Installed SCADA System In All The Sump Room to Control Quantity Discharge by the member Unit
Quantity Monitoring
All the member units are given the discharge schedule for their registered effluent quantity to CETP. The quantity of effluent discharged by member units to sump room is governed by SCADA-PLC system.
No member unit can discharge the effluent to CETP more than their booking quantity, as either the discharge time or registered quantity is over, the valve provided in SCADA PLC will be automatically closed.
Quality Monitoring
All the sump rooms are equipped with Auto samplers for controlling quality of the effluent discharged by member units.
2Litres of composite effluent sample is collected in the bottle of specific member, which is equipped in the Auto sampler. The collected composite sample is irrespective of that member units’ discharge time and volume.
Every day, employee of monitoring department of CETP, empty the collected sample into the sample bottles and make 3 parts of the same. Then all 3 sample bottles are sealed at a time. Then immediately one bottle is given to the specific member unit, one bottle to GESCSL’s NABL accredited laboratory for analysis and 3rd one is preserved for joint testing (if member unit wants to after getting the result from our CETP). In laboratory, barcode is generated for each bottle and then analysis is performed. Result of the same is sent to the member unit through software based SMS system. If any member unit have query on the provided result then they have to intimate to the CETP within 48 hours of SMS. After 48 hours bill is generated through software based system.
In internal collection system, the gravity mains have a total pipe length of 17,588 m and sizes varying from 250 mm to 600-mm diameter. The rising mains have a total length of 6199 m and their sizes vary from 300 mm to 450 mm. Each member unit is required to arrange for pretreatment of the effluent meet the CETP inlet norms.
