
16.     Odour Control Facilities
17.     Control Buildings
18.     Workshops
19.     Tanker Loading Area

If Recycle water treatment plant is also included then another major items like Ultra Filter, Switch room, UV disinfections etc…
It may include Storage tanks or lagoon and Pump Stations.

Hope this help.
