SaniCalc allows the user to design sanitary drainage systems. The programme is based on the Colebrook-White equation and provides flow and velocity data for both the full and partially full pipe condition

Sanicalc drainage design software
StackCalc allows the user to design sanitary stack systems. This programme makes it simple to size sanitary stacks, stack branches and branch drains connecting stacks to external drains.

T-BlockCalc allows the user to design thrust blocks for pressure pipes. The user can calculate the size of thrust blocks for a range of pipe types, sizes, bends angles, tees, reducers and soil conditions.
T-Blockcalc thrust block design software
VacCalc allows the user to size all the major components of a vacuum drainage system including vacuum piping, generators, vessels, pump suction piping, discharge pumps and discharge piping.

WaterCalc allows the user to design gravity water supply networks.

This software can be used for individual properties supplied from a roof tank or elevated tank or a group of buildings supplied from a common elevated reservoir.

Watercalc gravity water supply design software

This software is suitable for civil, sanitary, plumbing, drainage, public health, environmental and water service engineers together with students and teaching staff. This software can be used by contractors, consultants and local authority staff. Because of the low cost of these powerful software products it can be purchased for use on smaller projects where it would not be cost effective to purchase the much more expensive CAD integrated products sold by our competitors. These packages can be used by contractors to check consultants design packages. As stand alone packages they can be used to check paper drawings.

SoakCalc allows the user to design soakaways for both sanitary and storm water drainage systems. This software can be used for individual properties, packaged treatment systems, paved areas and highway drainage systems.

Gascalc natural gas piping design software

Gascalc allows the user to size low pressure natural gas piping from the gas meter to the various appliances. Gascalc  allows the user to select from various pipe materials and pipe diameters up to 200 mm.
