Sentinel Pit Advantages

  • Robust

    Sentinel pits were designed to suit the urban environment. They are manufactured from concrete and fitted with either a Class B or D load rated grate.

  • High Performance

    Enviss pits have high treatment performance for a range of pollutants including suspended solids, nitrogen, phosphorus, heavy metals and hydrocarbons.

  • Save Time

    Design time is reduced as every Sentinel pit is the same. Calculate the number of pits required and then move on to detailing the pit installation – no media or planting specifications required.

  • Durable

    As Enviss pits don’t use vegetation or biological treatment processes, the pits can withstand long dry periods without maintenance. And they will work when the next storm occurs, no leaching.

  • Tested and Verified

    The Enviss media was developed and tested by Monash University, a leader in WSUD treatment and technology. The research has been published in peer reviewed international journals.

  • Simple Installation

    Every pit is delivered complete and ready to install. Lift into position and connect the outlet. No specialist contractor is required as all work can be carried out by plumbers.
