The Challenge

Mod­ern mechan­i­cal flow reg­u­la­tors are being spec­i­fied in increas­ing num­bers to con­trol exces­sive flows with­in the sew­er­age sys­tems. The ide­al is where the flow curve is per­pen­dic­u­lar pro­vid­ing a con­stant dis­charge which opti­mis­es the per­mit­ted down­stream flow rate and min­imis­es upstream reten­tion. These reg­u­lat­ing devices are required to pro­vide pre­cise dis­charge con­trol through­out the reg­u­lat­ing range to min­imise the cost of stor­age pro­vi­sion. Stein­hardt flow reg­u­la­tors oper­ate safe­ly under these very dif­fi­cult con­di­tions and pro­vide pre­cise dis­charge con­trol through-out the reg­u­lat­ing range.

The Solution

The auto­mat­ic HydroSlide® Type Com­bi Flow Reg­u­la­tor is avail­able as Stan­dard (CS) mod­el or as the Flat­Flow (CN). Both mod­els com­bine many func­tions in one unit: they can be installed on the cham­ber inlet (semi-dry) or cham­ber out­let (wet), from raw sewage to stormwa­ter and, where there is restrict­ed space, with­in the cham­ber. The reg­u­la­tor hous­ing pro­tects the con­trol mech­a­nism so that no dam­age is suf­fered if the unit is sub­merged. An inspec­tion open­ing, even if sel­dom nec­es­sary, allows for easy main­te­nance. On small­er mod­els there are two hoses which are tak­en to the access cov­er. One hose is a breather to per­mit the inter­nal float to rise and fall; the oth­er is a flush­ing hose which per­mits the inter­nal mech­a­nism to be cleaned if required. Small­er units are also fit­ted with a man­u­al pull cable to open the ori­fice ful­ly if required. These units have an auto­mat­ic block­age release func­tion and are suit­able for use with­in foul sew­er­age systems.

The Advantages

  • semi-dry or wet installation
  • con­stant dis­charge (+5%)
  • the out­stand­ing fea­ture of the HydroSlide Type Com­bi is the auto­mat­ic block­age recog­ni­tion and clearance
  • both mod­els suit­able for low impound­ing heights
  • easy to clean, low maintenance
  • no exter­nal pow­er source required
  • oper­a­ble from above ground
  • no sole jump required
  • can be com­plete­ly closed off (option­al)
  • semi-dry ver­sion with vor­tex-inhibit­ing inlet pipe
  • small and compact
  • stain­less steel, so robust and durable
  • con­nec­tion for hose flush clean­ing from above ground
  • pull cable for man­u­al open­ing up to DR 250

Cost effectiveness

  • low-cost
  • can be opti­mised for local requirements
  • prac­ti­cal­ly maintenance-free
