Springs of sewage on roads resulting in  OMR in Navalur

There isn’t a formal underground drainage system in areas alongside the stretch of Previous Mahabalipuram Street (OMR), from the positioning of the erstwhile Navallur Toll Gate to the Siruseri Sipcot. As a substitute, an eight-inch rainwater-carrying pipeline on Vembuliamman Koil Avenue, which runs parallel to this stretch, is being misused for discharge of sewage by way of unauthorised connections. The consequences of this wilful misapplication could be seen on the service lane of OMR. Within the absence of an underground drainage system, particular person homes, gated communities, business institutions reminiscent of PG hostels ought to preserve septic tanks and have sewage lifted by way of personal sewage-clearing lorry companies.

Residences within the space preserve Sewage Therapy Vegetation (STPs) and use sewage lorries to clear their septic tanks, however PGs are derelict of their respobsibility by bypassing these processes.

Many PG hostels and particular person homes have related their sewage retailers to this pipeline. By design, these pipes discharge into OMR’s service ducts, and when the latter overflows unable to take the influx, the sewage enters the parallel stormwater drains on OMR.

On the jap aspect of OMR, sewage motion is swift (because the pure circulation is in direction of the east) ultimately draining into the Buckingham Canal.

Bear in mind, what drains into the waterway is untreated sewage.

On the western aspect, nonetheless, the ducts overflow because of restricted capability, resulting in frequent flooding. Overflow from ducts causes day by day flooding of sewage on Thiruvalluvar Avenue (which connects to OMR) between 8 a.m. and 10:30 a.m., the interval when the faucets are a lot in use and the flushing of bogs intense at PG hostels.

Different roads connecting to OMR are additionally impacted by this downside.

The streets affected by this observe embody Vembuliamman Koil Avenue, Thiruvalluvar Avenue and Egattur Natham Hyperlink Street.

Residents of round 10 gated communities collectively accounting for 1000 to 1500 items must take Egattur Natham Hyperlink Street to enter OMR. Regardless of having their very own sewage therapy programs, all these communities are unnecesaarily hit by the issue of sewage overflows. And that is additionally not excellent news for the Buckingham Canal: quaffing untreated sewage would make it extra polluted. Civic intervention that must be undertaken instantly embody imposing use of septic tanks by PG hostels and particular person homes, stopping additional misuse of rainwater drains and repair ducts, and creating a normal underground drainage system for the stretch.
