Annular Space Grouting. As the nation's pipeline infrastructure continues to age, more emphasis must be placed on repairing these underground systems. Sliplining and relining are two solutions that allow the installation of new pipe without having to dig a new trench. The existing pipe becomes âthe hostâ for a new carrier pipe which is slipped into place. The annular space between the two pipes is then grouted to protect against shock and corrosion. The result is a âgood as newâ pipeline installed at substantial savings compared to traditional installation methods.
Typical Costs for a single house. 1  Plant Cost = Â£1800 to Â£3200. 2  Installation Cost = Â£2000 to Â£3000+ (depending on the model.). 3  Land drainage system (assuming 100 metres of drains) = Â£5200 or Â£200 typical cost if to a ditch with a 10 metre pipe run.
The cost of combineseed harvest, $20 per acre, was added to variablecosts, and stalk yields were lowered to 2.5 tons peracre with a price of $75 per ton. Again, most of thenet returns are negative except for the highestyield/price combinations (table 11) (Ehrensing).hus, potential returnsfor hemp fiber ranged from a low price/low yield esti-mate of $170 per acre to a high price/high yield returnof $759 per acre (table 8). With estimated productionexpenses of $286, net returns for hemp for fiberranged from -$116 to $473 per acre.
