Is insufficient wastewater treatment capacity holding back growth in your community?
Insufficient wastewater treatment capacity can easily become the bottleneck to community growth. Most communities tackle the problem at the treatment plant and opt for complex upgrades or an entirely new facility. Unfortunately these can be costly and time-consuming processes as teams conduct studies, obtain permits, select vendors and complete construction.
But there’s a faster and simpler solution from Clearford that turns the conventional approach upside down and eliminates the need for capital upgrades at the plant. Instead of making the plant do more, the Clearford process leverages the collection system to handle much of the pretreatment and dramatically reduce flow volumes and nutrient loading to the treatment plant.
In many cases, Clearford infrastructure can help avoid project delays, extend the life of the treatment plant by many years and bring about operational savings, even as the community grows.
The process starts by adding an underground ClearDigest™ smart digester for each residential connection as infrastructure is installed in a subdivision. This simple component plays a major role in reducing wastewater volume and load to the treatment plant. A smart digester can remove up to 75% of the solids and as much as 65% of the COD and BOD in wastewater. A patented mixing vent uses the energy of the inflow to gently agitate the solids and enhance decomposition. The process works so well that a ClearDigest system can operate for 10 years or more before a pump out is needed.
ClearDigest also modulates flow to the ClearConvey™ sewer system, which helps to deliver effluent to the plant with predictable characteristics and to limit peak flows. Unlike a conventional concrete or metallic sewer, the Clearford system uses sealed, flexible HDPE pipes that are impervious to groundwater infiltration and resistant to damage from ground movement. This alone, can significantly reduce the volume of water that reaches the treatment plant.
The reduction of solids in the collection system also means that sewer pipes can be sized smaller and can maintain cleansing velocity with lower slope. This translates into major savings in capital and installation costs by minimizing excavation costs and reducing the number of pumping stations as compared to conventional sewers. Plant headworks also benefit since no screening or primary settling is required for inflow from the ClearConvey sewer. In fact, the low solids content means that Clearford ClearRecover™ treatment plants are often built without any headworks whatsoever.
A comparison of a conventional sewer (top) vs the Clearford ClearConvey, which can be buried at lower depth,
requires lower slope and fewer pumping stations.
In many cases, municipalities can take advantage of Clearford’s Pay-for-Performance (P4P) financing program, which provides new wastewater infrastructure without taking on decades of debt or risky construction and performance promises. The P4P model enables municipalities to pay only for results, through a monthly fee for each connection to the Clearford One system, which covers all aspects of the system including construction, operation and maintenance.
